Top Spindle Issues and Their Causes
Understanding the common spindle issues and their primary causes is key to rapidly addressing and resolving them. Below are some of the most prevalent problems encountered:
Extreme spindle vibration refers to an abnormal level of oscillation or shaking during operation. This problem typically results in poor surface finishes on machined parts, heightened mechanical stress on different components, and decreased tool lifespan. Possible causes include unbalanced rotating parts, worn bearings, or improper tool holder installation.
When the operating temperature exceeds the recommended or normal range, excessive heat can harm the component’s performance, accuracy, and longevity. Factors that can contribute to this issue include improper cooling systems, inadequate lubrication, excessive cutting speeds, or incorrect tool selection.
Spindle Bearing Failure
Bearings are critical components that support and facilitate smooth rotation within the spindle assembly. A malfunction or breakdown in bearings can lead to compromised performance. This issue often happens due to inadequate lubrication, contamination, excessive loads, or improper handling during installation.
Runout is the extent of deviation or wobbling in the rotational axis of an operating spindle. It is a critical measurement that affects the precision and accuracy of machining processes. When a spindle exhibits runout, it can result in inaccuracies and inconsistencies in the machined workpieces. Causes of this issue include worn bearings, misalignment, damaged tool holders, or insufficient clamping force.
Spindle Repair Techniques
When a spindle encounters issues or malfunctions, it is essential to employ effective repair techniques to restore its functionality and avoid costly replacements. The following are some common methods utilized by professionals:
Balancing is a repair technique that addresses excessive vibration. It begins with the identification of imbalances in the rotating components of the spindle. Then, precise adjustments are made to redistribute the weight within the assembly. This can involve adding or removing material from specific locations or using counterweights to offset the imbalances.
Skilled technicians can diagnose bearing problems through careful inspection and analysis. They assess the condition of the bearings, checking for signs of wear, abnormal noise, excessive play, or any other indications of component failure. Bearing replacement involves removing faulty or worn bearings and installing new ones properly sized for the assembly.
Misalignment between the spindle and other components can result in runouts and inaccuracies in machining operations. Spindle repair professionals can adjust alignment using precision measurement tools to align the spindle with the machine axis. This technique restores the spindle’s concentricity and enhances accuracy.
A rebuild is a comprehensive repair technique employed when a spindle has experienced severe damage that cannot be addressed through simpler repair methods. This technique involves disassembling the spindle, replacing damaged components, and reassembling it to restore its original functionality. It also includes inspecting the parts, such as bearings, shafts, gears, and housings.

The CNC machining process produces complex machined parts with ease and precision. The entire operation relies on successfully integrating machine tools and equipment; therefore, you must maintain them in excellent condition. However, there is always the possibility that the machine tools will malfunction, particularly in continuous production.
The most commonly used tools and equipment for CNC machining are drills, lathes, and milling machines. There are also other modern technologies like laser, plasma, and waterjet cutters — all of which are susceptible to issues and malfunctions.
Here are some of the most common problems and issues with CNC machining tools and the basic solution for each:
Click to Expand
1. Incorrect Tools or Configurations
Using incorrect machining tools often produces substandard material manufacturing and finishes, including rough edges and burn marks. Consequently, this inaccuracy may deteriorate the equipment over time. Moreover, using a tool with the wrong dimensions in terms of size, quality, or compatibility with the material might result in equipment failure.
Understanding the applications and differences between different tools is the first step in resolving this issue. This will help you choose the right machines and equipment for your CNC machining task.
2. Programming Errors
Specialized computers operate every CNC machine, and inaccurate programming may reduce the machining process’ quality and efficiency. Typically, this issue is caused by the operator’s misunderstanding of the implemented codes. A solution for this problem is properly training operators in all aspects of the tools.
3. Poor Equipment Maintenance
Failure to maintain a regular maintenance schedule for the machinery may result in inaccuracies and problems that build up over time. Therefore, operators must adhere to strict maintenance routines for in-service tools and equipment to avoid this issue. Additionally, they should regularly inspect airflow or coolant levels to ensure that operations continue to run smoothly.
4. Power Supply Issues
Power supply issues could impair the performance of CNC machine tools. For instance, low power or voltage readings and blown fuses may lead to the complete failure of a machine. To prevent this, check the power supply’s input and ensure they have the correct voltage and capacity.
Continuously operating CNC machines frequently results in overheating, with temperatures exceeding 150 ℉. To prevent this, ensure that all lines are periodically cleaned and that the machine is free of dirt, soil, and debris.
6. Automatic Tool Changer Issues
A CNC machine tool utilizes an automated tool changer (ATC) to increase production and tool-carrying capacity. Unfortunately, ATC errors are common, leading to complications throughout the machining process.
A crucial step to resolving this issue is to inspect the base, tool holder, and support arm. ATC troubleshooting is also frequently coupled with a generic tool changer alarm. Lastly, determine the machine’s diagnostics and switches so that you can replace or repair them appropriately.
7. Machine Chatter or Vibration Issues
It is normal for machines to produce vibrations when in use, but if they begin to make unwanted sounds that grow louder over time, there is a complication. You can solve this by knowing whether or not your tool chatters. In that case, consider adjusting the RPM such that its frequencies do not resonate with the material frequency.
8. Clamping or Unclamping of Chucks and Fixtures
Chucks and fixtures become loose with time, causing the spindle to lose its grip on the fittings. This can cause the machine tool to vibrate during the machining operation. This clamping and unclamping may result in poor construction of the machined product and even operator injuries. To address this, verify that all parts are properly positioned to ensure adequate clamping.
9. Insufficient Worker Skills and Training
Machining errors may be related to the personnel’s lack of training and expertise. Their skill sets may be outdated, posing a challenge for new and creative CNC machines and processes. To resolve this problem, all workers must undergo updated and comprehensive training to develop management and technical skills.
10. Burnt Traces on the Relay Board
Relay boards are computer circuit boards containing an assortment of switches; they are equipped with input and output terminals to regulate the voltage supply. If you detect that one of the traces on a relay board has been burned, you must de-solder the burnt tracing wire and replace it with a new one.

Possible Causes of Spindle Failure and How To Avoid Them
Some factors not associated with a spindle’s expected lifespan may cause it to fail prematurely. However, you must know the indications that your component is failing before requesting a repair or replacement. For example, wear and tear are common when the tool holder slips within the spindle. Other signs include external noises, loose connections, or spindles that become significantly hotter during operations.
The following are some of the most common reasons why a spindle fails before a total part collapse:
Poor Lubrication Application
Poor lubrication is one of the most frequent causes of spindle failure. Bearings are prone to overheating when subjected to extreme operation and can completely collapse if not adequately lubricated.
Moreover, improper application of lubricants — either too much or too little — can cause component malfunction. For example, bearings can seize if there is insufficient lubrication, while they might overheat and fail if there is too much. The subsequent bearing damage can include tapered roller deterioration, raceway breakdown, and cage fragmentation.
Here are three things to remember about lubrication to ensure longer bearing life:
Always use the proper lubricant type. Since there are different types of bearing grease and oil, it is critical to find which has the right consistency and viscosity for your components.
Always apply the right amount of lubricant. Inadequate lubrication can damage your bearings, but too many fluids can also pose complications. Make sure to follow your machine’s lubricant specifications to extend the life of your bearings.
Always use lubricant at the proper time. Even if you use the correct type and amount, applying it too frequently or rarely can cause bearing failure. Following a lubrication routine will ensure peak performance.
Improper Installation or Removal
This cause of failure can occur if the spindle is not properly installed or removed. Improper installation or removal can also cause bearings, shafts, and other components to be damaged. Moreover, any shock load to the spindle can cause brinelling or the permanent indentation of a bearing surface.
Using the right tools in a clean work environment is critical to ensure proper installation. It is also important to take time installing the parts because estimating or eyeballing their locations may cause significant damage to the components. Lastly, hire a professional if necessary; someone you trust with expert knowledge and experience can assist in properly installing or removing your spindles.
Contamination encompasses foreign substances and water, infiltration through seals, improperly stored or poor-quality lubricants, and inadequate assembly.
To combat this problem, you should use clean and dry compressed air for air-oil lubrication systems. An annual air system inspection is also recommended because preventing debris accumulation on seals extends their useful life and reduces bearing contamination. Moreover, install seals according to manufacturer instructions.
Mishandling and Storage Mistakes
Mishandling may include dropping the spindle or exposing it to excessive shock loads. In addition, improper storage can cause failure because temperature fluctuations and high relative humidity can cause the spindle to rust or corrode.
To prevent condensation from accumulating, you should maintain a low-humidity storage area for spindles. It is also best to keep spindles dry in areas where the temperature does not fluctuate between 65 ℉ and 120 ℉.

The spindle is considered the machine’s heart and is usually designed with its application and precise specifications in mind. However, whether used for grinding, turning, or milling, different types of spindles experience various failures or breakdowns. These necessitate varying repair procedures, frequently resulting in unnecessary spindle repair costs.
Nonetheless, it is possible to avoid spindle failure, extend your spindle’s life, and optimize efficiency and output by following simple guidelines. While all spindles have a finite lifespan, proper maintenance prolongs their usability, making them more cost-effective in the long run.
This article will cover essential tips for maximizing the life of different spindle types — grinding, milling, and lathe.

What Are the Different Spindle Types?
Different types of spindles are used for various applications. Hence, you must first understand the type of spindle used for each application to fully understand how to extend their life.
Grinding spindles are used for applications ranging from rough shop bench grinding to precise CNC machining. They are also used to work with materials such as metal, plastic, stone, wood, glass, and polymer blends. You can use several kinds of spindles as grinding spindles, including the following:
Motorized spindles that equip traditional grinding wheels for grinding tasks
Traditional grinders for CBN grinding wheels
CNC-controlled motorized spindles
Milling spindles are often used to cut a workpiece. The milling tool is usually accommodated by other devices, such as hollow shaft tapers (HSK) or quick-release tapers (SK). The most common types of spindles for milling include belt-driven spindles, direct-drive spindles, and motorized spindles.
The lathe spindle connects the headstock to the axle of the lathe engine. Like the other types, these spindles are used for machine-cutting parts and components.
Lathe spindles are available in several kinds. Belt-driven spindles are standard on older lathes; they take longer to spin up and slow down. On modern lathes, however, direct-drive spindles are standard. They can achieve top spindle speeds up to twice as fast as belt-drive models, making them ideal for high-volume manufacturing.
How Do You Extend Your Spindle’s Life?
Whether you have a grinding spindle, milling spindle, or lathe spindle, improving the spindle’s life requires a careful combination of proper care and a thorough understanding of the component. In addition to professional-level preventative maintenance and inspection, the following basic guidelines can help reduce downtime and save money on CNC spindle repair or replacement:
1. Always Check for Spindle Taper Wear or “Bell Mouth”
It is critical to perform regular checks on the spindle taper, which is the part that wears the quickest. It is exposed to the elements and the most easily damaged by metal shavings and debris.
You can check for defects in the taper by measuring total indicated runout (TIR) in the taper and also measuring TIR over a precision test bar. The TIR or the Total Indicated Runout means the distance measured between the biggest plus measurement and the smallest minus measurement for the total amount indicated. If the measurement differs significantly, you may have a problem at hand.
You can also blue up a known good toolholder and use it to check in the spindle. Setting aside a toolholder for this testing is recommended to ensure that it is a valuable and pertinent reference. If you get less than 75% contact with the taper, there is a problem.
2. Examine the Toolholder for Fretting and Taper Wear
Excessive and potentially serious wear occurs when a toolholder slips within the spindle. A good spindle taper does not always imply a good toolholder taper. If your spindle taper is more rigid than your toolholder tapers, they should bear the brunt of the wear. Begin by carefully inspecting your toolholders for minor scratches and discoloration, especially near the big end. Moreover, keep an eye out for fretting wear, which occurs when two steel parts rub against each other.
3. Regularly Check Pull Studs for Signs of Wear or Damage
Pull studs, also known as retention knobs, are consumable parts that are screwed into the top of a toolholder. It is held in place by either a finger or a ball-bearing gripper. The drawbar then grips the pull stud to tighten the toolholder into the spindle taper.
A pull stud has an average lifespan of two to three years. However, this can considerably shorten, depending on the damage it endures. Thus, it is vital to regularly check your pull studs for wear, cracks, or other damage and replace those in poor condition. When replacing a pull stud, clean and degrease the thread, then apply thread locking compound (low or medium force, not high force) and torque to specifications.
4. Keep Everything Clean
Cleanliness is crucial for spindle and toolholder durability. Contaminants can cause poor TIR and influence the premature wear of several parts, so you must maintain the cleanliness of all toolholders, collets, collet nuts, and cutter shanks.
5. Check the Drawbar Force
Low drawbar force puts the spindle at risk. You could damage a toolholder by spinning it in the taper, or if the force is strong enough, the drawbar could lose grip and send the toolholder flying. On average, you should check the drawbar force every six months to ensure it will last one million cycles.
6. Ensure Adequate Lubrication and Vibration
Be on the lookout for excessive vibration. Any unusual vibration is a warning sign that something is wrong and should be investigated. If you have an air/oil lubricator, ensure the lubricants are clean and the air-intake filters are in good working order.

Spindle unit performance is critical to the quality of the machined parts and machine maintainability. It includes belt-driven, motor-integrated, and tool-driven spindles and is used in various machines ranging from high-speed milling to high-capacity turning processes. In essence, the spindle parts’ performance and the overall spindle unit determine the machine operation quality and equipment efficiency.
On the other hand, spindle failure is a common problem in any manufacturing or industrial setting, resulting in unprecedented downtime. There are several causes of spindle failure, and each requires a different approach to repair. Collisions with workpieces or bearing failures are the most common causes of spindle failure.
In this article, we will guide you through the different spindle parts and their common fixes and repairs in the event of a failure or breakdown.

SPINDLE PARTS OF A MACHINING SYSTEM
A spindle is a rotating axis of a machine with a shaft at its center. However, the term “spindle” is also used to refer to the entire rotating unit — including the shaft, bearings, and anything else attached to it. The spindle parts, as well as their standard fixes and repairs, are as follows:
A housing must hold the spindle shaft and motor in place. It could be built into a machine tool or a cartridge housing and mounted with a block, foot, or flange. Many high-speed spindle models use cartridge-type housings because they are the easiest to support and because high-speed tolerances are easier to achieve when the housing is manufactured as a cylinder.
This spindle part’s core purpose is to enclose the bearings. Therefore, it must precisely sustain and pinpoint the bearings while providing utilities to the spindle system. It is also necessary for the housing to be solid and stiff because it transfers all forces from the spindle to the machine tool.
The most common problem with spindle housings is a lack of bearing-housing clearance at the rear of the unit, which can lead to excessive bearing preload and seizure. Housing bores or other defects on diameters can be corrected with chrome plating and grinding, which are offered by RMR Spindle Repair.
Any spindle design would be incomplete without a bearing system. The spindle must transfer torque and power to the cutting tool and have a reasonable loading and life. The bearing type must meet these specifications, or the spindle will not operate effectively.
There are various bearing types used with machine tool spindles. Some of them include the following:
Angular contact bearings
Ceramic hybrid bearings
Tapered roller bearings
Bearing failures are caused mainly by excessive preload (negative radial clearance), which may result in a high-bearing running temperature and seizure. Another failure is the angular contact bearings tolerance mismatch in which angular contact bearings with standard outer diameter (OD) tolerance may fail.
These can be repaired by replacing the bearings. It would also be beneficial if the spindles were reassembled with precision bearings identical to the original bearings installed.
Spindle designers use seals to prevent external contamination from entering the spindle unit. These seals are necessary because high-precision bearings are highly susceptible to contamination — from chips, dirt, dust, coolant, and other foreign material on the surfaces – usually causing premature failures.
When a seal fails, the most common solution is to replace it with another. Furthermore, protecting spindles in high-contamination areas necessitates a thorough examination of the spindle’s existing seals, with the ultimate goal of preventing contaminants from entering and destroying the bearings.
A standard belt-driven spindle setup consists of the spindle shaft, which is supported by the spindle housing and is held in place by a bearing system. In addition, the tooling system — tool taper, drawbar mechanism, and tool release system — is integrated into the spindle shaft.
The most common failure is shaft misalignment, usually caused by premature bearing, seal or coupling failure, excessive vibration, high housing temperature near the bearings, and excess oil leakage in the bearing seals. You can avoid these by regularly checking the shaft straightness or alignment relative to the tool side and avoiding excessive belt tension on belt-driven spindles.
If a total shaft failure occurs, RMR Spindle Repair is more than capable of cleaning, repairing, and — if necessary — chrome-plating your spindle shaft.
The spindle motor is mounted independently of the shaft. As a result, it is frequently possible to use a huge motor. A motor, especially one with a large diameter, can provide extremely high torque and power for spindle use. However, this is more difficult because available space is always limited in an integral motor spindle design. Typically, the rotor is attached to the spindle shaft via adhesive or thermal clamping, whereas the stator is the winding around which the rotor revolves.
Too high winding temperature is a common stator fault caused by too high voltage, a broken rotor cage bar, or water leakage from the water jacket. In the occurrence of a stator fault, RMR Spindle Repair provides stator cleaning, baking, testing, and rewinding.
As a machining operation, taper turning is the gradual reduction in diameter from one part of a cylindrical workpiece to another. A workpiece has an external taper if tapered on the outside; an internal taper if tapered on the inside.
A damaged taper, frequently resulting from simple wear and tear, can lead to complex mechanical problems. Straight marks on the taper indicating fretting are common signs of deterioration. Natural deterioration can lead to many more significant machining issues that you must address as soon as possible because the taper is subjected to high-speed conditions and frequent tool changes. Chrome plating is the most common solution for any taper fault.

Tips For Proper Spindle Care & Maintenance
Periodic predictive maintenance and inspection performed by professionals will help you reduce scrap, decrease downtime and save money on spindle repairs. Here are some tips to help you find and correct spindle problems before catastrophic failure and machine tool crashes.
It is crucial to a spindle’s longevity and overall performance to keep your lubricating fluids clean and at safe operating levels. Service the air-intake filters regularly if you have an air/oil spindle. Additionally, maintain spindle-bearing lubrication. It’s essential to keep the proper oil levels in these baths.
Gauge and test.
Assess your spindle’s runout every six months or after any crash via ground and calibrated spindle test bar. You can monitor your spindle’s spring force with a drawbar pull test.
Monitor spindle vibration levels.
If your machine has a built-in vibration sensing technology, pay attention to any alarms. Damaged spindle bearings usually cause more vibration, so replace them when necessary.
Check the cooling system.
If your spindle is high-speed and has a cooling system, ensure the chiller unit runs appropriately. A rise in the chiller system output temperature usually indicates a spindle problem. If this occurs, have a certified technician thoroughly check the system.
Keep the machine covers on.
Always re-install any machine covers that have been removed due to routine maintenance or any other reason. These covers protect the spindle area, keeping contaminants from infiltrating the spindle, its motor, and other components.
