Spindle repair with state-of-the-art measurement technology and analysis methods
Precise spindle repair begins with an accurate failure analysis. State-of-the-art measurement technology detects even the smallest deviations in concentricity, bearing load, and speed characteristics. This detailed diagnostics allows damage to be specifically addressed before major failures occur—regardless of whether the spindles are motor spindles, milling spindles, grinding spindles, turning spindles, robot spindles, or custom solutions from our product line.
After spindle repair, each unit undergoes extensive testing. Dynamic balancing tests and thermal analyses ensure that the spindle operates optimally once again . Our experts perform spindle repairs with the highest precision—from high-frequency milling spindles to high-speed grinding spindles and turning spindles —to ensure your machine runs stably and reliably.
Our spindle service team is always available to perform a spindle check for you. We also offer grinding spindle repairs, turning spindle repairs, milling spindle repairs, spindle bearing replacement, spindle maintenance, and spindle overhauls.

Spindle repair for optimized cutting force transmission
Precise power transmission is crucial for consistent machining quality. A professional CNC spindle repair ensures that torque and feed forces are optimally transmitted to the tool. Worn bearings, inaccurate clamping systems, or incorrect adjustments can impair the machine’s performance.
After a thorough analysis, we repair all relevant components and adjust bearings, shafts, clamping systems, and cooling circuits according to OEM specifications. Our experts repair motor spindles and milling spindles using state-of-the-art measurement technology, reduce energy losses, and stabilize the machining process. This increases productivity and extends the service life of your spindle.

Spindle Repair with Customized Maintenance Plans
Reliable CNC spindle repair is based on a thorough analysis and a spindle-specific maintenance plan. Each spindle system is subject to different loads and wear mechanisms that cannot be addressed by a standardized repair process. Regular inspections of tool spindles and targeted repair measures extend service life and increase the spindle’s process stability.
Our experts tailor each spindle to your operating conditions. Whether it’s spindle repair for milling machines, repair of grinding spindles, or repair of robot spindles — precise adjustments, the replacement of critical components, and complete documentation ensure consistent performance. A structured spindle repair or a comprehensive spindle repair service reduces downtime and stabilizes manufacturing processes.

Spindle repair with precise balancing and concentricity optimization
Proper concentricity is essential for a precise and durable spindle. A professional spindle repair includes the precise balancing of the rotor assembly and the correction of concentricity deviations. Imbalances cause vibrations, increase bearing load, and impair machining quality—especially in high-frequency milling spindles, high-speed grinding spindles, and high-rigidity turning spindles. Through precise machining and alignment of all components, these issues are identified and resolved.
Following the repair, ramp-up, vibration, and dimensional tests are performed. Our specialists perform spindle repairs using state-of-the-art technology to ensure the highest level of dimensional accuracy. A well-coordinated repair of milling spindles reduces wear and increases the efficiency of your machine.

Spindle repair for energy-efficient and stable production processes
Efficient repair of machine tool spindles reduces friction losses, stabilizes thermal behavior, and lowers the machine’s energy consumption. Worn bearings, increased friction torques, or uneven axial and radial forces lead to higher energy consumption and unstable processes. Through technically tailored repairs of all spindle types— motor spindles, milling spindles, grinding spindles, turning spindles, and robot spindles— these issues are specifically addressed.
Our experts perform precise CNC spindle repairs, minimize friction losses, and ensure operational reliability. Every spindle repair includes a comprehensive analysis, the replacement of worn components, and precise bearing adjustment. The result is consistent machining accuracy, lower operating costs, and consistently stable manufacturing processes.
