Technicians disassemble the spindle and clean all components. We inspect bearing races, housing bores, shafts, seals, and other components to identify wear patterns and determine the causes of failure.
MMK Matsumoto has manufactured precision workholding equipment since 1948, producing CNC rotary tables, chucks, and hydraulic cylinders for machine tool applications. The company serves a wide range of industries with equipment that performs milling, grinding, electrical discharge machining (EDM), waterjet, and laser machining operations. MMK rotary tables utilize precision spindles with proprietary high-rigidity bearings and worm gear assemblies, enabling accurate indexing and positioning during multi-axis machining.
Setco repairs and rebuilds MMK spindles to meet original manufacturer specifications.
See the difference quality makes. Our before and after photos show the care and precision that go into every MMK spindle repair. From damaged or worn components to fully restored, like-new condition — we bring your spindle back to peak performance, helping you avoid costly downtime and get back to production faster.

When spindle bearings begin underperforming in CNC equipment, the indexing accuracy suffers and positioning errors start showing up during setups. These issues typically appear initially as quality problems with finished parts, requiring rework or scrapping. Besides affecting production quality, a failing spindle can put extensive strain on machine tools and cause days of unplanned downtime.
Worn spindle bearings create vibration during rotation, which affects the surface finish quality of a part. Damaged seals allow cutting fluids and debris to enter bearing assemblies, accelerating wear and causing premature failure. Spindles that bind during rotation or fail to hold position under cutting loads can damage internal components and lead to potential safety hazards.
Unusual heat buildup in the rotary table housing signals inadequate lubrication or bearing damage. Grinding or clicking sounds during indexing movements indicate bearing race damage that requires immediate attention. Catching these problems early helps keep equipment productive while preventing complete failure.
Setco provides comprehensive support for MMK spindle repair projects, helping shops minimize downtime and optimize operational efficiency. Specific benefits include:
Setco provides precise and reliable MMK spindle repairs by following a detailed, step-by-step process:
Technicians disassemble the spindle and clean all components. We inspect bearing races, housing bores, shafts, seals, and other components to identify wear patterns and determine the causes of failure.
Customers receive written estimates detailing required work and costs with no hidden charges. The quote breaks down exactly what repairs are necessary before work begins.
Worn parts are replaced with high-quality components that meet OEM specifications. We regrind and refinish shafts, install new bearings with correct preload, machine housings to restore proper tolerances, and replace all seals and electrical components as needed.
Rebuilt spindles operate at full speed with thermal stabilization while we monitor vibration levels and record performance data. Testing continues until the spindle operates within OEM specs. All measurements get archived by serial number for warranty purposes.
Finished spindles receive final inspection and ship with warranty information, parts lists, and test results.
Don’t let MMK spindle problems compromise production efficiency or accuracy. Setco’s repair services deliver proven results to restore performance. Contact us online or call for a repair quote and evaluation today.
