CNC SPINDLE REBUILD

Rubin Engineering & Sales rebuilds and services machine tool Spindles of all brands and types: motorized, non-motorized, coolant cooled, etc. We can also rebuild the Spindle’s Draw Bar simultaneously and reinstall it into the repaired Spindle.

Most Spindles can be turned-around in a matter of days, many times depending upon availability of necessary bearings.

Spindles are 100% tested from 0 to 100% of maximum rated RPM as well as actual operating RPM. Throughout testing, spindles are monitored for temperature, vibration, and nose-end run-out.

CNC Spindle Rebuild/Repair

Rubin Engineering & Sales rebuilds and services machine tool spindles of all brands and types: motorized, non-motorized, coolant-cooled, etc. We can also rebuild the spindle’s draw bar simultaneously and reinstall it to OEM specifications.

Most spindles can be rebuilt in a matter of days, depending upon availability of necessary bearings.

Spindles are fully tested from 0 to 100% of maximum rated RPM as well as actual operating RPM. Throughout testing, spindles are monitored for temperature, vibration, and nose-end run-out.

 

The Spindle Repair Process

There are five primary components involved in the CNC spindle repair process. These include:

  • Inspection and analysis. It’s important to perform an initial visual inspection to evaluate the condition of the spindle and check for external damage. Then the spindle is disassembled and inspected for signs of contamination, misuse, or other signs of failure. Each spindle component is inspected and analyzed to determine the root cause of spindle failure.
  • Repair. Damaged spindle components are rebuilt or reproduced using state-of-the-art equipment to ensure adherence to tight tolerances.
  • Balancing. Properly balanced spindles ensure improved performance and increased service life of bearings. Correcting imbalance issues involves removing or adding weight to the component.
  • Assembly. The repaired spindle is assembled with all new bearings and lubricant.
  • Testing. The spindle is thoroughly tested under typical and extreme operating conditions to ensure it meets or exceeds original specifications. 

 

Types of Spindle Repairs

There are various types of CNC spindle repairs. We offer the following spindle rebuilding and repair options:

  • Ball, roller, ceramic, hydrodynamic, and hydrostatic bearing spindles
  • PCB drill and engraving spindles
  • CNC milling, CNC drill, CNC lathe, and fine boring machine spindles
  • CNC surface, CNC tool and cutter, creep feed, and form grinder spindles
  • CNC router, high-speed router, shaper, molder, and high-speed electro spindles
  • Internal, internal-diameter, outer-diameter, external, centerless, and cylindrical grinder spindles
  • Wheel head, dresser, and work head spindles
  • Automatic tool change, Capto taper, Big Plus taper, DIN taper, HSK taper, and coolant-thru-spindle milling types with Morse taper spindles

 

Causes of Spindle Failure

Spindles fail for many reasons. Common causes of spindle failure include: 

  • Mishandling. A spindle that is installed or stored improperly can lead to damage.
  • Contamination. Improper seals can allow particles from machining and fluids such as coolants to contaminate the bearings.
  • Lubrication. Spindle bearings must have a proper mixture of oil lubricant and clean air to avoid premature failure. 
  • Balance. An imbalance can wear bearings prematurely.
  • Overloading. More load or speed than the spindle’s rating can significantly reduce the life of the spindle.
  • Pre-loading. Bearings loaded with more force than required can cause skidding and premature failure.
