Cartridge Spindles

Cartridge spindles are a popular category of machine tool spindles. They are high speed spindles based on cartridge type housing and used in a variety of applications. These spindle assemblies are supplied by manufacturers as complete headstock assemblies with the cartridge spindle mounted in a headstock with collet actuators, chuck actuators, pulleys etc. Cartridge spindles are used with innumerable standard work holding fixtures like collets, jaw chucks and any special fixtures.


Feature of cartridge spindles

• These spindles are designed for use in a variety of mounting platforms either horizontal or vertical.
  
  
• They are available with American Standard noses like A2-3 and A2-5 and other varieties as well.
  
  
• They are high speed spindles capable of performing at very high RPMs.
  
  
• They can be easily incorporated into custom machines.
  
  
• There are built-in air purge in such spindles which keeps coolant, chips out of the spindle mechanism.
