High speed aerostatic bearing spindle

Spindle speed: 60000 min-1
NRRO(*): 0.10 μm
TIR: 1 μm

(*) Measured with the method of Single Point Asynchronous Error Motion

High speed and low heat generation

  • Improvement of machining time
  • Reducing in the types of tools and the processes (small diameter tool use)
  • Low spindle thermal displacement (See the figure at right)

High rotational accuracy

  • Realization of high quality machined surface
  • Enhanced tool life

Virtually unlimited life of bearings

  • Availability of high speed, continuous machining
  • Reduction in the maintenance cost

Low level vibration and noise

  • Realization high quality machined surface
  • Improvement of the working environment

High precision contouring

High quality surface machined with high speed feedrate is realized, providing linear motor driving system for X, Y and Z axis.

  1. High quality and smooth machining around quadrant switching area realized, due to minimized lost motion.
  2. High quality flat surface realized, due to eliminating factors, for instance, influenced by a ball screw driving system.

Linear motor drive

High precision positioning and smooth feed

Reliable step feed 0.1 μm realized, providing 0.01 μm of programming resolution for X, Y and Z of linear 3 axes.
