  • Automatic tool changer (ATC): 32 positions
  • Tool changing time: 3 seconds approximately
  • Laser measuring system for tool measurement
  • Touch probe system for workpiece measurement
  • Macro-video microscope for viewing operation
  • Optical microscope: 30X
  • Lubrication: oil mist / flood
  • Five-axis simultaneous control
Machining that can be carried out:
  • Drilling: 0.04 mm onwards
  • Tapping: 0.4 mm onwards
  • End-milling: 0.1 mm onwards
Time taken for each Machining Operation:

The time taken for machining depends on the nature of the profile to be machined. The feed and speed depend on the workpiece material. For 5-axis profile machining, it would take approximately 5 hours after carrying out the following initial tasks.

  • Dry run and calibration of machine tool.
  • Cutting tool measurement and calibration using Laser system.
  • Clamping of work piece on the table using fixture.
  • Setting up Datum using the touch probe.
  • Preparation of CAM Programming.
Time available for other users (Days / hours) : 3 Hours/day

(Micro tools need to be purchased by the user based on the holes/profile to be machined)
