Features of KRG-series

  • 1)Both center processing, combined R processing, wet processing.
  • 2)Irregularity processing with setting the work piece on the swivel base.
  • 3)It is possible to handle interrupt by manual pulse generator(2axis).
  • 4)The setting and measuring are available with the large size projector / digital CCD camera.
  • 5)It allows processing time to be shorter, and unmanned operation.

Measurement example of double R-lapping processing

Besides high precision lapping used of the rotary dresser, it is also used high precision forming of V-face diamond wheel, and formed grinding of high-hardness materials.

Measurement example

The swivel base enables to process the submicron circular arc processing.

Measurement example of submicron circular arc processing

The swivel base that is high rigidity and precision is unequaled makes possible to process the submicron circular arc.(a figure drawn on the left side of processing example)


The High Rigidity Guaranteed

We put our know-how of machine development, and guarantee the high rigidity of the bed and whole machine structure.

The machine is high rigidity and low oscillation;the machine body is complete-box-type-structure and a bed filled up with concrete. The highly accuracy linear roller way are used on the table slide . It enable to have a rigid body and an accuracy movement.

High-performance Control Function

Manual pulse generator (2 axis) is equipped as a standard.

Auto-handle interrupt is possible, and you can bring out the skilful work.

Normal Direction Controlled

On programmed operation, control the axis to make the dresser for processing turn to normal directon at all time. It makes possible to perform the precise profile machini
