Optical Curved Profile Grinding Technology for Small Precision Parts

Optical Curve Profile Grinder is also called Profile Grinding Machine (abbr.: PG).

It provides high quality guarantee for the curve profile grinding of special-shaped precision parts and can get a mirror surface effect.

The machining precision can reach +/-0.001mm(1μm).

The surface roughness can be made Ra0.05.

It is suitable for processing various precision components for micro metal stamping dies and punching tools.

It is especially suitable for machining hard metal complex components in cemented tungsten carbide or high-speed Speed(HSS) Materials.

CNC Centerless Grinding and External and Internal Cylindrical Grinding Technology

Centerless Grinding for Cylindrical Parts:

The true roundness can reach up to 0.001mm.

The surface roughness can reach within the Ra0.05mm.

The accuracy can reach 0.001mm.

External and Internal Cylindrical Grinding/Turning:

Processing Range: within Φ320m。

Machining Accuracy can reach 0.002mm.

Precision Plane Surface Grinding Technology

The precision plane grinders are also called precision surface grinding machines.

They are mainly used for precision machining of shape finishing and surface parallelism and finish.

The maximum finish is R0.05;

Machining accuracy can be controlled within +-1um;

The minimum groove is 0.07mm;

The best clearance angle is R0.01.

It can satisfy all kinds of ultra-precision micro metal stamping die components processing.

Wire Cut EDM (WEDM) Machining Technology

Seibu High precision WEDM M50B and Sodick WEDM AQ360LXs.

WEDM is also called Wire-Cut EDM, or called Erosion Machining.

There is also a high-end wire-cut in oil, it is can be called oil-cutting that can get ultra-precision good R angle.

Processing accuracy up to +/-2um; Finish up to Ra0.31;

Min.line diameter 0.07mm;

Best clearance angle R0.06.

It can satisfy all kinds of complex mold inserts/inlays or special cavity parts ultra-fine processing.
