Single Surface Precision Lapping Machine type: SW-300 has been designed for the purpose of grinding high-brashness materials (Sappire, SiC, GaN, and so on) with high-preciseness in short time with ease.
Such items as grinding stone and axes are settled paleways on single line. The axis, on the way of grinding, moves back and forward over the materials. The back and forward movement gives grinding to very thin thickness and less damages. Maximum process-available 300mm diameter is able to make effective batch treatment and high productivity.

 Back & forward movement (upper axis)

The back & forward movement and forcible rotation of upper axis can afford to make less orientation on the surface of materials and precise lapping.

 Forcible-go-forward system

It is brand new system never seen before. You can take control the movement of upper axis to the limit of 0.05μ/s.
Collaborated action with the overload system the Forcible-go-forward system makes constant pressure to the material.

 Overload sensor system

Once the sensor acknowledges much overrode than that of set, the system gets the material plate back, releases overdue stress among wheel and material, and once start to grind.

 Zero-Touch System

Zero-Touch System is the function to come in touch with starting point without human's divination.

 Intermittent mode system

Lapping and getting interval time over and over again. In the interval time the system helps abrasive coating (grain) to work in between the material and plate and also helps lapping ratio go up.

 Control of thickness of the materials

Thickness of materials are always controllable by linier scale measurement reading system. The reading system reads distance of the linier scale of upper axis. The thickness control system gives operator no needs for operation of keeping flatness of the lapping plate.
Suppose and calculate measurement value, that was only way to get precise lapping value.
SHUWA's new lapping system does not need to suppose nor calculate!
