Great productivity by improving manufacturing speed.

Achieved 6times faster manufacturing speed by changing to our honing stones
and manufacturing process. Reduced wastes and stabilized plating treatment.

comparison with manufacturing time

Changing honing stones & manufacturing process

It took 6hours(360min) to grind one workpiece with WA stone before. Only one workpiece was manufactured per day.
We achieved 6 times faster manufacturing speed by changing manufacturing process from 1 to 2 with our grinding stones.
By using our products with low machine pressure, deformation of the workpiece was improved.
Manufacturing speed was able to be faster due to stable cutting ability of our grinding stones.

Sludge reduction and stable grinding accuracy

Due to small wear of our grinding stones compared with WA stone, the amount of sludge from our grinding stone was 1/25 smaller.
By reducing wastes, grinding process was held with clean coolant.
Plating treatment after grinding process was stable due to stable cutting ability of our grinding stones.
