Fully unmanned operation of mass production
even for complex-shaped workpieces
Single-disk (bottom) grinding machine HSDB-250

Features of Machine

01 Accommodates complex-shaped workpieces

Bottom grinding of cemented carbide inserts for Wavemill, one side grinding of complex-shaped workpieces, etc. which cannot be handled by an ordinary surface grinding machine, can be accommodated.

02 Simultaneous machining of 2 workpieces for higher productivity

Sufficient rigidity provided for the grinding wheel spindle shaft, the rocking shaft and the workpiece presser shaft enables simultaneous machining for 2 workpieces.

03 Automatic transfer of workpieces

The transfer robot and the pallet stacking device enable the fully automatic process of workpieces.
The automatic dressing unit, provided as standard issue, stabilizes machining precision and keeps the grinding wheels in good condition. Also, the automatic thickness measurement system for workpieces provides real-time feedback of measurement results.
The full automation of transfer, machining, measurement and dressing enables fully unmanned mass production.
