■ Dedicated Machining

For Stator Housing/Bearing Mounting Hole Drilling

Special Composite Boring Tools

・Composite tools realise excellent machining accuracy and dramatically reduced cycle time
・Optimised balance between tool weight and rigidity based on advanced stress analysis and actual performance data
For Simultaneous Machining of Grooves

Slotting Tools

Multi-tooth tools dramatically reduce grooving cycle time
Based on stress analysis, tools are both lightweight and rigid.

■ Dedicated Machining

For Bearing Mounting Hole Drilling

1-Pass Roughing and Finishing Tools
Cartridge type

The use of three formed inserts enables one-pass finishing even with pre-cast hole materials with large allowance variations
The introduction of a parallel adjustment mechanism maintains high perpendicular accuracy even when diameter height is adjusted
The use of an aluminum alloy body also enables use on small machining centres with cutter weight limitations
For Bearing Mounting Hole Drilling

1-Pass Roughing and Finishing Tools
Brazed type

By brazing the PCD edges directly to the body, the number of effective cutting teeth on the formed cutter can be increased (from 3 to 6), achieving even higher efficiency machining
