ROW Diamond Wire

The main feature

A high-speed cutting is possible

5-10 times faster slicing comparing to loose abrasive wire.（2-5 times faster than resin bonded wire）

possible to highly accurate process

Strong diamond wire that achieves accurate and precise slicing.

Uniting material

A metal bonding material does not limit coolant types.

abrasive coating centralized control

Diamond concentration is controllable.

Long life structure

High diamond exposure(50% up against our conventional type),Long tool life
