Mounted Point Rubber Grinding Stones

Mounted Point rubber grinding stones are ideal for fields requiring precision and high accuracy, such as automotive parts, semiconductor
and electronics components,and mechanical parts like bearings. They are optimal for localized or deep grinding tasks,
such as internal surface grinding, groove bottom grinding, and hole machining, which are difficult to perform with standard grinding wheels.

Lineup

・In addition, we accept consultations regarding grit size, hardness, dimensions, etc., according to the application. Special shanks, such as shaft length specifications or 1.6 mm, 2.35 mm, 10 mm shafts, can also be discussed.
・The maximum allowable rotation speed varies depending on the size and grinding wheel material.
