Note : 1.Above is a recommendation in general. Because roll grinding is a kind of precision grinding, it requires great grinding experiences and skills. One must consider the material of workpiece, machine's conditions and speed etc., to have a right choice of grinding wheel specification.

2.Usually, roll grinding machines allow to change wheel speed. General max.
operating speeds for vitrified wheels are 2000 m/min(35m/s), and for resinoid
wheels are 3000 m/min(50 m/s)
