Machine Design Feature
iGrind Operation
High speed box type dressing.
With EGM high speed box type dressing function, it drastically reduces the wheel dressing time.
This function allows the operator to input the specifications of the dresser and the geometric data of the profile to create the optimal dressing path.

Complete one piece cartridge spindle can avoid the eccentricity of spindle housing and reduces the heat increase for spindle life.
Spindle driven by servo motor offers optimum speed and torque performance.
Low-gravity base structure, with slant bed design for better coolant draining and grinding swarf removal.
We add in a vertical slide mechanical structure. You can chose general grinding wheel or diamond grinding wheel grinding the end face of the spindle and the two surface planes of the locating key with touch probe to achieve automatic positioning and automatic grinding.
