usage and structural performance
This machine is widely used for grinding of aerospace industry, military industry, equipment manufacturing, precision measuring tool,mould, electric components,hardware steel parts,casting and non-ferrous metal material.Especially suitable for batch production of polyhedral processing of guideway of lateh production enterprise.
This machine uses invention patent technology. It adopts gantry column, the apron make machine has good stability and strong power.
This machine adopts non-interfering horizontal and vertical wheelheads which realizes auto control of up and down and cross feed of the two wheelheads, and flat surface, guide surface,curved surface machining can be done in one-time clamping which improved working accuracy and efficiency.
It adopts independent oil station. Longitudinal travel of table droved by hyraulic, and stepless speed. It has hydraulic angle grinding wheel dresser for wheel dressing when grind guideway.
Vertical wheelhead can rotate 120 degrees in the vertical plane. It adopts precie FAC rolling bearing stucture with hig precision and suitable for various size of grinding wheel
