Use and performance
This machine is widely used in the aerospace, military, automotive, equipment manufacturing, precision measuring tools, molds, electrical components, hardware steel, castings and non-ferrous materials grinding.
Fully implement the national standards and industry standards;
The surface grinder has good rigidity for its itegral bed,Gantry column and cross worktable
Longitudinal movement of worktable and crossfeed movement of wheelhead are driven by hydraulic in stepless speed regulation.,The surface grinder which has 2000mm or more than 2000mm working length adopt independent petrol station.
The wheelheade is driven by embedded motor,The vertical feed of wheelhead equipped with rapid lifting mechanism and manual lifting mechanism
