Main uses and structural characteristics of machine tools:
● The machine tool is a two axis (x-axis is transverse feeding of grinding wheel frame and z-axis is longitudinal movement of worktable two linkage CNC cylindrical grinding machine.The CNC system adopts international or domestic well-known brands.It has the functions of automatic feed,withdrawal,rough grinding,fine grinding,dressing of grinding wheel,automatic compensation and so on.With optional automatic measuring instrument,it can realize the full closed-loop function of grinding cycle.
● The grinding wheel spindle adopts sleeve type or dynamic and static pressure spindle,the grinding wheel frame guide rail adopts steel guide rail,the worktable guide rail adopts Flat-V plastic lubrication guide rail,and the servo motor ball screw is used to drive the feed mechanism and the worktable to move.
● The main body of the machine tool is cast by cast iron,with a fully enclosed protective cover,a backpack type electrical cabinet in the rear and a rotary operation screen in the front
