spherical valve grinding machine

Ball valve grinding machine Table size:Dia.550mm. Max.load.800kg. Special machine for valve. spherical valve grinding machineSMG series CNC sphere grinding machine is a new type machine.The surface grinding can be automatic continuously finished during one set-up. The machine is suitable to sphere precision grinding. T-type structure is applied to the base and frame-type strcture is appliedto the column, they ensure high strength and high rigidity. The originalcreation bran-new structure design has obtained national patent. The product possess perfect performance, and all accuracy are higherthan national standard. The machine is consisted of bed, column, headstock,slide basa and CNCrotary worktable which is fixed on the slide base. Workpiece is fixed onthe worktable and rotates along with the worktable. Sphere grinding isaccomplished through rotation movement of worktable and wheelheadthat isinstalled on the spindle.Parameters and configuration
