Operation
This CNC valve ball grinding machine by means of the simultaneously rotating of the balls and the grinding plates to lap the ball surface
*Machine X direction movement to centralize the ball
*Machine Z direction movement to precisely control the ball dimension
*Through end frame movement and replace the rotating grinding plate in order to lap difference specification of the balls from 1’’-48’’
*With the hydraulic device to support the balls and top end stretch
*Top end and balls simultaneously rotating, eliminate the balls and the top end relative movement.
