H-2 axes/B-3 axes CNC Surface grinders, the main structure is analyzed by the finite element technique with different combination of external forces to ensure the stiffness of the machine. The base of the grinder is expanded for the purpose of increasing the supporting capability and stability of the machine. A fully-supported rail design reinforces the precision and stability. SIEMENS brand CNC controller, operation more convenience. A special joy stick is designed to control the axial movement to facilitate the operation. In addition with Auto wheel dressing and compensation function & roller dressing device for increasing more processing efficiency.
