7. The sliding surface of the machine is equipped with a centralized lubrication and oiling device to ensure the lubrication effect of the sliding surface and the feeding accuracy.

8. When the grinding wheel and spindle of the setting wheel are started, the oil pressure switch should be used to confirm that oil has penetrated into the bearings before it can be started to ensure safety protection for the spindle . The lubrication and hydraulic systems are driven by the same hydraulic pump, and an oil temperature cooling fan is installed to effectively reduce the rate of oil temperature increase.

9. The rotation angle of the upper skateboard is easy to adjust and the power supply is precise. It is suitable for stop-type grinding operations and can adjust the diameter of the front and rear sections of the workpiece. The grind stop can also be used to grind inclined workpieces. Adjust the rotation angle range +5°~-5°.

10. The dressing device is made of special alloy cast iron, fired and wear-resistant. It is hydraulically driven for forward and reverse dressing, and the adjusting wheel dressing seat can be adjusted according to the required angle of dressing. workpiece to ensure the accuracy of the workpiece cylinder.

11. Ensure the adjustment of the contact surface between the workpiece and the grinding wheel during grinding. Rotation angle range +5°~-5°.

12. The upper slide of the skateboard adopts a dovetail groove design. The knife advances quickly and precisely,

13. The bottom sliding plate adopts Λ-shaped sliding rails and double-shaped auxiliary rails. The double Λ-shaped sliding rails have been hardened by high-frequency ground and precisely to effectively prevent mud from entering. The micro-power device has a minimum feed quantity of 0.001mm, which can meet the needs of various parts.

14. The adjusting wheel is driven by Japanese Mitsubishi servo motor, with low speed and high torque, it is easy to operate and adjust.

15. The adjustment wheel housing is driven by a servo motor and driven by a worm gear, which can effectively eliminate the impact of ordinary motor vibration on precision machining and ensure stable precision.
