CNC Vertical Lathe
GV-760/GV-800
- The high-rigidity bed and wide-back fixed column make the machine tool extremely rigid and stable.
- The three-rail design of two guide rails hanging on the back wall and one side of the column and one upper support has the best guide rail bearing capacity.
- It adopts a two-level chuck pressure mechanism to automatically adjust the roughing and finishing clamping force, effectively reducing the deformation of the workpiece.
- High-quality resin sand castings, honeycomb structure, and secondary aging treatment to remove internal stress and reduce deformation.
- Use a precision grinding grade ball screw pair, in which the ball screw installation is a pre-stretched structure, which improves rigidity while reducing the impact of the machine tool’s cold and hot machines on the processing accuracy of the workpiece.
- The lubrication system uses a volumetric distributor and an intermittent lubrication pump to refill oil to regularly and quantitatively supply the oil required for the screw rod and guide rail to ensure that each lubricating part can be fully lubricated and reduce the waste of lubricating oil to avoid environmental pollution.
