High Speed CNC Vertical Lathe Machine SCVT-280/2R

1. This series of machine tools is used for carbide and ceramic cutting tools, and is used for rough and fine turning of inner and outer cylindrical surfaces, inner and outer conical surfaces, end surfaces, grooving and boring, and rotary surfaces of ferrous metals and some non-metallic parts.

2. The main transmission of the machine tool is driven by a DC motor, and the speed range of the workbench is realized through a two-speed spindle speed change mechanism.

3. The machine tool is a frame structure composed of left and right columns, connecting beams, crossbeams, working bases and other components. The structure is rigid and has a large load-bearing capacity. The crossbeam clamping mechanism is a multi-station hydraulic locking device, and its operation is stable and reliable.

4. The feed tool holder of the machine tool adopts a CNC single tool holder structure. The machine tool tool holder slide horizontal movement X axis and the ram vertical movement Z axis are both driven by servo motors, and the ball screw is driven by a high-precision fixed ratio gear pair to realize tool holder feeding and rapid movement.

5. The workbench is a thermally symmetrical structure. The worktable spindle uses high-precision adjustable radial clearance double-row short cylindrical roller bearings for centering. The shaft uses constant-flow hydrostatic guide rails and is equipped with an oil temperature cooling device, which makes the worktable have the characteristics of high rotation accuracy, large load-bearing capacity, and small thermal deformation.

6. The horizontal guide rails of the vertical tool holder include hydrostatic unloading guide rails, rolling and sliding composite guide rails, and sliding guide rails. The vertical movement of the ram is a sliding guide rail.
