Valve Turning Automatic Large Double Column Heavy Duty VTL CNC Vertical Lathe

The double column vertical lathe is a cutting-edge piece of equipment that combines mechanical, electrical, and hydraulic components. It incorporates modern design principles and manufacturing techniques, leveraging CAD optimization and state-of-the-art components from both domestic and international sources. The machine boasts a robust structure, offering exceptional strength, high static and dynamic stiffness, precise machining capabilities, heavy load capacity, efficiency, durability, and reliable operation. All major technical specifications of the machine parts comply with national standards.

Worktable

Worktable has worktable base, worktable, spindle parts and transmission device. Worktable and worktable base are whole cast iron structure, adopting high strength low stress iron casting, which has enough rigidity, strength and heat stability. Worktable spindle bearing adopts high precision double row short cylindrical roller bearing. It could ensure the worktable high precision rotation and long service life.

Main transmission

The main transmission system of the machine is vertical shaft transmission. It adopts spindle AC servo motor to drive; gearbox achieves mechanical two gear transformation by the shift cylinder pushing the change gear, so that the worktable could do stepless speed regulation within 0.63-63r/min.

Gantry frame

It is composed of left and right vertical columns and connecting beam. Gantry and worktable base form the sealing structure. In the upper part of the gantry, there is left and right lifting box, driven by biaxial stretching AC motor. Through gear pair, worm and gear pair and double leadscrews make the beam to do lifting movement along the left and right column guide rail.

Beam

Beam adopts high strength and low stress iron casting with enough rigidity and strength, so as to ensure the machine accuracy to have long term retentivity and stability. Beam is in front of the vertical column, and it does the vertical movement along the vertical column guideway. On the back of beam, there are 4 hydraulic clamping points. On both sides of the beam, there are feeding box for tool rest.
