The base of the vertical lathe, the operating table, the plate bed, the load-bearing beam and other large objects are selected with high compressive strength, good wear resistance, gray cast iron and quenched to solve the problem, remove thermal stress and no deformation. There are two ways of vertical tool table, square ram and manual pentagonal tool table, and the side tool table is equipped with a square tool table, and both tool tables are balanced by hydraulic press. The spindle bearing transmission system of the CNC lathe is driven by the AC motor, and the speed regulation organization of the 16-level spindle bearing completes the scope of the speed ratio of the operating table.
Vertical lathes belong to large and medium-sized industrial equipment, which are used to produce and process large and medium-sized and super-heavy product workpieces with large axial specifications and small radial specifications, and complex appearances, such as a variety of discs, wheels and shaft parts to process the round surface, inner hole, conical surface, cylindrical hole, cone hole, etc., and can also rely on additional equipment to carry out production and processing of external threads, turning surfaces, profiling, cutting and cutting.
Compared with the horizontal lathe, the product workpiece is clamped in the clamp decoration design of the CNC lathe, and the center line of the spindle bearing of the CNC vertical lathe is vertically and reasonably arranged, and the counter surface of the operating table cabinet is in the horizontal plan, so the clamping and alignment of the product workpiece is more convenient. This kind of rational layout relieves the load of the spindle bearing and rolling bearing, so that the vertical lathe can maintain the precision of the work for a long time.
