JiRun series CNC single column vertical lathe adopts modern advanced design concept, production process, assembly process and strict ISO9001 quality management system. Control system uses reliable German Siemens 802 c / 802 d control system, and driven by Siemens servo motor on ball screw rotation, carries out precision control according to the procedure. The structure of CNC vertical lathe is that main shafts layout vertically, worktable rotate in horizontal, vertical or oblique feeding of tool post. With convenient installation and debugging on workpiece, the workbench supports big weight, good rigidity and smooth cutting. This machine is mainly used for machining large and heavy-duty workpiece with large diameter and short length, such as coarse and fine machining processing of the inner and outer cylinder, end face, inner and outer conical surface, cylinder, cone hole, grooving, drilling, reaming, reaming on different kinds of disc, wheel and set workpiece etc.
