Gear head lathe Metal lathe machine for VCT1400 Turning mental lathe
Product introduction and use
This machine is an automatic CNC machining machine for machining the inner and outer cylindrical surfaces of the parts, conical surface, end surface, grooving and chamfering. It is especially suitable for brake hubs, drums, clutch pressure plates and flywheels. Processing of parts such as shells.
Main structural features
- The machine tool is a single-column vertical guide rail structure. The column, base and sliding seat are all made of high-grade gray cast iron resin sand casting process and aging treatment; reasonable structural design, perfect processing and assembly process to ensure long-term use of machine tools. Stability and accuracy retention.
2.The machine tool spindle adopts wide-area and high-torque servo motor drive, which can be used for low-speed and high-torque, heavy-duty cutting, and high-speed cutting. At the same time meet the needs of roughing and finishing.
- The machine tool spindle adopts high-precision double-row cylindrical roller bearing and bidirectional thrust angular contact ball bearing and double row cylindrical roller bearing configuration. The configuration structure has the largest bearing capacity, can withstand large cutting force and feed force, has high radial stiffness and axial rigidity, and has high rotation precision.
- The X and Z-axis servo motors directly drive the precision ball screw pair through the flexible coupling, which can minimize the backlash and have high positioning accuracy. The Z-axis lifting configuration balances the weights, the structure is simple and reliable, and the failure rate is low.
The X and Z axes are made of domestic precision ball screw pair and ball screw special bearings, which meet the requirements of high rigidity and high precision cutting. The pre-stretching structure of the screw support greatly reduces the influence of thermal deformation on the accuracy of the machine during long-term operation.
- The X and Z axes adopt advanced centralized automatic lubrication device, timed automatic intermittent lubrication, and the work is stable and reliable.
- The machine tool holder adopts the EPT knife holder or the row knife form, with accurate accuracy and high efficiency.
- This machine can be equipped with CNC systems such as ZheJiang Kai Endi, FANUC and other famous brands at home and abroad according to user needs.
