the lt series is a series of cnc machine tools with high precision, high rigidity and high cost performance. it has the characteristics of rapid traverse speed, high chip parameters, constant surface speed, etc., and each axis has a safety clutch and can choose rear or side row according to the layout of the workshop. chip conveying device, the machine tool is assembled by a special team composed of professional and skilled technology under the guidance of expert technology.
•servo motors all use alpha motors
•the system adopts japanese original fanuc frank, 10.4-inch led color screen, multi-language display.
• two axes with 15m/min rapid traverse, powered chuck or standard gripper system.
•hollow spindle. the spindle is assembled and tested in a controlled clean environment. the front and rear ends are combined with high-precision cylindrical roller bearings and bidirectional angular contact thrust ball bearings to ensure high axial and radial stability of the spindle. with grease lubrication, the spindle motor adopts a high torque motor to ensure high chip power.
• hydraulic tailstock, programmable, the tailstock is supported by a v-rail and a flat rail.
