3、主軸采用P5級軸承,并經精密動平衡,軸承采用進口潤滑脂潤滑,確保主軸高速平穩旋轉,并將熱變形降至低限度。
1. The machine tool adopts the trinity of machine, electricity and liquid, and is designed according to the pleasant layout of ergonomics, with compact structure, saving area, simple operation and convenient maintenance.
2. The bed guide rail adopts rectangular guide rail structure. After high-frequency quenching, the contact surface with its corresponding sliding plate is plastic coated guide rail, which can significantly reduce the friction resistance when the guide rail slides, and has good dynamic characteristics.
3. The main shaft adopts P5 grade bearing and is subject to precision dynamic balance. The bearing is lubricated with permanent imported grease to ensure the stable rotation of the main shaft at high speed and minimize thermal deformation.
4. The vertical and horizontal movements of the machine tool are directly connected with the lead screw and AC servo motor, and the lead screw bearing adopts angular contact bearing to ensure the high precision of transmission. The clamping and positioning of the tailstock is realized by two screws on the side driving the clamping block. Lock the nut on the twin screw, and the screw drives the clamping block to rise to fix the tailstock on the bed.
