Machine accuracy:
1. Spindle rotation accuracy:(1) radial runout of inner hole: 0.003mm;(2) axial runout of shaft end: 0.003mm;
2. Coaxiality of spindle at both ends: 0.01mm;
Typical parts machining accuracy:
After grinding the center holes at both ends of the shaft, after grinding the outer circle with the center hole positioning after grinding, the outer circle runout to the center hole shall be ≤ 0.005mm, the surface roughness of the center hole shall be Ra1.6, and the cone angle of the center hole shall be 60 ° ± 0.5 °.
Main structural features:
1. The bed guide rail adopts linear guide rail with stable precision and performance.
2. The movement of the grinding device is realized by the ball screw driven by the servo motor, and the efficiency and accuracy are more reliable.
3. The grinding tool is installed on the mechanical spindle, driven by the motor to rotate, and the workpiece is fixed. The motors at both ends can be controlled separately according to the different diameters of the center holes at both ends, and the speeds are different with different diameters, so as to achieve the consistency of the accuracy of the center holes with different diameters. The grinding efficiency is high-performance and stable.
4. The cooling of the grinding part is realized by semi-dry oil and gas lubrication, which has compact structure, low energy consumption, and the machine tool is more tidy.
5. The movement of the grinding device adopts PLC servo automatic control, and the replacement of different varieties of parts only needs to adjust the parameters.
6. When grinding, the servo motor realizes automatic feeding and lapping according to the set torque, with high efficiency and reliable precision.
7. The workpiece is fixed, the grinding tool rotates at both ends, and the rotation speed and direction can be controlled separately, which can make the center holes of different diameters reach the same accuracy at the same time.
