Rolling screw assembly:

1. Bearing preloading: the bearing can be used as a pair of preloading bearings self-matching, the preload is about 0.020.05.

2. The wire assembly shall ensure that the bearing bracket motor bracket are equal in height the height at both ends shall be less than 0.01 mm 20 mm the shaft end.

3. In the two-dimensional (horizontal vertical) direction with the line track, the wire rod should also be strictly parallel, the overall non parallelism should be less than 0.01/300.

4. The beam, connecting plate z-axis slide plate should be installed first, the x-direction Z-direction guide rails should be perpendicular to each other.

5. When fastening the coupler of Yiming graphite engraving milling machine, uniform force should be applied one by one to ensure that the four phases are equal. After each component is assembled, the torque shall be weighed - the full range torque shall be less than 0.6 kg-m.

6. The manufacturer of preschool CNC engraving milling machine shall ensure that the pre installation inspection is carried out between the wire the nut between the wire the slider.
