Test method
According to the special exemption of GR/T174211-1998
, place a horizontal diameter suction cup on it, and move it once to verify the horizontal setting reading. Through the OAC base plane, based on the assumption of a good level, the coordinate values ​​of each measured surface are calculated inversely. The error between the points on the plane and the base plane is the recommended value. This work can also be tested by other equivalent force methods. 5.4.3.2.2 Turn the disk to the indicating point on the operation board and the table surface, and move the indicating bottle on the stop board for inspection: the error is based on the maximum position of the indicating reading. The working environment is 110V. When there are special requirements, other standard voltage values ​​are also allowed. 4.3 Appearance
4.3.1 The magnetic poles should be arranged neatly and evenly, and the working surface should not have cracks, rust, holes, pits, burrs and other defects that affect the performance and appearance.
4.3.2 The maximum allowable value of the surface roughness R of the suction cup installation surface is 0.B, and the maximum allowable value of the surface roughness R of the suction cup table is 1.25
4.4 Structure
4.4.1 The lead-out wire of the sucker should have good sealing, absolutely resistant to boiling and recovery. Measures for breaking: 4.4.2 The lead-out wire connection should have good anti-falling measures 4.4.3 The heavy-duty sucker should have a lifting device.
