5. Catching ball box:Catching ball box be used to receiving rolling steel ball on the plate, inside with the soft material.

Steel ball

Made of GCr15 bearing steel the accuracy of it is not lower than “0” level of regulation of GB 308-77 steel ball, it is the 33 kind steel ball which diameter is 1 inch, could be used as test steel ball.

The steel ball is name the ball number according to the 32 times according to the inch diameter. Should use a set of steel ball that it is continuous number

Steel ball should be stored in anti-rust oil. The rust and scars ball should change in time.

Cleaner and wipe the material

3.1 Eliminate lotion: lotion can be used appropriate solvent such as chemical pure acetone, ethyl acetate, ethanol etc.

3.2 Wipe the material:Use the soft fabrics such as absorbent gauze wipe as materials. This kind of material shall not contain substances soluble in the solvent.
