The last standard depth of control rail rust removal, when pressure is set when 0.1 millimeter of depth is eliminated rust, constant pressure can be protected
, all in 0.1 millimeter, error is within 0.02 for all of depth of the whole rust cleaning scope of card.Smoothly pressure can just make to remove
The surface of rust is uniform and smooth, highly polished.If pressure transient, fluctuation is produced, has resulted in the wave vestige on rust cleaning surface,
It is possible to this rust cleaning standard or rust cleaning surface more than 0.2 millimeter not eliminate rust clean completely and produce black speck vestige, exceedes
0.2 millimeter of this standard destroys the original rigidity of rail and hardness it is determined that damage rail.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to the above
The change of embodiment, modification will all fall in Claims scope of the present utility model.
