How many identification items of surface plates include?

There are five identification items together about the surface plates: the appearance and surface quality, roughness of working surface and sides, included angle of sides, contact point of scraping surface plates and the flatness of working surface.

How to protect the cast iron surface plates from deformation?

In case of any deformation happen during the processing of lifting, must be sure the four wire ropes which steadily hoist the four sides of surface plate in same-length.

When installing, the cast iron adjustable mounts on every supporting pointes should be well adjusted in order to bear averaged force. Our professional specialists are in charge of debugging the surface plates until getting qualified precision grade.

When using, please put down carefully and it is not allowed to move the rough workpieces on surface plates in case of any scratched, dented in places.

After using, please take down the workpieces in case that any deformation happens. When not in use, we need to clean the working surface, coat rust-proof oils, cover with rust-proof paper and package the surface plates with outer packing in order to protect the surface plates in well condition.
