The Scraping Plate

The Scraping Plate
The scraping plate is also called the scraping platform and it is made by the GB/4986-85 standard with the grinding process on its working surface.The scraping plate /the scraping platform served for the parts grinding and the measuring tool repair.The parts which have been grinded by the scraping plate/the scraping platform would be a bit smaller on the size and weight,the roughness of its surface Ra≦0.08μm and the specification is limited at 100×100--800×600.

The scraping plate is also called the scraping platform and it is made by the GB/4986-85 standard with the grinding process on its working surface.The scraping plate /the scraping platform served as the grinding for the parts and the measuring tool repair.The parts which have been grinded by the scraping plate/the scraping platform would be a bit smaller on the size and weight,the roughness of its surface Ra≦0.08μm and the specification is limited at 100×100--800×600.
Generally speaking,in the grinding process,the scraping plate/the scraping platform usually adopts the way of dull polish which is working on the embedded carborundum grinding material plate.And there is a main and necessary grinding tool which is called the embedded sanding plate in this working mode.It is mainly used in the making or repairing of the measuring tools,the grinding of the spare parts,the making of the high-precision machinery parts and the process of the optical instruments.
The Scraping Platform Features:
Easy to operate,fast to supply the sand and abundant to the embedded sand quantity,it would be still convenient to supply the same type of sand after using.And the smooth finish would be improved greatly after polishing.
Easy to get a higher smooth finish and the lapping-in property which might be needed to the gauge block and make the mirror surface of the spare parts to be clean and crystal.
Endurable to use and persistent and all-round to the cutting and it would still remain a fine cutting property after the mild sand leading,you will feel free when you try to push it in the daily work.
