The difference between scraping and grinding platforms

Many customers are unsure whether they want a cast iron grinding platform or a cast iron scraping platform when purchasing a cast iron platform, and even spend money on the grinding platform. So let me introduce the differences between these two platforms to you!

The difference in appearance between scraping and grinding platforms

The difference in appearance between scraping and grinding platforms

The working surface of the scraping and grinding platform has knife marks and patterns, while the grinding platform has a smooth surface, oil content, and a sky blue color due to a machine grinding process. There are no knife patterns on the working surface.

Price difference between scraping and grinding platforms

Due to the addition of technology to the grinding platform, the quotation is much higher than that on the scraping platform cabinet. We remind our customers and friends that when choosing a grinding platform, they should make more comparisons and choose a reputable manufacturer to avoid being deceived.

How to choose grinding platform and scraping platform

A grinding platform with good flatness and surface roughness should be selected. The gap between any two of the three grinding platforms should be less than 1/2 of the required diamond strength size. Therefore, before grinding, a 0-level knife edge ruler should be used to measure the flatness of each flat plate (white light flatness is greater than or equal to 2.5 microns, red light flatness is 1-2 microns, blue light flatness is 0.5-1 micron, and opaque flatness is less than or equal to 0.5 microns).

The difference in accuracy between scraping and grinding platforms

Grinding platform is better than scraping platform. The scraper marks on the platform surface are submerged and the flatness difference is small.

The use of grinding platform eye masks and inspection by departments such as optics. Grinding plates have uniform organization,

The structure is dense, without defects such as sand holes, pores, and looseness. It is easy to sand, and the distribution of gravel is uniform, rich, and abundant. The gravel is firmly embedded and cut.
