Characteristics, Applications, and Grinding Methods of Grinding Platforms

Name: Grinding Platform

Material: Cast iron HT200-300 with a working face hardness of HB170-240. After two manual treatments (manual annealing at 600-700 degrees and natural aging for 2-3 years), the grinding platform has a form of sanding on a flat plate embedded with diamond abrasive during grinding processing. In this form, the grinding tool is the main tool, which is called the embedded sand grinding flat plate Grinding plates have uniform organization, dense structure, no defects such as sand holes, pores, and looseness Easy to sand, evenly distributed and abundant sand particles, firmly embedded and cut The surface is smooth, shiny, and sky blue in color, good

Usage: Grinding technology is used for the production of work surfaces, repair of measuring tools, and the surface roughness Ra of the parts after grinding with this product is ≤ 0.08 μ m.

Accuracy level: According to the standard metrological verification regulations, there are four levels: 0, 1, 2, and 3.

Characteristics of grinding platform:

1. Simple operation, fast sanding, sufficient sand embedding, easy to apply the same type of sand after use. After polishing, the smoothness is significantly improved

2. It is easy to measure the required high smoothness and adhesion of the block, and the workpiece mirror surface is shiny green

3. The flat cutting still has good cutting performance even after mild sand guidance, and feels smooth during grinding

Grinding method

One method is the three plate mutual grinding method, which refers to the sequential mutual grinding of three flat plates, and each cast iron flat plate is used as the lower plate twice, with a total of 6 times of grinding in practice. The result of grinding and sanding with this method is that the flatness of the three flat plates is very good, and the sanding effect of the three flat plates is basically the same. All three flat plates can be used without frequent sanding.

Another method is the mutual grinding method of two plates, also known as the mother plate pressing method. This method only uses two cast iron flat plates to grind each other up and down.

The result of grinding and sanding with this method is that the flatness of the two flat plates is basically consistent, with the flatness of the upper plate being concave and the flatness of the lower plate being convex, and the sanding effect of the lower plate is better than that of the upper plate.

. Due to the concave middle of the upper plate, it is not easy to repair the measuring block. Generally, the upper plate is not needed, only the lower plate is used as a flat plate.
