Diamond grinding disc is a grinding disc tool made of diamond as the main material and adding other composite materials. It can also be called diamond soft grinding disc. It has fast polishing speed and strong grinding ability. The thickness of diamond grinding disc can also be said to be diamond grinding. The particle size of the tablets is different, and the grinding tablets of different specifications are divided into thickness and size.
The thickness of diamond grinding pads
1. Mesh distinction
The size of the abrasive particles is called particle size. The particle size is divided into coarse particle size and fine particle size. The particle size classification generally adopts the sieving method. For example, the particles that can pass through the sieve with 60 holes are called small particles, that is, the fine particle size, and the particles that can pass through the sieve with 40 holes are called large particles, which is Coarse-grained. Sometimes it is divided into medium particle size, and some are called micropowder.
The “thickness (granularity)” of the grinding head is identified by different color circles. The particle size is “medium”, and the grit number is 170 mesh, which is the first grade with relatively high acceptance and is suitable for a wide range of people; when it comes to grit degree, the larger the mesh number, the more the number of holes per unit screen, and the finer the particles. .
2. Grinding strength
The particle size of the grinding wheel has a significant impact on the surface finish and processing efficiency of the workpiece. For the cutting of high-quality alloy (tungsten steel) grinding head, the diamond grinding head works on the principle of “grinding”, and the grinding force generated comes from the shiny “diamond coating” on the surface. Although the larger the particle size, the rougher the hand feel and the greater the grinding force, but too much will be counterproductive. The finer the abrasive grains, the more uniform the grinding, and the smoother the surface of the machined workpiece, but the cutting amount is not so large, so the grinding efficiency is relatively low.
Choice of diamond grinding discs
1. Appearance observation
From the appearance, the whole should be uniform and there should be no cracks. This is a basic requirement. At the same time, it is necessary to check whether there are anti-counterfeiting barcodes and qualification certificates, so that the correct product can be selected.
2. Density weight
The density of diamond cutting discs is different, you should choose according to your own standards. In addition, the heavier the weight, the thicker the cutting disc, and the thicker it is, the more stable it will be in use.
The above is the introduction of how to distinguish the thickness of diamond grinding discs and how to choose a suitable grinding disc. Do you understand it?
