Precautions for Purchasing Polycrystalline Diamond Cutters

The most significant parts of polycrystalline diamond cutters are diamond, because the tool work is primarily diamond and object interaction for cutting or grinding. As a result, for the purchase of diamond cutters, i.e., diamond selection, the following to introduce for you to pay attention to the site where you buy diamond cutters.

1. Particle size selection for polycrystalline diamond cutters

Diamond particles are very coarse, and only a single particle when the saw blade tip is very sharp, sawing cutting efficiency is very high, but diamond caking resistance bending strength is reduced. Diamond particles are fine or coarse, fine, mixed when the saw blade tip can use very durable, but relative efficiency is low. Diamond particles are fine or coarse, fine, mixed when the saw blade tip can use very durable, but relative efficiency is low. Diamond particles are fine or coarse, fine, mixed when the saw blade tip can use very durable, but w hen the number of diamond particles is between 50 and 60, polycrystalline diamond cutters are preferred.

2. The selection density of polycrystalline diamond cutters

If the diamond distribution density changes from small to high, saw blade sharpness and sawing efficiency will gradually deteriorate, and the duration of use will gradually lengthen. The saw blade will become unsharp if the density is too high.

The efficiency will improve if the distribution density is lower and the grain size is coarser. When cutting through the saw using polycrystalline diamond cutters, each section of the cutter head has a different effect. The cutter head runs in the centre of a depression during the sawing process while employing varied densities, which helps to avoid saw blade deflection.

3. The selecting strength of polycrystalline diamond cutters

If the diamond's strength is too high, the crystal will be difficult to cut; if the diamond's strength is too low, the crystal will be easy to break after impact, making the tool's performance poor; if the diamond's strength is too low, the crystal will be difficult to cut; if the abrasive grain is used to polish, the sharpness will be reduced, making the tool's performance poor; if the diamond's strength is too low, the crystal will be difficult to bear As a result, polycrystalline diamond cutters prefer diamond strengths ranging from 13 to 140N.

Selection of diamond tools is important, but it's also important to consider the bonding phase and the diamond sintering process. Each aspect must consider the location, and the timing must constantly be considered.
