The dicing sheet is made of abrasive and binder resin for cutting ordinary steel, stainless steel metal, and non-metal sheets, and the flat cutting disc on sale is classified according to the thickness of the dicing sheet. There are two kinds of curing methods for ultra-thin cutting sheets: thermosetting resin and photo-curing resin. Today, Shandong cutting chip manufacturers will take a look at these two curing resin methods. 1. Thermal curing resin method Generally, a thermosetting phenolic resin is used as a binder, and the diamond abrasive grains are mixed with a resin, and then sintered by hot pressing, and then heat-cured and then subjected to grinding processing. This process takes several hours, so the production cost is relatively high. 2, light curing resin It is a photocrosslinkable polymer, an initiator and an additive. It differs from the thermosetting resin in its essential nature in that the curing process is a chemical reaction caused by absorption of light radiation of a corresponding wavelength to convert the photocurable resin from a liquid to a solid. The conversion from liquid to solid is the result of an increase in molecular weight, rather than the evaporation of the solvent, so it has the advantages of rapid solidification, no pollution, and energy saving, but the constraint factor is the high price of raw materials. In the manufacture of standard cut off wheel for metal by photocuring resin method, China has successfully developed ultra-thin diamond cutting wheels with a thickness of 0.15mm by using photocurable resin as a bonding agent and successfully completed the cutting test of single crystal silicon wafers. At present, with the advancement of technology, photocuring has gradually begun to replace thermal curing. It can also be seen from the above that the photocurable resin method has many advantages over the thermosetting resin method, which is why it gradually replaces the thermosetting resin method.
