Talking about the development and status of cut pieces

Speed ​​the development of resin abrasive relatively fast, whether it is growing year by year from the product in production, quality and variety, especially in recent years has become a booming good situation. Why resin bonded abrasives will develop so fast, in addition to objective conditions, such as social requirements Sik, there is sufficient raw materials ...... and so on. The most fundamental reason is that the resin binder and has unique properties inseparable. To talk about its advantages: first, it  cutting and grinding disc combines high strength. Comparison with other binders, resins have a higher bond strength at higher speeds can be used to withstand greater pressure grinding, which is widely used in rough grinding and deburring process in the steel and foundry industries. And with the improvement of the grinding process, the grinding of the cutting disc load and strength requirements are also rising, from the past hanging portable grinders and sanders to today's high-speed heavy-duty billet repair mill, cutting pieces from the past use of the speed of 35-40 m / s, developed to 80-100 m / sec, the wheel loads from the past 30-50 kg, to today's 1,000 kg or more, if No high strength bond is difficult to achieve.
 Followed by the abrasive can be  velcro disc made special shapes and special needs. This is mainly due to the binder resin at a low temperature (200 ℃ or less) hardening conditions do not change the basic properties of the material, which can be added to the different needs of the filler material embedded or ornament. In order to meet requirements such as grinding grooves and can be made with porous shaped grinding wheel, grinding wheel in order to improve the strength of the glass can be added gingham and other metal wire mesh in cutting tablets. Can be added to increase the conductivity of copper, aluminum and graphite powder. Third, suitable for manufacturing thin wheel throughout the specification. In many metal cutting and slotting processing sector has been widely used processes, to achieve the thinnest 0.1 mm, which completes the blade can not be done in general processing tasks, especially in high speed after the cutting reinforcing sheet has been widely metal cutting wheel  used, the need for the cutting wheel increased rapidly.
Fourth, the binder resin has a certain elasticity. In the grinding process, the surface roughness is conducive to meet the higher demand. In the machining process, grinding and polishing processes more choice of resin bonded grinding wheels, grinding under the same conditions, the resin abrasive finish higher than ceramic abrasive.
