abrasive belt grinding characteristics


Accumulation of abrasive belt in recent years, the emergence of a new type of grinding tool with high grinding efficiency, grinding, stable performance, precision grinding and long service life, etc., so they can meet a variety of high-density material and metal abrasive paper sheet  alloy grinding and polishing, precision grinding is the tool of choice.
Second, the accumulation of abrasive belt grinding characteristics
1, the special grain structure
Stacking abrasive belt from the exterior is constituted by a series of coarse grains, and virtually every large number of fine grains are made of alumina or silicon carbide abrasive material, the abrasive particles through high-strength adhesive firmly attached to the substrate, and the fine abrasive particles are randomly arranged, so that the whole process Mounted flap wheel  of grinding particles are worn little by little, a random residual sand off, exposing new abrasive continue to complete work, a multilayer improved abrasive grinding belt service life, this multi-level continuous grinding operation method greatly superior to conventional electrostatic planting plant sand sand or gravity, etc., distributed on the abrasive surface of the substrate layer to form a unified arrangement of sand surface to to achieve the purpose of grinding.
 2, a new concept of self-sharpening
Stacking abrasive belt is composed of many fine powders accurate dimensions, by making bonded together to form a large need for abrasive particles, and then through the sand advanced electrostatic planting technology, the abrasive evenly "planted" in the specially treated substrate The refining of a high-strength belt, which can be like abrasive as in the grinding process blunt abrasive action of the centrifugal force continuously off, thereby exposing the new sand, which can stably be workers.
 3,1-3 times lifetime
Stacking the abrasive abrasive belt polymerization, so that the abrasive grinding unit area more participants, thus extending the  Sanding Sheets service life. General stacked abrasive belt life is 1-3 times of ordinary belt. Belt long life, thus reducing the number of frequent replacement belt sander and adjustment, saving time, but also to avoid fluctuations in the quality of workpiece, improve processing efficiency and quality of the workpiece to ensure product quality stability, reliability.
4, good quality grinding
And accumulation of abrasive belt abrasive belt grinding effect comparison, we see that accumulation of abrasive products abrasive grinding surface roughness of the workpiece with the grinding time, after relatively stable. While ordinary abrasive products grinding the workpiece surface roughness of the front varied. This shows that the accumulation of abrasive belt, grinding surface effect is more stable, better consistency.
5, low grinding heat
Moment of grinding temperature and concentrated in the surface layer of a local area, the surface will cause local changes in microstructure, form grinding burn. Burn-in phenomenon will cause decreased mechanical properties of the surface, reducing the hardness of the workpiece and durability, reduce the life of the workpiece. Of abrasive belt, with the grinding time, the abrasive grains continue to be blunt, and can not self-sharpening, grinding and thus the state changes gradually sliding friction of the cutting condition, resulting in grinding zone temperature rise, resulting in surface burns ; The accumulation abrasive belt, abrasive due to the accumulation of multilayer effects in the grinding process will continue to fall off, exposing new sharp sand, so that the entire process is cutting the state, to avoid generating excessive surface grinding heat while shedding abrasive, but also take away a lot of grinding heat and chips, to ensure the quality of the workpiece surface.
