Select the grinding wheel and the guide wheel. The choice of grinding wheel and guide wheel mainly refers to the size and characteristics of the [url= ]high quality cutting disc supplier[url]. The diameter of the grinding wheel and the guide wheel is mainly determined by the machine model. For example https://www.cheapshoesonlineaustralia.com/ , the M1080 centerless grinding machine has a grinding wheel diameter of 500 mm and a guide wheel diameter of 300 mm. The width of the grinding wheel and the guide wheel is determined by the machine tool when the penetrating method is used. On the M1080 type centerless grinding machine, the width of the grinding wheel is 150 mm and the width of the guide wheel is 150 mm. When grinding by the cutting method, the width of the grinding wheel and the guide wheel should generally be 5 to 10 mm larger than the length of the workpiece to be ground. If the workpiece is stepped, the width of the guide wheel should be chosen according to the length of the longest outer circle on the workpiece. That is to say, it is sufficient in the work that the guide wheel is in contact with the outermost surface of the workpiece. If the surface is ground wholesale nike shoes australia , the width of the guide wheel can be narrower, but not less than 25 mm. The characteristics of the grinding wheel are mainly selected according to the processing materials and processing requirements. The selection principle is the same as the selection of the general cutting disc. The grinding wheel is generally made of corundum cutting disc made of the ceramic bond. The guide wheel is made of corundum cutting disc made of rubber bonding agent. However, when grinding tough metal (such as cast iron or non-ferrous metal), the grinding wheel is black. Silicon carbide cutting disc. Grinding wheel particle size is generally selected from 60 to 80, the guide wheel particle size is generally selected 80 wholesale shoes australia , the hardness is K ~ L. Trim the cutting disc and the guide wheel. In rough grinding, the cutting speed of the cutting disc is fast to obtain a sharp cutting edge; when finishing grinding, the cutting speed of the cutting disc should be slow to obtain the contour and micro-blade of the cutting disc. The guide wheels must be trimmed at high speeds. There must be enough coolant in the two rounds of trimming. Select the workpiece pallet. According to the calculation results, select the appropriate pallet and adjust the center height of the workpiece. When adjusting the front and rear guides, take a test rod with the same diameter as the workpiece wholesale sneakers australia , place it in the grinding area, and slowly shake the feed handwheel so that the test stick can be gently touched by the cutting disc and the guide wheel. Rotate or move the ground, then install and adjust the guide according to the requirements of the guide adjustment. Trial the workpiece. First, start the cutting disc, and then adjust the speed of the guide wheel. After the cutting disc and the guide wheel are in normal operation cheap nike shoes australia , open a little coolant, place the workpiece on the pallet, push the workpiece into the grinding area a little, and gradually feed the handwheel until The workpiece begins to rotate and produces a slight spark. Observe the sparks. Carefully observe the spark distribution in the grinding zone. For example, there are sparks in the entire grinding area cheap sneakers online australia , and concentrated in the front 23 of the grinding area, gradually decreasing until disappearing, and the workpiece movement is stable, indicating that the selected parameters are reasonable, otherwise it will be re-adjusted.
