Ultra-thin cutting wheels grinding characteristics and Precautions

Ultra-thin cutting wheel is mainly used for fine grooves and cut close , generally use deep creep feed grinding method. With grinding depth, feed small speed, large contact area of the grinding wheel and the workpiece , narrow kerf , metal removal rate, high grinding precision, good surface quality and material utilization characteristics. The  ore bits for concrete general rule is as follows : 1 ) the overall thickness of the thin -cut piece wheel ( mostly in 0.5mm or less ) , small diameter (20-100mm), fine granularity, high dimensional and geometric precision, light weight , general conditions in the high- speed next use . Average speed of 5000-40000 rpm. 2 ) . Cutting wheel base body mostly thick (0.5-2mm), diameter (100-200mm), coarse granularity , low accuracy , generally used for low speed large depth of cut conditions. Average speed of 3000-10000 rpm. 3 ) ultra-thin cutting wheel to use more fine-grained , and generally having a thickness thinner abrasive particle size accordingly thinning, good surface quality . However, the finer the particle size of the abrasive cutting sharpness drop corresponding to  diamond bandsaw blades the feed rate is reduced accordingly to adapt the particle size of the abrasive machinability 4 ) . Thin cutting wheel cutting depth generally by the user to set the cutting element , the cutting mostly using creep feed grinding process , the depth of a cut to the . As the cutting wheel so thin, poor cutting conditions ( more than 3 face contact with the workpiece ) , making it difficult to heat , and therefore to increase ( flow, pressure ) cooling the cutting area. 5 ) When the cutting wheel at the user has just appeared on the machine does not move or cut the workpiece chipping , the proposal to increase the cutting speed or decrease feed rate ; When the cut after a period of time does not move or chipping , it is recommended to use Whetstone appropriate granularity on the surface of the blade wheel to adjust its sharpness . 6 ) . Workpiece surface quality and cutting and thin cutting wheel performance is mainly related to abrasive particle size , particle size finer surface finish  masonry drill bits processing the better . Simultaneously with the workpiece material , hardness, cutting consumption , machine condition , processing requirements and other factors are also related. General before 7 ) thin cutting wheel and the factory has been shaping the blade , users can directly use . If you need further surgery, recommended green silicon carbide or corundum white stone, grain size selected coarse granularity than the cutting wheel , No. 1-2 ; If the user needs to further open the blade edge , or use some suggested green silicon carbide or corundum white Whetstone , particle size selected fine grain size than the cutting wheel or 1-2 numbers to the same number . 8 ) Cutting general but also with the material to be processed , hardness, precision machining requirements related to initial use is recommended to use the best in the user's original condition , do not easily change cutting parameters . 9 ) user conditions also affect major factor cutting performance , especially in machine tool spindle axial vibration , runout, parallelism directly affects the flanges , etc. cutting wheel balancing precision cutting accuracy.
