Diamond cutting wheel grinding characteristics

Diamond thin cutting wheel is mainly used for fine groove and cut close , generally deep creep feed grinding method . With grinding depth, feed rate is small, the grinding wheel and the workpiece contact area, narrow kerf , metal removal rate, grinding , high precision, good surface quality and material utilization characteristics. The polishing pads for granite  general rule is as follows:
1 ) Overall wheel cut thin ( more below 0.5mm ) , small diameter (20-100mm), fine particle size , size and shape and position precision , light weight , generally used in the high- speed conditions . Average speed of 5000-40000 rpm.
2 ) . Matrix-type cutting wheel mostly thick (0.5-2mm), diameter (100-200mm), coarse granularity , the accuracy is low, generally used for lower -speed large depth of cut conditions. Average speed of 3000-10000 rpm. 3 ) ultra-thin cutting wheel to use more fine-grained , and generally thinner grit size of its correspondingly thinner, good surface quality . However, the finer abrasive particle size decreased sharp cutting corresponding to correspondingly reduce the feed rate to accommodate the grit size machinability . 4 ) ultra-thin cutting wheel cutting depth is generally cut parts by the user according to fixed , the cutting mostly used creep feed grinding process , the depth of a cut to the . Such as thin cutting wheel , cutting conditions are poor ( mostly three face contact with the workpiece ) , making it difficult to heat , so to increase ( flow, pressure ) cooling the cutting area .
 5 ) When the cutting wheel at the customer 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 cut after Plate Compactor  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 performance mainly with thin cutting wheel for abrasive particle size , particle size finer surface finish processing the better . Simultaneously with the workpiece material , hardness, cutting the amount of machining conditions , processing requirements and other factors are also related.
7 ) Ultra-thin cutting wheel factory has been carried out before the general shaping and the blade , users can directly use . If you need further surgery, recommended green silicon carbide or corundum stone, cutting wheel size selected coarse granularity than 1-2 numbers ; if you  sds hammer drill bits need further used for a period after the blade or the blade , it is recommended to use green silicon carbide or corundum Whetstone, cutting wheel size selected fine granularity than 1-2 number or the same number can be.
8 ) general but also with cutting material to be processed , hardness, precision machining requirements related to the proposed initial use of the best in the user's original conditions, do not easily change cutting .
9 ) to the user condition is also a major factor affecting the cutting performance , especially in the spindle axis moving string , runout , the flange parallel, have directly affected balancing precision cutting wheel cutting precision .
