Limit high-speed grinding processing efficiency theory model
c intensity this time constraint wheel well satisfied. High Efficiency Deep Grinding of single particle is exposed to the impact of cutting force in Figure 3 and other high efficiency ultra-high speed grinding wheel grinding ratio of Shandong Institute of Light Industry of the first grinding method l4 roughly equal volume, will not increase the CBN abrasive This makes the probability of broken single plated CBN grinding wheel than a large margin. Figure 3 shows, in addition to the same amount of metal grinding materials, 330m / s when the radius of grinding wheel wear than 140m / s reduced by 26% when the grinding wheel will increase about 2 times than that. Here's the wheel of Chip constraints determine the efficiency of the extreme high efficiency deep grinding. Basic conditions,[link widoczny dla zalogowanych], electroplating CBN grinding wheel, diameter 400mm,[link widoczny dla zalogowanych], grinding wheel peripheral speed 180m / s, workpiece material 18CrMn by the type g4) to take chip space efficient than the worthy of the highest efficiency and the theoretical value of the Q5l = 1880rI Ⅱ n / ram · S (100 #) ; Q252 = 31370ITaTI3/ram · S (60 #). The results shown in Figure 4, after cutting class for the 6into, the fine grinding mill pay attention Koo (canthal / n \1500mm/mm · s or so,[link widoczny dla zalogowanych], the radial force increases rapidly, indicating that the grinding wheel chip space has reached saturation,[link widoczny dla zalogowanych], wheel removal rate close to the limit. with coarse grit grinding wheel may be further increased removal rate, depth of cut of 10mm in the removal rate When reached 3000mm3/ram · s rapid rise in grinding force, grinding wheel chip space is saturated with better test results than the above theoretical analysis. 3 Conclusion 3.1 The efficiency of ultra-high speed grinding wheel by the strength of the wheel Yung-chip, motor driven power and integrity of the workpiece 3.2 The proposed high efficiency under multiple constraints limit the efficiency of the grinding model agree well with the test results.
