目前,CBN砂轮的使用量不断增加,但在日本却很少用它来磨削刀具,主要原因是工具磨床的刚性较低.难以发挥其特有的性能。Tool & Production 1982年2月号刊出《用CBN砂轮磨削滚刀的效果》一文,兹将其中的有关数据摘出,以供参考。所用磨床为西德Kapp公司的A5305T滚刀磨床,磨削液为Garia—T,用四个喷咀以35～40gPm的流量直接供给砂轮和工件,以防止出现热损伤。试验结果表明,最适合的砂轮是直径为8时、采用树脂结合剂的CBN Ⅱ型砂轮。砂轮上有一层金属涂层.导热性能良好。粒度为150~#,结合度为100,CBN磨料层厚度为1/16时,
At present, CBN grinding wheel usage is increasing, but rarely used in Japan to grind the tool, mainly due to the lower rigidity of the tool grinder hard to play its unique performance. Tool & Production 1982 February issue of “grinding hob with CBN grinding wheel effect” article, it will be the relevant data extracted for reference. The grinder used is the A5305T Hobbed Grinder from West Germany Kapp and the grinding fluid is Garia-T. The four nozzles feed the grinding wheel and workpiece directly at a flow rate of 35-40 gpm to prevent thermal damage. Test results show that the most suitable wheel is a diameter of 8, the resin bond CBN Ⅱ type wheel. Grinding wheel with a layer of metal coating. Thermal conductivity is good. Particle size of 150 ~ #, the degree of binding of 100, CBN abrasive layer thickness of 1/16,
