高速钢刀具的理想磨削工具是CBN (立方氮化硼)砂轮,在应用CBN 砂轮时必须解决其修整问题,这是目前各国努力开发的课题之一。现将日本的电解修整方法简介如下。修整原理见图1,1为被修整的CBN 砂轮,接正极,该砂轮CBN 粒度140/170。2为测量CBN 砂轮表面状态的涡电流计。3为电解修整工具,接负极。4为含有10% NaNO_3的电解液。5为直流电源,最大电流50A,电压为0—20V。修整时,砂轮和修整工具间以距离δ持合适间隙,二者分别驱动反向回转。电解修整
The ideal grinding tool for high-speed steel cutting tools is CBN (cubic boron nitride) grinding wheel. The application of CBN grinding wheel must solve its trimming problem, which is one of the most developed problems in various countries at present. Now Japan’s electrolytic dressing method is as follows. Trim principle shown in Figure 1,1 is a trimmed CBN wheel, connected to the anode, the wheel CBN particle size 140 / 170.2 to measure the surface condition of the CBN wheel eddy current meter. 3 for the electrolytic dressing tool, then negative. 4 is an electrolyte containing 10% NaNO 3. 5 for the DC power supply, the maximum current 50A, the voltage is 0-20V. Dressing, grinding wheel and dressing tools to maintain the gap between the gap δ, the two were driven reverse rotation. Electrolytic dressing
