从80年代以来,我们使用全齿型电镀金刚石滚轮来修整全齿型砂轮,用来铲磨某发动机Ⅰ级Ⅱ级涡轮盘榫齿拉刀。它具有精度高、圆角R转接十分圆滑、修整时间短、操作方便、机床主轴精度不易损坏、使用寿命长等优点。原工艺是单齿钢挤轮修整砂轮,单齿铲磨榫齿拉刀,生产效率低、精度差,圆角R转接不圆滑,易损坏机床主轴精度。我们最近试验成功的用全齿型电镀金刚石滚轮修整的砂轮铲磨榫齿拉刀,这一新工艺,为我公司成型磨削找到了新途径,加工效果达到了国内先进水平。滚轮规格:φ100×φ40×22。机床:捷克斯洛伐克平磨装上单臂驱动装置。金刚石型号:JRⅢ型。金刚石粒度:70～80目。制造方法:内型面电镀。可达到技术精度:齿距:+0.005 -0.001mm;角度:在2毫米长度上±5’;圆角R:最小0.1mm 技术经济效果(与单齿钢挤轮修整比较): 1、提高修整效率3倍。2、拉刀寿命提高2倍。3、质量稳定,免去拉刀铲磨返修工序,并可提高机床利用率。4、减轻机床主轴负荷,延长机床使用寿命。5、技术等级较低的工人也能操作。
Since the 1980s, we have used all-toothed electroplated diamond wheels to trim the all-toothed grinding wheel to shred a class I II turbine disc tenon broach. It has high precision, rounded R transfer is very smooth, trimming time is short, easy to operate, the spindle precision is not easy to damage, long service life and so on. The original technology is single tooth steel wheel dressing wheel, single tooth shovel grinding tenon gear broach, production efficiency is low, the accuracy is poor, rounded R transfer is not smooth, easy to damage the machine tool spindle accuracy. We recently successfully tested with the whole teeth electroplated diamond wheel dressing grindstone grindstone tenon broach, this new technology for our company found a new way of grinding, the processing effect has reached the advanced domestic level. Wheel specifications: φ100 × φ40 × 22. Machine tools: Czechoslovakia Flat grinding with single-arm drive. Diamond Model: JR Ⅲ type. Diamond particle size: 70 ~ 80 mesh. Manufacturing methods: the inner surface plating. Can achieve technical accuracy: Pitch: +0.005 -0.001mm; Angle: 2mm in length on the 5 ’; rounded R: 0.1mm minimum technical and economic effects (with single-tooth steel wheel dressing comparison): 1, 3 times more efficient 2, broach life increased by 2 times. 3, stable quality, remove the broach shovel repair process, and can improve machine utilization. 4, reduce the spindle load, extend the service life of the machine. 5, the lower the technical level of workers can operate.
