从分析国内外现有工具存在的问题入手 ,着重解决超硬材料精密小深孔珩磨加工中走偏量较大、圆度误差较大等问题 ,提出了一种三导向的BTA型珩磨工具结构 ,使超硬材料精密小深孔加工的质量得到了提高 .实验证明 ,采用新型珩磨工具加工出的小深孔可达到走偏量 0 .0 0 1～ 0 .0 0 2mm/1 0 0mm ,锥度 0 .0 0 5mm/1 0 0mm ,圆度误差 0 .0 0 2～ 0 .0 0 4mm ,表面粗糙度可达到Ra0 .0 8～ 0 .1 6 μm (采用W1 0油石 ) ,最高可达Ra0 .0 4～ 0 .0 8μm ,尺寸精度可达IT5,可获取以珩代研的效果 .
Starting from the analysis of existing problems in existing tools both at home and abroad, this paper focuses on solving the problems of large deviation and large roundness errors in the precision deep hole honing process of superhard materials. A three-oriented BTA honing tool structure , So that the quality of ultra-hard precision small deep-hole processing has been improved.Experiments have shown that the use of new honing tools can be made of small deep hole deviation can reach 0. 0 0 1 ~ 0. 0 2mm / 1 0 0mm, Taper 0 0 0 5mm / 1 0 0mm, roundness error 0 0 0 2 0 0 0 0 4mm, the surface roughness can reach Ra 0 0 0 ~ 0 1 6 μm (with W1 0 oilstone), the highest The Ra0 .0 4 ~ 0 .0 8μm, dimensional accuracy of up to IT5, access to the effect of research by honing.
