立新机床厂,过去生产硬质合金浮动镗刀是采用碳化硅砂轮在工具磨床上刃磨,在进给量为0.005～0.01毫米(双行程)的情况下,机床工作十分吃力,刃磨一把要5—6小时,镗刀刃口平直度差,有崩刀现象,加工的另件达不到要求。后来采用粒度150号浓度100%青铜结合剂人造金刚石砂轮刃磨浮动镗刀,精度完全达到了要求,刃口平直,光洁度达▽10,工作进给量提高到0.05～0.08毫米,机床工作轻快,一把浮动镗
Lixin Machine Tool Plant, the past production of carbide floating boring tool is the use of silicon carbide grinding wheel grinding on the tool grinder, the feed rate of 0.005 to 0.01 mm (double stroke) of the case, the machine work is very difficult, grinding a 5-6 hours, boring knife edge straightness is poor, a chipping phenomenon, the processing of other pieces of less than the requirements. Later using the particle size of 150% of 100% bronze binder artificial diamond grinding wheel sharpening boring knife, the accuracy of fully meet the requirements of the blade straight, finish ▽ 10, the amount of work to feed increased to 0.05 to 0.08 mm, the machine work light , A floating boring
