内引导酚醛层压布管保持架在精车内径工序因材料等因素的影响，容易在图1中“A”处掉“渣”，严重影响制品的表面精度，造成大批量废品，经济价值很高，而尺寸精度和其他项目又完全符合产品要求，将其报废十分可惜，因而我们采取了挽救措施：在内径上增车空刀槽，如图2，将掉渣 Guide the phenolic laminate tube cage in the fine car diameter process due to material and other factors, easy to “A” in Figure 1 out of “slag”, seriously affecting the surface accuracy of products, resulting in large quantities of waste, the economic value is very High, while the dimensional accuracy and other items are fully in line with product requirements, it is a pity to scrap it, so we have taken the rescue measures: increase in the inner diameter trolley, as shown in Figure 2, the dregs
