我厂维修散热片冲压机床时,需要自制长齿条。齿条尺寸为长665mm,模数3mm,齿表面粗糙度Ra1.6。原工艺在万能铣床上用接刀的方法加工。由于二次装夹,对刀,保证不了齿间误差及齿间平行度要求。为此,我们利用旧分度头的斜齿轮箱改装成X52型立铣头转向刀架。改装 I plant heat sink stamping machine tools, you need homemade long rack. Rack size is 665mm long, modulus 3mm, tooth surface roughness Ra1.6. The original technology in the universal milling machine with the knife method of processing. Due to the secondary clamping, the knife, can not guarantee the interdental error and interdental parallelism requirements. To this end, we use the bevel gearbox of the old indexing head to be converted into the X52-type milling head turning turret. Modified
