二车间改进了六轴自动车床的管料工艺.主轴每换位一次,在第四和第六工位各切下一个工件,在保证质量的基础上,机台班产量提高了75%,节约原材料3%.改进后的工艺简述如下:(参照附表)第一工位纵向进给完成两个工件的外径精车.横向刀架安装两把刀,其中的一个用来车第一个工件的外倒角.另一刀将第一工件切离工序完成40%,并车第二个工件的外倒角.在第二工位,纵向进给粗车两个工件的内径.该工序因管料表面存在着硬化层,故采用硬质合金刀具.第三工位纵向进给完成两个工件的内径精车.在第四工位纵刀架上装置了接料杆.当
Two workshops improved six-axis automatic lathe pipe material technology.A spindle for each time, in the fourth and sixth station each cut a workpiece, on the basis of ensuring the quality, machine production increased by 75%, saving Raw materials 3% .An improved process is as follows: (refer to the table) The first station longitudinal feed to complete the two workpiece outer diameter fine car.Transverse tool holder to install two knives, one of which used the car first A workpiece outside the chamfering of another knife will be the first workpiece cut off the process to complete 40%, and the second car outside the workpiece chamfering. In the second station, the rough feed two rough diameter of the workpiece. Due to the existence of the hardened layer on the surface of the tube, a carbide cutting tool is used, and the third station longitudinally infeeds the fine-grained double-finished workpiece of the two workpieces.
