我们激光打孔试验小组,经过一年多的努力,自制了一台激光打孔机(见图1)。现已打了三种共千余件不锈钢限流片(见图2和表1),零件合格率为90％。原采用的钻头钻孔工艺每班可钻100件左右,激光打孔每班500件左右,提高工效4～5倍,并且减少了打毛刺工作量。 After more than a year of hard work, our laser drilling team has created a laser drilling machine (see Figure 1). Now hit a total of more than a thousand pieces of stainless steel limiting pieces (see Figure 2 and Table 1), parts pass rate of 90%. The original drill bit drilling process can be used to drill about 100 per class, laser drilling about 500 per class, improve work efficiency 4 to 5 times, and reduce the burr workload.
