制程说明
说明钻孔机的夹持及钻轴机构
工作内容
由於电路板的钻孔会有不同的尺寸要求，同时电路板是复合材料，所采购的钻孔操作方式业与一般的金属钻孔加工不同，为了达到切割树脂、铜皮、玻纤三者，电路 板钻孔加工采用高速旋转的钻孔加工方式，一般常见的加工转速有8万、10万、12万、16万、20万、30万RPM。这样的高速旋转，所使用的轴承无法采用传统的滚珠轴承而采用较为特殊的气式轴承，因此机台成本跟使用的气动轴承与钻轴转速就有相当的关联。轴承的前端会加上钻针夹持夹头，有双瓣，三瓣，多瓣等不同的设计。作业时是利用伸缩及夹头的斜度来控制钻孔的抓取，因此除了夹头的直圆度十分重要外，在操作中的保养清洁也会影响钻孔的位置精度及孔壁的质量。
那位好心的大哥，大姐，快点帮帮我吧！急......
快啊，那位大哥，大姐，快救救小弟吧！

Because the circuit board drilling have different size requirements, and circuit boards are composite materials, procurement of drilling practices in the industry and the general processing of different metal drilling, in order to achieve cutting resin, Cu, three fiberglass circuit board drilling of the high-speed rotary drilling methods, the general common processing speed is 80,000, 100,000, 120,000, 160,000, 200,000, 300,000 RPM. The high-speed rotation, which can not be used in bearings using the traditional ball bearings used more special air-bearings, machine costs with the use of pneumatic drill shaft bearings with the speed there is a connection. Bearing the forefront together with needle drilling clamping fixture, a two-valve, 3, multi-jaw different design. Homework is the use of scalable and Collet gradient to control drilling programs, in a
