Automatic chip removal device for PCB drilling machine

摘要: The invention discloses an automatic chip removal device for a PCB drilling machine. the machine comprises rack, drill bit, first sleeve, air cylinders, second nylon pad, sleeve and nozzle. In work process, cylinders act to push slide downwards, so that part be machined is pressed by pad; then compressed blown into through quick coupling directly sprayed bit machining portion nozzle fixedly connected with chips generated in process are up discharged pipe joint. simple structure, removed effectively, cooled service life of prolonged, quality improved; located auxiliary manner, size accuracy improved.
