Notice for drilling machine
1. Choose the right bit or drill according to the material you have drilled.2, according to the material to adjust the appropriate speed, the speed is too fast, drilling hair heat, low melting point material will soften, the speed is too slow, soft material will occur adhesion.3, according to the drill hole depth and aperture, determine the drilling machine feeding times.4, drilling machine is high-speed rotating feed, we need to pay attention to safety protection.5, pay attention to ensure the sharpness of the drill bit, regular grinding or replacement of drill bit.6, the drill shaft should be regularly lubricated.
