PC material small parts hole need to drill 0.04mm micro hole, depth 0.2mm, installed in Tianjin on the centering machine processing, machine tool spindle speed is low, easy to break the knife, what is a good solution to process?
Some materials are hard, will think that the torque of the spindle of processing is also required to be sufficient, in fact, drilling micro holes, to high speed and precision, if the line speed can not keep up, the drill bit is easy to break, so the Tsugami centering machine is more than 20mm in diameter, up to 80000 rpm / min, the speed is adjustable, the accuracy is within 1um, it is very suitable for drilling micro holes.
Drilling micro holes requires high-speed NAKANISHI high-frequency milling, the quality of the drill bit is also the key, the high speed of the spindle is there, but it also needs whether the drill bit can withstand it, if it can be matched, it will definitely get twice the result with half the effort and improve the processing efficiency.
