DE-1: Lesson 12. INTRODUCTION TO MILLING

A milling machine may also be used for drilling, slotting, making a circular profile, gear cutting or helical milling with suitable attachments. Generally the work piece is fed past the rotating cutter but sometimes feed may also be given to the cutter. The teeth of the cutter act as individual cutting edges each producing a small chip of its own.

Grinding process of helical micro-drill using a six

Helical drill point is characterized by a continuous helical flank surface and an S-shape chisel edge, and its special geometry contributes to a superior drilling performance and a better grinding efficiency. However, the existing grinding processes are complicated and hard to be reproduced in practice, and it is difficult to meet the accuracy requirements as the drill diameter becomes smaller.

Making helical gears on a vertical milling

The main and probably only drawback is that the setup for helical milling on a vertical machine is not as rigid as it would be on a horizontal machine. The trick here is that the gear cutter is held on a stub arbor held in the vertical socket. But the vertical head is tilted. This tilt sets the required helix angle.

Video: Helical Interpolation Vs. Drilling Modern

Helical milling video courtesy Makino A machining center able to maintain precise control at high feed rates makes it practical to machine holes through helical milling as an alternative to drilling. The same speed permits faster drilling, too, so helical milling won’t necessarily be the best approach.
