The CMA electric tapping machines have a 230V electronic brushless single- phase motor together with a pantographic arm of CMA's own design. This is all mounted on a tabletop arm mounting bracket. Through the control panel you can configure the different existing configurations.
It has a tapping depth programmer, so when it reaches the programmed depth, the motor stops automatically and turns counterclockwise. In addition, to control the speed we added a CMA design gearbox with continuously variable speed.
