Abstract
PURPOSE: To keep the drill pressure at a fixed level by providing a pressure sensor between the housing of the spindle of the drilling machine and the driving motor for feeding thereof and controlling the rotational speed of the driving motor for feeding based on the signal of the sensor.
CONSTITUTION: When the drill 16 comes to cut a substance to be machined, the pressure equivalent to the drill pressure acts on the pressure sensor 5. By this, the pressure sensor 5 generates an analog signal and sends the same to an amplifier 11. The signal is converted into a digital signal in an A/D converter 12 and further sent to CPU13. CPU13 makes an operation by comparing this signal with a set value set beforehand in equivalence to the required drill pressure and outputs a signal thus obtained to a control circuit 14 so as to control the rotational speed of the driving motor 10.
