As you all know, pneumatic precision drilling power head of the main structure, feed movement, and by the main control system of three parts, the following, PURROS give you detailed introduce the three characteristics.

1, the main movement

Electrical, pneumatic, automatic feed drilling head of the main movement driven by three-phase asynchronous motor, the synchronous cog belt and spline shaft of the motor torque is transmitted to the spindle, the spindle speed can be change by different synchronous cog belt wheel. Due to the main movement driven by motor power head, spindle speed characteristics, power output and torque is big, can adapt the multi-axis drilling and large aperture processing conditions.

2, feed movement

Because of pneumatic transmission has quick response, good adaptability to the environment, some advantages such as simple structure, small volume, and can realize stepless speed regulation, long working life, convenient power source, therefore, head of the feed movement using compressed air as power source. Considering the compressibility of air, when the load changes of power head movement is poorer, the workers into the speed adjustment and control of the hydraulic damper is used to realize, power head fast rewind and fast forward with the exhaust valve to adjust.

3, the control system

Electrical, pneumatic, automatic feed drilling power head feed movement using the compressed air as power source, its feed movement control also USES the pneumatic control system, by a two to five ventilation control valve, a motorized valve, two manual valve, a number of throttle valve and two external control air supply port, compact structure, with functions of manual operation and remote control and in situ, before a signal and reset signal protection function. Power head ride fast and work on routine can quickly through the block iron continuous adjustable.
