Abstract: Power head is machine tool specialist machine main parts, the production stability of the power head is the key, so the power head quality good or bad is very important.
Identify power head quality good or bad standard is mainly from the following aspects:
First, power head core shaft is most critical, keep rotating and reciprocating motion, but also by the force of the work, so must use good material, must strengthen the hard processing, otherwise quite easy to wear, causes the processing effect degradation, Power head jitter increases, and will not be able to process.
Second, bearing portion, directly sets the core shaft periphery, when the core shaft reciprocating motion, also wants to rotate at the same time, bearings to withstand the pressure of work are also great, the quality is quite good.
Third, moving parts, drilling head generally has cylinder, oil cylinder and screw, mainly is undertaking the core shaft reciprocates, and mainly is seal better.
Fourth, shell, mainly production of compact structure, gap is too big, prone to error.
Fifth, the good quality of the belt wheel, the effect will be relatively stable, not easy to swing, driving force is strong.
Sixth, motor, of course the quality better, speed, and torque is better.
Seventh, cutting tools, this is the loss is tasted; choose according to their own conditions.
Power head is machine tool specialist machine main parts, power head production stability is the key, without installing the handle, power head accurate precision of the spindle is bent at the nuclear power head, power had generally in the 0.5 wire. So the knife handle has a great influence in the power head processing. A handle of the heat treatment, standard size, gripping capabilities have an impact on the workpiece. The wear degree also has the very big difference. So when choosing power head, at the same time also should pay attention to the knife handle of the choice.
