how to solve the malfunction of multi head drilling machine-尊龙人生就要博旧版

multi head drilling and tapping machines are widely used in the drilling and tapping processing of porous components in the mechanical industry. over time, multi head drilling and tapping machines may also encounter some fault problems. the common summary is as follows:

the multi head drilling machine will mainly encounter the following three situations during operation:

1. blunt thread: refers to the insufficient depth of the threaded teeth tapped by the multi head drilling machine, which is mainly caused by the diameter of the bottom hole being too large or the diameter of the return rod being too small.

solution: to prevent this problem, it is necessary to correctly calculate or select the diameter of the bottom hole and the diameter of the round rod.

2. slippery thread: refers to the disorderly fastening of screw buckles. this is mainly due to the use of blunt taps or plates, which did not apply appropriate pressure during chip removal, and unnecessary excessive pressure during subsequent ammonium cutting, as well as incorrect tool positioning and lack of lubrication and coolant.

solution: to prevent this problem, it is necessary to pay attention not to use a blunt tap or plate, and apply appropriate pressure. after reaming a few teeth, do not apply too much pressure. at the same time, use emulsions, engine oil, etc. as cooling lubricants, and the tools should be correctly positioned.

3. thread breakage: this is mainly caused by the negligence of the multi head drilling machine during operation, excessive operation, blunt thread, chip blockage, failure to reverse in time, and excessive quenching of the thread.

solution: to avoid this problem, it is necessary to avoid using a fishing wire tap and choose a suitable quenching tap. when tapping, be careful and promptly remove chips to avoid blockage. when the screw tap breaks in the bottom hole and needs to be removed, it can be rotated in the opposite direction to exit. if it cannot be rotated in the opposite direction, a spray lamp can be used for annealing, and then the broken tap can be drilled off and re tapped.

the above is a solution for multi head drilling machines. in addition, regular maintenance work should be done to avoid malfunctions and ensure long-term use< br/>
