Tooth attack is widely used in machining mechanical parts. How to choose a good tapping machine is particularly important. Below I give you the tapping, the handling of tapping machines for each person to understand their own working principle according to the better equipment and equipment of their own choice.
There are 3 common tapping machines:
A pair of gears, connecting axes, and connecting axes. So the rotating and moving tools can spiral.
The spindle is connected with the thread gauge. On the nut gage, move back. Because the nut is fixed in the power head body, the nut is not rotated. So when adjusting the rotation of the teeth, it will drive the spindle and rotate the teeth marks according to the track.
Servo tapping: no need to use thread gauge. Servo motors are used for each feed of the shaft and the rotating shaft. Motor control system, spindle speed and feed rate, thus forming tracks along the thread spindle rotation.
The solution and suggestion of deep hole drilling tapping machine is because titanium parts are difficult to process, so we should give full consideration to cutting parameters and cutter geometry.
The cutting speed of titanium alloy has high elasticity and deformation rate. Therefore, the cutting speed of pneumatic tapping machine is relatively small. In the processing of titanium alloy parts, pneumatic tapping machine is circular cutting speed recommended 10 to 14 inches per minute. We do not recommend the use of smaller speeds, because this leads to cold hardening. In addition, tool breakage caused by cutting heat should also be paid attention to. Deep hole tapping requires reducing the tap space and the chip space of each slot. Therefore, when the tap is retracted, more iron can be taken, because the chance of tool breakage decreases because of the iron plug. But on the other hand, the tap groove increases the core diameter, so the development intensity is affected. So this will also affect cutting the small front angle to improve the strength of the cutting edge, thereby improving the tool life; and cutting the metal scrap with the big front corner is long. Therefore, in the process of titanium alloy, these two factors need to be considered, and the proper front corner should be chosen. The friction between tool and chip can be reduced at a large angle. So sometimes after the angle is needed, the faucet is 40 degrees. In titanium alloy processing, the angle of tap wear is large, which is beneficial to the chip. In addition, grinding taps and edge grinding are also beneficial to tapping.
