Q: What are the processing methods of tapping machines and threading machines
Answer:
Widely used in mechanical parts processing for tooth tapping, how to choose a good tapping machine is particularly important. The tapping machine that I will introduce to you below is a better equipment and understanding of its working principle for each person based on their chosen product.
There are three common types of tapping machine processing:
A pair of gears, connecting shaft, connecting shaft. So the rotation and movement tools can spiral the trajectory.
Spindle connection thread gauge. On the nut gauge, move forward and backward. Due to the nut being fixed to the power head body, there is no rotation. So when adjusting the rotation of the teeth, it will push the spindle forward according to the track of the teeth.
Servo tapping: No thread gauge is required. Servo motors are used for each feed on the axis and rotating axis. The motor control system, spindle speed, and feed rate form a trajectory to rotate along the threaded spindle.
The solution and suggestion for deep hole drilling and tapping machine, as titanium metal parts are difficult to process, we need to fully consider cutting parameters and tool geometry.
The cutting speed of titanium alloy has high elasticity and deformation rate, so pneumatic tapping machines require a relatively small cutting speed. In the processing of titanium alloy parts, the recommended circular cutting speed for pneumatic tapping machines is 10 to 14 inches per minute. We do not recommend using lower speeds as this can lead to cold hardening. In addition, attention should be paid to tool damage caused by cutting heat. Deep hole tapping requires reducing the number of tap grooves and the chip space in each groove. So, when the faucet retracts, more iron can be used because the chance of tool breakage is reduced due to the iron plug. On the other hand, the tap groove increases the core diameter, thus affecting the development strength. So this will also affect the ability to improve the strength of the cutting edge by cutting small rake angles, thereby increasing the tool life; Cutting metal waste with a large front angle takes a long time. So in titanium alloy processing, it is necessary to consider these two factors and choose the appropriate rake angle. At a large angle, friction between the tool and chips can be reduced. So sometimes an angle of 40 ° is required for the faucet. In titanium alloy processing, the angle of tap wear is large, which is beneficial for chips. In addition, grinding taps and edges are also beneficial for tapping.
