Wire thread insert is a very useful fastener, and it is widely used in many industries, but the installation of wire thread insert is a very technical work. The tools required to install the wire thread insert are drill, tap, installation tools, etc.
First step, drill a hole. Drill bit is required when drilling. Select the right drill bit according to the installation guide aperture of the wire thread insert, so as not to cause too loose or too tight thread after installation.
The second step is to tap the teeth with a tap. For the selection of tap structure, the principle is that through hole tapping should choose straight groove tap; Blind hole can only use spiral groove tap. Spiral groove tap introduction: Spiral groove tap is upper chip discharge, cutting speed is fast, suitable for processing deep blind holes, is a commonly used one, according to different working conditions with different spiral angles, the common is right-turn 15° and 42°.
Generally speaking, the larger the spiral Angle, the better the chip removal performance. Suitable for blind hole machining. Of course, through holes are also possible. Usually has the following characteristics: can tap to the lower part of the blind hole; Cutting will not remain; Easy to eat into the bottom hole; Good machinability. Straight groove tap introduction: Straight groove tap structure is simple, the edge inclination is zero, the cutting layer area of each cutter is a step increase, easy to produce vibration, the main cutting effect is the top edge and two side edges. Because the small diameter tap thread profile is not grinding, the cutting Angle is zero, the ironing pressure and friction generated during cutting are very large, and the tapping torque is large.
The third step is installation, installation can use manual or power tools, in the installation must ensure that the wire thread insert vertical and need to be installed parts, so as not to distort or cause inaccurate thread holes after installation.
The fourth step is to remove the tail handle, remove the tail handle can choose a professional tool or with the help of bolt thread rod and hammer to complete, but must pay attention to the strength, so as not to cause damage to the thread insert.
