Product Description
Xiyangyang Steel Wire Screw Sleeve Tap is used to process blind hole bottom hole. It can produce chips quickly and has high precision. It can process the bottom hole.
Company Profile
Bolt screw sleeve is a special fastener with internal and external threads, and four or two bolt keys on the external thread. The bolt screw set is inserted into the bottom hole after tapping, and then four bolts are pressed into it to play a strong fastening role. Products are mainly used in, aerospace, railway locomotive, vibration machinery and other products with higher thread strength requirements.Select the type of tap
We often use: straight groove tap, spiral groove tap, screw tip tap, extrusion tap, its performance has its own strengths.
Straight groove tap has the most versatility, through holes or through holes, non-ferrous metals or ferrous metals can be processed, and the price is also the cheapest. But the pertinence is also poor, anything can be done, nothing is the best. The spiral groove tap is more suitable for processing through the hole thread, and the chip is discharged backward during processing. Because of the screw Angle, the actual cutting Angle of the tap will increase with the increase of the screw Angle.
Experience tells us: for the processing of black metal, the helix Angle is a little smaller, generally around 30 degrees, to ensure the strength of the helix teeth. Processing of non-ferrous metals, the spiral Angle is selected a little larger, can be about 45 degrees, and the cutting is sharp. The chip is discharged forward when the screw tip tap is processed. Extruded tap is more suitable for processing non-ferrous metals.
