The design of the nickel valve is designed to effectively reduce the temperature and nickel base alloy, which is made of high quality metal HSPM materials and can withstand the harsh test of processing these challenging materials. The multi-layer coating layer applied by pdD can be used to improve the service life of the cutter. Extensive research and testing programs have perfected this unique style of faucet to meet the most challenging material.
Dhf-nhi/Semi -bottoming tap
Based on VHFC technology, there is a special ground terrain in the main cutting area, which can produce a smaller, tightly rolled chip. The result is enhanced chip control to prevent the damaging effects of chips in front and down.
10 to 15 ° right hand spiral flute
Additional screw correction “F” (relief)
Chamfering C(2-3 threads)
Blind hole thread
Cd-nhi/plug tap
The design adopts advanced left-handed spiral groove and inverted angular geometry, optimize the chip evacuation in the forward direction, increase the strength of cutting teeth, and improve the service life and process safety of the cutter.
15 ° 8 – left spiral flute
Chamfering D(4-5 lines)
Hole thread
Hard material with high tensile strength
Aircraft engine manufacturers have specific thread requirements, and standard taps are not effectively addressed. Single – hole threaded perforation is a problem, and the cost of a tap is very expensive. The task of EM is to develop a solution for this particular requirement to develop a plane. Air – tap has a negative inclination value, which has a strong cutting edge. This is very effective in hard materials with high tensile strength. This custom tilting Angle can produce a secure tapping process on nickel-base alloy threads.
features
High quality vanadium HDSSE material
To create a 3BDX class tolerances
The surface treatment of silicon nitride increases the surface hardness of the substrate (1000-250 DHV) to increase wear resistance.
4 to 3/8 thread size has a hardened handle
7/16 “to 3/4” has a reduced handle
