project

Symptom

NGH triangle not used

The triangular working face is severely worn, and the edge is chipped due to the high pressure, and the working noise is large

Using the NGH Triangle

The triangular working surface has almost no wear, no chipping phenomenon, and low working noise

Application in powder metallurgy mold

General powder metallurgy molds, especially magnet molds, have a service life of only about 1 month before NGH coating is used. After using NGH coating, the service life can be increased to about 3 to 4 months. Some powder metallurgy molds have a service life of only 100,000 to 200,000 times before using NGH coating. After using NGH coating, the service life is increased to 400,000 to 600,000 times, and the service life of some special powder metallurgy molds can be increased to 70 times. ~800,000 times, the effect is very obvious.

After comparison test:

After drilling 6000 holes of the coated drill tip, the positions of the holes are all within the range of 3 mil. Due to the serious collapse of the ordinary drill tip, some holes exceed the range of 3 mil, which confirms the drilling accuracy of the drill tip after NGH coating treatment. Better than ordinary uncoated drill bits;

From the drilling test situation, when the drilling life of the coated micro-drill is increased by more than 3 times, the drilling quality fully meets the requirements (the CPK value of the hole position accuracy is less than 3 mil, the CPK value is greater than 1.33, the hole wall roughness is less than 1.2 mil, and the hole wall nail head is less than 1.5 times);

The use of NGH-1 type coating can effectively save more than 30% of the processing cost of the drill bit. At the same time, because the effective use time of the micro-drill is greatly extended, it reduces a lot of downtime for drilling and replacement, directly improves the production efficiency, and brings obvious benefits to users. income.
