Advantages of the Round Dies VX
The dies made of HSSE offer many other advantages in addition to the possibility of machine use.
The gun nosed chamfer causes an intentional controlled chip removal into the cutting direction and a reduction of the cutting torque. This optimal chip removal improves the surface quality of the cutted thread. A plugging of the chip holes is avoided and there is a significant increase in the running life of the application.
Furthermore, the dies from our VX series are lapped. This means that the surface roughness of the cutting tool is reduced by means of a further production step. This results in a better and easier cut during use and the surface of the thread is also optimized. The lapped design also allows a more accurate work when using the die by machine.
The steam tempered surface leads to a better adhesion of the coolant and lubricant. This reduces the risk of the lubricant film breaking off and it avoids cold welds forming in the thread of the die.
