Welcome to EHWA PMC, the Ehwa's official Precision Machining Cutting tools Website. You could find various grades for your best tooling performance. On this page, you will see all Ehwa's line-up as well as Standard stock items for your quick test and order plan.
EHWA DIAMOND - PCBN APPLICATION (HARD TURNING)
Hardened steel machining :when machining heat-treated steel using a PCBN tool, it is important to check if the workpiece has interruption. The reason is that workpiece shape and PCBN grade have close relationship for working area varies according to the characteristic of the PCBN grade.
EB428
EB419
EB454
EB19X
EHWA DIAMOND - PCBN APPLICATION (POWDER METAL)
Powder metal can be divided into high-alloyed metal and low-alloyed metal, and they have different properties and hardness. Ehwa pcbn grade has excellent wear resistance and toughness, so it can improve tool life and and surface roughness.
EHWA DIAMOND - PCBN APPLICATION (CAST IRON)
Cast iron machining: Pcbn is excellent in processing grey cast iron, ductile cast iron, and high hardness cast iron. Compared to conventional tools, it is possible to cut at a high speed, and it is possible to obtain an excellent surface and the life of the tool.
