The Best Choice on Cutting Tools on processing steel parts
Due to the high hardness when processing gear steel, the choice is a cutting tool of processing steel parts, but it always is not wear-resistant, what is the reason?
Gear steel hardness after heat treatment is generally above HRC45, some machinery manufacturers chose carbide cutting tool or coated cutting tools, but also specifically aiming at the steel parts to developed cutting tools, but it always not wear-resistant, processing efficiency does not improve, but also need change cutting tool frequently. But we do not know what the cutting tools can be effectively processed high hardness steel gears.
In fact, many small and medium sized machinery manufacturers do not know CBN inserts can process high hardness gear steel, they only know that carbide cutting tools can processing steel parts, but it was unclear processing steel parts hardness. For steel parts of hardness HRC45 or less, we choose carbide cutting tools effect is indeed better, but for processing high hardness steel gears CBN inserts select is the most suitable.
Halnn Superhard, as cubic boron nitride inserts manufacturers, specifically aiming at high hardness steel gears after heat treatment developed BN-H20 grades and BN-H11 grades CBN Cutting tools. These two kinds of cutting tools belong to welded CBN inserts, depth of cut is less than 0.5mm,it can be high speed cutting, processing efficiency is dozens of times of carbide cutting tools. And Halnn Superhard BN-H20 grades CBN inserts can be used for interrupted turning gear steel to solve the problems of conventional cutting tool often chipping in interrupted processing gear steel .
