Mental working knife are used in a variety of cross shear lines, shearing machines, and cross-cutting equipment. Each shear blade is ground through the machining center and MG plane to ensure eye hole accuracy and overall parallelism. If the length of the shear blade is less than 2000mm, the parallelism can be within 0.01mm. The carbide shear blade uses advanced welding technology and assembly technology to achieve seamless connection. Each shear blade will pass the marble platform and pass the test.
Material: tool steel, die steel, carbide alloy
Hardness: HRC 53-75
Application: shearing machine, paper cutting machine, printing machine etc.
What's the history of alloys?
The first people in the world to make alloys were the babylonians,
who began refining bronze (an alloy of copper and tin) 6,000 years ago.
China is also one of the earliest countries in the world to study and produce alloys.
The bronze (copper-tin alloy) technology was very developed in the shang dynasty (more than 3,000 years ago).
Around the 6th century BC (late spring and autumn period) the sword.
