We have 18 sets cylindrical grinding machines with powerful shaft processing capabilities. The 3000mm MM-grade cylindrical grinding machine ensures that the roundness and diameter uniformity within 2000mm of the shaft surface is within 0.005mm. After forging, quenching, quenching, chrome plating and other perfect processes, the wear resistance of the shaft can be guaranteed and the life of the shaft can be improved.
Material: carbide alloy
Hardness: HRC 53-63
Application: slitting line, shearing 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.
