Six major classifications of cutting machine blades

Standard cutting machine blades can be divided into the following six types based on the hydraulic transmission cutting method of the cutting machine 1、 The blade of a manual shearing machine is used

Vacuum heat treatment cutting machine blade technology

The cutting blade process of the cutting machine has been widely used in the manufacturing of hydraulic cutting machine blades and CNC cutting machine blades, especially for high-precision cutting mac

Hardness testing

test method The hardness testing of hard alloys mainly uses a Rockwell hardness tester to test the HRA hardness value. The PHR series portable Rockwell hardness tester is very suitable for testing the

Preparation of hard alloy

The production of hard alloy involves mixing tungsten carbide and cobalt in a certain proportion, pressing them into various shapes, and then semi sintering them. This sintering process is usually car

Classification of hard alloy shapes

Spheroid Hard alloy balls are mainly composed of micron sized powders of carbides (WC, TiC) from high hardness and refractory metals. Common hard alloys include YG, YN, YT, and YW series. The commonly

Classification of hard alloy alloys

① Tungsten cobalt hard alloy The main components are tungsten carbide (WC) and binder cobalt (Co). Its brand name is composed of "YG" (the initial Chinese pinyin of "hard and cobalt&quo

Properties of hard alloy materials

Hard alloy is a powder metallurgy product made by sintering high hardness refractory metal carbides (WC, TiC) in micrometer sized powders with cobalt (Co) or nickel (Ni), molybdenum (Mo) as binders in

Performance characteristics of hard alloys

High hardness (86-93HRA, equivalent to 69-81HRC); Good thermal hardness (up to 900-1000 ℃, maintained at 60HRC); Good wear resistance. Hard alloy cutting tools have a cutting speed 4-7 times higher th

Hard alloy applications

In 1923, Schlester from Germany added 10% to 20% cobalt as a binder to tungsten carbide powder, inventing a new alloy of tungsten carbide and cobalt, with a hardness second only to diamond. This was t
