There are a large number of carbides in the material of chilled cast iron rolls, which are composed of pearlite, cementite and ledeburite. The hardness of the roll itself can reach 65HRC or more, and ...

When cutting metal, temperatures up to 800 to 900 ℃ are generated in the cutting zone. In this cutting area, the cutting edge deforms and excises the workpiece material. In continuous turning, heat...

In the modern cutting technology processing, the main application of cutting tool materials for PCD and PCBN, this kind of material can complete casting and forging blank high-speed processing, rough ...

PCD (poly crystal diamond) /Diamond, an isomer of carbon, is one of the hardest materials ever found in nature. Diamond tools with high hardness, high wear resistance and high thermal conductivity are...

PCD tools are most suitable for processing aluminum and other tough non-ferrous alloys (such as copper, brass, and bronze), as well as highly abrasive composite materials (such as graphite, carbon-car...

When the workpiece material structure, hardness, allowance is not uniform, the tip is the most vulnerable cutting part of the tool. If the tip first contact with the workpiece, most of the impact forc...

(1) Formation reasons In the part near the cutting edge, the tool-chip contact area, due to the great downforce, the chip bottom metal embedded in the front knife surface of the micro uneven peaks ...

When the workpiece material structure, hardness, allowance is not uniform, the large front Angle leads to the cutting edge strength is low, the process system rigidity is insufficient to produce vibra...
