Precision hole machining

2020-05-07 16:57:09

MoreSuperhard materials (PCD diamond and cubic boron nitride) are known for their high hardness, but as industrial teeth, a great many of superhard materials(PCD&PCBN) related products need hole making before they can be used. Such as cutting inserts location hole, PCD diamond scribing wheels’ hole , medical device fluid orifice, water jet nozzle hole, drawing die hole and peeling tools’ hole, other PCD/PCBN wear parts’ hole etc. Our company mainly develops a new making holes’ method for PCD & PCBN materials, and adopts advanced electric processing, laser processing, ultrasonic grinding, honing and other methods to develop different processing technologies for different hole shapes. The hole diameter size can reach the accuracy range of micron meter level and the surface quality of inner hole can achieve the highest mirror effect (Ra0.25).

PCD diamond scribing wheels’ hole:

Mainly for the hole processing of diamond scribing wheel, diamond scribing wheel hole is the benchmark for the work of the cutter wheel, especially for the multi-wheel scribing wheels group is more demanding on the hole size precision, we use electric processing, laser processing, plus special grinding and finishing processes, the hole size precision can be up to 0.002mm, and the surface roughness up to Ra0.5.

    The 2021 Shenzhen International Additive Manufacturing, Powder Metallurgy and Advanced Ceramics Exhibition (Formnext+PMSouthChina) have been held in Shenzhen International Convention and Exhibition Center from September 9 to 11. Shenzhen, known as the "capital of scientific and technological innovation", has thus shown infinite vitality. Nearly 200 outstanding exhibitors from home and abroad bring world-leading technologies to this 15,000-square-meter event to provide a broad market opportunity for the manufacturing industry in South China. MoreSuperHard has sent two representatives to Shenzhen International Convention and Exhibition Center to participate in the exhibition and exchange learning.

  • Application of CBN inserts in cutting chilled cast iron roll

    Application of CBN inserts in cutting chilled cast iron roll

    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 there are often defects such as impurities and hard spots in the roll blank. When using tools for processing, the defects of the roll itself will cause severe impacts on the tools, and the increase in cutting temperature will increase the wear of the tools, so it is a kind of material that is more difficult to process.
