What is pdc cutter?

Pdc cutter is made by sintering the diamond powder and cemented carbide substrates under ultra-high pressure and high temperature. It not only has the high hardness, high wear resistance and thermal conductivity of diamond, but also has the strength and impact toughness of hard alloy. It is the ideal material for manufacturing cutting tools, drilling bits and other wear-resistant tools.

pdc cutter is a kind of composite material composed of diamond and hard alloy matrix, which has the characteristics of high hardness and good abrasion resistance.

Drilling mining pdc cutter: suitable for soft to medium hard geological drilling, the impact toughness and high thermal stability, heat resistance temperature can reach 750 ℃ (two minutes), these products have plane and various groove surface type, according to user needs and design type slot, grinding, polishing and chamfering, etc., can provide products with special shape.

Pdc cutter for mechanical cutting tools: suitable for cutting high hardness alloy, wood, ceramic and other non-metallic, nonferrous metal and other metal cutting and processing, has the high hardness and wear resistance, high cutting precision, at the same time according to user needs, will be growing product processing square, triangle, fan and other shapes, can be used for making wear-resisting devices, drill bit, top, and bit teeth (such as spherical shape, cone).

Development direction of pdc cutter

Development direction of pdc cutter mainly includes:

1. The pdc cutter layer is continuously thickened from less than 1mm initially to 2-4mm now, and the product life is also improved.

2. The grain of diamond becomes finer and finer, and the comprehensive performance of wear resistance and impact resistance is improved.

3. Improve the thermal stability by optimizing the process or removing Co and adding heat resistant layer.

4. Optimize the interface structure and improve the interface stress.

5. The product diameter is continuously increased to improve the synthesis efficiency.

6. Improve sintering effect and reduce performance difference.

Synthetic pdc cutter is a kind of superhard material.

Superhard materials are those with high hardness (HR), brinell hardness (HB) and vickers hardness (HV).

The general 45# steel HR is 30-60, the hardest natural diamond.

This concept covers a wide range, including high hardness steel, high hardness ceramics, artificial diamonds and so on.

With the progress of technology, the industry has developed a new type of pdc cutter, including roof, steel helmet and bread slices with the following special shaped pieces. Without affecting the wear ratio, the impact toughness of the pdc cutter sheet has been greatly improved, and the technology of pdc cutter sheet has been promoted to a new level.
