Polycrystalline Diamond

Polycrystalline Diamond (PCD) is a composite material consisting of diamond and cemented carbide, which is usually produced by assembling diamond powder with cemented carbide matrix by adding a certain amount of bonding agent and then sintering under ultra-high-temperature and high-pressure conditions.

product description

(1) PCD in the automotive and aerospace applications

PCD tools in the automotive field are mainly used for processing the skirt of the engine piston, pin hole, cylinder block, gearbox and so on. Due to the high silicon content of these parts (more than 10%), the service life of the tool requirements, and PCD tool durability is 1-50 times the carbide tool, can ensure the stability of the size of the parts, and can greatly improve the cutting speed, machining efficiency and surface quality of the workpiece.

In the aerospace field, the use of PCD tools processing aluminum alloy (AlSi2) cylinder head, cutting rate is higher, and tool life than cemented carbide to improve about 20 times, the surface quality of the workpiece is also greatly improved.

(2) PCD in the wood processing industry applications

Wood processing is also an important area of PCD tool applications. With the rapid development of synthetic panels (medium density fiberboard, particleboard and laminate flooring, etc.), accelerating the demand for super-hard cutting tools, so that PCD tools gradually replace the traditional woodworking tools in the market.

The outermost layer of Al2O3 of laminate flooring is very abrasive to the carbide tool, and the use of PCD tools can effectively solve this problem. Therefore, PCD in the woodworking industry's main market is reinforced composite flooring and high hardness fiberboard processing.

(3) PCD in the electronic processing industry applications

The electronics industry in the production of electrical printed circuit boards more and more demanding, the general tool in use will have a burr, affecting the installation and positioning of electrical components, and the whole printed circuit board is not beautiful; carbide cutting tools in the processing, short life, slow processing speed, low efficiency, poor machining accuracy. The use of PCD tools, high processing efficiency, low processing costs, more widely used.

(4) PCD in the glass cutting and processing industry applications

Cutter wheel made of PCD is mainly used for high-precision, high-quality cutting of LCD screens of electronic products, and at the same time can cut glass for construction and automobile. The mandrel and cutter wheel are made of PCD material, which has the advantages of high processing precision, wear resistance, good consistency, and high service life at the same time, making it an ideal substitute for ordinary glass knives and carbide glass cutter wheels.

(5) PCD in the composite materials industry applications

Using PCD tools to process glass fiber reinforced composites, its tool life is about 60 times that of cemented carbide tools, the single piece processing cost is 1/20 of cemented carbide tools, and the processing accuracy is higher than that of cemented carbide.

PCD

PCD cutting tool blanks

PCD cutting tool blanks be customized to meet our customers' special needs or requirements.

PCD cutting tool blanks are mainly used for cutting and machining non-ferrous metals and alloys such as SI/Al alloys, aluminium, copper and similar alloys.

They are also used to machine non-metallic materials such as wood, graphite, ceramics, plastic, rubber and so forth, where high abrasion resistance and long life are required.

PCD cutting tool blanks

ldeal for diamond saw blades, construction coring and drilling, diamond cutters for edge-trimming, PCD inserts for turning and milling, diamond drill bits for hole-drilling in composite materials and circuit boards, etc.

Performance characteristics of PCD

(1) High hardness and wear resistance

PCD has high hardness, high compressive strength, good thermal conductivity and wear resistance, can be in the high-speed cutting to obtain high machining accuracy and machining efficiency. such characteristics of PCD tools is determined by the diamond crystal state, the structure has a strong binding force and directionality, so that the diamond has a very high hardness.

(2)High machining accuracy

PCD tools have low coefficient of thermal expansion and high modulus of elasticity, thus the tools are not easy to be deformed during the cutting process, and at the same time, the cutting force and cutting temperature can be reduced to improve the tool durability and cutting rate, so as to obtain good machining surface.

(3) High thermal conductivity

The thermal conductivity of PCD is very high, better than silver, copper, and much higher than general cemented carbide, so it is easy to dissipate heat in the cutting process, and the cutting temperature is lower.
