The Performance of the PCD Cutter

In the manufacturing industry, enterprises are using a large number of advanced CNC machining equipment, but if there is no corresponding good performance of the cutting cutter, the good machine tool will not be able to play its role. As a result, good cutting cutter performance will have a significant impact on the service life, processing efficiency, parts processing quality, and the overall cost of the enterprise.

Ⅰ. Basic performance of the PCD cutter

The choice of tool material has a great influence on tool life, machining efficiency, machining quality and machining cost. Cutting tools are subject to high pressure, high temperature, friction, shock and vibration. Therefore, the tool material should have the following basic properties:

1. Hardness and wear resistance are the first two factors. The cutter material's hardness must be higher than the workpiece material's, usually in the range of 60 HRC or above. The harder the cutter material is, the more resistant it is to wear.

2. Toughness and strength. The material of polycrystalline diamond cutters should be tough and strong to endure cutting pressures, impact, and vibration, and to prevent brittle fracture and chipping.

3. Heat resistant. The cutter material should have good heat resistance, be able to handle high cutting temperatures, and be resistant to oxidation.

4. Process efficiency and performance. The material of polycrystalline diamond cutters should have good forging, heat treatment, welding, grinding, and other performance characteristics, as well as a high performance to price ratio.

Ⅱ. What is the PCD cutter?

PCD (polycrystalline diamond) cutters have been used to prepare polycrystalline diamonds since the early 1970s, using high temperature and high pressure synthesis technologies. Since the successful development of PCD blades in the early 1970s, polycrystalline diamond has been created utilizing high-temperature and high-pressure synthesis technologies, and has been substituted by polycrystalline diamond on numerous occasions.

PCD cutter is a plentiful source of raw materials, and its price is only a few tenths to a dozen percent of that of natural diamond, resolving the problem of scarce and expensive natural diamond and extending the application of diamond cutter to a wide range of fields including aviation, aerospace, automotive, electronics, and stone.

With the advancement of automobile light-weighting, a huge number of aluminum alloy materials are being used in the production of automotive parts, posing a serious challenge to the cutting cutter. The PCD material has a high wear resistance, low coefficient of friction, and high thermal conductivity, making it the best choice for cutting aluminum alloy parts and providing the best guarantee for high efficiency, high precision, high surface quality, and low cost requirements for automotive industry parts.

To summarize, the development of the PCD diamond cutting tools follows the development of the market and fully solves the needs of the users, which is critical to the PCD diamond cutting tools being utilized by users. Simultaneously, as the automotive market has grown in recent years, more and more materials will be employed in the construction of automobiles. In the market for diverse production materials, an improved PCD cutter will undoubtedly play a larger role, bringing actual profitability and competitiveness to the relevant manufacturing firms.
