Product catalog summary

Introduction to PCD Cutting Tool Materials

Polycrystalline Diamond (PCD) is a super-hard cutting tool material synthesized since the 1970s using High Pressure High Temperature (HPHT) methods. It serves as an advanced alternative to natural diamond and traditional materials like high-speed steel and carbide. PCD is widely applied in aerospace, automotive, electronics, stone machining, and other industries.

Key Advantages of PCD:

Random grain orientation eliminates directional hardness variations.
Direct sintering to tungsten carbide backing enhances shock resistance.
Capability to produce large tool blanks suitable for milling and large cutting tools.
Compatibility with laser cutting, polishing, and EDM machining for custom sizes.
Customizable properties tailored to specific application needs.

PCD is primarily used for machining non-ferrous metals, alloys, composites, carbides, ceramics, reinforced plastics, wood, and automotive components.

Material Microstructure and Performance

The microstructure of PCD influences wear resistance, fracture toughness, and edge-sharpening performance. Fine grain sizes provide superior surface finishes compared to conventional grain sizes.

PCD and PCBN Insert Specifications

The document details specifications for various PCD and PCBN inserts, including:

Insert shapes and types (e.g., 80° hexagon, positive/negative types, with or without mounting holes).
Dimensions such as inscribed circle (I.C.) thickness (2.38 mm to 4.76 mm), hole diameters (6.35 mm, 9.525 mm, 12.7 mm), and cutting edge lengths.
Cutting edge configurations with positive rake angles and standard clearance angle of 11°.
Number of cutting edges and cutting directions specified per insert type.
Recommended usage categorized by material types: cast iron, exotic alloys, quenched steel, sintered components, aluminum alloys, non-metal materials, die casting aluminum, copper, and difficult-to-machine materials.
Cutting conditions classified as continuous, medium, and interrupted cuts, with legends indicating suitability.

Product Coding and Catalog Numbers

Each insert is identified by catalog numbers and concentration codes corresponding to specific material grades and cutting conditions. Matching holders are referenced with page numbers for selection.

Thicknesses range from 2.38 mm to 3.97 mm with corresponding hole diameters (6.35 mm, 9.525 mm). Catalog numbers such as DCG, DCGW, TCGT, WCMT, and others identify specific insert types and sizes.

Recommended materials for these inserts include aluminum alloys, non-metallic materials, die casting aluminum alloys, and copper. Cutting conditions are classified into continuous, medium, and interrupted cuts, with legends guiding optimal insert selection.

Product Identification and Holder Compatibility

Each insert is associated with catalog numbers and appearance codes indicating cutting edge type and coating or treatment. Matching holders are referenced with page numbers to ensure proper mounting and stability.

Best Practices and Recommendations

Select PCD inserts with appropriate grain size to balance surface finish and wear resistance.
Use tungsten carbide backing inserts for enhanced shock resistance in demanding applications.
Choose cutting edge geometry, rake, and clearance angles based on workpiece material and cutting type.
Utilize laser cutting and EDM machining for custom insert sizes and shapes.
Follow recommended usage charts to match inserts with specific materials and machining conditions.
Ensure compatibility between inserts and holders for secure mounting and precision.

Conclusion

Worldia's PCD and PCBN cutting tool inserts offer a comprehensive range tailored for diverse materials and cutting conditions. Their advanced microstructure and manufacturing processes provide superior wear resistance, fracture toughness, and surface finish quality. Proper selection based on material compatibility, cutting edge geometry, and application type is essential to optimize machining performance.

In the course of the development of cutting tools, high speed steel was the major cutting tool materials from the end of the nineteenth century till the mi- ddle of the 20th century. In 1927, carbide tool material was firstly developed in Germany and later on extensively used in coming decades. The successful synthesis of diamond in 1950s increased the applications of super-hard cutting tool ma- Recommended Usage Matching Holder on page No. terials, while the scarcity and high cost of natural diamonds still confined their applications. In 1970s, polycrystalline dia- mond was synthesized by HPHT process, which offered ideal solutions for an expanding range of areas like aerospace, au- tomobile, electronics, stone and so on. Sintered Component 烧结零件 Compared with large crystal mono diamond and traditional CVD diamond, PCD has the following advantages.
