Press brake tooling is the tool used on press brakes to shape and process sheet metal. These tools consist of various components, with different tooling composed of different parts. They primarily achieve the processing of the external shape of an item by changing the physical state of the formed material. They are used to transform the blank into a component with specific shapes and dimensions under the pressure of the press brake.
Material Selection for Press Brake Tooling: Generally, T8 or T10 is used, and better options include 42CrMo, which requires high strength, toughness, and good wear resistance. Cold work tool steel is a suitable choice. Cr12MoV is an excellent material, meeting the performance and process requirements, although it may be relatively expensive. 42CrMo is a high-strength alloy quenched and tempered steel with high strength and good toughness. It can work below 500 degrees Celsius. Other options include T8, T10, 42CrMo, and Cr12.
Standard Tooling for Press Brakes
Press brake tooling is divided into upper and lower tooling, used for sheet metal stamping and separation. The forming tooling has a cavity, while the separation tooling has a cutting edge.

Looking at the development history of CNC press brake tooling, from the late 19th century to the mid-20th century, high-speed steel represented the main material for CNC press brake tooling. In 1927, Germany first developed hard alloy CNC press brake tooling materials, which were widely used. In the 1950s, Sweden and the United States synthesized artificial diamonds, marking the era of CNC press brake tooling dominated by superhard materials. In the 1970s, people used high-pressure synthesis technology to produce polycrystalline diamond (PCD), solving the problem of scarce natural diamonds and high prices. This expanded the application of diamond CNC press brake tooling to multiple fields, including aviation, aerospace, automotive, electronics, and stone industries.
The selection of materials for CNC press brake tooling is the foundation for successful cutting processing. Compared to cemented carbide, PCD CNC press brake tooling can reach speeds of up to 4000m/min, while cemented carbide is only a quarter of that. In terms of lifespan, PCD CNC press brake tooling generally improves by 20 times. In terms of surface quality of the processed parts, PCD performs 30% to 40% better than cemented carbide. Additionally, the development of CBN (cubic boron nitride) superhard material CNC press brake tooling and surface coating CNC press brake tooling has significantly contributed to the advancement of cutting processing technology.
