Halnn takes you on a journey through the evolution of PCBN/PCD inserts

The history of tool materials is a long and continuously improving process.

From the early days of alloy tool steel to the modern superhard materials, Every change has greatly promoted the development of manufacturing industry. These are analysed below: The earliest as cutting tools is alloy tool steel tools: alloy tool steel is based on carbon steel with a certain proportion of alloying elements (such as chromium, molybdenum, silicon, etc.) formed, with a certain degree of hardness and abrasion resistance, in the late 18th century there have been milling cutters, taps, twist drills and other products

With the deepening of the industrial revolution, the requirements for cutting speed and efficiency increased. As a result, high-speed steel cutting tools appeared in the late 19th century. Due to their good wear resistance and toughness, high-speed steel cutting tools are currently used in many drill bits.

Following the high-speed steel cutting tools, is the pre-20th century carbide cutting tools, the emergence of carbide cutting tools marks the cutting tool materials into a new era, carbide cutting tools from refractory metals (such as tungsten, titanium) carbide powder and binder (such as cobalt or nickel) mixed with the press after high-temperature sintering and become, has a very high hardness and abrasion resistance, including non-metallic and ferrous materials can be processed. It is also a mainstream tool on the market.

Ceramic cutting tool is developed after the carbide cutting tool, the time difference is not much time.Ceramic cutting tool hardness is higher than carbide cutting tool.They are mainly used for cast iron, hard steel, high temperature alloys and other fields. However, because of their high brittleness, they are generally not recommended interrupt cutting conditions, it only has obvious advantages in certain subdivisions and has not been well developed.

After the progress of modern manufacturing industry, more and more difficult to process materials. The development of metal cutting process, especially high-speed cutting, dry cutting and the emergence of turning instead

of

grinding

process.Increasingly

stringent

technical

requirements have been put forward for metal cutting tools, thus superhard tools-CBN tools and diamond tools were born.

CBN tools and diamond tools, are the use of artificial methods in the high

temperature and high pressure synthesis of Artificial CBN/PCD cutting tools.They combine high hardness, high wear resistance, toughness and good chemical stability. CBN tools in the cast iron high-speed cutting, hard steel interrupt cutting, heavy-duty cutting and other areas of excellence.Diamond tools in the field of composites, graphite, ceramics, aluminium alloys and other non-metallic and non-ferrous metal materials are widely used.

This is the development history of cutting tool materials, a magnificent poem woven by wisdom and innovation. Every progress is a carving of the future, and every innovation is a tribute to craftsmanship.
