In the machining of materials such as cast iron and hardened steel, in addition to integral polycrystalline PCBN inserts, hole-locating PCBN inserts with cemented carbide substrates (such as integral brazed, composite brazed, integral composite, etc.) are also widely used.

However, with the continuous fluctuation of cemented carbide raw material prices, the prices of PCBN inserts with cemented carbide substrates also fluctuate accordingly, bringing significant cost pressure to tool manufacturers and end users.

For tool manufacturers and end users, how to optimize insert structure and reduce overall usage costs while ensuring machining requirements has become an issue worthy of attention.

Berlt PCBN integral dimple inserts, with an integral PCBN structure without a cemented carbide substrate + customized dimple geometry, provide a more cost-competitive alternative to traditional hole-locating PCBN inserts with cemented carbide substrates.

I. No Cemented Carbide Substrate, Reducing Raw Material Cost Pressure

Traditional PCBN inserts with cemented carbide substrates require cemented carbide as the substrate material. Rising cemented carbide raw material prices will inevitably bring pressure on the manufacturing costs of related products.

Berlt PCBN integral dimple inserts adopt an integral PCBN structure without a cemented carbide substrate, no longer relying on the cemented carbide substrate in traditional composite inserts, getting rid of the direct impact of cemented carbide raw material price fluctuations on product costs, and providing better cost optimization space for PCBN inserts.

II. Replacing Traditional Hole Location with Innovative Dimple Location, More Stable in Use

PCBN integral dimple inserts adopt a dimple location design, do not require a traditional central through-hole, and replace the combination of PCBN and cemented carbide substrate with an integral PCBN structure.

The center of both sides of the insert is designed with locating dimples, fixed by locating pins + pressure plates. This structural form ensures the continuity of the overall structure, higher overall strength, stronger impact resistance, and more stable insert life, making it more suitable for high-speed turning.

III. PCBN Integral Dimple Inserts, Better Cost Optimization Space

·Reduce dependence on cemented carbide substrates: no need to use the cemented carbide substrate of traditional insert structures, reducing the cost pressure brought by fluctuations in related raw material prices.

·Optimize PCBN insert structure: adopt integral PCBN and dimple location design, providing a solution different from traditional hole-locating composite structures for insert manufacturing and material configuration.

·Improve the economy of tool selection: on the premise of meeting machining requirements, provide customers with a new choice to optimize insert procurement costs and overall usage costs.

The value of PCBN inserts is ultimately reflected in machining applications. Structural design must serve machining needs, and cost optimization must also be built on the basis of meeting machining requirements.

Berlt PCBN integral dimple inserts, with an integral PCBN structure and dimple location design, provide a new alternative to traditional hole-locating PCBN inserts, helping customers optimize tool costs and improve the economic efficiency of product use.
