PCD PCBN Cutting Tools Diamond Insert PCD CBN Cutters

 Introduction

PCBN is made by high pressure high temperature sintering of cubic boron nitride with a binder pahase, and there are mainly tow groups of binders, namely metal binder and ceramic binder. CBN and diamond are very similar in crystal structure, chemical bond and lattice parameters, thus they perfotm quite similar hardness and strength,. In cutting applications, the wear resistance of PCBN exceeds 50 times that of tungsten carbide.

Application

PCBN is typically recommended to machine ferrous materials such as hardened steel components over the range 45 to 70HRc and grey cast irons. The material combines high hot hardness, chemical stability and abrasion resistance to provide an effective solution for machining these very different work-piece materials.

Usages

1. PCBN blades are mainly using in processing of hardened steel whose hardness is of HRC50-60. such as: carbon tool steel, bearing steel, die steel, high-speed steel and so on. It also using in processing of gray cast iron, ductile iron, chilled cast iron, and other high temperature alloy and so on.

2. PCD tools are using in cutting of non-ferrous metals (such as copper, aluminum, magnesium, etc.) and non-metallic materials (such as fiberglass, ceramics, reinforced plastics, etc.)

Products feature

1. PCBN cutting tools, which also known as cubic boron nitride(CBN) blade, has high hardness and excellent thermal stability.

2. PCBN inserts’ cutting temperature can reach 1300°C.

3. PCD tool, also known as polycrystalline diamond blade, has high hardness, excellent wear resistance, low friction coefficient, and excellent thermal conductivity.
