Grinding Case -How to Grind PCD and Iron Composite Workpieces

2023-10-27 11:29:09

The characteristics of PCD material

The diamond crystals in the PCD diamond layer are disorderly arranged, isotropic, and have no cleavage planes. They have the high hardness, high wear resistance and high thermal conductivity of diamond; the cemented carbide layer as the base has high impact toughness and Weldability. Therefore, PCD is particularly suitable for cutting tools of non-ferrous metals and non-metallic materials and supporting wear-resistant parts of various instruments and equipment.

The characteristics of iron material

In industry, iron is divided into two types: pig iron and wrought iron - pig iron contains 1.7-4.5% carbon, and wrought iron contains less than 0.1% carbon. Characteristics: Excellent fluidity, low cost, good wear resistance, low solidification shrinkage, very brittle, high compressive strength, good machinability. Purpose: Iron has been used for hundreds of years in construction, bridges, engineering components, homes, and kitchen appliances.

We all know how to choose a grinding wheel for grinding a single material workpiece.Usually,we choose vitrified diamond grinding wheel for grinding PCD material workpiece like PCD cutting tools and we choose cbn grinding wheel for grinding iron material.We do not choose diamond grinding wheel for grinding iron,Above 800 degrees Celsius, diamond reacts with iron to form stable Fe3C. When using a diamond grinding wheel to grind iron materials, friction generates high temperatures, causing "nodulation" to occur on the surface of the grinding wheel.

Customer's workpieces

As we can see,this workpiece have three materials need to be processed.The black part in the middle is PCD, the two slender strips are carbide, and the remaining area is made of iron.

Grind the surface of the workpiece smooth so that the PCD will not crack or scratch.

Moresuperhard developed and manufactured 1A1 D350 vitrified diamond grinding wheel for grinding PCD+iron workpieces.

Basis for formulating grinding plan

The hardness of PCD is much higher than iron and cbn grinding wheel can be not used for grinding PCD material.Commonly we do not recommand diamond grinding wheel for grinding iron material,but if the grinding wheel speed is not high and coolant is used when grinding,diamond grinding wheel  also can be used for grinding iron material.

    Ceramic CBN grinding wheel for grinding rotor

    As key equipment in modern energy conversion and power systems, turbines require extremely high precision and quality in their manufacturing and maintenance processes. The grinding of turbine rotor grooves is one of the important processes, which directly affects the performance and life of the turbine. In recent years, ceramic CBN (cubic boron nitride) grinding wheels have gradually become an ideal choice for grinding turbine rotor grooves due to their excellent hardness, wear resistance and thermal stability. This article will explore the application and advantages of ceramic CBN grinding wheels in turbine rotor groove grinding.
