PRODUCT DETAIL

There are significant differences between MCD Inserts and PCD Inserts in terms of materials, manufacturing processes, and application areas. ‌

Materials and manufacturing processes

MCD Inserts: Use high-purity artificial single crystal diamond as the material, obtain single crystals through high temperature and high pressure synthesis technology, and then perform shape design and edge trimming. ‌

PCD Inserts: Use polycrystalline diamond (Polycrystalline Diamond) as the material, and combine it with metal through high temperature and high pressure technology to form a tool blade. ‌

The differences between MCD Inserts and PCD Inserts are as follows:

1. Application differences

MCD Inserts is almost exclusively used for high-precision finishing, and its extremely thin cutting ability can ensure extremely high dimensional accuracy.

PCD Inserts are suitable for processing aluminum and other non-ferrous alloys with good toughness (such as copper, brass and bronze), as well as highly abrasive composite materials (such as graphite, carbon-carbon materials, carbon-added phenolic, glass fiber and porous sealing materials). And PCD is more suitable for rough processing and processing occasions with high requirements for tool fracture toughness.

2. Differences in tool edge and processing

A: The condition of polycrystalline diamond (PCD) and MCD Inserts under a metallographic microscope. It can be clearly seen that the edge of the blade of polycrystalline PCD will be jagged, while the single crystal diamond is smooth.

B: Differences in processing. The Inserts of polycrystalline diamond (PCD) tools is composed of many fine crystals, so during machining and turning, the surface of the workpiece will also show traces caused by small grains. MCD Inserts can directly copy the perfect state of the Inserts on the workpiece.

To sum up, this is the difference between single crystal diamond tools and PCD tools. In general, PCD tools, which are known for their durability in non-ferrous metal processing, are more widely used than single crystal diamond tools. However, in ultra-precision processing with high finish requirements in the optical industry, precision component accessories, medical equipment, 3C industry, etc., the advantages of single crystal diamond tools are far greater than PCD tools.

At SCBN TOOLS, all types of customized inserts are available for you.
