What is PCD diamond?
Polycrystalline Diamond (PCD) is diamond grit that has been fused together under high-pressure, high-temperature conditions in the presence of a catalytic metal. The extreme hardness, wear resistance, and thermal conductivity of diamond make it an ideal material for the cutting tools manufacturing.
What is PCD coating?
PCD (polycrystalline diamond) are brazed tipped tools specifically designed for composite, cast aluminum applications. PCD end mills require high spindle speeds and rigid tooling set ups for optimum performance. The PCD insert resists abrasion wear and dramatically extends the milling cutters tool life.
How does diamond coating work?
Deposits of the diamond coatings are realised on cutting plates made in tungsten carbide, which is also the substrate of the commercial plates. The process allows a film deposition of synthesised diamond with a high growth speed, at low energy consumption.
Is CVD diamond real?
Yes, CVD diamonds are real diamonds. Although grown in a lab, CVD diamonds are gem-quality diamonds that have the same elemental structure and the same physical, chemical and optical properties as their natural counterparts.
What is the difference between PCD and CBN?
The advantage of PCD is primarily its consistent high quality – a fundamental pre-requisite for the further machining of tools with the same characteristic. Cubic boron nitride (CBN) is a high-performance tool material from a polycrystalline mass, that similar to PCD is produced in a high temperature-pressure process.
What are diamond end mills used for?
DIAMOND COATING End Mill A cemented carbide end mill where the cutting edge surface is coated with diamond crystals. The end mill where the cutting edge can easily be designed and the shape most suitable for machining a hard and fragile material was developed.
Can PCD cut carbide?
PCD tooling is ideal for cutting abrasive materials which would wear out a standard carbide bit very quickly such as carbon fiber or fiberglass. They are also suitable for cutting chipboard, MDF, particle board, HDF, and many composite materials including solid surface, high pressure laminates and phenolic.
Are real diamonds coated on the back?
Surface coating is a way of enhancing a diamond’s color and is the oldest diamond treatment known, dating back to the Georgian period. The original method of surface coating entailed applying colored tinfoil to the back surfaces of gemstones and diamonds that were mounted in closed-back settings.
