What are PCD saw blades?
PCD Blades are blades for circular saws but compared to a standard circular saw blade where the teeth are tungsten carbide tipped, PCD blades have teeth made of Polycrystalline Diamond.
What is a polycrystalline diamond?
Diamond is the hardest material in nature and is the most resistant to abrasion.
Polycrystalline Diamond (PCD) is an artificial diamond produced in a laboratory through a sintering process. It is an extremely resilient material where diamond crystals are bonded to a base material of tungsten carbide.
During the sintering process, the spaces between the PCD grains are filled with a cobalt alloy and the single diamond grains bond to each other.
This results in a material that matches no other in terms of toughness, durability and resistance, making polycrystalline diamond an excellent cutting material and perfect for use in cutting tools especially where the material is particularly abrasive. It also contributes to the diamond tool having a longer cutting lifetime.
Diamond-tipped saw blades are an excellent choice when cutting larger volumes of homogenous material.
In particular, a polycrystalline diamond tipped (PCD) blade will excel in applications such as cutting melamine and HPL coated panel products, solid surface materials such as Corian, cement fiber board panels, and fiberglass, among others, which are all very hard on conventional carbide-cutting tools.
The PCD saw blade is used for cutting and grooving non-metallic materials, nonferrous materials, the particleboard woodworking industry, and the ultra-precision processing industry.
Application of PCD circular saw blade:
* Woodworking industry.Wood Flooring, Particle Board, MDF, Panel Furniture, Cabinet, Firewood, Plywood, Melamine Plywood
* Non-metallic materials. fiberglass, electronic circuit boards, Bakelite, fiber cement board, acrylic board, plexiglass, rigid plastic
* Ultra-precision processing industry. Aluminum, copper rod, engine cylinder, etc.
Advantages of PCD saw blade:
* PCD circular saw blade tipped with high strength, not easy to collapse teeth, good sharpness
* PCD blade’s Sawing end face does not collapse the edge and does not become black, A straight edge angle is good, and can improve the appearance of the product quality.
* The PCD saw blade’s working life is 30-50 times more than carbide saw blades.
How to use a PCD saw blade:
When using a PCD saw blade is important to never have the blade sticking more than 1mm out of the bottom of the substrate.
By allowing the whole tooth to be exposed below the material, the tooth will smash into the bottom of the substrate as it comes back through. This action will weaken the tooth and cause it to shatter or detach itself from the blade.
(Tips: PCD Blades should not be used on ferrous materials, because Polycrystalline Diamond reacts to elements such as iron and cobalt, so this will cause tool deterioration.)
When it comes to diamond saw blades, it is of particular importance to partner with a company that isn’t only expert in PCD tooling technology, but also saw blade technology.
Especially with larger diameter saw blades, the integrity of the saw plate is of paramount importance if the blade body is to stand up to the expected endurance of the diamond tips it is being tipped with.
A diamond blade can be re-sharpened, and the number of times it can be sharpened depends, among other factors, on the height of the diamond tip the blade is manufactured with.
-Typically, our diamond blades have a 6.5mm tip height which can yield up to 12 sharpenings.
-A more economical blade (lower initial cost) is available with a 5mm tip height which will yield about 6 sharpenings.
-With normal wear, about 0.5mm of the PCD is removed with every sharpening.
-Diamond blades can returned to our facility when dull, They require highly specialized machinery to service.
-Some more popular size blades are available from stock, For more information, please contact us today.
