The PDC Cutter produced by the PDC cutter supplier combines a polycrystalline diamond layer for hardness and wear resistance with a cemented carbide substrate for strength and impact resistance.
Polycrystalline diamond composite, a super hard material, is formed by sintering single-crystal diamond micro powder with binders, typically cobalt or nickel, under high temperatures and pressures.
Diamond composites used for drilling are primarily flat, though some specialized shapes include cylindrical or a combination of cylindrical and hemispherical forms.
PDC Cutter combines the hardness, wear resistance, and thermal conductivity of diamond with the strength and impact resistance of carbide.
Standard PDC Cutter is ideal for soft to medium-hard drilling, offering high impact toughness and thermal stability up to 750℃ for two minutes. It comes in flat or grooved surfaces, customizable to user preferences including grooving, grinding, polishing, and chamfering. Special shapes and customization are available.
PDC Cutter is a super-hard composite of diamond and cemented carbide, formed under ultra-high pressure and temperature. Boasting high hardness, wear resistance, and weldability, it's an eco-friendly alternative to traditional alloy tools, reducing resource consumption and environmental pollution, such as metal dust. Its surface, sintered from various diamond powder sizes, provides durability while the tungsten-cobalt carbide base ensures toughness, facilitating brazing and welding to tools. It's ideal for crafting cutting tools, drill bits, and other wear-resistant tools.
PDC (Polycrystalline Diamond Compact) cutters are cutting tools used in various industries, primarily in drilling applications. These cutters consist of a layer of polycrystalline diamond (PCD) bonded to a tungsten carbide substrate. The combination of hardness and wear resistance of diamond with the toughness of tungsten carbide makes PDC cutters suitable for a range of applications including oil and gas drilling, mining, geothermal drilling, construction, water well drilling, coal mining, etc.
Cutters are produced through a synthesis of elevated temperatures and pressures, forming what is known as a PDC (polycrystalline diamond compact) cutter. Man-made diamonds can be cultivated within a remarkably short time frame, ranging from 5 to 10 minutes. This high-speed diamond generation is the reason why a fixed cutter bit is sometimes referred to as a diamond drill bit.
The manufacturing process involves the combination of a carbide substrate and diamond grit. The compact is shaped under extreme conditions, with temperatures reaching around 2800 degrees and pressures soaring to approximately 1,000,000 psi. In this process, a cobalt alloy serves as a catalyst, facilitating the sintering of the carbide and diamond components. The cobalt plays a crucial role in bonding these materials together.
As the assembly undergoes the cooling phase, a notable discrepancy emerges: the tungsten carbide contracts at a rate 2.5 times faster than the diamond. Effectively managing this stress, akin to various aspects of drill bit design, is deemed proprietary knowledge, often safeguarded as Intellectual Property.
