CVD Tools vs. PCD Tools - Which Is The Best For Diamond Machining?

Cutting, machining, and designing diamond were used to be one of the most critical and challenging tasks of the preceding time. But now the time has changed and thanks to the super-advancing technology, we now have various systems and instruments to cut and machine ultra-hard materials! However, among all those available devices and instruments; two which have gained utmost prominence in cutting nonferrous materials and substances have caught millions of eyeballs are CVDTools and PCD Tools.

There are various kinds of other tools like CBN Insert with Chip Breaker and PCBN Inserts for milling, machining, and Turning Graphite and other nonferrous materials. But CVD and PCD tools have proven to be more efficient and cost-effective than any other available devices in the market for ultra-hard material cutting. PCD tools are long-standing in this domain while CVD tools are greenhorn to the market. Both devices for diamond tooling are suitable for various nonferrous and sharp applications and material machining. But in comparison to the older version; the newcomer has proven to be more resourceful, competent, sheltered, and gainful for cutting, machining, and grinding of the diamond.

Why PCD Tools? / Warum PKD-Werkzeuge?

●      No matter if you are buying a PCD Insert or a PCD insert with chip breaker; PCD offers multiple advantages to the manufacturing operations of ultra-hard materials like diamond and Graphite Turning and milling. Even though diamond is the strongest and hardest material to cut, the material property of the PCD tools i.e. its strength and toughness are helping it to precisely machining the super-strong materials. The presence of sapphire in the microstructure together with the haphazard course of the diamond particles contributes to the improved toughness of this device a lot.

●    Moreover, the tungsten carbide substrate also backs up the mechanical division for cutting the abrasive coating of diamond, which eventually increases the impact confrontation of the device. Another benefit of PCD instruments is their availability to cut and machine a range of diamond grades suitable for any nonferrous applications. Basically saying, these instruments are ideal for cutting all these fine-grain, medium-grain, and coarse-grain diamond.

Why CVD Tools?/ Warum CVD-Werkzeuge?

●     The primary advantage of CVD Tools over PCD is their continuous cutting edge. No matter if it is polycrystalline or solid diamond without any cobalt binder, CVD devices can be employed for cutting and shaping diamonds with flawless finishing. These tools do not get hot and tempered and this is the reason why machinists prefer CVD tools over PCD devices for cutting at higher speeds for better finishes.

●     Moreover, CVDs’ thermal conductivity is more than 50% higher than the traditional tool which instantly conducts temperature away, making the application smoother, secure, and easy. CVD is also renowned for its low coefficient of resistance. With these devices, materials do not glue and its stumpy coefficient of abrasion allows these kinds of diamond tools to take towering chip loads which make the applications faster and more efficient.
