Polycrystalline Diamond (PCD) Cutter Teeth

A: Carbide picks face extreme wear or catastrophic failure ("tips break off") when taking on that kind of abusive, high-hardness, high-quartz rock formation because the material cannot physically handle the blunt force trauma. DQ DIAMOND's PCD picks are designed to crack those "tough nuts." Equipped with 3mm ultra-coarse diamond grains and diamond micropowder (extremely high purity) inside the pick tip core, we push micro-hardness beyond 90 GPa. More importantly, we leverage our proprietary Ti-Si-C gradient transition layer technology to increase diamond-to-steel body bonding strength by 50% (up to 1.8 GPa). When under enormous impact load, not only will the pick refuse to delaminate/break off; it actually has a "step- wise self-sharpening" ("Gets sharper with use!") feature that eradicates tormenting headaches of tip chipping and lost production downtime.

A: When excavating at high speeds, frictional heat causes "thermal degradation" (graphitization) of the diamond. When the tool starts softening, you know excavation speed has plummeted. While many companies focus solely on materials science, DQ DIAMOND couples that with structural design based on principles of biomimicry and fluid dynamics. Using a biomimetic wedge- shaped tip combined with our asymmetric spiral profile, lateral force variation ("rocking") during operation can decrease by up to 40%. The cutter now experiences less resistance when cutting, allowing the machine to run smoother. Pair that with our optimized chip-clearing groove design, and you've increased cuttings evacuation efficiency by 60%. More cuttings cleared out of the way means less heat built up ("burning" of your diamond bit)! More efficient heat dissipation translates to a significant improvement in your single-shift advance rate, which is what you're really concerned about anyway.

A: Sometimes cutter failure is not because the diamond did not have enough wear resistance, but the cutter body just wore away first ("eroded away") due to high pressure muddy water, leaving the alloy tip hanging loose. To combat these extremely tough conditions (a perfect combination of cruel water-rich underground meets broken formations), we developed a brand-new dual- stage metal sealing system to prevent water erosion. We also implement laser-clad WC-10Co (tungsten carbide- cobalt) coating onto the cutter body surface. Think of it as "body armor" for your cutter. It increases cutter body's resistance to water erosion 3 fold. Now you can blast through those high pressure underground pipes without worrying about your tool falling out ("washing out") because it's stuck tight to the tungsten-carbide wedding ring we sealed it with, whether you're using PDC spherical cutters for trenching or ripping through water-rich hard rock deep underground.

A: Don't you worry-here at Deqin New Materials we never believe in "cookie-cutter" solutions; we tailor system solutions to your needs. We offer free-of-charge fully-customized designs according to your rock hardness, tunneling machine type, and operating intensity. Whether you need tools configured with a negative rake angle and $\Phi 14\text{mm}$ spherical cutter to crush through ultra-hard rock; or shock-resistant ("Engineered to withstand high G forces"), asymmetrical cutter profiles to navigate fractured formations, our tech team will walk you through three sets of custom designs for your selection during our collaboration process. Factories lead time? Stop right there. We are based in Zhengzhou (the center of the world's superhard materials industry), we have access to superior quality raw materials and technical support. All you have to do is send us the geological data from your site, and we can optimize your operational plan and have the custom-made product physically delivered to you within one to two weeks.

A: In engineering operations, we shouldn't just look at the unit price of a single bit; we need to consider the "total cost of ownership." Standard bits are cheap, but they need replacing every two or three days. This not only causes equipment downtime and project delays, but also forces crews to risk their safety by changing bits daily in deep shafts, at the tunnel face, or at great heights-driving up labor costs and safety risks. Switching to our PCD bits extends service life several times over. The frequency of bit changes drops drastically, allowing equipment to run efficiently 24/7 and significantly shortening the project schedule. More importantly, frontline workers no longer need to frequently perform manual bit changes in hazardous areas, ensuring greater safety. The savings on downtime, consumables, and labor far outweigh the initial price difference of the bits, ultimately leading to higher overall profits.
