In the production of abrasive materials like graphite, ceramics, high-silicon aluminum alloys, and aerospace composites (CFRP), tool wear is the primary driver of runaway production costs. Tiansheng Hengzuan (TSHZ) utilizes advanced CVD (Chemical Vapor Deposition) technology to grow a layer of pure crystalline diamond on a carbide substrate at an atomic level—solving the most persistent bottlenecks in precision engineering.
Hardness is the ultimate metric for wear resistance. While standard tungsten carbide tools typically range between 1,600 and 2,000 HV, our CVD Diamond coating reaches a staggering 10,000HV.
Longevity Leap: Under identical conditions, TSHZ tools offer a service life 10 to 20 times longer than uncoated carbide.
The Logic: This extreme hardness allows the cutting edge to maintain its geometry even when cutting through highly abrasive glass or carbon fibers, virtually eliminating dimensional drift caused by tool degradation.
A coating is only as good as its adhesion. TSHZ ensures that every tool possesses superior physical characteristics through a meticulous non-standard customization process:
Atomic-Level Adhesion: Through precise cobalt-leaching pre-treatment, we create a powerful mechanical anchoring effect between the coating and the substrate. This ensures zero delamination even under high-load milling.
Thickness Uniformity: The coating thickness is strictly controlled within 10-15um. This uniformity minimizes radial run-out, guaranteeing a mirror-like surface finish on the workpiece.
Diamond is not just hard; it is naturally self-lubricating.
Anti-Sticking Properties: An ultra-low friction coefficient means there is almost zero adhesion between the chip and the tool face. This effectively inhibits the formation of Built-Up Edge (BUE), ensuring that chip flutes remain clear at all times.
Parameter Breakthrough: Our tools allow for a 20% increase in feed rates and higher spindle speeds. This shortens cycle times while reducing the thermal impact on the workpiece material.
TSHZ Diamond Coated tools are the versatile “workhorses” for difficult-to-machine materials:
Graphite Machining: Eliminates edge chipping and ensures continuous, unattended operation for mold electrodes.
Zirconia Ceramics (Dental): Ensures edge integrity for prosthetics, reducing material waste in medical labs.
Composites (CFRP/GFRP): Shears through fibers cleanly rather than tearing them, preventing delamination and fraying.
High-Silicon Aluminum: Prevents the chemical affinity of aluminum from “sticking” to the tool, a common nightmare in automotive part machining.
To translate this 10,000 HV hardness into actual profit, we recommend following these technical guidelines during operation:
| Parameter | Recommended Control | Technical Purpose |
| Spindle Run-out | ＜0.005mm | Protects the brittle coating from micro-chipping caused by vibration. |
| Cooling Method | High-pressure air or oil mist | Leverages diamond’s high thermal conductivity to dissipate heat rapidly. |
| Replacement Threshold | At 85% of estimated tool life | Ensures absolute dimensional consistency in high-precision runs. |
Tiansheng Hengzuan (TSHZ) is dedicated to providing more than just tools—we provide “Profitability Engines.” We don’t just manufacture; we optimize. If you are facing a specific material challenge, send us your technical drawings, and our engineering team will provide a tailored parameter optimization plan.
Graphite, Ceramics, and Carbon Fiber are the future, but they are “tool killers.” If you’re still using traditional coating, you’re fighting a losing battle.
Our CVD (Chemical Vapor Deposition) Diamond Coating creates a real crystalline diamond layer on the carbide substrate. This isn’t just a “finish”—it’s a shield.
Why top distributors choose our CVD series:
1.Ultra-Low Friction: Prevents chip welding and heat buildup.
2.Extreme Abrasion Resistance: Maintains sharp cutting edges $20 \times$ longer.
3.Surface Finish: Mirror-like results on the workpiece, zero secondary polishing needed.
