To cope with the surge in overseas orders, TianSheng HengZuan expanded its intelligent coating center located in Jiujiang, Jiangxi Province, doubling its annual production capacity by 2026. It has now become a key global supplier of graphite machining tools and high-silicon aluminum machining tools. While many competitors are still merely acting as intermediaries selling cutting tools, TianSheng HengZuan has already taken control of production capacity at the source. Owning manufacturing facilities grants bargaining power; scale delivers ultimate cost-effectiveness. This is why Fortune Global 500 manufacturing enterprises choose to procure directly from TianSheng HengZuan.

Frequently Asked Questions

"Price is what you pay, Cost is what you lose. A $15 tool that stops your $200k machine every 2 hours is the most expensive thing in your shop. Our CVD tool costs more because it buys you 40 hours of uninterrupted 'spindle-on' time. Which one saves you more by the end of the month?

I love skeptics—they usually become our best customers. In G5 Graphite or 18% Silicon Aluminum, standard carbide yields to abrasion in minutes. Our $8000 HV$ diamond crystalline layer literally ignores that abrasion. We don’t just claim it; we have the micro-wear test reports to back it up. Want to see the comparison video?

Stop right there. I’d love to sell you a tool, but Diamond and Iron are 'enemies' at high temperatures (chemical affinity). For steel, use our AlTiN series. But if you’re cutting Graphite, CFRP, or Ceramics, our CVD is the undisputed king. We sell solutions, not just metal.

That’s the difference between DLC (Diamond-Like Carbon) and True CVD. Most cheap 'diamond' tools are just thin films. Our CVD is chemically grown into the carbide substrate. It doesn't just sit on top; it's part of the tool. No peeling, just pure cutting.

Actually, it improves it. Because the diamond layer is ultra-smooth and the edge stays sharp 20x longer, you avoid the 'tearing' effect of a dull tool. You get a mirror-like finish on the 100th part just as you did on the 1st.

Don't sell them a tool; sell them 'Machine Capacity.' Tell your customers: 'Would you rather buy 1 tool and run all night, or buy 20 tools and pay someone to stand there and change them?' The labor savings alone pay for the tool.

"Diamond loves speed. High RPM is where it shines. We provide a customized cutting data sheet with every order. If you’re not sure, send us your material grade and we’ll calculate the optimal Vc and Fz for you. We don't just ship tools; we ship success."

We control coating thickness within $\pm 2\mu m$. In high-precision graphite electrode machining, we know microns matter. Our QC report for every batch ensures your offsets stay consistent from tool #1 to tool #100.

We stock standard sizes for immediate dispatch. We use DHL/FedEx—typically 4-7 days to your doorstep. We know a downed machine is a bleeding wound, and we’re here to stop the bleeding fast.

We offer 'Performance Guarantee' samples for qualified shops. We don't give them away for free because high-end tech has a cost, but if it doesn't outperform your current tool by at least 10X, the next one is on me. Fair enough?

Dental burs

Ultra-hard and wear-resistant for extended service life: High-strength, densely coated diamond layer significantly harder than conventional silicon carbide burs—resistant to wear, sand loss, and chipping, thereby doubling service life and reducing replacement costs.

Custom Profile

Truly cost-saving custom service

Diamond-coated cutting inserts

Diamond-coated cutting inserts are meticulously fabricated using cemented carbide substrates and high-performance diamond vacuum coating technology. The diamond crystals are densely and uniformly arranged with strong bonding strength, delivering exceptional hardness, outstanding wear resistance, low friction coefficient, high-temperature resistance, and impact resistance.

PCB Diamond-Coated Milling Cutters

PCB diamond-coated milling cutters, also known as PCB routing cutters, printed circuit board milling cutters, or engraving cutters, are primarily used for contour cutting, slotting, depth-controlled milling, V-grooving, half-hole machining, and gold finger chamfering of PCBs; they are the most commonly used carbide tools in post-PCB manufacturing processes.

Is your tooling keeping up with the "Difficult-to-Machine" era?

Leave A Message

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.
