In the final PCB shaping stage—Routing—manufacturers often face a paradox: reducing speeds to maintain tolerances or increasing output at the risk of higher scrap rates. When processing abrasive materials like M9, High-Tg resins, and ceramic substrates, standard tungsten carbide (WC) routers often fail within meters, driving up the cost-per-part significantly.
Tiansheng Hengzuan (TSHZ) delivers the solution with CVD Diamond Coated Routers, utilizing atomic-level “armor” to break through these efficiency barriers.
1、Dimensional Accuracy Drift: Carbide is limited. When milling abrasive boards, the diameter shrinks rapidly. Once the wear exceeds 25um, the profile of an expensive HDI board is compromised.
2、Edge Integrity Crisis: Duller tools cause “compression” rather than “shearing,” leading to resin micro-cracks, fiber protrusion, or chipping—defects that are intolerable in automotive and aerospace electronics.
3、Downtime Inflation: Frequent tool changes waste spindle hours. Every calibration and test-cut adds non-productive overhead that eats into your margins.
Our CVD coating features a hardness of HV10000.
Standard FR-4: Lasts 3-5 times longer than carbide.
High-Hardness Materials (M9/High-Tg): Extends life by 5-20 times.
This allows you to plan production by “shifts” rather than “hours,” maximizing operational continuity.
At ultra-high speeds of 80,000 to 180,000 RPM, balance is everything.
Engineering: TSHZ uses customized dynamic balancing to ensure slot width tolerances remain within ±0.003mm.
Quality: Mirror-smooth routing surfaces with zero burrs, perfectly suited for high-density interconnect (HDI) requirements.
Diamond’s superior thermal conductivity combined with a low friction coefficient (< 0.1) rapidly dissipates heat.
Feed Rate: Supports 20%-30% faster feed rates.
Yield: Inhibits built-up edges, increasing total yield by 5%-15% and eliminating the fear of sudden tool breakage.
Material: Thick Copper / Ceramic Base (High Difficulty).
Old Method: High-end carbide routers; Life approx. 15m; Edge chipping rate 3%.
TSHZ Solution: CVD Diamond Coated Routers.
Outcome: Service life exceeded 200m; Yield reached 99.8%; Total processing cost per unit dropped by 48%.
Manufacturing competition is the competition of tool leverage. Tiansheng Hengzuan (TSHZ) diamond routers are more than tools; they are the strategy to boost machine utilization and reduce setup costs.

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.
