High-Performance Metal-Ceramic Reamers

Why choose WangDefu High-Performance Metal-Ceramic Reamers?

Tough & Wear-Resistant Composite Material

Made from TiC/TiN ceramic phases bonded with Ni-Co metal, sintered under high-temperature powder metallurgy.

Hardness up to HRA93, 30% more wear-resistant than conventional carbide, with bend strength ≥3200MPa.

Ideal for interrupted holes, angled holes, and long overhang conditions, maintaining hole straightness <0.01mm/100mm.

Low Affinity & Coating-Free Cutting

Extremely low chemical affinity with ferrous metals, friction coefficient ~0.1.

Prevents sticking and built-up edge when machining stainless steel or titanium.

Can be re-sharpened repeatedly without losing precision, extending tool life 3-5x longer than standard carbide reamers.

Precision Geometry & Optimized Flutes

Five-axis precision ground cutting edges, edge radius ≤0.003mm.

6–12 blades evenly spaced, reducing vibration by 50%.

Supports straight flutes (through holes) and spiral flutes (15°–30°, blind/deep holes).

Maximum deep-hole ratio L/D up to 8D without clogging.

High-Temperature Stability & High-Speed Cutting

Retains hardness and strength up to 1000°C, ideal for high-speed operations.

Optional high-pressure internal coolant (20–30MPa) for precision cooling and chip removal.

Speeds 20–50% higher than traditional carbide reamers, especially for hardened steel and superalloys.

Technical Specifications

Applications

Automotive Manufacturing:

Reaming precision bolt holes in stainless steel gearbox housings. For example: φ10mm 8-flute helical reamer, cutting speed 70m/min, feed rate 0.2mm/r, tolerance ±0.004mm, surface roughness Ra0.4μm.

Aerospace Components:

Titanium alloy landing gear bushing holes. The cermet material prevents work hardening; The Quality High-Performance Metal-Ceramic Reamers have a life exceeding 600 holes, four times that of standard carbide tools, increasing productivity by 30%.

Mold Industry:

SKD11 hardened steel guide post holes. A straight-edged 10-flute reamer completes the hole machining in one pass, with a coaxiality of 0.005mm, eliminating the need for subsequent polishing and reducing the machining cycle time by 50%.

Recommended Cutting Parameters

Note: Leave 0.08–0.15mm allowance before reaming; for blind holes, use right-hand spiral; ensure sufficient cutting fluid for high-speed operations.
