CNC Solid carbide end mill

Description

1. Product Overview

CNC solid carbide end mill — a precision-engineered cutting tool manufactured from high-purity tungsten carbide with advanced micrograin structure and optimized coating options. Designed for high-speed milling, slotting, profiling, and finishing of ferrous and non-ferrous alloys, stainless steels, and hardened materials in CNC machining centers. It delivers superior tool life, consistent dimensional accuracy, and high metal removal rates, reducing cycle time and total cost of ownership. Strategically important for manufacturers seeking predictable machining performance, process standardization, and lower downtime across aerospace, automotive, mold & die, and high-precision industrial supply chains.

2. Key Specifications & Technical Characteristics

• Base material: Solid tungsten carbide (WC) with cobalt (Co) binder.

• Grain structure: Micro- to sub-micron grade for enhanced toughness and wear resistance.

• Typical composition: WC 88–95% / Co 5–12% (application-specific grades available).

• Hardness: Typical HRA 89–93 (depending on grade and heat treatment).

• Coating options: Uncoated; TiAlN (titanium aluminum nitride); AlTiN; DLC (diamond-like carbon) for non-ferrous; PVD/CVD variants available.

• Flute configurations: 2‑flute and 4‑flute variants; corner radius, square, ball-nose geometries.

• Cutting diameters: Standard range 0.5 mm to 25 mm (custom diameters on request).

• Lengths: Standard overall lengths (OAL) and cutting lengths (CL) per DIN/ISO tooling standards; custom lengths available.

• Surface finish: Precision-ground flute geometry, tolerance to DIN/ISO H7/H8 class as specified.

• Runout tolerance: ≤ 0.005 mm (application-dependent).

• Thermal stability: High thermal conductivity for stable cutting at elevated spindle speeds.

• Density: Typical bulk density ~14.8–15.6 g/cm³ (grade-dependent).

• Packaging options: Individual protective tubes; bulk in labeled boxes of 10/25/50; custom OEM blister packs or bulk wooden crates for pallet shipments.

• Shelf life: Indefinite under normal storage; store dry and protected from mechanical damage.

• Traceability: Batch lot numbers, material certificates (COA), and hardness reports provided with shipment.

• Compliance: Manufactured to ISO 9001 quality-managed process; RoHS-compliant components and packaging upon request.

3. Core Industrial Applications

• Aerospace: Precision milling of hardened titanium alloys, high-strength aluminum alloys, and stainless steels for structural components and complex airframe parts. Ensures tight tolerances, low burr formation, and long tool life in repeated, high-value runs.

• Automotive & Powertrain: High-speed slotting and profiling of transmission components, cylinder heads, and molds, improving cycle times and reducing per-part tooling cost.

• Mold & Die: Fine finishing and roughing of hardened tool steels and pre-hardened molds; superior edge retention reduces rework and polishing.

• Medical Device Manufacturing: Micro-milling and finishing of surgical components and implants from stainless steel and cobalt-chrome alloys requiring high surface quality and dimensional control.

• General Precision Engineering: Prototype and production machining of complex parts where high feed rates, surface finish, and repeatability are critical.
  Why it outperforms alternatives: Carbide’s superior hardness and wear resistance sustain higher cutting speeds than high-speed steel (HSS), while advanced coatings (TiAlN/AlTiN/DLC) extend life in abrasive and high-temperature cutting conditions. Micrograin carbide grades improve toughness vs coarse-grain alternatives, reducing chipping and downtime. Net effect: greater throughput, fewer tool changes, and lower cost per part.

4. Competitive Advantages

• Quality consistency: Tight tolerances, precision grinding, and ISO 9001-controlled production ensure repeatable geometry and predictable tool life.

• Supply reliability: Planned production capacity and buffer stock aligned to contractual forecasts; batch traceability and expedited replenishment options.

• Logistics capability: Packaging and palletization optimized for international freight; experience with air, LCL, FCL shipments and customs documentation for rapid cross-border delivery.

• Price competitiveness: Multiple grade and coating options enable value-tiered sourcing—cost-effective uncoated grades for high-volume roughing and premium coated grades for long-life finishing operations.

• Sustainability: RoHS-compliant components, reduced waste through extended tool life, and recyclable packaging options available for large contracts.

• Technical support: Application engineering services (recommended feeds/speeds, toolpath strategies), machining trial support, and full documentation (COA, material certificates, machining data sheets) included for enterprise customers.

• Risk mitigation: Consistent lot testing, runout verification, and pre-shipment inspection reduce downtime and warranty exposure.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT.

• Loading capacity (MT per container): Approximate loading per container: 20-foot container up to 20 MT depending on packaging and palletization; 40-foot container up to 24–26 MT. Final values subject to packing configuration.

• Lead times: Standard lead time 4–8 weeks for production on bulk orders; expedited options available subject to surcharge.

• Documentation supplied: Commercial invoice, packing list, bill of lading, COA, material safety and technical data sheets, and traceability lot reports.

• Warranty & returns: Manufacturer warranty covering material and workmanship defects; return policy for verified manufacturing defects under agreed SLA.
