Extra dlouhý výstružník pro zpracování leteckých dílů

Přehled produktu

Extended length reamers are specialized cutting tools designed for precision hole finishing in deep or hard-to-reach workpieces. These reamers feature an elongated shank and flute design, enabling accurate machining of holes with depth-to-diameter ratios exceeding 10:1. Manufactured from high-performance carbide or HSS materials, they maintain rigidity while achieving tight tolerances (IT6-IT8) and superior surface finishes (Ra 0.4-1.6μm).

Klíčové vlastnosti

1. Extended Reach Design

   • Shank lengths up to 1,500mm available

   • Optimized flute geometry prevents deflection during deep-hole machining

2. High-Performance Materials

   • Solid carbide for maximum rigidity and wear resistance

   • Cobalt-enriched HSS for tough materials like stainless steel

3. Precision Engineering

   • Ground cutting edges ensure ±0.01mm diameter tolerance

   • Helical or straight flute configurations for material-specific performance

4. Specialized Coatings

   • TiAlN or AlCrN coatings for heat resistance in continuous operation

Technické specifikace

• Rozsah průměrů: 3mm to 50mm

• Length Configurations: Standard (10xD), Extended (15-30xD), Custom (30xD+)

• Tolerance Grades: IT6 for precision fits, IT8 for general applications

• Surface Finish: Achieves Ra 0.4μm in most materials

Aplikace

• Aerospace: Fuel system components, hydraulic actuators

• Automobilový průmysl: Transmission shafts, cylinder liners

• Energie: Turbine blade cooling holes, heat exchanger tubes

• Lékařský: Surgical instrument bores, implant guide holes

Performance Advantages

Superior Straightness
Precision-ground pilot sections guide the tool through deep holes, maintaining straightness within 0.02mm per 100mm length.

Reduced Vibration
Variable pitch flute designs minimize harmonic vibration during operation, extending tool life.

Efficient Chip Evacuation
Wide flute channels combined with high-pressure coolant ports prevent chip packing in deep holes.

Operating Recommendations

• Speed: 15-50 m/min (carbide), 5-20 m/min (HSS)
