Solid Carbide Anti-knock Boring Bar

Key Features:
1. Anti-Knock Design
– Reinforced Core Structure: Optimized internal geometry (e.g., stepped or tapered profiles) dampens vibrations during interrupted cuts or deep-hole operations.
– High Rigidity: Solid carbide construction with transverse rupture strength (TRS) up to 5,500 MPa resists deflection, maintaining dimensional accuracy in long overhangs.

2. Material Excellence
– Tungsten Carbide Substrate: Ultra-fine grain structure (0.4–1.5 µm) ensures hardness of 1,800–2,200 HV for wear resistance in abrasive materials like hardened steels and Inconel.
– Cobalt Content: Adjustable Co binder (6–12%) balances toughness and edge retention.

3. Advanced Coatings
– PVD/CVD Coatings: Optional TiAlN, AlCrN, or DLC coatings reduce friction and thermal stress, enhancing performance in high-speed or dry machining.

4. Coolant Integration
– Through-Tool Coolant Channels: Efficient chip evacuation and heat dissipation in deep boring (up to 10× diameter depth).

5. Versatile Configurations
– Diameter Range: Ø3–25 mm (standard), with custom micro-boring options down to Ø0.6 mm.
– Shank Compatibility: Weldon, HSK, or BT shanks for seamless integration with CNC toolholders.

Benefits:
– Vibration Damping: Reduced chatter improves surface finish (Ra ≤ 0.8 µm) and tool life by up to 50% in unstable machining conditions.
– High Precision: Tight tolerances (±0.005 mm) for critical applications like turbine blade bores or medical implant cavities.
– Extended Reach: Anti-knock design enables stable performance in deep cavities (e.g., oil/gas tooling or aerospace components).
– **Multi-Material Compatibility: Effective in steel, stainless steel, titanium, composites, and hardened alloys (up to 65 HRC).

Available Options:
– Coating Variants: Custom coatings for high-temperature or corrosive environments.
– Geometry Customization: Asymmetric flutes, variable helix angles, or hybrid profiles for specialized tasks.
– Coolant Systems: Internal or external coolant delivery tailored to machine compatibility.

Quality Assurance:
– CNC Grinding: Precision-ground edges ensure concentricity ≤ 0.003 mm.
– ISO Certification: Manufactured under ISO 9001 standards with full material traceability.
– Dynamic Balancing: G1.0 or higher for vibration-free operation at high RPM.

Industry Applications:
– Aerospace: Boring cooling channels in turbine blades or CFRP components.
– Automotive: Machining engine cylinder blocks or EV battery housings.
– Medical: Precision boring for surgical instruments or implant bores.
– Energy: Deep-hole drilling in oil/gas tooling or hydraulic systems.
