High-Rigidity Carbide Rods with Helix Spiral Holes for Deep Machining

Overview

The High-Rigidity Carbide Rods with Helix Spiral Holes are innovative solutions for deep hole machining and precision tooling applications. Engineered from micrograin tungsten carbide (1-3μm) with internal spiral coolant channels, these rods combine superior stiffness with efficient heat dissipation, enabling stable performance in challenging deep-hole operations.

Features

Unique Spiral Hole Design:

Helical coolant channels (30°-45° pitch) direct high-pressure fluid (100-200 bar) to the cutting edge, reducing temperatures by 40% compared to solid rods.

Uniform wall thickness (±0.02mm) ensures consistent rigidity along the entire length, critical for maintaining hole straightness in depths up to 1,000mm.

Premium Material Properties:

Ultra-fine carbide (92 HRA hardness) with cobalt binder (8%) provides excellent resistance to bending and torsional stress during high-torque operations.

Electroless nickel plating (5-8μm) on external surfaces enhances corrosion resistance for long-term storage and use in wet machining environments.

Precision Manufacturing:

Laser-drilled spiral holes with ±0.05mm positional accuracy, ensuring seamless integration with coolant systems in deep hole drills and boring bars.

Ground to tight dimensional tolerances (diameter ±0.005mm, straightness ±0.01mm/m), ideal for precision tool holders and guiding systems.

Application

Critical for deep hole and precision tooling applications:

Deep Hole Drilling: Core components in BTA and gun drilling systems, enabling stable coolant flow for long-depth holes in oil field equipment and hydraulic manifolds.

Precision Tooling: Mandrels and guiding rods in grinding machines and CNC lathes, ensuring axial stability for high-precision cylindrical grinding (≤0.001mm TIR).
