Runout Adjustable Flange Adapter

What is the Runout Adjustable Flange Adapter?

The Quality Runout Adjustable Flange Adapter is engineered for ultra-precision milling, boring, and reaming operations. Unlike traditional tool holders, it features a built-in micro-adjustment mechanism that allows radial diameter adjustments with accuracy up to 0.001mm, repeatability ≤0.002mm. The dual-contact design between the flange face and spindle taper provides exceptional rigidity and ensures machining stability even under heavy cutting or long overhang conditions. This advanced precision tool is ideal for aerospace, precision molds, 3C electronics, and medical device manufacturing.

Core Advantages

1. Micron-Level Adjustment – Effortless Error Compensation

Equipped with an eccentric adjustment ring and precision set screw, users can adjust the clamping diameter within 0.001mm precision.

Adjustment range: 0.05–0.15mm.

Compensates for tool wear, spindle runout, and machining errors, maintaining workpiece tolerances within ±0.002mm.

Adjustment can be done without removing the tool, reducing trial cuts and scrap rates.

2. Dual-Contact & High-Strength Body

Made from 20CrNi2Mo high-strength alloy steel, forged and treated with vacuum quenching + deep cold process, hardness 60±2HRC, bending strength ≥1200MPa.

Dual-contact design increases contact area by 50%, improving torque transfer by 30% compared to traditional single-taper holders.

Radial runout remains ≤0.003mm even in high-load conditions, ensuring surface finish quality and avoiding chatter marks.

3. High-Speed Stability

Lightweight flange design minimizes centrifugal vibration and air resistance, maintaining dimensional accuracy for thin-wall or micro components.

Technical Specifications

Typical Application Scenarios

● Aerospace: Turbine blades, engine combustion chamber precision holes; zero-gap clamping ensures ±0.003mm tolerance, high rigidity prevents tool chatter.

● Precision Mold Manufacturing: Optical lens molds, semiconductor packaging mold cavities; micrometer-level accuracy allows Ra0.05μm surface finish without polishing.

● 3C Electronics: Micro-holes in smartphone chip slots, camera modules; stable high-speed performance reduces miniature tool breakage, achieving 99.9% dimensional consistency.

● Medical Devices: Orthopedic screws, dental implants; uniform clamping using the Runout Adjustable Flange Adapter prevents deformation, meeting ISO standards for implant safety.
