Harig Air-Flo 5C Collet End Mill Sharpening Fixture

Manufacturer: Harig | System: Air-Bearing | Collet Type: 5C

Professional Overview

The Harig Air-Flo is the industry standard for precision sharpening and reconditioning of end mills, reamers, and routers. By utilizing a high-precision air-bearing system, the spindle floats on a .0001" film of air, eliminating metal-to-metal contact and providing virtually frictionless movement. This "finger-sensitive" control allows operators to detect even the slightest resistance while grinding, ensuring superior surface finishes and accurate tool geometries on cutters as small as 1/32".

Technical Specifications

• Collet Capacity: Standard 5C collets (up to 1-1/16" diameter).
• Spindle Travel: 10" stroke on a hard chrome-plated and ground spindle.
• Indexing: Precisely spaced collars provide 2, 3, 4, or 6 indexes for end-tooth sharpening.
• Adjustment Range:
• Rotation: 360° graduated base.
• O.D. Clearance: Up to 20°.
• Tilt (End Teeth): 30° fore and aft.
• Air Requirements: Typically operates on 60–100 PSI (requires clean, dry air).
• Sensitivity: Capable of sharpening tools from 1/32" to 2-1/2" diameter.

Key Performance Features

• Frictionless Air-Bearing: The zero-friction design ensures that the operator only feels the grinding action, not the machine's own resistance, which is critical for consistent relief angles.
• Universal Versatility: Designed to sharpen all areas of a cutter, including the periphery (O.D.), end teeth, notches, flute faces, and corner chamfers.
• Precision Fine-Feed: Features a graduated micrometer thimble for instant, fine adjustment of the finger height to determine clearance angles with "tenths" accuracy.
• "Rocking" Action: The specialized rocker assembly allows the operator to quickly pull the tool away from the grinding wheel for rapid indexing between flutes.
• Modular Mounting: Includes a finely graduated swivel base that allows the fixture to be adapted to most tool and cutter grinders or surface grinders.
