Cutting Tool Edge Prep & Coating Polishing – Process Technology
Bel Air provides advanced tool honing and polishing solutions for manufacturers and rebuilders of cutting tools. Using drag, wave, and stream finishing technologies, our systems are designed for edge preparation, edge radiusing, and coating polishing on carbide and high-speed steel tools such as drills, taps, end mills, inserts, and reamers. These automated processes ensure consistent edge geometry, improved surface integrity, longer tool life, and enhanced cutting performance.
Ensuring the geometry, quality, and condition of the cutting edge and flutes is critical for performance. Here’s how our advanced finishing processes help:
- Edge Honing: Introducing a precise edge radius—typically between .0002″ and .001″—minimizes stress points and improves coating adhesion. Honed edges resist chipping, enable smoother machining, and increase tool durability.
- Coating Polishing: Coating methods such as PVD and CVD often leave behind microscopic droplets that create friction and hinder chip flow. Polishing these coatings eliminates imperfections, enhances surface smoothness, and enables tools to run cooler and more efficiently at higher speeds.
