Purpose of Cutting Tool Edge Honing & Polishing

1. Extend the service life of cutting tools
2. Improve the overall machining efficiency of machine tools
3. Reduce surface roughness of machined workpieces

Main Effects of Cutting Tool Edge Honing

1. Edge uniform rounding: Remove tiny burrs on tool cutting edges, realize precise and consistent edge radius treatment.
2. Eliminate defects of original sharp edges: Unprocessed sharp edges with micro burrs accelerate abnormal tool wear and scratch workpiece surfaces, resulting in poor surface finish.
3. Core benefits after edge honing: Smooth cutting edges effectively prevent edge chipping and tool breakage, greatly improve workpiece surface finish, and omit secondary finishing procedures.

Polishing Treatment for Chip Flutes

1. Uniform polishing on tool flutes improves surface quality and chip evacuation performance.
2. Smoother flute surfaces deliver superior chip removal and enable higher cutting speeds. Meanwhile, upgraded surface finish reduces the risk of seizure between the tool and workpiece material, cuts cutting force by 40%, and ensures much smoother cutting process.

Tool Edge Honing & Polishing Methods

1. Brush honing
2. Sandblasting
3. Drag finishing machine

Brush honing and drag finishing are the two most widely adopted solutions in the industry.
