Honing of Cutting Tool Edges
Processing Details
- Scraping
Controls the cutting edge shape of the cutting tool with a high accuracy of ±5%.
Honing cutting tool edges using wet blasting is a highly accurate and consistent process, enabling the manufacture of high-added-value cutting tools.
Cutting tool edge honing with wet blasting
Burrs that occur on the cutting edge during the manufacturing of cutting tools (inserts, etc.) are removed by wet blasting, and by giving the cutting edge a radius (cutting edge honing), chipping is prevented. This enables stable production of high-quality products with a long life and no variations. At the same time, this process is also effective in improving the adhesion strength of the coating on the cutting edge.
Another feature of our equipment is the easy control of K value (cutting edge shape).
Processing Points
- The cutting tool life can be extended up to 3 times by adding a radius to the cutting edge.
- Complex shapes can also be processed uniformly.
- K value (A/B ratio) can be controlled from 1.0 to 2.0 by controlling the rake face and flank face R ratios.
- High-precision processing of ±5% is possible with fine abrasives
Problems with press forming of cutting tools
- Burrs occur in the gap between the dies.
- The coating peels off from the tip of the cutting edge.
- The cutting edge radius varies after honing.

After Press Molding
Press molding produces burrs in the gap between the dies.
Untreated
Burrs increase the chance of the edges chipping and breaking.
After Wet Blasting
By removing burrs from the cutting edge and adding a radius, chipping is prevented. This enables uniform coating all the way to the tip of the cutting edge, thereby extending the tool life.
