In precision cutting applications, blade performance is highly dependent on the condition of its cutting edges — wet blasting is rapidly becoming the industry standard for achieving controlled, repeatable cutting-edge preparation for bandsaw blades.
By combining compressed air, abrasive media, and water in a slurry, wet blasting enables manufacturers to accurately control critical parameters such as:
• Edge radius tolerance down to ±5 microns
• Slurry concentration and flow rate
• Blast media type and particle size
• Nozzle angle, standoff distance, and air/slurry pressure
This level of precision ensures consistent edge honing, reducing stress concentrations at the cutting edge, which lowers the risk of micro-chipping and improves heat dissipation during cutting operations.
With temperatures at the tooth tip often exceeding 1000°C, the ability to create a controlled edge geometry is vital for preventing thermal fatigue and premature tool failure.
Additionally, wet blasting eliminates the variability of manual ‘run-in’ processes, delivering blades with optimised edge geometry straight from production — improving tool life by up to 200% and enhancing operational uptime.
If your bandsaw blade brand relies on extended blade longevity, and achieving consistent edge performance, wet blasting deserves a place in your workflow.
