FAQ’s On Knife And Cutlery Abrasives Manufacturing

Use high-performance zirconia or ceramic abrasives for a cooler cutting action. CUMI’s grinding belt and flap wheel belts and flap wheels minimize discoloration and preserve blade temper.

To achieve a true mirror finish on knife blades, follow a multi-stage polishing process:

  1. Start with fine-grit sanding – Use 400 to 800 grit ceramic belts or flap wheels to remove surface marks and create a uniform base.
  2. Intermediate polishing – Use non-woven abrasive wheels or buffing wheels to remove micro-scratches and begin the polishing phase. Keep RPM and angle consistent.
  3. Final polishing – Use soft cotton or buffing wheels with a suitable abrasive polishing compound (such as aluminum oxide-based pastes) to create a mirror-like finish without affecting the edge profile or temper.

CUMI offers specialized polishing wheels and compatible compounds tailored for stainless steel and forged blades—ensuring clarity, reflectivity.

Not ideally. Blade geometry, hardness, and edge sharpness requirements vary. CUMI offers application-specific solutions to maximize life and output for each product type.

Yes. Overheating during powered grinding is a well-known risk. Friction buildup at the edge can soften the blade’s temper and compromise edge retention.

How to avoid it:

  • Use cool-cut abrasives with ceramic grains and bond systems that dissipate heat effectively.
  • Incorporate water or mist cooling systems, especially when working with high-hardness stainless or modern powdered alloys.
  • Monitor machine speed and avoid prolonged contact in one spot.
  • Choose abrasive systems designed for controlled thermal load, like CUMI’s engineered belts and discs.

Over-pressuring an abrasive belt or disc not only accelerates wear but also degrades finish quality. This lowers tool life and causes edge inconsistencies.
