Description

Compared with conventional abrasives, White Aluminum Oxide (WA) grinding wheels provide sharp cutting performance, excellent heat resistance, and stable grinding behavior. The vitrified bond structure ensures consistent cutting action, minimal wheel deformation, and reduced risk of overheating during grinding. This WA grinding wheel is designed for applications where surface quality, dimensional stability, and temperature control are critical.

Key Advantages

  • Sharp WA grains for efficient cutting and self-sharpening

  • High porosity for better chip removal and cooler grinding

  • Excellent form holding and dimensional stability

  • Heat resistance and chemical stability for consistent performance

Grit Size Options & Applications

30#–46#
For coarse sharpening and edge shaping

60#–80#
For general knife sharpening and tool grinding

100#–120#
For fine sharpening and edge refinement

W20 and above
For polishing and mirror finishing

Applications
