Weiler Abrasives, a leading producer of abrasives and power brushes for surface conditioning, has announced its new Fortis Mill Hot Roll grinding wheels and Cold Roll grinding wheels.
These high-performance wheels feature advanced ceramic grain technology and formulations designed to maximise productivity and profitability for hot and cold roll mill grinding applications.
“Productivity and roll quality are the two most critical factors for roll grinding facilities, and the new Fortis Mill wheels are engineered to deliver on both fronts,” said Inja Skrinjar, product manager. “By combining self-sharpening ceramic grain with our proprietary Ultralock retention technology, Weiler Abrasives has created a wheel that not only lasts longer but also aggressively grinds harder-to-process materials with greater consistency, for maximum roll life.”
The new Fortis Mill wheels address key challenges, primarily extending wheel life and increasing material removal rates (MRR), ultimately reducing operational costs for end users. Testing demonstrates that the wheels deliver up to 20% longer life and faster material removal rates compared to previous generations, drastically reducing the frequency of wheel changeovers and associated downtime. Mills can also partner with Weiler Abrasives for expertise and technical support, to help unlock their full potential.
The Fortis Mill ceramic wheels are an upgrade to Weiler Abrasives’ existing portfolio, incorporating innovative features that set a new standard for roll grinding:
- Upgraded ceramic grain: The advanced ceramic grain is designed to be self-sharpening. The grain continually fractures into sharp, aggressive cutting points throughout the grinding process. This leads to higher, more consistent material removal rates and shorter grinding cycles.
- Ultralock technology: A proprietary grain treatment technology enhances the retention of the abrasive grain within the bond system. This advanced bonding significantly contributes to the wheels’ durability, reducing consumable spend and changeovers.
- Improved G-Ratio: The new wheel formulation improves the G-ratio (the ratio of removed workpiece material volume to wheel volume consumed). A higher G-ratio signifies better value, delivering faster grinding with significantly less wear for increased efficiency.
The Fortis Mill wheels are available in formulations tailored to the distinct requirements of hot and cold rolling mills. For hot mill grinding, where substantial material must be removed and surface finish requirements are less stringent, the wheels use coarser grains for maximum MRR and efficiency on challenging materials. For cold mill grinding, where surface integrity is paramount, the wheels use finer grits to consistently deliver precision surface finishes, ensuring smooth, scratch-free surface roughness (Ra) as low as 0,05 while eliminating damaging surface defects like chatter marks or spirals.
