Good

Although a simple cylindrical grinding application, what makes roll grinding challenging is the volume of stock removed from rolls, which are difficult to grind. The length of the roll also provides a challenge for the wheel to retain its size and form during the traverse grinding process. Maintaining high grinding ratios/roll reduction values is crucial in these applications, as they have a direct effect on the overall cost and cycle time. CUMI Roll Grinding wheels combine the latest developments in resin bond technology along with a suitable grain combination to give the optimal balance between cutting action and wheel life without compromising on the quality parameters.

Product Description

CUMI Roll Grinding Wheel

The CUMI Roll Grinding Wheel – Steel Series is engineered for heavy-duty roll grinding in steel mills, forging units, and metal processing plants, where large roll diameters and long traverse lengths demand exceptional wheel strength. Its resin bond matrix and optimized abrasive blend deliver fast removal rates while preserving form accuracy, helping industries reduce downtime and improve turnaround time.

Features → Advantages → Benefits

Advanced resin bond system → provides stable grinding action under high loads → achieves repeatable accuracy across long production runs
Optimized grain blend for steel rolls → ensures cool grinding with minimal burn or chatter marks → results in superior surface finish ready for chrome-coating or polishing
High grinding ratio & roll reduction value → allows longer dressing intervals → significantly cuts production cost & cycle time
Size & form retention over long roll lengths → maintains traverse accuracy → reduces wastage and rework time
Built for continuous steel-mill operation → withstands heat, pressure & vibration → offers maximum wheel life for industrial ROI

Industry

Used in steel rolling mills, hot/cold strip mills, forged roll manufacturers, heavy fabrication plants, & industrial roller refurbishing units.

FAQs

01.

Is this Roll Grinding wheel suitable for hot-rolled and cold-rolled steel rolls? Yes — it is engineered for both hot strip and cold strip mill steel rolls.

02.

Does it maintain form during long traverse grinding? Yes — the resin bond and structure are optimized for long-length grinding without losing profile.

03.

How does Roll Grinding Wheel reduce production costs? High grinding ratio and slower wear lead to longer intervals between dressing → reducing cycle time & power consumption

04.

Can Roll Grinding Wheel prevent burn marks while grinding steel rolls? Yes — formulation ensures cool cutting, minimizing heat buildup & metallurgical distortion.

05.

Is Roll Grinding Wheel suitable for wheel re-profiling applications? Yes — it works for roughing, semi-finishing, and finishing of industrial rolls.
