Rubber Roller grinding wheels for elastomers & polymers
Rubberhog® rubber roller grinding wheels are engineered for grinding, resurfacing, and finishing rubber, polyurethane, and other elastomer materials. Built with brazed tungsten-carbide cutting teeth, they deliver faster stock removal, longer service life, and consistent finishes.
Rubberhog wheels outperform conventional abrasive roll grinding wheels due to their unique construction. Each wheel is manufactured from a precision-machined steel core and fitted with long-wearing, brazed tungsten-carbide cutting structures that mechanically cut elastomers rather than relying on abrasive friction.
This cutting action helps reduce heat and smoke while improving process stability during roll grinding. Most Rubberhog wheels are supplied pre-dressed to maintain rapid material removal while producing smooth, consistent finishes on elastomer materials. In many applications, Rubberhog wheels deliver service life measured in multiples of conventional abrasives, reducing downtime and overall operating cost.
Roll Grinding Applications
One of the key advantages of Rubberhog roll grinding wheels is the wide range of available tooth styles and coarseness options. This allows each wheel to be closely matched to the specific elastomer material, grinding method, and surface finish requirement.
Rubberhog wheels utilize sharp, precisely formed tungsten-carbide teeth designed to penetrate rubber efficiently while maintaining open chip flow. This action behaves more like a milling process than conventional abrasive grinding, allowing rapid material removal without excessive friction or loading.
Despite their aggressive cutting capability, the uniform height and geometry of the teeth help produce smooth, controlled finishes on rubber and elastomer surfaces.
Excellent Rubberhog Applications Include:
- Rubber & Polyurethane Roller Coverings
- Lathe-Cut Seals
- Specialty Belt Products
- Elastomeric or rigid polymer foam products
Wheel Styles
Rubberhog roll grinding wheels for cylindrical traverse grinding are available in multiple wheel styles to support roughing, finishing, and combined grinding operations on rubber, polyurethane, and other elastomer materials. Each style is defined by the arrangement of tooth styles and coarseness zones, allowing the wheel to be matched to material removal rate, surface finish, and traverse direction requirements.
Single Grit
Single-grit wheels feature one tooth style and coarseness across the wheel face. They are commonly used for finish grinding or light regrinding where consistent surface quality is the primary requirement.
Double Grit
Double-grit wheels combine coarser “hogging” teeth at the leading edge with finer teeth following behind, allowing rough and finish grinding in a single traverse pass.
Triple Grit
Triple-grit wheels extend this concept by incorporating multiple grades of coarseness and are capable of aggressive hogging in either traverse direction, making them well suited for high-production roll grinding operations.
Grooving
Grooving wheels are designed for cutting narrow grooves, convex forms, and complex profiles in rubber and elastomer rolls where precise geometry control is required.
tooth styles
Rubberhog roll grinding wheels are available with multiple tooth styles and coarseness options to control cutting aggressiveness, heat generation, and surface finish when grinding rubber and elastomer materials.
Rubberhog Original SSG
The Original SSG tooth style features randomly positioned carbide teeth, which helps reduce tracking and patterning while producing smooth, consistent finishes on critical rubber roll surfaces.
Rubberhog Extreme MCM
The Extreme MCM tooth style uses a more open tooth arrangement to improve chip flow, reduce heat and smoke, and lower power consumption during aggressive roll grinding operations.
Rubberhog Crushed
Crushed coarseness options are commonly used for very narrow grooves, convex shapes, and complex roll profiles where controlled material removal and fine detail are required.
Accessories
High Performance Peeler Tools
Rubberhog high-performance peeler tools are designed to efficiently machine rubber and other elastomers, providing fast, controlled removal of large amounts of material without excessive heat or smoke. They are robust, simple to use, and built for long service life in demanding environments.
The system consists of a tool-post holder and replaceable, indexable peeler inserts. The tool-post holder accepts either insert style and fits a standard lathe tool post.
Rubberhog peeler inserts feature a wear-resistant tungsten-carbide coating that contributes to extended service life and a self-sharpening effect. As inserts wear, they can be indexed by rotating in the holder to expose multiple fresh, sharp cutting edges—maximizing usable life and reducing downtime.
- Rapidly strip old rubber from cores
- Save time by machining off overbuild
- Remove rubber quickly without heat or smoke
- Robust, simple to use, and long-lasting
Two insert designs are available to optimize performance depending on the application:
-
CCI inserts feature a zero-degree relief angle for increased impact resistance
-
TTI inserts feature a ten-degree relief angle for higher cutting efficiency
Rubberhog Dressing Kits
Unless otherwise specified, Rubberhog wheels are supplied pre-dressed to provide smooth, consistent results in use. For certain critical-finish applications, light dressing after mounting may be helpful to correct minor centering error or spindle runout.
Dressing is typically performed using a green silicon-carbide vitrified wheel, lightly contacting the tips of the highest teeth. Only a very small amount of material is removed—generally no more than 0.001 in (0.025 mm).
In many cases, minor surface marking observed during initial use resolves naturally after a short break-in period, without the need for dressing.
Trusted Worldwide for the Best Results
Rubberhog roll grinding wheels are trusted by manufacturers worldwide for consistent performance, controlled finishes, and long service life across a wide range of elastomer applications.
