United Abrasives is one of the industry-leading manufacturers of grinding wheels and cut-off disks in North America. With a plant on the eastern seaboard, and warehouses in Ontario, Canada and Utah, USA, United Abrasives grinding wheels set the standard for reliability and durability for the steel and metal working industry. In the same way that a carpenter relies on their circular saw as an essential part of their tool box, metal workers rely in grinding tools and metal cutting saws which cut, grind and shape metals used in construction and commercial building fabrication.
United Abrasives main manufacturing plant is located in North Windham, Conn. This state of the art manufacturing facility is over 400,000 square ft, and has the capacity to supply products to the entire North American market.
Silicon carbide grinding wheels are used throughout the metal working and commercial construction industry. Metal fabrication is both a science and art, and the iron and steel workers together with the plumbers and pipe fitters rely on metal grinding wheels to complete their tasks. While steel used in building construction is manufactured to specific guidelines, the individual pieces of steel often have to be custom ground on the job site, before they fit together perfectly. Additionally, even when the steel members are perfectly shaped, after they are welded together, the metal welds are cleaned up by grinding off any access, so that the joint is ready for the next steps in the construction process.
Silicon carbide grinding wheels are also manufactured to different degrees of hardness. Each wheel has a specific purpose, and depending on the application, one grinding wheel works better than another.
- Soft bond grinding wheels are designed for softer metals. The wheel is designed so that it doesn’t load up with metal as it’s used. Soft materials, like low carbon ferrous metals, will clog a standard grinding wheel and reduce its effectiveness. The Soft Bond wheel prevents the metal from building up on the grinding wheel’s cutting surface.
- General purpose cutting wheels are the work horse of the industry. Perfect for harder, high-carbon steels and pipes, general-purpose wheels balance their cutting ability with material hardness. These wheels are often used for the pipeline industry.
- Hard edge wheels wear more slowly, and are designed for even harder alloys and ferrous steel. Hard edge wheels are often used for cutting notches in existing metals, or final fitting structural steel on-site for custom welding applications. Metal workers replace hard edge grinding wheels much less frequently because of their improved durability.
Additionally, other specialty wheels are designed for concrete, and stainless steel work. Concrete is soft, and cuts quickly, so depending on the tool, concrete cutting blades are often made of stainless steel with diamond cutting edges. Concrete grinding wheels are designed to quickly clear the material without loading up with debris.
Stainless steel cutting wheels are some of the most expensive grinding wheels. Stainless steel’s extreme hardness demands that the grinding wheels be even harder. These grinding wheels are often used as a final surface preparation, or to remove burrs from cut lengths so the stainless steel can be fabricated smoothly.
