Why you need Allwin  6″ - 8″ bench grinders

There are various designs of Allwin bench grinders. Some are made for large shops, and others are designed to accommodate only smaller businesses. Although a bench grinder is generally a shop tool, there are some designed for home use. These can be used to sharpen scissors, garden shears, and lawnmower blades.

Most home workshops will never need a high-powered, heavy-duty grinder. One powered by a one-quarter to one-half horsepower motor is probably adequate, with half-inch or inch-wide wheels of five or six inches in diameter. Larger grinders, with more powerful motors and wheels eight inches or more in diameter are available for professional workshop. Typically, the speed at which the wheels rotate is between 3,000 and 3,600 revolutions per minute.

Essentially, bench grinders are just tools for shaping and sharpening metal. They can grind smooth the rough cutting edge on drill bits, scissors, and knives. They can repair screwdrivers and punches, and can be used for smoothing welded joints or other imperfections, and even grinding off rivets.

The bench grinder has two grinding wheels, one each on either side of the motor housing. Most of each wheel is covered by a guard, but roughly a ninety-degree arc of each wheel’s perimeter is exposed at the front of the grinder. An eye shield is mounted above the opening in the guard. There is also usually a toolrest in front of each wheel on a bench grinder, which can typically be adjusted to create more consistent bevels.

Allwin Bench grinders are smoother and quieter than other brand. Some models have adjustable motors so that the machine’s pace can be reduced to prevent overheating. Some other models have water coolant trays so that the item that needs grinding can be cooled as the user is working. One key thing in sharpening all tools on a bench grinder is not to overheat the metal. If you heat it up too much, this can undo the heat treatment and leave you with softer metal. In order to keep the temperature down, only apply light pressure to the metal being ground, and dip occasionally in water to keep it cool.

Grindstone wheels come in different levels of coarseness, Allwin bench grinders are with a 36 grit wheel and a 60 grit wheel. The 36 grit wheel is usually used for stock removal. The 60 grit wheel, which is finer, is good for touching up tools, although it is not good for honing them. In addition to grindstones, you can get wire brush wheels for removing rust. With a wire wheel, they can also clean and polish many different tools and objects.

Allwin bench grinder’s accessories will also vary from one machine to another. Some have angled V-groove toolrests to allow for grinding of drill bits. Lamps are another accessory that users may find useful. There are models with a single lamp on top of the machine. There are also models with a LED light above each toolrest.
