If you enjoy woodwork and own many tools, then you must know the usefulness of a grinder. A grinder can be used for many different things. It can be used for grinding, shaping, and sharpening. It all depends on the shape and wheels of the grinder. The wheels and shape of the grinder determine what kind of function the grinder will be performing.
How to Choose a Grinder
To get the best performance, you must know what type of grinder you need. When you know the type of work you need from the grinder, you can start looking for the most suitable one. Modern bench grinders often have two wheels on either end of the tool body. Each disc consists of different abrasives. These abrasives clean, polish, and sharpen chisels, turning tools, and planning knives. A quality bench grinder has adjustable speed settings. This function can adjust the revolutions per minute to match the wheel’s speed. It would be best not to exceed the wheel’s speed, as it can explode and destroy the wheel and grinder. In addition, they are injured or killed by fragments of broken wheels.
Before you choose a grinder, you must know what characteristics it should and should not have. Here are some of the characteristics that it should have;
- Accessible Switch
- Substantial guards around the wheels
- Flaps above the wheels
- The good mounting arrangement of the guards
- Should have metal spark guards
- Powerful motor
- Proper width of wheels
- Easy to change wheels
A good bench grinder should have an easily accessible, dust-tight on-and-off switch, a sturdy guard around the wheel, and a clear flap over the wheel. The best way to install these guards is to thread a few screws through the clear plastic top. You can easily replace them with offcuts from your double-glazed supplier, preferably strong polycarbonate. If the flap is dirty, consider raising it to see better what is unsafe. You also need a metal spark arrestor that can be adjusted to close the opening above each wheel as the wheels wear. A 300-watt motor is powerful enough, but some mill motors are designed for something other than continuous use. This should only be a concern if you plan to do much sanding, but if possible, choose a machine with a more reliable constant load motor. The next thing is to measure the width of the wheels. Some cheap grinders have only sixteen-millimeter-wide wheels. If you try installing a wider wheel, it may not fit because the threads on the motor shaft need longer. Wheels must be easily replaceable. Make sure there is enough room inside the fender if you install a wider wheel. Flanges are large washers that clamp each side of the wheel. Ideally, these should be milled from solid metal, not pressed. This makes it easier to assemble a precise wheel.
