A double-sided grinder, also known as a double-sided blade grinder, is a small grinding device consisting of two rotating blades that rotate anticlockwise and clockwise respectively. The first spinning blade is usually referred to as the fixed blade. This blade is secured in place by a set screw. The other blade, the rotating blade, is unscrewed and then placed in a bearing housing to be secured into place. The fixed blade is often made with a solid billet of aluminum or stainless steel, while the rotating blade is typically made out of plastic or rubber.
The most common use for a double-sided grinder in a professional grinder setting is when a piece of work needs to be ground into a rough surface without scratching the surface underneath. With a chuck alone, the only way to accomplish this is by physically turning the grinding wheel during the grinding process. By contrast, the rotary bar and fixed blade combination allow a smooth rotary action on the workpiece while also providing a non-scratched surface to the grinding tool. Grinding machines with this kind of design are often used by jewelry craftspersons who need to grind beads and other similar items into smooth finishes.
Another use for the double-sided grinder in a craftsperson’s workshop is when one blade is fitted with a chuck tool and the other blade is attached to the grinding stone. The purpose of these “cedar” grinding tools is to grind long and wide strips of hard wood or metal. By using both the chuck and the stone at once, the angle of the grinding stone and the blade can be precisely set for the task at hand. When using a chuck, it is important to remember to always start on the opposite side of the piece of wood or metal being ground. When the grinding blade is attached to the stone, the two blades meet over a stationary plane that ensures a consistent, even cutting plane throughout the entire length of the material being ground.
Grinding wheels are the most common type of cutter used in a two-sided grind. Although there are now a variety of hand held devices that can perform the same function, the burrs that these grinders leave on the surface of the material are much smaller than those left by a belt grind. This makes it more difficult to grind different types of metals as the burrs do not become very large. However, the convenience of a hand held grinder combined with its ability to grind different types of metals in a consistent manner makes these types of grinders popular with artists and other individuals who need to grind certain materials without the use of their machines.
Home grinders have the advantage of allowing users to grind softer metals such as copper and brass. A two-sided grinder will usually be able to grind softer metals to a depth of one-fourth the distance between the blades. Two grinders on a stand can provide a consistent grind for up to thirty minutes without interrupting the work going on. This type of milling machine is usually used to quickly grind alloy steel, aluminum, copper, brass, stainless steel, and the like. It is also capable of grinding aluminum, tin, magnesium, tinplate, lead, and several other alloys at high heat levels.
There are two main types of grinders that are available. The most common type is the two sided grinders while the two wheel grinders are designed to make even vertical cuts across many surfaces. These two types of grinders are useful for different types of jobs. They are also very affordable.
