The Difference Between A Router And A Surface Grinder
A flatwork grinding machine is basically a rotating tool (a burr grinder) used to cut and grind surfaces of all shapes and sizes. It is used most commonly to create a smooth finishing on flat surfaces such as metal or aluminum. It’s a commonly used rough, abrasive machining method where a spinning spindle containing a grinding wheel at the center is moved over a workpiece to chip away at small pieces of metal or non-metallic material from it. These are very popular because they can be programmed for different cutting requirements, such as a repetitive chopping operation or a repetitive drilling operation.
The main difference between the CNC grinders and other types of grinding tools is that these machines use a fixed grinding wheel and do not have the ability to bevel or beveled edges. This results in a steeper edge when the grinding wheel makes contact with the work surface. The result is a smoother edge than what could be attained with other types of tools. Because of this, these machines are better suited for precision work than other types of tools.
A CNC milling machine operates in much the same way as a table saw or a drill press in that it begins by spinning the grinding wheel at high speeds until it comes in contact with the work piece. The work then is moved to the far side of the spindle at which time the grinding wheel comes in contact with the work surface to grind away at the material. Unlike other types of grinding tools, the CNC machine allows the user to program the cutting points by which the cutting point on the opposite end of the grinding spindle will cause the grinding wheel to stop. This means that the user can set a level of speed and depth of grind. This allows the user to control the end result of the grinding operation.
The CNC milling machine is sometimes used in metalworking applications such as sanding, drilling, beading and other metal forming operations. In these instances, the machine does all of the work but leaves the operator to simply control the angle and the speed at which the tool is operating. If the user desires a specific type of finish, he or she can program the machine to perform the needed operation. For example, if the user wants to use a hardening process that binds the metal to the table, he or she can program the machine to operate at a specific angle. This allows the user to get a perfect finish on the object without having to spend hours polishing and finishing the piece.
Although a CNC milling machine operates much like a router, it is a little different in that the workpiece does not move at all during the operation of the grinding wheel. Rather, the user has a set of keys or levers to activate or deactivate the grinding device. If necessary, the operator can take the key or lever and switch the wheel off to prevent damage to the workpiece. Once the grinding wheel has been switched off, the operator may then hold the key or lever in his or her hand and rotate the grinding wheel back and forth.
One final distinction between a surface grinder and a router is how the device is powered. Unlike a router, the CNC milling machine is powered by the operator’s hands. Unlike with a router, though, the workpiece moves along the rail of the surface grinder. This movement generates friction against the workpiece. The friction causes tiny scratches in the surface of the workpiece. These small scratches, if left alone, can add up over time and make the piece look older, which is why the operator must use extreme caution when operating the surface grinder.
