The Polishing Machine
After the purchase of a bridge saw, a medium-sized fabrication shop will usually consider an automatic edge polishing machine. They typically do the work of two or three employees using hand tools. Polishing machines come in two basic configurations: vertical and horizontal. Because most medium-sized shops average six to 10 employees working in a 370 to 740-sq. m. area, a vertical polishing machine is usually the best choice. It takes up less floor space than a horizontal machine. Also, because material is usually stored and handled vertically, the vertical machine reduces handling and the chance of breakage.
One type of polishing machine considered versatile is one that automatically polishes not only squared-off and inclined edges, but also toroidal edges and other convex shapes. As long as the edges to be polished have the same thickness, pieces can be inserted one after another. A conveyor belt carries them through a group of automatic mandrills that bear a series of abrasives ranging from the coarsest grain to a polishing abrasive.
Another type of machine to be considered is the flat edge polisher, sometimes called the back-splash polisher. Actually, it will also polish countertops of any size, length, and height. As its name implies, it will only polish flat surfaces, but it can also chamfer upper and lower edges if desired. These machines are fairly inexpensive and have a compact footprint to save floor space. The production rate for such a polisher is from 24 to 30 lineal meters per hour. Again, these types of machines will help speed production and increase your volume.
The water system
As production increases, water consumption increases as well. For a medium or large fabrication shop, a closed water system can pay for itself in a year or two. It recycles the water run through the machines to keep the leveling tools cool instead of dumping it into the sewer. It can also recycle water used in a dust booth. Beyond reducing the water bill, such a system also guarantees the rate of flow needed to meet the demand of the machines.
