The vertical grinder is a machine designed to grind small quantities of materials. The machine has two vertically positioned grinding stones that spin at the same time. These stones are referred to as “chips.” A vertical grinder is the ideal choice for rough-ground or rough-surfaced materials like concrete, limestone, rock, marble, soapstone, limestone, and other hardwoods.
The vertical grinder can be classified into three different types based on the amount of space they require. The first type is the light duty, or general purpose, machine. This type of grinder is suitable for general use because its size allows it to be stored in areas that are not frequently used for heavy-duty grinding applications. The second type is known as the heavy-duty grinding machine. It is built with larger and heavy-duty wheels and comes with more powerful motors.
The third type of vertical grinder is the portable one setup. This type of machine is compact, lightweight, and portable. It consists of one workpiece and is ideal for light duty workpieces. In addition to saving space, the portable one setup allows the user to move the workpiece from one location to another without interrupting the grind.
Because the vertical grinder utilizes a single workpiece for both the cutting and grinding operations, the quality of the work will always be higher than with any other type of machine. The cut quality and the angle of the workpiece when compared to a circular grinder allows for a smoother and cleaner finish. In addition, the angular contact surface of a vertical grinder provides a lower level of impingement and eliminates a large percentage of scrap during the grinding operation. These benefits provide users with a consistent level of quality and a consistently superior level of cut.
The last type of vertical grinder is the zero-tolerance vertical grinder. This is a completely enclosed machine. It has a lower level of impingement than most of the other types of vertical grinder and does not generate a large amount of scrap. Despite this benefit, the zero tolerance vertical grinder still has a lower level of roundness than most circular grinder models. Because of the close roundness of the workpiece, there is always a small loss in performance with this model.
Although the above three types of vertical grinder all use a single workpiece as the input into the grinding and cutting operations, the way the workpiece is held can have a significantly positive impact on the level of output and the quality of the finished product. The two workpiece styles that have the least amount of clamping force are the groundwork style and the zero-tolerance vertical grinder. These models allow for less distortion of the material by reducing the amount of travel that the material experiences during the grinding and cutting stages of the process. In addition, because the distance the material travels is relatively small, they also have the least amount of distortion and therefore produce very consistent results.
