A double-sided grinder is an efficient and economical grinding machine made up of two rotating blades. A single-sided rotating blade is known as a single-edge blade, and its rotation is also clockwise or anti-clockwise. The first spinning blade is usually referred to as the fixed blade. The other spinning blade is called a variable blade, and it contains an auger or diamond attachment for boring or polishing objects. When both blades are spun simultaneously, they create a symmetrical pattern, known as an interrupted oscillation pattern.
Double-sided grinders are designed for two different workpieces. Typically, there is a smaller workpiece on the top surface of the grinder’s rotating disc, while the larger workpiece lies on the grinding disk’s bottom. The smaller workpiece is held in place by a pinion and rack system; the larger workpiece is supported by a pinion and deck system. The two discs can be aligned by means of a cam mechanism or a fixed wedge that aligns them both, or a hydraulic system that rotates each disc independently. The result is a symmetrical and effective grinding operation.
The two-sided grinder has the advantage of being faster than single-sided grinders. Its operation is simple: it starts by turning the grinding disk’s large disc vertically in the direction of rotation. This causes the grinding teeth to make a complete revolution, or flip, at the same time, creating a grinding contact. An efficient two-sided grinder has a fast revolution speed and produces excellent results, but is more difficult to manually control. On the other hand, a two-sided grinder that has a fast rotation speed and is well-controlled is a good choice for producing fine finishes in metal working.
The advantage of using a double-sided grinder lies in its ability to work on several different materials. The use of two different sized discs makes it possible to work on copper, tin, steel alloy, brass, bronze, magnesium, and many others. The use of these different materials provides the user with the opportunity to vary the depth and angle of grind in order to obtain different outcomes. It is also possible to use the grinding of two different discs in conjunction to increase the complexity of the grinding operation. For example, the use of a two-sided grinder along with a blade grinder at the same time can produce a two-sided finish in a relatively short period of time. These types of machines can even be programmed to return to the original grinding position automatically when the discs are replaced.
With the latest technology and its ability to work with many different materials, the double-sided grinder has proven popular among craftspersons and operators. Many have experienced firsthand the ease and satisfaction gained from using a this type of machine. They can use the machine to quickly grind decorative pieces, fine stones and tiles, curved patterns and contours, metals, plastic and other workpieces. Users have found the convenience and control of the machine to be unmatched. The ability to control the depth and angle of the abrasive, the speed and pressure of the motor and the angle of the grinding blade provide endless possibilities.
In the field of construction and other occupation that require hard surfaces to be worked on, there are few tools more useful and appropriate than the latest models of machines such as the FDT Gantry Disc Grinders. The durability and quality of the product allow users to turn back to old ways of life and perform the tedious tasks of their past. By combining the functionality of both disc grinder blades and a blade grinder into one single machine, the Gantry Disc Grinders delivers precision results in a fast and efficient manner. With designs that mirror that of their blade counterparts, these machines work to precision every time. These machines are designed to give craftsmen the power and control they need to turn out professional-looking results in short order.
