A double-sided grinder is an innovative grinding device consisting of two rotating faces that rotate clockwise and a rotating face that rotates anticlockwise in the process of turning. The two faces are generally referred to as a stationary face and the adjustable face. There is considerable variation in the type of machines that are available for cutting and grinding using this method of operation. The various types of double-sided grinders are:
A single-sided, or single-side, double-sided grinder is the more traditional form of machine and is commonly found in the workshop. The basic design consists of two opposing rotating surfaces which, when used, create a unique pattern of movement by exposing different sides of the workpiece at equal incidence. The advantage of this design is that it enables the user to use the machine without affecting any of the working pieces. When the two grinding surfaces are turned at different angles, the result is a unique pattern of grinding operation which allows for the exact formation and elimination of minute ground errors. This style of machine is normally the most appropriate for producing fine lines of grain and has a reputation for being particularly effective on softer and finer sandpapers.
Two-sided grinders, which can also be termed a ‘dual-side’ grinder, consist of two opposing grinding surfaces which are in turn fitted with turning bars. The main advantage of this design is that it is ideal for use on a wide range of abrasives. As well as producing a fine finish on the workpiece, two-sided grinders can also be used to grind textured materials such as plaster, enamel and melamine. Two-sided grinders are especially popular with those who produce smaller hand tools for use in their profession. These machines enable workers to complete precision milling and polishing operations that would otherwise be impossible without the use of more powerful machinery.
A ‘one-sided’ grinder resembles the double-sided grinder in that both grinding surfaces are in use at the same time but they operate in opposite directions. This is the preferred design when using abrasives in applications where a greater amount of accuracy is required such as abrasive grinding in the shape of letters or other shapes. A one-sided grinder enables the user to grind different types of surfaces at the same time because one side of the machine is designed for working with one type of material, whilst the other side is designed for working with another.
With recent advancements in technology, new types of machines have been developed to suit ever-increasing demands. One of the most recent developments is the EDG-700, which is capable of delivering precision performance even during heavy workloads. The machine is made up from dual blade units which enable it to grind either along the top or bottom of the workpiece. The latest technology found in this machine is its ability to work in conjunction with the EDG-series chuck units which also incorporate built-in cooling systems. It also incorporates a fully programmable function which allows users to configure its settings and perform a number of tasks such as; grinding, polishing, tumbling, piercing, buffing, laminating, forging, etc.
These machines also come in different types including single blade and double blade grinders and are able to control speeds and feed rates individually. These types of grinders offer a wide range of benefits and advantages over other similar products in the market today. Most importantly, they produce consistent results that make them ideal for use by professional operators. They are also perfect for home users who want to provide their own form of home espresso. Whatever the application, one can always depend on these machines for precision performance and unmatched quality.
