A double-sided grinder is a general term used to describe any type of grinding device whose dual side is used to grind material. In many cases, these types of machines are more commonly referred to by their interchangeable names – disc grinder machine. A double-sided grinder is often used in abrasive milling applications such as in jewelry craft gemstone grinding. Such machines are also quite popular in woodworking applications, particularly the cutting and drilling stages of woodturning and turning.
A double-sided grinder is usually a rotating machine consisting of a flat grinding face that rotates clockwise, and a stationary grinding face that rotate anticlockwise. Occasionally the flat grinding face will also include a bench top jig slot in its center, allowing for easy storage and transport. The first rotating, flat surface is commonly called a fixed face. The other surface, known as the variable face, is sometimes also called a milling face, for either grinding or milling actions. Some units can also include additional accessory tooling on both sides.
Most units will have a pair of cutting edges on the flat and variable faces of the grinding machine. These cutting edges can be manually turned in order to fully flatten a burr. The flat face of the unit will typically remain fixed while the variable face moves up and down. When a piece of stock is being ground at the same time as the grinding machine, it can benefit from a front-and-back burr alignment. This allows the same grinding action to be performed on both sides of the workpiece, greatly reducing operation time and providing greater accuracy. For high quality products, the back and front burr of the cutting edge should be synchronized.
The term “double-sided” describes a unique type of grinder. Unlike a typical two-sided grinder, a dual-sided grinder will have two opposing cutting edges on both sides of the workpieces, which are each precisely cut, but at different times. The two cutting edges of a dual-sided grinder can be used in conjunction with each other to achieve even more precision and accuracy.
The latest technology used in a double-sided grinder can often be found on the company’s website. In addition to a wide selection of cutting tools, computer software packages, and other hardware and accessories, many companies provide users with graphic controls for the control and display of grind results. Some popular graphic controls include LCD readouts, knobs, sliders, touchscreens, and LED indicator lights. A complete range of grinding attachments, including grinders and grind wheel accessories, may also be available from leading manufacturers. For even greater convenience, many users find that they can purchase their favorite attachments right online.
With so many styles, models, sizes, designs, and functions available in the line of grinders today, there is sure to be a model that is perfect for virtually every application. From extremely compact tabletop models to large, heavy industrial grinders, there are truly two-sided grinders that are right for every job. Whether you need a two-sided grinder to do general sanding, leveling, or polishing, or you need a two-sided grinder for precise surface preparation and exact milling, there is likely a machine that will fit your needs. You may even want to combine the use of two grinding wheels so that you can get both the power of a two-sided grinder and the accuracy of a one-sided grinder. The one-sided units are often used for delicate work such as fabricating metal, while two-sided units are often used for fine dust and powder-coating operations.
