An Aggressive Alternative to the Traditional Grill
Surface Grinder is used to create a smooth surface on flat surfaces. This is a popular, wide-spread industrial machining procedure where a rotating cylinder containing abrasive material (such as granite) is used to cut large chips of non-metallic or metallic material from a workpiece. The abrasive material used is usually referred to as ‘lateral abrasive’. Lateral abrasives spin around a cylindrical core comprising a rotating cage and rotating steel or bronze balls. The abrasive material is forced into a slot in the work piece, where it projects an edge of the same size on the opposite side of the work piece.
The main advantage of using the surface grinder is that it provides high-quality machined edges at a lower cost than machining other mechanisms such as hand-drilling or drilling holes in the workpiece. It also produces fine finishes on a larger area than hand-drilled or drilled holes, at a fraction of the cost. However, due to the complexity of the design and required functionality, the precision of the output tends to be less than desired. Also, because the abrasive material must be spun at extremely high speeds, the system requires highly accurate machinery. In addition, the machine must be able to accurately and consistently remove all the chips from the workpiece.
Two types of surface grinder are available for use in the workshop; namely, direct-drive and laser units. Each type of machine has its own advantages and disadvantages and is suited for particular applications. For example, a laser surface grinder is suited to small, intricate, complex or precision machined operations such as jewelry making, airplane making, precision bearings and other precision components. It delivers very high precision results and is also an ideal choice for applications requiring high-volume production.
On the other hand, a direct drive surface grinder operates by combining the power of the rotating disc and the grinding wheel into one single mechanism. This makes the system very economical and suitable for simple, low-volume operations. The discs are typically made from ceramic or aluminum oxide, and the grinding wheels may be made from steel, titanium or magnesium. These types of surface grinders are most suited to use abrasive materials on a small-scale basis.
In addition, there are two types of finish that a surface grinder can be fitted with, namely, wet or dry. A dry finishing process entails applying a thin layer of water resistance varnish or oil to the surface. This helps the finish remains intact for longer periods. On the other hand, a wet finishing process extracts the material from the chuck holds and seals the surfaces. This prevents the moisture from seeping into the chuck to hold and affecting the final outcome of the grinding process.
Overall, an abrasive cutting tool plays a vital role in various industries. Most importantly, it offers benefits such as greater accuracy, reduced operator fatigue, safety and minimal material consumption. These benefits translate into more profitability for operators and greater value for the customer. It is therefore important to consider investing in a quality surface grinder to ensure that it is able to deliver high quality results.
