A surface grinder is a rotating tool used in abrasive metal machining. It is used to create a very smooth finish on rough surfaces. It is an extensively used abrasive processing method in which a rotating drum containing abrasive material is spun at high speeds against a stationary work piece, producing a rough, flattened face of it with a certain degree of roughness. This abrasive material is usually abrasive silicon carbide, diamond plate, or other such hard carbide particles.
It has numerous advantages over the more common wire wheel and belt grinders. It produces a totally smooth surface as a result of the abrasive material spinning at very high speeds. The grinding of a surface using a surface grinder is also referred to as grind-back or buffing. A drawback of using this method is that the work piece need not have a smooth surface to be worked upon; any rough surface can be taken into account.
Surface grinders are designed to remove fine burrs and other forms of defect from a workpiece by grinding away at them. A grinding wheel consists of a rotating metal rod having teeth arranged in a circular pattern around its axis. The rotation of the teeth creates a rough abrasive layer on the workpiece, which is removed by the grinding process. A magnetic chuck can be used along with a surface grinder for a more complete removal of the defect or burrs from the workpiece.
Magnetic grinding includes the use of a set of metal posts like those found in a lathe. These posts like the lathe’s wheels are placed in a magnetic assembly and the workpiece is placed between them. The workpiece then moves on a slide that is attached to the posts like a wheel. When the workpiece comes in contact with the magnetic grinding device, it is moved in the grinding circle thereby grinding away at the defects.
It is generally used in applications where the main machining process requires hard surfaces to be removed. The reason behind this is that soft or thin surfaces are usually easier to polish and finish than their harder counterparts. However, when the surfaces have to be ground, the work piece must be prepared for the grinding wheel to work properly. This includes making sure the work surface has been prepared to accept the grinding wheel. There are a few different types of surface grinder available for use in the machining process, depending on what the application is.
One type of surface grinder is the portable type and is useful for work in progress, or even on the work bench. The work surface can be set into the grooves of the grinding wheel and then the work can be moved around until the design is the best it can be. Another type of surface grinder is the stationary type and is designed for use in production areas. It can also be used in the same grooves as the grinding wheel to ensure that the best product can be produced. For high quality and consistent results, it is best to use the stationary type of grinder.
