The Basics of Surface Grinding
Surface grinding is the one of the more widespread grinding operations; it involves a finishing process that makes use of a rotating, abrasive wheel to smooth a flat surface. These surface's are comprised of either metallic or non-metallic materials and result in a refined look and attain a desired surface which serves a functional purpose.
Surface grinders are composed of an abrasive wheel, a workholding device commonly called a chuck, and a reciprocating or rotary table. The chuck holds material in place as it is being worked on. It can do this one of two ways: ferromagnetic parts are held in place by a magnetic chuck, while non-ferromagnetic and non-metallic items are held in place by vacuum or by mechanical means. A machine vice placed on the magnetic chuck can be used in order to hold magnetic workpieces only if a magnetic chuck is available.
The trade phrases 'down grinding' and 'up-cut grinding' illustrate further parameters of grinding techniques. With down grinding, the direction of rotation of the grinding wheel at the point where it contacts the work piece is identical to the feed direction of the machine table. If the wheel is counter-rotating to the feed movement, the process is referred to as up-cut grinding. In a comparison of the two techniques, the latter delivers fifteen percent higher forces and aids is promoting the formation of heat nests at the point of contact between the wheel and the work piece.
Typical work piece equipment includes cast iron and mild steel. These two materials do not seem to clog the grinding wheel while being processed. Other materials include aluminium, brass, stainless steel, and some plastics. When grinding induces at high temperatures, the materials tend to become weakened and are more inclined to corrode. This can result in a loss of magnetism in equipment where this is applicable.
Grinding wheels are not limited to a cylindrical shape, and can have numerous options that are helpful in transferring diverse geometries to the object being worked on. Straight wheels can be dressed by the operator to produce custom geometries. When surface grinding an object, one has to remember that the shape of the wheel will be transferred to the material of the object like a mirror image.
Utility grinding machines are used for offhand grinding. In this practice, the work piece is held in the hand and held against the rotating grinding wheel. The accuracy of this type of grinding machine will depend on the operator's dexterity, skill, and knowledge of the machine's capabilities and the nature of the work. These machines consist of horizontally mounted motors with grinding abrasive wheels attached to each pole of the motor's shaft.
Vopas Precision Grinding applications include: Gauge Plates, Parallel Blocks, Oil Pump Bodies and Flanges.
