Surface grinders are used for various grinding processes including truing flat metal stock, squaring material within tenths (.0002 inch), sharpening cutting tools and for sharpening punch and die sets. A surface grinder normally consists of a magnetic chuck, which resembles a table, the grinding wheel that is attached to a rotating spindle, and a few handwheels (if manually operated). The workpiece is placed on the magnetic chuck and the chuck is then activated either by a switch or lever. When the chuck is activated the part is then held firmly to the magnetic chuck. The grinding wheel is then moved down to the top of the workpiece using a handwheel, until the grinding wheel touches the part (carefully), then you can begin moving the table side to side and front to back until the entire surface of the part is ground. If more of the surface needs to be ground, move the table so the grinding wheel is off the workpiece and lower the grinding wheel about 0.0002" to 0.0004" using the tick marks on the handwheel and begin moving the table again, this process can be repeated until the desired dimension is accomplished. Our automatic machines move back and forth under hydraulic power via settings on the control panel. A digital readout is a recommended option for precision surface grinders. If you need high accuracy, consider one of our machines that are manufactured in Taiwan, not China. Remember to follow all safety rules for surface grinders as these machines can be dangerous if used improperly. Eye protection is a must.
