Grinding wheel dressing

Grinding wheel dressing, shaping and sharpening is usually divided into two processes. For trace shaping the grinding Diamond blade, to achieve the required geometry and precision, and to a fine abrasive tip broken, the formation of micro blade; dressing is removed by a combination of abrasive agent, the abrasive grains have a chip space between , binding agent and to highlight the abrasive, the formation of the cutting edges. For multi-pore vitrified grinding wheel (including diamond and CBN grinding wheels), as binders for the loose type, usually shaping and sharpening can be completed; while for binding agent is dense wheel (such as resin, metal binding agent) , then shaping and sharpening required separately. Grinding wheel of the most effective tool for shaping polycrystalline diamond tools devaluation. With a single particle diamond dresser, dressing tool wear due, often affect-surface precision. As with diamond wheel dresser, cutting tools tool to avoid excessive wear and tear, and to get a better wheel topography. Trimming device feeding accuracy is higher, the amount of each feed should be controlled at the micron level. Excessive trim only affects the grinding quality, will greatly reduce wheel life. Dressing in many ways, generally using mechanical methods (such as corundum block cut dressing, hydraulic jet sharpening method) or electrical processing method. Latter binding agent for metal grinding, the grinding wheel as an anode electrolysis by spark or erosion of the metal binding agent; if the binding agent is added to the graphite powder, this method is also applicable to the resin, vitrified grinding wheels.
