Fine Grinding Machines Variable Speed Drive System that ensures Selectable RPM to the wheels individually for all applications. The system is also equipped with Motorized forward Reverse System which maintains the plate flatness in process without any production loss, by controlling the RPM & direction of rotation of the carriers.
Jan 01, 2016· Machining of Sapphire is challenging due to its high hardness and brittleness. Fine grinding can be preferable over conventional grinding when machining ceramics because of the ability to provide a flat surface. However, the manufacturing cost for such materials is very high because of high tool wear and longtime machining.
High grinding performance and long tool life for processing of sapphire or SiC wafers ... realizes smaller grinding resistance by 30-40% than that of the electroplated wheel of the same size and improves the grinding performance. Realizes machining with higher surface precision than cutting, and is effective for plane machining of mating ...
Lapping / polishing is the effect of free-abrasive between the grinding disc and the flat workpiece, applying appropriate pressure to the workpiece, and the cutting effect of the non-directional grain surface produced by the workpiece, when the abrasive particles become fine and grinding If the disc (polished leather) is matched, the surface of the workpiece can achieve the mirror effect.
2, used for big quantity produce on the CNC machine, for miniature bearing, air compressor, crankshaft camshaft, high precision and the fine grinding end milling. 3, for the workpiece which has a complicated surface, and request grinding wheel has good edges, pinion gear knife, pull the sword, high precision gears, modeling, punch, etc.
Dec 23, 2018· The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
Mar 20, 2019· Grinding is an important abrasive machining process in many manufacturing chains. In order to improve the material removal in the grinding of sapphire .
For sapphire machining damage can be especially detrimental because it can create significant stresses in the surface and sub-surface regions. ... including grinding and drilling, are still in the ...
Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).
