First: precision grinding machines use flexible clamping arrangements for grinding these thin workpieces, resulting in the final positioning and clamping of thin workpieces in this free country. The workpiece with a layer of rubber of 0.5mm between the magnetic operations is affected by the magnetic attraction of the workpiece. The rubber is very tight and the elastic deformation is small. Grind and then grind the flat workpiece. The repeated ground can meet the machining accuracy.
Second: use epoxy resin to bond the thin work piece to a plate in a free state. Sheet of plates and magnetic suction cups. One end of the plane paper plane, and then take off from the flat workpiece, grinding the surface plane on the other side of the workpiece. Because epoxy resin is the liquid before hardening, it can fill the flat open space between thin workpieces. When the epoxy resin hardens, the workpieces are bonded together as a whole, greatly improving the rigidity of the parts. According to the magnetic attraction, the clamping deformation of thin workpieces does not attack, and the grinding is straight and flat. The thick oil used in the surface grinder can also be used to replace the open space between the epoxy filled resin sheet workpiece and the magnetic chuck, to improve the rigidity of the parts, and you can get good results.
