When it comes to surface grinding machine tools, people think that it is the kind of grinding machine tools. Nowadays, the development trend of surface grinder in the world has changed. At present, the development trend of surface grinder is turning to forming, step, cutting in, rapid shaking and grinding of three-dimensional curved surface. It can be said that the flat grinding machine tool in Hangzhou has great potential for evolution.
There will be many problems in the continuous use of different surface grinder equipment, so with the solution of the problem, the product is also in the process of continuous upgrading. In China's large-scale parts processing, flat grinding is a type of machine tool with potential evolution. In order to ensure that the surface grinder in the normal work can better complete the work, so for the operator, the use of surface grinder need to pay attention to a lot of problems.
1. Clamping method of elastic gasket
The elastic clamping mechanism is adopted when grinding the sheet workpiece on the surface grinder to realize the positioning and clamping of the sheet workpiece in the free state. A layer of 0.5mm thick rubber is placed between the workpiece and the magnetic table. When the workpiece is attracted by the magnetic force, the rubber is compressed and the elastic deformation becomes smaller, so that the flat surface of the workpiece can be ground. Repeated grinding for several times can meet the requirements of machining accuracy.
2. Using temporary measures to strengthen the rigidity of sheet work pieces
Epoxy resin is used to bond the sheet to a flat plate in free state. The plate together with the sheet is placed on the magnetic chuck. After grinding the plane of one end of the sheet, take the sheet workpiece from the flat plate, place the flat side on the magnetic chuck, and then grind the other end plane of the sheet workpiece. Due to the fluidity of epoxy resin before hardening, it can fill the gap between the sheet workpiece and the flat plate. When the epoxy resin hardens, the workpiece and the plate are bonded together to form a whole, thus greatly enhancing the rigidity of the workpiece. Under the magnetic attraction, the workpiece will not produce clamping deformation, which creates conditions for grinding out flat surface. Thick grease can also be used to replace epoxy resin to fill the gap between the sheet workpiece and the magnetic suction cup, so as to enhance the rigidity of the workpiece, and good results can also be achieved.
3. Vacuum clamping mode
The pressure of atmosphere is used to clamp the workpiece for grinding. Its working principle is: the clamp is provided with a rubber sealing ring, and the sheet workpiece is placed on the rubber sealing ring, so as to form a sealing cavity between the workpiece and the clamp. The vacuum pump is used to draw the indoor air from the air extraction hole, and the workpiece is clamped. Because of the small clamping force, the circular grinding method can be used for grinding. When one end of the workpiece is ground and the other end of the workpiece is ground, the above method can be used and satisfactory results can also be obtained.
In many industrial production, there will be some security risks, so many times, we need to pay attention to safety when we work. In the use of surface grinder equipment, because of the extensive wear technology, so many times, the correct operation of the grinder is the only prerequisite to ensure safety.
