Double column surface grinder manufacturers tell you that a surface grinder is a type of grinder. Mainly use the grinding wheel to rotate and grind the workpiece so that it can achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of the rectangular worktable surface grinder are the width and length of the worktable, the The main parameter of the shape table is the diameter of the table. According to the different types of shafts, it can be divided into horizontal shaft and vertical shaft grinders.

 So how many grinding methods do we have when we use them? The following will explain to you:
1. Use temporary measures to strengthen the rigidity of thin workpieces
The sheet workpiece is bonded to a flat plate in the free state using an epoxy bond. The plate is placed on the magnetic chuck together with the sheet. After grinding the plane of one end of the sheet, take the sheet workpiece off the plate, put the polished side on the magnetic chuck, and then grind the other end of the sheet workpiece. Because the epoxy is fluid before it hardens, it can fill the gap between the thin workpiece and the flat plate. Double column surface grinder manufacturers tell you that when the epoxy resin hardens, the workpiece and the plate are bonded together and become a whole, which greatly enhances the rigidity of the workpiece. Under the magnetic attraction, the thin workpiece will not be clamped and deformed, creating conditions for grinding a flat plane. Thick grease can also be used instead of epoxy resin to fill the gap between the thin workpiece and the magnetic chuck to enhance the rigidity of the workpiece, which can also achieve good results.
2. Mechanical clamping method
 Use the flat-nose pliers in the accessories of the surface grinder to use the magnetic table to hold the small flat-nose pliers on the thin workpiece. Because the flat-nose pliers have a certain height, the jaws are subject to less magnetic force. Use the method of gradually decreasing the feed to grind one plane of the thin workpiece and then remove it. At this time, put the ground plane on the magnetic table, and then grind the other plane of the thin workpiece, and repeat the grinding several times. , the flatness of the two planes meets the requirements.
3. Vacuum clamping method
Grinding is performed by clamping thin workpieces with atmospheric pressure. The working principle is as follows: the clamping body is provided with a rubber sealing ring, and the thin workpiece is placed on the rubber sealing ring, so that a sealing cavity is formed between the workpiece and the clamping body. Use a vacuum pump to extract the indoor air from the exhaust hole, and then the workpiece is clamped. Due to the small clamping force, the grinding process can be carried out by the circumferential grinding method. The manufacturer of Double column surface grinder tells you that after grinding one end of the thin workpiece, you can use the above method to grind the other end of the thin workpiece, and you can also get satisfactory results.
4. Pad elastic gasket clamping method
The manufacturer of Double column surface grinder tells you that when grinding the above-mentioned thin workpieces on the surface grinder, an elastic clamping mechanism is used to enable the thin workpieces to be positioned and clamped in a free state. A layer of rubber with a thickness of 0.5mm is placed between the workpiece and the magnetic table. When the workpiece is subjected to magnetic attraction, the rubber is compressed and the elastic deformation becomes smaller, so that the flat surface of the workpiece can be ground. Repeated grinding several times can meet the requirements of machining accuracy.
The above is the relevant knowledge points that the Double column surface grinder manufacturer told you. I hope the above content can be helpful to everyone. Thank you for your viewing and support. We will organize more information for you later. Please pay attention to our website updates.
