Solution of Grinding Sheet Workpiece by Double Face Surface Grinding Machine
In recent years, with the rapid development of mechanical engineering, the processing requirements of low bending stiffness workpieces are particularly high, and the accuracy requirements are getting higher and higher. Generally speaking, due to the different structure, appearance and material properties, the workpiece with poor bending stiffness is a low bending stiffness workpiece, and the sheet workpiece is a typical low bending stiffness workpiece. This article will explain the double face surface grinding machine grinding chip related knowledge.
double face surface grinding machineIt is a kind of grinding machine. The grinding wheel is mainly used to rotate the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into two kinds: rectangular worktable and circular worktable. The main parameters of the rectangular worktable surface grinder are the width and length of the worktable, and the main parameters of the circular worktable are the diameter of the worktable. According to the different shaft can be divided into horizontal and vertical shaft grinding machine. Such as M7432 vertical axis circular table surface grinder, 4080 horizontal axis rectangular table surface grinder.
The double-face surface grinder is one of the important equipment in any precision machinery manufacturing and production workshop. Although its function is not as good as that of a CNC lathe, it is an essential mechanical equipment for fine processing. Mainly used for metal materials, resulting in clean and accurate smoothness. The surface of the workpiece is ground with a circular grinding wheel. The workpiece can be clamped with a fixture, or it can be tightly attached to the electromagnetic induction worktable, and the operating table can also move under the grinding wheel.
Double-face surface grinder: Common sheet workpieces include thin workpieces, such as sealing rings, rolling bearing support rings and friction plates. The rigidity of these workpieces is relatively weak, and they are easily affected by various forces and thermal effects during grinding, which promotes the large deformation of the workpiece under the adsorption of the magnetic field. After grinding, the workpiece is restored to its original state. Although the required thickness is achieved, the flatness does not meet the requirements. The following is a brief introductiondouble face surface grinding machineSolution for grinding sheet workpieces.
double face surface grinding machineSolution for grinding sheet workpieces.
1. Gasket contour block: The grinding piece workpiece can also be a gasket contour block under the workpiece. The four sides of the workpiece adopt blocks, sharpening knives, multi-laser knives, the front of the grinding parts, and detachable contour blocks, and then directly adsorb them on the worktable, which can improve the actual grinding effect and achieve the plane regulations.
2. Gasket Elastic gasket: On the plan view of both ends of the ground sheet workpiece, a thin rubber sheet or a cotton pad with accumulated pores can also be placed between the workpiece and the electromagnetic induction console. When the workpiece is magnetically adsorbed, the rubber plate will shrink and the elastic deformation of the workpiece will decrease, so the workpiece will be relatively vertical. After grinding the workpiece several times continuously, the workpiece can be immediately adsorbed on the workbench to meet the requirements of dimensional accuracy.
3. The flat-mouthed pliers in the grinder accessories: rely on the electromagnetic induction console to suck up the flat-mouthed pliers tightly. Since the flat-mouthed pliers have a certain height, the magnetic adsorption effect of the shaft will be very small. Choose the method of gradually reducing the amount of the knife to polish the front side of the sheet-like workpiece. After grinding, take out the workpiece, immediately put the workpiece into the electromagnetic induction worktable, and then continuously grind the back of the sheet workpiece to make the flatness of the workpiece meet the requirements.
