Classification of Double Surface Grinders

Double surface grinders can be divided into horizontal double surface grinders and vertical double surface grinders according to the spatial state of the grinding wheel spindle. Among them, the horizontal double surface grinder has the characteristics of convenient grinding wheel angle adjustment and simple assembly process, but it occupies a large area and has poor feeding stability for thin and special-shaped workpieces. The vertical double surface grinder has a small footprint and good feeding stability. According to the box structure, it can be divided into a cantilever type double surface grinder and a frame type double surface grinder. Among them, the cantilever double surface grinder has the characteristics of simple structure, convenient processing and assembly, and low manufacturing cost. The frame type double surface grinder has the characteristics of good machine rigidity.

According to the feeding method of the workpiece, the double surface grinder can be generally divided into four types: disc type, through type, reciprocating type and swing type. Among them, the disc type and the through type are more commonly used. Disc type: The feeding disc runs continuously, the workpiece is placed in the hole opened on the feeding disc, driven by the feeding disc, and the grinding is completed through the grinding zone between the two grinding wheels. This method has a high degree of automation and is suitable for flat parts of any shape. Through type: the workpiece is placed in the guide zone formed by two steel belts, and the workpiece pushes the previous workpiece through the grinding zone in turn. This method is more efficient and can realize continuous production, but it is only suitable for workpieces with relatively regular shapes.

The reciprocating and swinging types are respectively the through-type and swing-type variants. During grinding, the workpiece will reciprocate linearly or oscillate in the grinding zone while the grinding wheel is gradually fed. This type of double surface grinder is mainly used for the processing of small batches and large grinding allowances or high-precision workpieces.

This article introduces the double surface grinder. Through this article, we understand that the surface grinder is high-precision surface processing equipment with a high-strength mechanical structure and stable accuracy. At the same time, we also know that the classification of double-end face grinders is divided into horizontal double-end face grinders and vertical double-end face grinders according to the form of spindle equipment. According to the workpiece feeding method, it can be divided into four types: disc type, through type, reciprocating type and swing type.
