In the metal grinding field, the cylindrical grinding machines are one of the most common grinding models. It is used to shape the side or shape of the inserted workpiece by the grinding mechanism. In the field of metal processing, a grinding machine is used by using this is a relatively rough description, but there are many types of grinders, such as centerless grinder, surface grinder, cylindrical grinder, roller grinder, etc.
These grinders have different uses based on multiple uses, have certain functions and their unique working characteristics, and cylindrical grinding machines can process various shapes. The definition includes is not limited to coaxial shapes, cylindrical, elliptical, crankshaft and other shapes.
Although there is a large inventory of grinding machines in the industry, the models are limited in terms of grinding machine inventory. Examples include belt grinder, bench grinder, universal cylindrical grinder, surface grinder, tool and cutter grinder, fixture grinder, gear grinder, die grinder, angle grinder and roller grinder, as well as certain custom types of models. Among many grinders, cylindrical grinding machines are very popular models. Since there are many cylindrical workpieces designed by mechanical engineers today, they can meet a wide range of grinding purposes. Including inner diameter, outer diameter and other detailed contours. There may be many reasons why cylindrical workpieces are so popular, but if you conduct more in-depth research on this subject, you should note that in most machining details. Cylindrical grinding is almost the same as roller grinding, but there are still some key distinctive features between these two machines.
On the one hand, the roller grinding method is specifically designed for certain problems, which usually require machines developed for certain heavy operating tasks. The grinding machine consists of a worktable, which can cut the surface of the grinding wheel both longitudinally and transversely. Longitudinal feed is usually hydraulically driven, and cross feed is usually hydraulically driven. However, depending on the ultimate purpose of the machine, any mixing method, manual, electric or hydraulic, can be used. Specifically, the basic definition of cylindrical grinding machines is different from roller grinding machines, and they must have four key factors. Next, we will introduce them one by one.
First, the work piece must rotate continuously throughout the process. Secondly, the grinding wheel must continuously rotate. Third, the grinding wheel feeds the work piece forward and backward. Finally, move the work piece relative to the grinding wheel. Today, most cylindrical grinding machines use these four movements, and there are still grinding machines that use only three of these four movements for machining, but the overall grinding process is basically similar to the mechanism described. It is important to realize that grinding is a cutting method that contributes to stable polishing, finishing, and modification of the target work piece.
Contrary to cylindrical grinding, if the workpiece is not circular or cylindrical, but is essentially flat, it is surface grinding, which is another method. The machine that can precisely machine workpiece surfaces is the surface grinding machine. Different to universal cylindrical grinder, its purpose is to create specific sizes or surface treatment. Since the earliest stages of human civilization since ancient times, the surface grinding mechanism is the most conventional grinding operation because it is a finishing process that uses a rotating grinding wheel to smooth the theoretically flat surface of metallic or non-metallic materials. By removing the oxide layer and impure parts on the surface of the workpiece, its appearance is more refined. The typical accuracy of a surface grinder depends on the type and application, but at least for most surface grinders, a certain accuracy value should be achieved. The tool assembly of the grinder is another key point, it can make both cylindrical grinding and surface grinding accurate. The grinding wheel is not only limited to the cylindrical shape, but also has a variety of options, which can easily transfer the unique geometric shape to the object to be processed. Straight wheels can be trimmed by the operator to produce customized geometries. When grinding the surface of an object, it must be remembered that because the grinding process is the key to the grinding and cutting process, the shape of the grinding wheel will be changed to the material of the object.
Looking back at the history of the development of grinding machines, it is not difficult to find that in the era of the modern metalworking industry, grinding is a general process (including turning, milling, boredom or drilling). Obviously, only through the complete grinding process can the next step of the production line be continued. As a result, in manufacturing plants, almost all manufacturers now prepare their own grinding machines on their production lines, whether cylindrical or surface grinders, to keep up with today's rapid production pace.
