CNC-based machine tools are standard machines for large-scale production models in modern industry. In the process of metal grinding, CNC cylindrical grinder is one of the most commonly used grinders. It is used to shape the outer surface or inner surface of the work piece. The cylindrical work piece is cut and ground by an abrasive. In the industrial field, grinding machines are used to shape the outside, inside, or surface side of a work piece by a continuous grinding mechanism using various cutting methods. Although this is a relatively rough description, there are several types of grinders, such as centerless grinders, surface grinders, cylindrical grinders, roller grinders, etc. These CNC grinders have different uses based on different applications, and each function has unique working features. CNC cylindrical grinding machines can process various shapes, but the object must have at least one central rotation axis so that it can rotate concentrically. The definition includes not limited to cylindrical and other shapes, but can certainly be constituted by shapes such as cams, ellipses, crankshafts, and other metal work pieces.
There are inner and outer diameters inside and outside the cylindrical workpiece. Despite the large inventory of grinders in the industry, in terms of grinder inventory, belt grinders, bench grinders, cylindrical grinders, surface grinders, tool and cutter grinders, fixture grinders, gear grinders, mold grinders, angle grinders and roller grinders, and some custom types have limited models. Among many grinders, CNC cylindrical grinding machines are very popular models.
Due to the design of many cylindrical workpieces, the multiple grinding purposes that can simultaneously meet the inner diameter, outer diameter and other detailed contours are completed by today's mechanical engineers according to the technology we know today. There may be many reasons why cylindrical workpieces are so popular. However, if you conduct a more in-depth study of this topic from a theoretical perspective, it should be noted that in most cases, CNC cylindrical grinding is almost the same as CNC roller grinding. There are still some key unique features in the machining details between these two types of CNC grinders.
Speaking of CNC roller grinding method, this is specially designed to solve some special problems. These problems often require machines developed for certain heavy operations. CNC grinders usually consist of a table, 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, but depending on the ultimate purpose of the machine selected, any combination of manual, electric, or hydraulic methods can be used. That is to say, the essential definition of cylindrical grinding makes it different from roller grinding, which is that the machine tool must have four key roles.
In the article, we will introduce them one by one. The first step is to put something. At the beginning, the first step is that the workpiece must rotate continuously throughout the process. The second step is that the grinding wheel must rotate continuously. The third step is to push the grinding wheel forward and backward toward the workpiece. Finally, move the workpiece relative to the grinding wheel. Today, most cylindrical grinders 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 actually a cutting method that helps to further polish, finish, and modify the target workpiece in a stable state.
CNC stands for Computer Numerical Control System, which is a computer-based machine running calculations. The system is not limited to metal processing, but also includes the plastics and rubber industries. Observing that with the CNC system, the working mode is more likely to be stable and easy to arrange, while also avoiding many occupational safety problems caused by manual operations in the past. One of the most famous CNC-based machine tools is the CNC milling machine, which is the first prototype of all machine tools that have historically adopted CNC technology.
CNC milling machine is a process that uses rotating tools under the control of a computer numerical control (CNC) system to advance the tools into one or more workpieces to remove material. This processing method can be done in different directions. In addition to turning, milling also covers a wide variety of operations and has a wide range, from a single tiny part to heavy and large-scale linked milling operations. This is similar to turning, where milling is one of the most commonly used machining methods and provides precise tolerances. As a result, the research and development of milling methods are widely welcomed in the industry due to the productivity and effective characteristics of their production and processing of workpieces with complex contours, while traditional lathes are relatively difficult to achieve. With the development of the milling process, many machining methods have emerged, and one of the most popular and widely used methods is the machine center machine. After this application, people added CNC to the grinding machine, so the cylindrical grinder with CNC was also promoted in the market.
If people look forward to the development of grinding machines, it is easy to find a trend. In the era of the modern metal processing industry, grinding is a process that must be performed after general processing processes including cutting, milling, boring, cutting, drilling, etc. Obviously, only through a comprehensive grinding process can the cylindrical workpiece be prepared for the next machining stage of the next step. Therefore, in production lines and factories, almost all manufacturers now prepare their own internal grinders on their own production lines, whether they are CNC cylindrical grinder or surface grinder.
