Regarding cylindrical grinding, there are mainly two types of machine tool cutter arrangements: horizontal or vertical. Like turning and milling, the grinding direction can be adjusted base on industrial use to suit different market requests. Vertical arrangement is the most common grinding method, which can solve most grinding processes of CNC plain cylindrical grinders with the grinding head placed vertically. For cylindrical grinding machines, the working physics is basically similar, and cylindrical grinding must meet the following four steps.
In order to complete ordinary cylindrical grinding, the four steps are: the workpiece must rotate constantly as designed, the grinding wheel must rotate constantly, the grinding wheel feeds forward and backward toward the workpiece, and finally, the workpiece moves relative to the grinding wheel.
Plain grinders and cylindrical grinders are popular grinders that can be used under manual or CNC control. The former is used to grind plain surfaces, and the other is used to grind the inside or outside of cylindrical work pieces.
In fact, the majority of plain cylindrical grinding machines today use all the four movements as the basis of the grinding works, but there are still manual or CNC plain cylindrical grinders that only use three of these four actions to process the grinding mechanism, and the effect can reach the good and ideal results. Since other types of grinders can achieve the expected quality, there is no absolute principle in mechanical processing, only the way to make things go smoothly.
The manual or CNC plain cylindrical grinders are one of the grinding machines, which are used to shape the external or internal sides of the cylindrical workpiece by the grinding mechanism. CNC plain cylindrical grinders can process various shapes. However, the workpices must have at least a central axis of rotation so that it can rotate concentrically as this is a very fundamental basis. This includes but is not limited to such shapes as cylindrical, but from such as cam, ellipse, crankshaft, etc.
Plain grinders and cylindrical grinders are one of popular grinding machines and can under manual or CNC control, the former is use to grind plain surface and the other is designed for grinding internal or external sides of cylindrical work pieces.
The surface grinding is the earliest version of the grinding industry. After the invention of surface grinding was first published, the industry began to introduce cylindrical and other roll grinding. For industrial processing, surface grinding is one of the most important links in the entire process. After forming, cutting and other complex processing, many workpieces will enter this step for further finishing meeting industrial demands.
Moreover, the surface grinding process is used to produce smooth finished surfaces on flat or other specific surfaces. It is a widely used abrasive machining process by which the spinning wheel are covered with rough particles (grinding wheels), which cut chips of metallic or non-metallic substances from the workpiece to form a flat or smooth surface. In all grinding processes, surface grinding is the most common of various grinding operations. CNC grinding is a finishing process, which uses a rotating grinding wheel to smooth the surface of metallic or non-metallic materials in order to provide a fine physical state by removing layers and impurities on the surface of the workpiece under the control of the computer numerical control mechanism that is driven by programmed processes. As a result, these grinding procedures will obtain the required surfaces for functional purposes planned and programmed by engineers. Regarding the mechanical composition, the mechanical structure of the surface grinder is composed of a grinding wheel, a workpiece fixing device and a reciprocating table. The design of the reciprocating table makes the work easier.
During the grinding process, the holding device will hold the material in place when processing the material. The clamping mechanism can be completed in two ways: one is for ferromagnetic parts. They are fixed in place by magnetic chucks, while non-ferromagnetic and non-metallic parts are fixed in place by vacuum or mechanical means. The clamping mechanism is essential to the entire processing because only with a strong positioning and clamping device can the work be completed accurately and precisely. The key factors affecting surface grinding are the material of the grinding wheel and the material of the workpiece. Generally, workpiece materials include aluminum, brass, steel, cast iron, and mild steel. Some of them are more stable and will not attach to the wheel during processing, while some are with different physical natures that would lead to corrosion that is not ideal for other industrial usages for users all over the world across applications.
Choosing the right machine tool for your company is very important and affects the follow-up quality of all its work. In addition to lathes, milling centers, and boring machines, the last part is also very important. If the on-site operator knows and wants to manage it, a good plain cylindrical grinding machine can help you deal with various grinding tasks without further assistance.
