In many machine tool designs, the twin head (tooling head) is the main processing function, which attracts buyers due to its excellent processing flexibility and faster speed. The double attachment structure is a twin head structure rather than a single head as standard processing equipment. It is one of the commonly used and popular rigidity enhancement structures in the field of machine tools. The purpose is to improve its working performance and cutting rigidity and accuracy.
Grinding is considered as an abrasive cutting method, and twin head surface grinding is one of the most popular models. There are many varieties in the entire finishing process. After forming, milling, and other complex machining, many workpieces will go to this step to further complete the procedure in the production line. The process of surface grinding using single column and double column surface grinders can produce smooth finished surfaces on flat or other specific surfaces. However, there are many types of grinders, such as cylindrical grinding, internal grinding, and centerless grinding. Since the beginning of history, surface grinding has been the most common type in industry, and now it has been the same in various grinding operations. With these functions, it is only a twin head double column surface grinder, and to become a super grinder, the control system should also be included.
In addition to hardware considerations, program-based grinding is a finishing process that uses a rotating grinding wheel to smooth the surface of metallic or non-metallic materials to provide a fine physical state by removing layers and impurities under the surface of the workpiece. The management of computer numerical control mechanism driven by numerical control digital system. The single head working device is based on two columns of supports. This basic structure is installed with the tool system. The grinding process will obtain the required surface to achieve the functional purpose. This is the function planned and programmed by the engineer, just like the twin head and single head units.
The mechanical composition of the twin heads is also very interesting. The mechanical structure of the surface grinder is composed of an abrasive wheel, a work piece holding device, and a reciprocating table, so during the processing process, the fixtures are fixing the materials in place and are being processed. The clamping mechanism can be completed in two ways: the first is for ferromagnetic pieces. This type is fixed in place by an magnetic chuck, but for non-ferromagnetic and non-metallic workpieces, it can be fixed in place by vacuum or mechanical ways.
Either way, the clamping mechanism is essential for the grinding process. Only through the stern positioning and clamping, the work can be completed accurately at a precise level. In addition to the computer management of the cutting path and the double column structure, there are other important parameters that affect the grinding accuracy. There are many key factors that affect surface grinding, but the most important factors are the material of the grinding wheel and the workpiece. Traditionally, workpiece materials include specific styles of metal materials, such as aluminum, brass, steel, cast iron, mild steel, and other workpieces.
The twin head is where the grinding wheel is installed, and the material is the top priority of the grinding process. Among many material choices, some of them are more stable and will not adhere to the grinding wheel during processing, while others have different physical properties that will cause corrosion and are not suitable for further applications. As far as the shape of the grinding wheel is concerned, the shape is not limited to a specific shape, but may be various shapes and profiles.
In fact, under normal circumstances, on-site operators can repair wheels for special usages and purposes. It is worth noting that in the surface grinding process, the shape of the grinding wheel will affect the reverse shape of the workpiece. The operator must be aware of the shape change in order to immediately modify the grinding wheel, so that the required grinding can be smoothly carried out to achieve the desired quality and productivity. Between the entire metal working procedure, the surface grinder is a machine used to provide a precision grinding surface, and its purpose may have a specific size or used for surface finishing, so the typical accuracy of the surface grinder depends on the type and usage. However, a certain accuracy value should be achievable on most surface grinders.
How to grind smartly is the issue of the 21st century industry. Due to the grinding machine is composed of a table that can move longitudinally and penetrate the surface of the grinding wheel, the longitudinal feed is usually powered by a hydraulic device, cross feed. However, it can also use any combination of manual, electric or hydraulic, depending on the end use of the grinder. This is why the functionality must be discussed in detail before purchase, and the accuracy value needs to be set well before processing, or the final output result will be disappointed to industrial consumers in the industrial world.
