Single Head Double Column Surface Grinder

Taking the accessory single head as standard processing machines, the column and double column structures are two common and popular rigidity reinforcement structures used in the CNC machine tool field to improve machines’ working performance and cutting rigidity. Regarding abrasive cutting, single-head surface grinding is one of the most popular CNC models, and there are many varieties in the entire CNC finishing process. After forming, milling, and other complex machining processes conducted by machines, many work pieces will be processed to this step for further finishing procedures in the production lines.

The procedure of CNC surface grinding machines using single and double column type CNC surface grinders can produce a smooth finishing surface on a flat or other specific surface. There are many types of grinding machines, such as cylindrical, internal and center-less grinding machines. Since very early history, surface grinding has been one of the most common grinding methods in the industry, and until now it is still one of various grinding operations. Program based grinding is a finishing process that uses a  rotational abrasive wheel to smooth the surface of metallic or non-metallic materials to provide fine physics by removing layers and impurities on the surface of the work piece under the control of a computer numerical control system, which is driven by a CNC digital system.

Single Head & Double Column

The single head work is based on two columns of support. This basic structure and system is installed with the tool system. The grinding process will obtain the required surface to achieve the functional purpose of engineer planning and programming. Regarding the mechanical composition, the mechanical structure of the surface grinder is composed of grinding wheel, work piece holding device, supportive systems, and reciprocating worktable. During processing, the fixture will fix the material in place when processing the material. The clamping system can be completed in two ways: the first is for ferromagnetic pieces. This type is fixed in place by an electromagnetic chuck, but for non-ferromagnetic and non-metal parts, it can be fixed in place by vacuum or mechanical methods.

Moreover, the clamping mechanism is essential for the entire machining process. By 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 material of the workpiece. Traditionally, workpiece materials include specific styles of metal materials, such as aluminum, brass, steel, cast iron, mild steel, and other materials.

Grinding Wheels

The material is a big problem in the grinding process. In many material choices, some materials are more stable and will not attach to the grinding wheel during processing, and some materials have different physical properties. These materials will lead to corrosion, so it is not suitable for further application. As far as the shape of the grinding wheel is concerned, the shape is not limited to a specific shape, but may be of various shapes. On-site operators can trim 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 desired grinding could be carried on with smooth pace that could lead to the intended quality as well as productivity.

Furthermore, in the entire metal working procedure, the surface grinder is a machine tool used to provide a precision ground 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 typeand usages. However, a certain accuracy value should be achievable on most surface grinders. Since the grinder is composed of a worktable that can travel both in the longitudinal direction and along the end face of the grinding wheel, the longitudinal feed is usually driven by hydraulics, such as cross feed, but any combination of manual, electric, or hydraulic depends on the ultimate usage of the grinder. This is why it is necessary to discuss functionality in detail before buying, and the accuracy value must be set accurately before processing, so the final result will be disappointed to industrial consumers in the metal grinding sector.
