Heavy Duty Column Surface Grinder

For heavy-duty abrasive cutting in the field of metal processing, column based heavy duty surface grinding is one of the most critical issues in the entire finishing process. After processes such as stamping, cutting and other complex machining, many rough work pieces will go to this surface processing step for further finishing under heavy duty premises based on the working of a precision spindle.

A heavy-duty surface grinding procedure that uses surface grinding spindle can produce a smooth finish on a flat or other specific surface. It is a widely used abrasive processing technology. By the spinning wheel are covered with rough particles, which cut off fragments of metal or non-metallic substances from the work piece, and smooth the surface of the work piece. There are many types of grinding machines, such as cylindrical, internal, center-less. 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. Although the heavy duty column surface grinder has not been widely purchased, it is still very practical for certain industrial fields.

CNC & Heavy Cutting

The CNC control of the entire part is a finishing step. This step uses a rotating grinding wheel to smooth the surface of metallic or non-metallic materials in order to render a refined physical situation by controlling the layers and impurities on the work piece surface, thus showing Fine physical state. A computer numerical control system is activated by a programming system. The hydraulic activation is also enacted by the CNC system.

The heavy-duty structure needs to be realized by the column structure, and the abrasive cutting process will obtain the required surface to achieve the functional purpose of engineer planning and programming. This situation also occurs in a milling machine such as a double column milling center, and in terms of mechanical properties, the mechanical structure of a surface grinder is composed of a grinding wheel, a work piece holding device, and a reciprocating table. During processing, the holding device would hold the material in place while it is being machined just like other column based milling machines.

Clamping & Work Pieces

Similar to the turning and milling processes, the clamping of the work piece is important for grinding, and the clamping mechanism can be completed by two methods in the grinding machine. The first option is to fix the ferromagnetic sheet in place by a magnetic chuck, and for non-ferromagnetic and non-metallic sheets, fix it in place by vacuum or mechanical means. The clamping mechanism is essential to the entire machining process, because only rigid positioning and clamping devices can be used to complete the work accurately and precisely under precise standards, and the entire process can be completed using advanced technology.

In the case of conventional grinding, work piece materials include aluminum, brass, steel, cast iron, and mild steel. Some of them are more stable and do not attach to the grinding wheel during processing, while others have different physical properties that can lead to corrosion and are not ideal 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 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 work piece. The operator must be aware of the shape change in order to modify the grinding wheel immediately, so that the desired steps can be performed through successful steps of grinding.

Precision and Surface Quality

The heavy-duty column surface grinder is a multi-function machine used to provide heavy-duty precision ground surfaces. Its use may be specific sizes or for surface finishing. The typical accuracy of the surface grinder depends on the type and use. However, on most surfaces grinder should be able to achieve a certain accuracy value. The grinding machine consists of a table that can travel both in the longitudinal direction and along the grinding wheel surface, the longitudinal feed is usually hydraulically driven, and the cross feed can also be hydraulically driven, but any combination of manual, electric or hydraulic pressure can depend on the final use of grinding machine should be clarified before purchase. Cross feed is simple, but with integration the whole schedule shall be taken care of. The accuracy value must be set accurately before processing, or the final output will be unstable and difficult to control. Using the column structure, CNC system, advanced spindle, and good grinding wheel, the grinding quality can be better and predictable.
