Automatic production lines are the manufacturing sites that are driven by automated production line integration technology that need least human worker participations. Such models are also called automation line in short. The automated production lines are an old idea that already exists in the late twentieth century, yet the technology then did not allow such dream to come true.
Today, automated production lines are very common, especially in the smart manufacturing sites but there are still some different levels of automation. That is, even though many factory owners claim their manufacturing sites are automated production lines, the definition of how automatic they are, is by far a very diversified subject for discussion in the industry.
CNC machine tools are commonly used in the automated production lines since the CNC technology can be easily integrated into the whole automatic process. For instance, CNC grinding is a finishing process which utilizes a rotational abrasive wheel to smooth the surface of metallic or non-metallic materials in order to deliver a refined physical situation, and this can be connected with the procedures beforehand. During the process, the CNC grinders remove the layer and impurities on the work piece surfaces under the control of automated computer numerical control mechanism that is driven by programmed procedures.
So, these processes will attain a desired surface automatically for functional purposes that are planned and programmed by experts. In regard to the mechanical composition, the mechanical structures of surface grinders are composed of an abrasive wheel, a work piece holding device, and a reciprocating table. These are all the parameters needed to be calculated for the automated production lines. During machining, the holding device holds the material in place while it is being machined. The clamping mechanism can be done via two methods: one is for the ferromagnetic pieces, which are held in place by a magnetic chuck, while for the non-ferromagnetic and nonmetallic pieces, they are held in place by either vacuum or mechanical means. The clamping mechanism is crucial to the whole processing of auto surface grinder, since only with the rigid positioning and clamp, can the work be achieved in ideal working environment.
In the case of automated grinding, there are critical factors that may affect surface grinding quality. Those who want to build automated production lines need to take care of those issues before they construct the production sites. For instance, there are the materials of the grinding wheels and the material of the work pieces that matter. Typically, work piece 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 further application. In the other hand, speaking of the shape of the grinding wheel, the shape is not confined to specific shapes but could be a variety of shapes regarding to the shapes. Manufacturers have to pay attention to these details of their production lines since these details would determine their eventual machining condition and the final outcome.
In reality, onsite operators rather than those engineers can dress the wheels for specific usages and purposes to achieve the smooth operation. There is one thing that is noteworthy that, during automated surface grinding on the automated production lines, the wheel shape will be affected to the reverse shape of the work piece, so that operators have to be aware of the change of the shapes in order to instant modifications onto the grinding wheels so that the desired grinding could be continued.
Since surface grinders are machine tools utilized to provide precision ground surfaces, and the purpose could be of specific size or for the surface finishing. The typical accuracy of a surface grinding machine depends on the types and usages; however, a certain level accuracy shall be achieved on most surface grinding cases. Among all the grinding processes, surface grinding is the one of the most general one of the various grinding operations. CNC grinding is a finishing process which adopts a rotational abrasive wheel to smooth the surface of metallic or non-metallic materials in order to deliver a refined physical situation by removing the layer and impurities on the work piece surfaces under the control of computer numerical control mechanism that is driven by the computers.
