Design
Like other CNC machines, CNC grinding machines have become a key component in the design (design). The essence of the design is the design of the machine tool. It includes overall layout design, protection design, pipeline design, and the three are closely related.
Overall layout design The overall layout of modern CNC machine tools is an intuitive feeling for the viewer: beautiful, well-proportioned, smooth lines, bright colors, strong three-dimensionality, and strong integrity (machine, electricity, liquid, gas integration): give the user a User-friendly feeling: the machine tool is easy to operate, and the upper and lower workpieces are easy to adjust, maintain and troubleshoot.
Since a large number of mechanically operated handwheels on a conventional machine tool do not exist on a numerically controlled machine tool, the user only operates the machine tool by means of an electrical button on the (handheld) keyboard, so that the machine tool can be isolated from the operator and fully enclosed. This is one of the main features of today's CNC machine tools.
The overall layout design is a comprehensive design, an imaginative design. It is different from some principle design and structural design. Now a lot of software for the appearance design of machine tools is displayed in front of us. The designer can browse the appearance library of a large number of different types of machine tools, and through the color change of each part, the position adjustment of each appearance module, find a rendering effect suitable for the overall appearance of the machine tool. It is like a well-prepared machine tool placed in front of us to watch and evaluate, to find out the inadequacies and improve it, so that it can be successfully developed.
For the CNC special grinding machine, in addition to meeting the above requirements, the specificity of the grinding workpiece should be considered, so that the operator can consider the layout for the upper and lower workpieces and the safety of the operation. The key part that affects the layout design is the design of the machine platform (bed).
Protection design CNC machine tools high speed, high automation, high pressure drive, high pressure cooling, a large amount of oil, water, gas leakage, splash, bring some danger and pollution to the operator, the surrounding environment. Therefore, from the point of view of modern safety protection, CNC special-purpose grinding machines, like CNC machine tools, isolate the machining area, moving parts, and pipeline screens from the operator and design them into a closed type. This is also a requirement for the overall shape of the machine tool. Protective design is more than just a fully enclosed concept. For safe operation and safe operation, the machine also needs to design a large number of motion interlocks. Such as: open the door and power off, the grinding wheel is closed when the workpiece is replaced, and the waste liquid caused by the pollution is recovered and purified: a large number of warning signs are set in the most intuitive place of the operator.
Pipeline design CNC machine tools simplify the mechanical transmission structure, need to use electricity, liquid, gas for control and drive, plus cooling, cooling, etc., need to connect a large number of pipelines. How to deal with these different professional pipelines is a problem that our modern designers have to solve.
The pipeline design affects the appearance, assembly, protection, maintenance, anti-interference and checkability of the machine tool. At present, pipeline design mostly adopts the following methods:
The fully enclosed design of the machine tool is the best solution. It can be hung in the protective cover - screen, separated by pipeline or mixed pipeline, and the appearance is neat.
Mechatronic design. The electrical cabinet is fixed to the machine platform, and the operating box is integrated with the electrical cabinet or connected together by a standard cable drum. Make full use of the space around the platform or the surrounding design as a slot type wiring, which not only shortens the line connection, but also facilitates assembly inspection and maintenance.
The integration and independence of the hydraulic tank and hydraulic functions are fixed with the machine platform, which greatly reduces the pipe connection.
Cooling tank and various filtering functions, integration of condensation function, independent, to reduce piping.
Reduce the machine footprint as much as possible in the overall layout. Such as electrical cabinets and water tanks occupy up and down space.
6 Conclusion
The design idea of ​​CNC special grinding machine is to develop a feasible new grinding process through the user's current grinding process experience, and select a large number of existing mature module components and social functional components, focusing on the layout and shape of the design table.
