Precision machinery parts processing technology key points in shenzhen machinery processing industry has a large and small enterprises is very much, most of the mechanical processing factory will have the complete mechanical equipment and personnel.
process, needs a process engineer to process writing, process route is very important to write, precision machining process is done depends on the process route, it is very important to the quality of the products and production efficiency has the status, so the mechanical processing factory attaches great importance to the process of writing.
So we in the precision machining for its processing route to write note what points?
In precision machining, the surface of the workpiece is product display intuitive feelings to the customer, make sure the surface processing methods: understand the characteristics of the various processing methods and master its machining accuracy and surface roughness, on the basis of economic choice to ensure machining quality, productivity and economy method;
In machining process, the choice of positioning base: according to the principle of rough and finish machining benchmark choose reasonable positioning base of each process;
Reasonable selection of machining process and can not only reduce product supplies, scrap and lower cost, also can promote the workpiece machining efficiency.
On the basis of the analysis of precision machining, coarse divided parts, half fine, finishing stage, the concentration and dispersion degree, and determined the process on the surface of the reasonable arrangement of the processing order, thus write parts machining process route;
In machining complex parts, can set up several schemes, a meeting to discuss after analysis and comparison, pick out the economy and better benefit for the customer processing scheme.
Determine the machining allowance of each process and procedure dimension and its tolerance;
Choose workpiece processing equipment and tooling, clamp, quantity and cutters, etc.
Mechanical processing equipment should be selected to ensure that the processing quality, but also to the economic and reasonable.
Under the condition of batch production, general universal machine tools and special tooling should be adopted;
To determine the main process of technical requirements and testing methods;
Determine the cutting parameter of each process and time quota;
Fill in the process card, distributed and artifacts to workshop production.
Above for precision machinery processing craft route to write related matters, machining process is on the basis of process, change the shape, size and the relative position of production object and nature, etc. , making it a finished product or semi-finished products, is each step, a detailed description of each process.
So specific process analysis to write also requires a combination of customer summing up experience and analysis of workpiece is http://www.
