Today, many more various processing on the market, but not all are suitable for processing, using a different machine, in particular, to carry on the processing, so we should according to own actual situation, to choose, then the principle of precision machining and processing technology of what?
Pure is the focus of the basic level to consider how to reduce the error, improve accuracy, so choose essence on the surface of the basic principle is:
The first: benchmark superposition principle. Should choose as far as possible the design of the benchmark as locating datum. Especially in the final finish, guarantee the accuracy, more attention should be paid to this principle. So that we can avoid position error caused by the benchmark deviation;
Second: the benchmark unified principle. Should choose unified locating datum of all kinds of surface treatment, ensure accuracy of position between the various surfaces of the as far as possible; Sometimes also follow the principle of common benchmark, repeated processing;
Third: self conduct benchmark principle. Some small machining allowance, and finishing process of unity, to ensure the machining quality and productivity, and precision machining surface itself as a basic level.
Precision machining process
The main technical documents, is to guide the production
Machining workshop production planning, scheduling, the worker's operation, processing and quality inspection of the parts, processing cost accounting, is based on procedure. In dealing with problems in production, but also often to process planning as a common basis. Such as processing quality accident, should be in accordance with the procedure to determine the relevant units and personnel responsibilities.
Second, is the main basis of production preparation work
Workshop to produce new parts, the first to make the parts machining process planning, and according to the procedure for production preparation. Such as: in the process of new parts processing of the analysis and research of the key working procedure; Prepare the knife, clamp, measuring tool; Raw material and blank of purchasing or manufacturing; Purchase of new equipment or old equipment modification, etc., should be carried out according to the process.
Three, is the basic technology of new machinery factory file
When new batch or large mechanical processing workshop, should according to the procedure to determine the required amount and type of machine tool and in the workshop layout, and then determine the area of the workshop size, power and hoisting equipment configuration and the type of work, technical level of workers required, quantity, etc.
