When delivering customer requirements, it is generally necessary to provide 2D and 3D drawings related to the parts in the form of drawings. Providing drawings alone is not enough. The drawings often need to reflect the following parameters: technical parameters, materials, quantities, tolerances, post-processing requirements, etc. Not all drawings can provide all the required information. Therefore, the machining factory needs to communicate with the customer again. If some processes cannot be achieved, multiple communications are needed, We can only provide timely and accurate quotations after understanding all the customer's needs.
Precision mechanical parts machining drawing format:
2D file format: PDF or DWG (reflecting technical parameters, materials, quantities, tolerances, post-processing requirements, etc.)
3D file format: STEP or IGS (for a more intuitive understanding of the product's structure, dimensions, etc., used for programming).
When precision machining is carried out by a machining factory, it is not only necessary to meet the technical requirements of the customer's workpiece processing, but also to pay attention to the improvement of production efficiency and worker work efficiency, so as to bring more economical and long-term effective services to the customer. So let Shenzhen Huiwen Intelligent Manufacturing Technology Co., Ltd. explain to you the general processing operation process of high-precision parts processing manufacturers in Shenzhen!
Firstly, upon receiving the customer's drawing processing requirements, it is necessary to select a suitable CNC machine tool and write several sets of economic and cost-effective processing plans before starting precision machining.
Then develop a suitable CNC/mechanical machining plan for precision parts, analyze the drawings of the parts to be machined, analyze the machining content of the parts, and adopt appropriate machining techniques.
Secondly, in the selection of material hardness, in some cases, the higher the hardness of the material, the better. However, it is limited to the hardness requirements of the machining parts. The material should be moderately soft and hard, at least one grade lower than the hardness of the parts. Therefore, the most basic rule is to pay attention to the density of the material before processing.
In high-precision part machining, it is important to write and design the process flow, because the program steps of part machining, the selection of benchmarks, machining tools, fixture selection and installation, as well as the determination of machining strategies and process parameters, affect the quality of the product.
