What Drawings Are Required for Precision Machining of Mechanical Parts?
Table of Contents
When customers place an order, they typically provide both 2D and 3D drawings to specify the required parts. However, simply submitting drawings is not enough. These drawings should clearly include key information such as technical specifications, material types, quantities, tolerances, surface finishes, and any post-processing requirements. In many cases, the provided drawings may lack some of these critical details. Therefore, the machining factory must communicate closely with the customer to clarify all requirements. If certain processes are not feasible, further discussions are necessary. Only after fully understanding the customer’s needs can the factory provide an accurate and timely quotation.
1.Precision mechanical parts processing drawing format:
Two-dimensional drawing file format: PDF or DWG (reflecting the technical parameters, materials, quantities, tolerances, post-processing and other requirements)
Three-dimensional drawing file format: STEP or IGS (to facilitate a more intuitive look at the structure of the product, size, etc., for programming).
Machinery processing plant in the precision processing, not only to ensure that the workpiece to meet the technical requirements put forward by the customer, with the corresponding performance, but also to focus on improving production efficiency and worker efficiency. Only in this way can they provide customers with services that are both affordable and effective in the long term.
2.Shenzhen high precision parts processing
Next, SzCrealink will provide an introduction to the general processing workflow of a high-precision parts manufacturer in Shenzhen.
First of all, after receiving the customer’s drawings and processing requirements, before the formal start of precision machining, to select the appropriate CNC machine tools, and to develop several sets of economic and efficient machining process program.
Next, you need to carefully analyze the part drawings, clear processing content, and select the appropriate processing technology.
Then, the choice of material hardness should be considered. Although some occasions the higher the material hardness the better, but also have to meet the hardness requirements of machining parts. Usually, the material hardness should be moderate, at least one grade lower than the hardness of the machine parts. Therefore, care must be taken to check the density of the material before machining.
In high-precision parts machining, the preparation and design of the process flow is crucial. This is because the procedural steps of parts machining, including the selection of datums, the selection of machining tools, the selection and installation of fixtures, as well as the machining strategy and the determination of process parameters, all affect the quality of the product.
