What Format of Drawings Are Required for CNC Machining Parts?

When customers submit their requirements, they typically provide part-related 2D and 3D drawings in the form of technical documents. However, simply providing drawings is not sufficient. The drawings often need to include the following parameters: technical specifications, material, quantity, tolerances, post-processing requirements, and so on. Not all drawings can provide all the required information, so it is necessary for the machining factory to communicate with the customer again. If certain processes cannot be achieved, multiple discussions may be needed. Only after understanding all the customer's requirements can the machining factory provide timely and accurate quotations.

Drawing formats for precision machining of mechanical parts:

1) File format of 2D drawing: DWG, PDF, JPG (with technical specs, material, quantity, tolerance, surface treatment and special requirements indicated)

2) File format of 3D model: STEP, IGS (intuitive display size and structure of the product intuitively, used for programming)

When a shop engages in precision machining, it should not only meet the technical requirements of customers' workpiece machining but also focus on improving production efficiency and worker productivity. This approach ensures the ability to provide customers with more cost-effective and lasting services. How Fujian Meta Technology Co., Ltd is working on the process of precision part machining?

Firstly, upon receiving the customer's drawings and machining requirements, it is necessary to select suitable CNC machine tools and develop several economically viable machining process plans.

Secondly, an appropriate machining plan for precision CNC/mechanical part manufacturing is formulated. The drawings of the parts to be machined are analyzed, and suitable machining technologies are applied to process the parts.

Selection of material hardness is another important consideration. In some cases, higher material hardness is preferred. However, it must be within the hardness requirements of the machined components. The material should have moderate hardness, at least lower than the required hardness of the components. Therefore, the fundamental principle is to pay attention to the material density before machining.

In high-precision part machining, the critical aspect lies in the development and design of the process flow. The steps involved in part machining, including the selection of reference points, choice of machining tools, selection and installation of fixtures, determination of machining strategies, and process parameters, all have a significant impact on product quality.

During high-precision part machining, it is also crucial to emphasize comprehensive quality inspection. Fujian Meta Technology Co., Ltd is equipped with a complete set of precision machining equipments, CNC machine tools and inspection devices. With over 25 years experience in precision machining, we strictly control product quality and provide one-stop services.
