company news about How can customers prepare appropriate drawing files?

In CNC machining, providing clear and accurate drawing files is the first step to ensure efficient production and precise delivery. Common 3D drawing formats include STEP (.step/.stp) and IGS (.igs/.iges), which are suitable for modeling, path programming and interference detection, and can visually display the geometric structure of the part. The commonly used 2D drawing formats such as DWG and PDF are mainly used for marking detailed dimensions, tolerances, tolerance grades, thread specifications and technical requirements.
We suggest that customers provide both 3D models and 2D drawings when submitting inquiries or placing orders. The 3D models facilitate our understanding of the overall shape and structural relationships, while the 2D drawings are used to guide the processing and inspection process, ensuring that the accuracy meets the expected standards.
Furthermore, in the drawings, it is advisable to clearly indicate: the type of materials, the surface treatment methods, special requirements (such as anodizing, electroplating, heat treatment, etc.) as well as the tolerance range of key dimensions. If only screenshots or blurry drawings are provided, it may lead to misunderstandings and delays in the delivery schedule.
If you are unsure whether the current drawing format is suitable, please feel free to contact our engineering team at any time. We will provide you with professional advice and format optimization support to help you complete each precision part efficiently.
