CNC Machining FAQ
CNC machining stands for Computer Numerical Control machining, a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. This process allows for highly precise control over complex machinery such as grinders, lathes, mills, and routers, enabling the automated production of intricate parts that meet exact specifications with minimal human intervention.
Unlike manual machining, which requires live operators to prompt and guide the commands of machining tools, CNC machining relies on digital instructions derived from a Computer-Aided Design (CAD) file. After a CAD sketch is developed, a computer converts it into numbers, and those numbers control the machine’s movements.
The benefits of CNC machining include:
High Accuracy and Precision: CNC machines operate with high precision and consistency, making them ideal for producing complex parts with tight tolerances.
Repeatability: Due to its computerized nature, CNC machining can produce numerous parts with exact uniformity, even over long production runs.
Efficiency and Speed: CNC machines can operate 24/7 with minimal downtime, significantly speeding up production compared to manual machining.
Flexibility: Changing the specifications of a part is as simple as updating the CAD file, making CNC machining highly adaptable to design changes.
Production Process: CNC machining is a subtractive manufacturing process where material is removed from a solid block using various cutting tools to achieve the desired shape. It’s well-suited for metal and plastic parts and is known for its precision and ability to produce complex geometries with tight tolerances. In contrast, 3D printing, or additive manufacturing, builds parts layer by layer from 3D model data, which allows for the creation of complex and intricate designs that would be difficult or impossible to achieve with traditional manufacturing methods. 3D printing is versatile in material choice, including plastics, metals, and composites, making it ideal for prototypes, end-use parts, and complex geometries.
Accuracy and Finish: CNC machining typically offers higher precision and better surface finish compared to 3D printing. CNC machined parts have tight tolerances and a smooth surface, often requiring minimal post-processing. On the other hand, 3D printed parts may show layer lines and require additional finishing processes to achieve a smooth surface. The precision of 3D printing has been improving, but it can vary depending on the technology (e.g., FDM, SLA, SLS) and the material used.
Choosing the Right Method: The choice between CNC machining and 3D printing ultimately depends on the specific requirements of the project, including material, precision, surface finish, and cost. CNC machining is the go-to for high precision and larger volumes, whereas 3D printing offers unparalleled flexibility in design and faster turnaround times for prototypes and small batches.
Absolutely. Prototyping is an essential step in the manufacturing process, especially when developing new products or parts. It allows you to test the design, functionality, and compatibility of your part before moving forward with larger production quantities, ensuring that any necessary adjustments can be made to avoid costly errors in the full production run.
Design Submission: You begin by submitting your design files. We accept various formats, and our team is ready to work with you to ensure your design is optimized for manufacturing.
Material Selection: Choose from a wide range of materials suitable for your prototype, considering the final application’s requirements.
Manufacturing: We use the same state-of-the-art CNC machining equipment for prototyping as we do for full production runs, ensuring your prototype meets the high standards required for your final product.
Quality Assurance: Each prototype undergoes a thorough inspection to ensure it meets your specifications and our quality standards.
Feedback and Revision: After evaluating the prototype, you can provide feedback or request changes. We can make the necessary adjustments to the design and produce another prototype, ensuring the final product is exactly as you need.
Benefits of Prototyping:
- Risk Reduction: Identify and address potential design or functional issues before they become costly in a full production run.
- Functionality Testing: Assess the performance of your design under real-world conditions to ensure it meets your requirements.
- Cost Savings: Making design changes during the prototyping stage is significantly less expensive than making them during or after full production.
- Time Efficiency: Prototypes can be produced quickly, allowing for rapid iteration and development cycles, speeding up the time to market.
For CNC machining projects, the precision and quality of the final part greatly depend on the detail and accuracy of the submitted design files. To ensure the best outcomes, we accept a variety of file formats that cater to both 2D and 3D designs. Understanding the file formats we accept will help streamline the submission process and facilitate effective communication between our design and manufacturing teams.
Accepted 2D File Formats:
- DXF (Drawing Exchange Format): Ideal for laser cutting, plasma cutting, and waterjet cutting projects. DXF files provide us with the 2D outline of your part.
- DWG (Drawing): Commonly used for 2D drawings or basic 3D designs. Originating from AutoCAD, DWG files are widely used in engineering and architectural projects.
Accepted 3D File Formats:
- STEP (Standard for the Exchange of Product model data): A widely supported file format that contains 3D models in a standardized format, making it ideal for sharing with CNC machining services.
- IGES (Initial Graphics Exchange Specification): Similar to STEP, IGES files are used for exchanging 3D models between different CAD systems.
- SLDPRT (SolidWorks Part File): The native file format for SolidWorks, containing 3D design data including the geometry and feature information of a single part.
- PDF (Portable Document Format): While not ideal for manufacturing purposes, PDFs containing drawings can be useful for quoting and initial discussions, provided they include relevant dimensions and tolerances.
For the Best Results:
- Include Detailed Information: Along with your files, providing detailed information about material specifications, surface finish requirements, and any critical tolerances is essential.

Understanding the timeline for your CNC machining project is crucial for planning and ensuring your product reaches the market or your production line on time. Our lead time for CNC machining projects is determined by several factors, including project complexity, quantity, material availability, and our current production schedule. Here’s a general guide to help you understand what to expect:
Standard Lead Times:
Prototypes and Small Batches: For prototype projects or small batch production, lead times can range from 3 to 7 business days after order confirmation and receipt of final design files. This timeframe allows for any necessary setup, machining, and post-processing work.
Medium to Large Production Runs: For larger quantities, the lead time can extend from 2 to 4 weeks. Larger projects require more time for material procurement, machining, and quality control processes to ensure every part meets your specifications.
Factors Affecting Lead Time:
Design Complexity: Complex parts with intricate features may require additional machining time and multiple setups, extending the lead time.
Material Selection: Availability of the chosen material can impact lead times. Common materials like aluminum and steel typically have shorter lead times compared to exotic or less commonly used materials.
Finishing Requirements: Additional surface treatments or finishing processes such as anodizing, plating, or painting will add to the lead time.
Quantity: The number of parts ordered affects the lead time, with larger quantities necessitating longer production schedules.
Current Workload: Our production capacity at the time of your order placement can also influence the lead time. We operate on a first-come, first-served basis but always strive to accommodate urgent requests.
We understand that some projects have tight deadlines. Depending on our current workload and the specifics of your project, rush orders may be available at an additional cost. Please discuss your needs with us directly to see how we can best accommodate your timeline.
