FAQ
- What materials can be used in CNC machining?
- CNC machines can handle a variety of materials such as: Metals (aluminum, steel, titanium, brass, copper), Plastics (ABS, POM, nylon, acrylic), Wood and composite materials, Ceramics and more.
- What is the typical lead time for CNC machining?
- Lead times depend on the complexity of the part, the material, the required finish, and the production volume. Typically, CNC machining can take anywhere from a few days to a couple of weeks for a prototype or small batch, but larger orders may take longer. Normally 7 days for prototyping and 20 days for mass production shipment.
- What is the maximum size of a part that can be CNC machined?
- The size limitations depend on the specific CNC machine being used. Large-scale machines can accommodate parts up to several meters in length, while smaller machines are typically limited to parts around 1000mm in length or less.
- How much does CNC machining cost?
- CNC machining costs vary based on factors such as: Material choice, Part complexity, Machine time, Labor costs, Quantity (prototypes vs. mass production).
- What types of finishes can be applied to CNC machined parts?
- Common finishes include: Anodizing, Powder coating, Polishing, Painting, Bead blasting, Electroplating.
- Can CNC machining be used for prototyping?
- Yes, CNC machining is widely used for prototyping because it allows for the quick production of precise parts. It's ideal for low-to-medium volume production runs and allows engineers to test designs and make adjustments before mass production.
- Are the parts shown in your pictures available for direct purchase?
- All parts shown in our photos are examples of our past work and manufacturing capabilities, for demonstration purposes only. We do not sell these parts directly. We specialize in custom CNC machining, producing parts according to your own drawings, designs, or samples.
- What file formats do you accept for custom CNC machining?
- We accept common formats including STEP, IGES, STL, and DWG. For best accuracy, we recommend providing 3D models along with 2D drawings with clear tolerances and material specifications.
- Can you provide a sample before mass production?
- Yes. We can produce prototype samples first for your approval before starting full mass production. This helps verify the part's fit, function, and quality to ensure it meets your requirements.
- How do you ensure the quality of CNC machined parts?
- We conduct quality checks at every stage: first article inspection (FAI), in-process dimensional checks, and final inspection with tools like CMM and vernier calipers. We can also provide inspection reports, material certificates, and quality documents upon request.
- What shipping methods do you offer, and how long does delivery take?
- We ship worldwide via DHL, FedEx, UPS, TNT, or sea freight, depending on your order size and urgency. Standard air shipping typically takes 3-7 working days, while sea freight takes 25-45 days, depending on your location.
