FAQ
A wide variety of materials can be processed, including metals (like aluminum, steel, stainless steel, titanium, brass) and plastics (such as ABS, polycarbonate, nylon, PEEK). The best material choice depends on the part’s application, required properties, and budget.
CNC machining is known for its high precision and ability to hold tight tolerances, often down to +/- 0.005mm (0.0002 inches) or better, depending on the specific process, material, and part geometry. Clearly specify critical tolerances on your technical drawings.
We typically require 3D CAD files in standard formats like STEP (.stp/.step), IGES (.igs/.iges), Parasolid (.x_t), or SolidWorks (.sldprt) for accurate quoting. Accompanying 2D PDF drawings are also very helpful for indicating tolerances, finishes, and other critical details.
Lead times vary depending on factors like part complexity, quantity, material availability, and current shop capacity, but often range from 1 to 4 weeks. Requesting a quote with your complete design files will provide the most accurate delivery estimate.
Yes, various surface finishing options are available to enhance appearance, durability, or corrosion resistance, such as anodizing, bead blasting, powder coating, painting, polishing, and plating. Please specify your required finish when submitting your request for a quote.
To provide the best quote, please supply your 3D CAD model, a 2D technical drawing (if available), the desired material, required quantity, specified tolerances, and any surface finish requirements. Clear communication ensures your parts meet expectations.
CNC Milling uses rotating multi-point cutting tools to remove material from a stationary workpiece, ideal for creating complex shapes, slots, holes, and flat surfaces. CNC Turning involves rotating the workpiece against a stationary single-point cutting tool, primarily used for producing cylindrical, conical, or round parts.
