Our standard lead time for CNC machined parts is 5-10 business days, depending on complexity, material availability, and order quantity. For simpler parts or rush orders, we offer expedited services that can deliver parts in as little as 3 business days. During the quoting process, we'll provide you with a specific lead time estimate for your project.

We accept industry-standard 3D CAD file formats including STEP (.stp, .step), IGES (.iges, .igs), SolidWorks (.sldprt), Solid Edge (.par, .asm), AutoCAD (.dwg, .dxf), and more. For best results, we recommend using STEP or IGES formats, as they are widely compatible and preserve model integrity. If you have 2D drawings, please include them alongside your 3D models for dimensional verification.

Our standard tolerances for CNC machined parts are ±0.125mm (±0.005"). For more critical dimensions, we can achieve tighter tolerances of ±0.025mm (±0.001") on specific features when required. Tolerance capabilities may vary based on material, part geometry, and feature size. Please specify any critical tolerances in your design files or notes when requesting a quote.

We offer a wide range of surface finishes for both metal and plastic components, including:

• As Machined: Standard finish directly from CNC machining
• Bead Blasting: Uniform matte finish that hides tool marks
• Anodizing: Protective oxide layer for aluminum parts (Type II or Type III, various colors)
• Powder Coating: Durable and attractive colored finish for metals
• Polishing: Various degrees from satin to mirror finish
• Passivation: Chemical treatment for stainless steel to improve corrosion resistance
• Black Oxide: Decorative black finish for steel parts

Custom finishes may also be available upon request. Please specify your finishing requirements when ordering.

Yes, we offer design for manufacturing (DFM) feedback as part of our service. Our engineering team reviews every design and provides suggestions to optimize your parts for CNC machining or sheet metal fabrication. This can include recommendations for:

• Improving manufacturability
• Reducing costs
• Enhancing functionality
• Optimizing material selection
• Addressing potential issues before production

For more comprehensive design assistance, we also offer engineering consultation services where our team can work with you from concept to final design.

We maintain strict quality control throughout our manufacturing process. Our comprehensive quality assurance program includes:

• First article inspection on all production runs
• In-process inspection during manufacturing
• Final dimensional verification using precision measuring equipment (CMMs, micrometers, calipers)
• Material certification verification
• Surface finish inspection and verification
• Documentation and traceability for all parts

For specialized requirements, we can also provide formal inspection reports, material certifications, or comply with specific quality standards as needed.
