We specialize in working with an extensive range of engineering materials including aluminum alloys (6061, 7075, 5083), stainless steel grades (303, 304, 316, 430), premium titanium alloys (Grade 2, Grade 5), brass, copper, Inconel superalloys, high-performance polymers like PEEK and Delrin, and precision engineering plastics. Each material selection is optimized through our design-for-manufacturability process to ensure optimal performance, cost-efficiency, and production speed while maintaining our commitment to industry-leading quality standards and tight tolerance specifications.
From initial concept and design review through comprehensive DFM (Design for Manufacturability) analysis, sophisticated CAD-driven production, precision machining operations, rigorous quality control with CMM verification, to final inspection and global shipping logistics, our team provides full-service manufacturing support at every critical stage. We maintain ISO 9001:2015 and AS9100 aerospace certifications, ensuring your components meet the most demanding industry specifications. Our rapid 3-day turnaround capability combined with our no-minimum-order-quantity policy makes us ideal for both prototype development and production manufacturing.
Our advanced CNC programming capabilities support multiple file formats including STEP, IGES, DWG, and native CAD files. We offer comprehensive documentation, material traceability, and full manufacturing records for complete supply-chain transparency. Our quality assurance protocol includes precision surface finishing options and measurements (Ra values), dimensional verification using advanced CMM technology, and comprehensive testing documentation available for all finished components.

Frequently Asked Questions
What tolerances can you achieve with CNC machining?
We regularly achieve tolerances of ±0.005 mm (±0.0002") on critical dimensions. Standard production tolerances are typically ±0.025 mm (±0.001"). Tighter tolerances are possible on specific features and materials depending on design requirements.
What is your minimum order quantity?
We have no minimum order quantity. Single-piece custom machining is welcome, as are prototype runs, small batches, and full production orders.
What file formats do you accept for CNC machining?
We accept STEP, IGES, DWG, PDF, and native files from SOLIDWORKS, AutoCAD, FreeCAD, and other CAD software. Please include all dimensions, tolerances, material specs and surface finish requirements.
What surface finishes are available after CNC machining?
Standard CNC produces Ra 0.8–3.2 µm depending on tooling and material. Additional finishing — polishing, anodising, plating, powder coating — is available through our surface finishing department.
What is your typical lead time for CNC machining?
Prototypes: 3-5 business days from approval. Small production: 1-2 weeks. Larger quantities: 2-4 weeks depending on complexity. Rush orders accommodated with expedited fees.
Do you offer material traceability and certifications?
Yes. Material certificates of conformance (CoC), heat lot numbers, chemical composition, CMM reports and manufacturing records. ISO 9001:2015 and AS9100 certifications.
