Frequently Asked
Questions
Everything you need to know about our CNC machining capabilities, material options, quality control, and order processing. If you can't find your answer here, our engineering team is ready to help.
Contact Support1. What are your standard tolerances for CNC machining?
Our standard CNC machining tolerance is ±0.05mm (±0.002") for most metals and ±0.1mm (±0.004") for plastics due to thermal expansion.
However, for critical aerospace and medical components, we routinely hold ultra-tight tolerances down to ±0.005mm. Please explicitly state your GD&T requirements on your 2D drawings when submitting an RFQ, and our engineers will verify manufacturability.
2. What materials do you machine?
We stock and machine a massive variety of industrial-grade raw materials, fully certified with MTC 3.1 tracebility:
- Metals: Aluminum (6061/7075), Stainless Steel (304/316L/17-4PH), Titanium, Inconel, Brass, Copper, and various Alloy/Tool Steels.
- Plastics: High-performance polymers including PEEK, Ultem (PEI), Delrin (POM), PTFE (Teflon), Polycarbonate, and Acrylic (PMMA).
If you require a custom alloy or specific medical-grade plastic, please let us know.
3. How do you guarantee part quality and compliance?
We operate under a strict ISO 9001 certified quality management system. Our advanced metrology lab is equipped with Zeiss Coordinate Measuring Machines (CMM), Optical Comparators, and Spectrometers.
We eradicate supply chain risk by offering complete transparency: First Article Inspection (FAI) reports, Material Test Certificates (MTC 3.1), and Outgoing Quality Control (OQC) documentation are available for every shipment upon request.
4. What post-processing and surface finishes do you offer?
To streamline your supply chain, we offer a comprehensive suite of in-house surface finishing services.
Popular treatments include: Type II & Type III Hardcoat Aluminum Anodizing, Bead Blasting for matte aesthetics, Electroless Nickel Plating, Black Oxide, Powder Coating, and Vapor Polishing for optically clear plastics.
5. Will my Intellectual Property (IP) and designs be secure?
Absolutely. We treat your Intellectual Property with the utmost confidentiality. We operate under strict Non-Disclosure Agreements (NDAs) for all our clients prior to file transfer. Furthermore, our digital infrastructure restricts CAD file access solely to necessary programming engineers, and our production facility is fully access-controlled.
6. What CAD file formats do you accept for quoting?
To provide the most accurate pricing and free DFM (Design for Manufacturability) analysis, we prefer native 3D CAD files.
Accepted 3D formats: STEP (.step / .stp), IGES (.igs), and Parasolid (.x_t).
If your part requires specific tolerances, threads, or surface finish callouts, please also upload a 2D PDF drawing alongside your 3D model when you request a quote.
