CNC Machining — FAQ

  • What tolerances can TruPart achieve?

    TruPart achieves ±0.005mm on critical dimensions using DMG MORI 5-axis and CMM inspection. Standard precision is ±0.1mm.

  • What materials do you machine?

    Aluminum 6061/7075, stainless 303/304/316L, titanium Gr2/5, brass, PEEK, Delrin, Nylon, Inconel, tool steels.

  • What is typical lead time?

    Prototypes 5-7 business days. Production runs ship within 14 days DDP. Rush available.

  • Do you offer free DFM review?

    Yes. Engineers review designs within 48h at no cost. Typically saves 15-20% on manufacturing costs.

  • What is the minimum order quantity?

    No MOQ. Prototypes of 1-10 pieces and production runs of 10,000+.

  • How do you ensure quality?

    CMM inspection. measured values on critical dimensions. Free FAI included.

  • What surface finishes do you offer?

    Anodizing Types II/III, passivation, electroless nickel, powder coating, bead blasting, polishing. Ra 0.4μm.

  • How does DDP shipping work?

    We handle export, freight, customs, duties, and delivery. One invoice. 4-6 business days to EU and US.

  • What industries do you serve?

    Medical, aerospace, automotive, semiconductor, valve/pump, automation, machinery.

  • How do I get a quote?

    Email STEP/IGES/PDF to sales@trupartprecision.com or WhatsApp +86 137 1278 3205. Engineering review and quote within 48h.

  • What file formats do you accept?

    STEP(.stp), IGES(.igs), SolidWorks(.sldprt), AutoCAD(.dwg/.dxf), Parasolid(.x_t), PDF. STEP preferred.

  • Can you machine customer-supplied materials?

    Yes. Contact us for feasibility assessment and pricing.

  • What payment terms do you accept?

    We accept T/T bank transfer, PayPal for smaller amounts, and L/C for large production orders. Net 30 terms available for established clients.

  • Do you sign NDAs or keep my drawings confidential?

    Yes. All customer drawings, files and IP stay confidential under NDA on request. We never share or reuse your designs.

  • How are parts packaged for shipment?

    Parts are individually protected and packed per your spec — foam inserts, export cartons, ESD bags for electronics and moisture barrier where needed. Packaging photos available on request.

  • Do you offer better pricing on repeat orders?

    Yes. Once tooling and processes are established, repeat orders get faster lead times and volume-based pricing.

  • Can you handle rush orders?

    Yes. We reserve capacity for rush prototypes and urgent repairs — 24-48h turnaround is possible on simple parts.

  • Can I get a sample before production?

    Yes. First Article Inspection (FAI) is free on every new part; sample batches are quoted at prototype rates and shipped fast.

  • Why are your prices lower than local suppliers?

    Lower labor costs, DMG MORI machine efficiency and batch scheduling — while keeping ±0.005mm tolerance, CMM inspection and free FAI. Customers typically cut costs 30-50% vs European suppliers.

  • Do you only make standard parts?

    No — we make custom parts only, machined from your drawings. No stock products, no minimum order. Any size, any material, any quantity.
