Frequently asked questions
What Tolerance Does XC Machining Hold for Automotive CNC Machined Parts?
Standard tolerance: ±0.005 mm on 5-axis CNC machined aluminum and steel automotive parts. ±0.01 mm on 3/4-axis CNC parts. Injection molded parts: ±0.05 mm standard; ±0.02 mm tight tolerance. Sheet metal (laser cut and bent): ±0.1 mm per ISO 2768-m. All critical dimensions verified by CMM; dimensional report provided with first article inspection (FAI) on new part numbers.
Can XC Machining Produce Both Prototype and Production Automotive Parts?
Yes. XC Machining produces: CNC machined aluminum prototypes (1–500 units, no tooling, 3–15 day lead time) for design validation and crash testing; vacuum cast PA polyurethane samples (5–25 units, 5–7 days) for assembly fit-check; and injection molded production parts (steel mold, PA66-GF or PP, 500–500,000+ units, 15–35 day tooling lead time) for interior trim, HVAC, and connector housings.
What EV Electric Vehicle Parts Does XC Machining Manufacture?
XC Machining EV manufacturing: CNC machined aluminum 6061-T6 battery enclosure frames (±0.01 mm, anodized); laser-cut and bent aluminum 5052-H32 battery module housings (±0.1 mm); injection molded PA66-GF30 structural battery brackets and connector housings (±0.05 mm, steel mold); CNC turned motor shaft components (±0.005 mm, Ra 0.8 μm); and powder-coated aluminum motor housings (60–120 μm, 500-hour salt spray).
What Is the Lead Time for Automotive Parts from XC Machining?
CNC machined automotive prototype: 3–7 business days (aluminum, simple geometry) / 7–15 days (steel 4340 or 5-axis complex geometry). Injection mold tooling + first production: 15 business days (aluminum mold, 200–5,000 units) / 25–35 business days (steel mold, 5,000+ units). Sheet metal laser-cut parts: 3–5 business days. DFM review and quote: within 12 hours of CAD file upload.
Does XC Machining Offer SPC and Quality Documentation for Automotive Production Runs?
Yes. XC Machining applies statistical process control (SPC) on production automotive batches — measuring key dimensions at every 50th CNC part or every 100th injection molded shot and charting against control limits. First article inspection (FAI) with full CMM dimensional report is issued before every new production run. Material certificates (mill cert or resin CoA) and Certificate of Conformance (CoC) are provided with every shipment.
