CMM quality control in First Article Inspection (FAI) uses automated 3D coordinate measuring machine probes to verify intricate dimensions against drawing GD&T callouts by physically touching thousands of points on a part. The CMM Inspection Report compares measured values to nominal dimensions with upper/lower limit deviances, showing pass/fail states for every feature. At 6CProto, ISO

Functional automotive prototype machining validates engine and powertrain components by machining metal and polymer assemblies to exact tolerances, then stress-testing them under extreme vibration, heat, and fluid pressure. CNC machining with definitive materials like billet aluminum allows real-world validation before production, reducing development time and cost. What Is Automotive Functional Prototype Machining? Automotive functional prototype

Use wire EDM instead of CNC milling when you need sharp internal corners in thick, pre-hardened tool steel. CNC milling creates rounded internal corners due to rotary tool geometry and cannot cut hardened steel above ~40 HRC without excessive tool wear. Wire EDM uses non-contact electrical sparks to erode material, achieving micron-level tolerances and true

Chrome, nickel, and gold electroplating enhance industrial components with wear resistance, corrosion protection, and surface hardness. Hard chrome delivers extreme abrasion resistance; electroless nickel provides uniform thickness and chemical resistance; gold offers conductivity and corrosion immunity. These chemical and electrochemical deposition processes are critical for aerospace, medical, and automotive parts requiring extended service life. How

Mastering brass and copper CNC machining for high-conductivity electrical contacts requires managing pure copper's gummy ductility with specialized chip-breakers and high-pressure coolant, while using free-machining brass C360 for superior chip breakdown. Prevent oxidation through immediate lacquer or polymer coatings, regulated humidity storage, and cotton glove handling. At 6CProto, we balance conductivity with machinability to deliver

Export a clean, single-body STEP file (.stp/.step) with units set to millimeters, remove all hidden/suppressed features, and ensure no corrupt faces or open shells. This guarantees your automated DFM engine at 6CProto can quote instantly without manual repair. What Is the Best CAD Format for an Instant CNC Quote? The best format is STEP (.stp/.step),

A custom CNC heat sink improves enclosure cooling by adding precisely controlled surface area, better airflow paths, and a direct thermal path from hot components into the housing. In practice, the best designs balance fin height, fin spacing, material choice, and thermal interface quality so heat leaves the system fast without creating airflow blockage, vibration

For CNC enclosures, powder coating delivers the best overall protection with 60–100 microns thickness, superior scratch resistance, and infinite color options for outdoor/industrial use. Anodizing (Type II) provides a premium metallic look for aluminum-only enclosures with 10–25 microns thickness and excellent UV stability but won't hide surface imperfections. Plating (zinc/nickel) offers the lowest-cost sacrificial corrosion

High-precision aerospace machining requires AS9100 quality standard compliance, EN 10204 Type 3.1 material certificates with heat number traceability, stress relief cycles before final machining, and 100% CMM inspection tracking. Achieve ±0.005" tolerances on flight-grade parts manufacturing using 7075-T6 aluminum or Ti-6Al-4V with documented Mill Test Reports verifying chemical composition and physical properties. What Defines Flight-Critical

Prevent tool deflection in deep pocket CNC milling by limiting pocket depth to 3× tool diameter, using reduced-shank end mills, implementing trochoidal/plunge milling, applying high-pressure through-spindle coolant, and thread milling instead of tapping depths >2× diameter. For deep-hole tapping, use spiral-point taps with peck cycles, minimum 0.5× diameter clearance below thread, and thread milling for
