Real-World Engineering Challenges & Delivered Solutions
Review selected custom component projects demonstrating our multi-axis CNC machining centers, automated turning, precision sheet metal fabrication, and metrology verification.
Custom 5-Axis Machined Laser Cavity Housing
Complex internal optical paths with multi-angled mounting faces requiring strict linear tolerances down to +/-0.005mm and zero internal stress distortion. Machined on high-speed FANUC 5-axis centers in a single setup; verified with 2D optical projector.
Precision Anodized Robotics Articulation Link
High strength-to-weight ratio requirement with thin-wall sections prone to machining chatter and tight bearing bore alignment. Engineered custom clamping fixtures on GMU800 center to distribute cutting forces; checked with calibrated plug gauges.
High-Vacuum Stainless Steel 316L Fluid Manifold
Burr-free micro-drilled fluid channels and sealing face flatness required for high-vacuum semiconductor environments. Specialized stainless steel tooling and thermal control during milling; 100% surface roughness and thread gauge inspection.
Swiss Turned Zero-Leakage Pneumatic Valve Stem
High-aspect-ratio slender turned shaft requiring concentricity within 0.008mm and zero tool marks on sealing surfaces. Executed on bar-fed Swiss sliding-head lathes in a continuous run; verified using Mitutoyo 0.001mm digital micrometers.
LiDAR Sensor Aluminum Enclosure & Heat Sink
High cosmetic aesthetic requirements combined with dense thin-fin heat dissipation structures and precise masking zones. Optimized cutter paths to prevent fin bending followed by uniform automated bead blasting and masked anodizing.
Precision Sheet Metal Equipment Chassis & Panel
Complex multi-bend enclosure requiring tight hole-to-bend positioning tolerances and clean corner welds. Precision CNC press brake bending with dedicated bend tooling and post-coating thread clearance checks for Pemnut hardware.
