From 1 to 100,000+ pieces, covering rapid prototyping through mass production.
We provide custom CNC machining services for high-precision parts, backed by advanced CNC equipment and an experienced machining team. From prototypes to full-scale production, we manufacture custom parts to your exact specifications with tight tolerances, consistent quality, and reliable lead times.
PCBgogo delivers custom CNC machining for precision parts across new energy vehicles, photovoltaics, semiconductors, and medical equipment, along with established sectors such as industrial machinery and chemical processing. Parts are held to tight tolerances under full-process quality control with dimensional inspection, keeping quality consistent from the first prototype to full production. Fast, dependable lead times and responsive engineering and after-sales support move every project from quote to on-time delivery.
Precision CNC machining for industrial fixtures, hydraulic valves, and transmission bases in steel, aluminum, and engineering plastics. Multi-axis machining holds tight tolerances in fewer setups, delivering wear-resistant, dimensionally stable parts for long-running automated machinery.
Our compliant CNC machining makes surgical tools, dental implants & imaging device parts. Micron-level precision on biocompatible titanium and stainless steel creates burr-free, sterilizable components. Full traceable QC meets strict medical standards for custom minimally invasive instrument accessories.
We process aerospace aluminum, titanium, and superalloy curved parts, including aircraft brackets and satellite bases. Our 5-axis single-setup machining minimizes thin-wall deformation while achieving aviation-grade accuracy, delivering lightweight, robust prototypes and aerospace structural components.
Precision machining of mechanical and power components for automotive systems, including transmission and chassis parts. Wear- and pressure-resistant materials withstand rigorous, long-lasting working conditions, with consistent dimensional accuracy across every batch.
Ultra-precise micro CNC machining for phone frames, laptop cooling fins and wearable casings. Fine polishing and micro-hole milling deliver flawless surfaces on lightweight aluminum and magnesium alloys, supporting fast iterative prototypes and bulk electronic structural parts.
Robotics push accuracy and weight to the limit. We machine lightweight aluminum joints, actuator housings, and structural frames with the tight tolerances that motion systems depend on. Rapid iteration support helps you refine mechanical designs and move from prototype to deployment faster.
Our machines custom metal and plastic parts to tight tolerances, from prototypes to production runs. With multi-axis milling, CNC turning, and full-process quality control, we turn your CAD files into accurate, production-ready parts.
