We’re in the aerospace sector, so machining precision is absolutely critical for us. PCBasic helped us manufacture a batch of titanium alloy turbine housings, with tolerances consistently held within ±0.005mm. They even took the initiative to optimize the toolpaths, cutting our machining time by about 18%. During first article inspection, their engineers were on-site and provided the test report immediately. That level of professionalism gave us real confidence. We’ve already renewed our annual contract with them.

PCBasic turned out to be the right choice for our medical-grade parts. They machined our 316L stainless steel components to a mirror finish that fully met ASTM F138 standards. Surface roughness reached Ra 0.2μm, better than any vendor we’ve worked with before. Their Class 100,000 cleanroom and batch-level material traceability helped us pass the FDA audit smoothly. We’ve already recommended them to others in the industry.

We’re developing collaborative robots, and our part designs change pretty frequently. It’s hard to find a CNC factory that can keep up—but PCBasic really delivered. They offered 24-hour rush jobs and even set up video calls with us after every G-code update to double-check everything. One of the latest 7075-T6 harmonic reducer housings they made ran through 48 hours of stress testing with zero issues. The precision met all our lab specs.
