CNC Turning Service
Precision CNC turning for cylindrical components, from micro-precision parts to large industrial shafts.
Overview
PiPrecision specializes in precision CNC turning for cylindrical components, from micro-precision medical implants to large industrial shafts. Our lathe department combines Swiss-style sliding headstock machines for small, complex parts with powerful CNC lathes for larger diameter workpieces.
Our multi-axis turning centers with live tooling capabilities produce complex parts complete in one setup — reducing handling, improving concentricity, and lowering costs. From simple bushings to intricate valve bodies with internal features, we deliver precision-turned components that meet the most demanding specifications.
With 99% customer satisfaction and a 0.26% return rate, our quality systems ensure every part is right the first time.
