What is CNC Turning?
CNC (Computer Numerical Control) turning is a advanced precision machining process where a cutting tool removes material from a rotating workpiece to create cylindrical, conical, or curved parts. Known for its high repeatability, exceptional accuracy, and efficient production speeds, it is a cornerstone of modern manufacturing.
At JST, we leverage state-of-the-art CNC lathes and a seasoned team of engineers to master this technology. Whether for simple bushings or complex rotationally symmetric components, we transform your designs into tangible CNC turning parts that meet the most stringent standards.
