CNC turning service
Our extensive network of advanced CNC turning experts enables us to source top-quality components in over 50 diverse metals and plastics. With the capability to achieve tight tolerances as precise as ±.0008″, we ensure high-performing parts for your specific requirements.
What is CNC turning?
CNC turning is a manufacturing process that involves securing a blank onto a rotating chuck and eliminating material using fixed cutting tools. This technique is particularly suitable for creating parts that possess symmetry along their central axis. Turned parts are generally manufactured more efficiently (and at a reduced expense) compared to milled parts.
