CNC turning can finish short runs of 1-10 pcs parts or high-volume orders of over 1,000 pcs at a fast speed without losing the precision. With our robust lathes and live tooling, we can bring out more complex features, such as slots, grooves, threaded holes and flats, at the most competitive prices and with a fast lead time. The tolerance of our CNC turning can reach at 0.005mm and gets tighter after surface grinding.
Our traditional and powerful lathes can cut out your precision parts with cylindrical features at a fast speed and requires relatively low start-up cost. Additional surface finishes can be provided by our post-processing services.
Winmi’s lathes equipped with live tooling combine the advantages of both milling and turning. This allows us to produce various and intricate features, including flats and radial and axial holes.
All raw materials are sourced from suppliers that have been cooperating with us for years.
We conduct strict inspections to make sure we produce quality parts.
