Screw Machining Benefits

Tri Part’s screw machine department is optimal for high-precision, high-volume products. We machine a variety of stock sizes from 3/16” OD up to 2-1/4” OD. Our Wickman machines utilize six spindles, dropping completely finished machined parts every index of the machine producing high precision parts at a very fast pace. Cycle times can be as fast as 8 seconds or up to one minute depending on material or part geometry. Our machines also include threading spindles, slotting / broaching / milling / drilling attachments to speed production of your part. These machines are also equipped with pick off attachments to facilitate back side machining on the same machine. Special CNC equipped machines allow for drilling, milling, and single point threading all within one cycle of the machining process.
