SUMMIT 20 and 24 Series Engine Lathes combine accuracy, simplicity and affordability to bring you a proven industry leader. Tested under the most demanding work conditions, these lathes turn rings around other lathes in their class. SUMMIT 20", and 24" Series Lathes have just the right amount of engineering to afford simplicity of operation, coupled with plain and simple rugged reliability. In addition, built in safety features with the safety interlock eliminate the simultaneous engagement of the feed and threading motion, placing these machines in a field of their own - unparalleled in performance.
A few of the outstanding features on the SUMMIT 20" and 24" Series Lathes are a cross ribbed headstock for added strength and stability, with anti-friction mounted shafts and dynamically balanced components; hardened and ground alloy steel gears, shafts and splines, and an oversized precision chrome alloy spindle with a big 4-1/8" thru hole that is mounted in double row angular contact thrust bearings and 2 double row roller bearings. These large spindle bearings give the 20" and 24" Series Lathes greater radial and thrust capacities ensuring very precise turning capabilities.
Available in 60", 80" ,120" and now 160" center distances, the SUMMIT 20" and 24" Series Engine Lathe feature hardened and precision ground bed ways on a heavy one-piece close grain cast bed that is fully ribbed for maximum stability and even thermal expansion. Standard on every machine is a quick-change gearbox for cutting Metric, Module, and Diametrical Pitch threads as well as standard American threads.
