Summit Super 20-4 & 24-4
Series Engine Lathe |
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, this lathe turns 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 eliminating the
simultaneous engagement of the feed and threading motion, place 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 16-24" Series Lathe greater radial and thrust capacities ensuring very precise
turning capabilities.
Available in 60", 80" and 120" 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.
