The Clausing MA30 series large swing engine lathes are
engineered to allow the accurate and efficient machining of
large components. A wide range of optional accessories make
these machines suitable for most industrial applications,
including job shops, oil field, power utilities and ship
* 12 Geared Head Spindle Speeds allows optimum cutting speed
for a wide range of machining applications. Speed range from
12 to 1000 rpm.
* Spindle Motor - 15Hp for exceptional machining power.
* All gears are made from chromium molybdenum steel treated
wtih cementation and precision ground for long-life and
* One-piece cast iron bed from the ways to floor provides a
solid foundation to ensure maxium stability and rigidity
under heavy machining operations.
* 18" Bed Width, Hardened and Ground, support the saddle and
carriage assembly allowing superior positioning and
* Turcite `B' is fitted between saddle and bed to greatly
reduce friction and stick-slip for smooth operation and
superior surface finishes. The low friction Turcite also
minimizes bed wear and extends the life of the machine.
