The Last Word in High Performance Engine Lathes
The all new Clausing/Colchester 18" and 21" lathes follow in the steps
of the highly successful Clausing/Colchester 13" and 15" lathes which set
new standards for engine lathe performance with the introduction of electronically
variable speed spindle drives in 1989.
These two heavyweight machines offer the same key features which, combined
with the availability of constant surface speed cutting, offer prospective
users outstanding productivity gains over conventional engine lathes together
with a rugged construction designed to give years of lasting performance. |
