A New Generation of Variable Speed Engine Lathes
When Clausing/Colchester introduced the "15 inch" Lathe twenty years
ago, it set new standards of engine lathe specification and performance.
Now Clausing/Colchester sets the standards again with the introduction
of its all new Professional Series 15" VS Lathe.
An electronically variable speed spindle drive gives a better cutting
performance than many CNC lathes let alone other engine lathes. Precision,
power and durability, together with a host of innovative features are built
in to give years of lasting performance from this rugged machine.
Key Features
-
Heavy duty construction - over 20% heavier than previous models.
-
Wide bed giving high rigidity. Spindle speeds 25% faster than the previous
model.
-
Anti-friction linings on the carriage ways - minimal bedwear - longer machine
life. Field tested for over 10 years without failure.
-
Electronic, infinitely variable speed spindle drive -enables optimum cutting
speeds - faster cycle times - allows the full use of modern cutting tool
technology.
-
Wide spread of power - over 30 to 1 Constant Power Range. High power at
low speeds and high power at high speeds.
-
Built to Metric Standards throughout.
-
Low noise levels - less than 8OdBA at 40" envelope around machine.
Numerous Safety Features Including
-
Interlocked End Guard Door.
-
