New ATRUMP
"M" Class
Vertical Machining Centers
|
Top of the
line engineering yields 2 different lines of machinery.
The appearance of Atrump's E series and M class Vertical Machining Centers
is very similar, and for good reason. For their M class machinery, Atrump
demanded the best of everything. The best accuracy, the longest machine tool
life, the largest table weight, the easiest to keep clean, lube and maintain.
Atrump required that their M class machines be capable of 24/7 production
under very rigorous conditions.
Atrump's E series machining centers benefit from the same expensive engineering
developed for their M class machines. Cost savings are achieved by reducing
the overall weight of each casting to lower material and shipping costs.
Since not everyone needs a big horsepower, higher speed spindle these features
are optional in the economy E series machines. The same applies to full machine
enclosures. Many shops prefer an open configuration but for those who desire
it, full enclosures are optionally available.
Atrump's M class of vertical machining centers is truly top of the line and
far less costly than the comparable Japanese machining centers. See firsthand
what makes Atrump's M class the best value in production cnc machining centers.
