Used Machine Tool Sales
At J.S.
Peters Machinery Sales, we
specialize in the sale of used CNC
machines. With over 25 years
experience in the new and used
machine tool business, we know what
it takes to buy - sell - appraise
and liquidate used metal working
machinery.
High-tech
Machinery
Our
expertise is in the technology side
of the business - if it's 5-axis CNC,
late model, loading robots and the
latest technology, we know just what
that machine can do and where to
acquire it.
Applications Engineering
Our
approach to used machine tools is
unique in that we provide
applications and process solutions
rather than just used CNC machines.
Our customers rely on us for
applications engineering. We
assist our customers in defining the
process and the right used machine
tool for their specific application.

-
Travelling table design ensuring stability
and accuracy for decades -Programmed through
the Siemens 840D controller, allowing you to
grind various surface contours such as
cylindrical, parabolic, sine curves, crowns,
convex and concave, radius, tapers, angles
and multiple diameters -Siemens servomotors
offering variable speed, high accuracy, low
vibration and large torque also at low
speeds -SKF high precision ball screws for
X- and Z-axis ensuring smooth, accurate and
trouble free movements of the antifriction
covered table and wheel slide -SKF bearings
in heavy-duty design in head- and tailstock
ensuring smooth and trouble free rotation of
even extra heavy work pieces -Hydrodynamic
grinding wheel spindle ensuring no
vibrations and no wear as the spindle is
rotating on an oiled film. Runout less than
0.001 mm -All main components are made of
high quality castings from well-established
foundries. These are specially processed to
avoid any internal stresses in the material
ending up in machines that are entirely free
of vibrations -Simple, stable design with
very few movable components resulting in
next to no downtime at all do to mechanical
problems. Great savings on maintenance
costs, as maintenance is limited to cleaning
and lubrication alone |
