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 -The machine is
operated through the control panel and hand-
and finger wheels on the apron. Table
movement can be alternated between single
and continuos operation. Both table and
wheelslide are regulated with infinitely
variable speeds -The machine is designed for
high precision grinding of straight
cylindrical parts, small tapers and multiple
diameters -Table and variable headstock
rotation have a digital read-out as
standard. As an option the machine can be
equipped with automatic infeed. -Siemens
headstock servomotors offering variable
speed, high accuracy, low vibration and
large torque also at low speeds -Extremely
reliable hydraulic system for movements of
table and wheelslide ensuring the ground
surface will be the same all over the
workpiece -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 |
