Slideways
Hand scraped vee and flat slideways are provided for both cast machine table
and wheelhead back slide. Turcite coated bearing surfaces, automatically
lubricated, assure low friction movement. Both axes are ball screw driven
and controlled by A.C. servo motors with air purged, linear scales.

Wheelhead - Universal (swivelling)
This wheelhead incorporates independent external and
internal wheelspindle drives. The hardened and ground
external wheelspindle can accommodate a grinding
wheel at either end. For normal cylindrical grinding
operations a 400 x 50mm wheel is mounted the left
hand side, whilst for face and some form grinding
operations a 300 x 25mm wheel can be mounted on
the right hand side. For ease of set-up when swivelling
the wheelhead, an airlift facility is provided. Further
options include Angle Head and twin ‘B’ or full ‘B’ axis
wheelheads both with Holroyd high precision worm &
wheel assemblies for infinitely variable rotation.
DESIGN & BUILD
Available with easy to use ‘Self Teach’ Touch Panel Technology or Operator
Friendly CNC with Windows® based software. Ultramat can accommodate
one off, batch or high volume production and will hold the tightest of tolerances.
Robust construction and designed with the ability to incorporate the latest
developments in gauging and autoloading ensure that Ultramat from Jones &
Shipman will fulfil your grinding needs.
Workhead and Tailstock
The live and dead single
spindle workhead contains
robust, high precision tapered
roller bearings for superior
stiffness.
A variable speed AC servo
drive to the spindle with
encoder ensures fast and
accurate spindle orientation.
The machine table slide
swivels for taper correction.
A high accuracy taper
correction tailstock can also
be provided as an option, if required. Thermal stability in the work area
is ensured by porting coolant through the structure of the workhead,
tailstock and on a plain spindle machine through the wheelhead.
