An award winning & patented concept involving a total rethink of the surface grinding process has resulted in Dominator a technically advanced Precision Production Surface, Profile and Creepfeed Grinder.
The absence of a reciprocating table and wheelhead column gives major benefits with respect to structural rigidity and machine dynamics.
Designed with the production environment in mind, Dominator has totally enclosed guarding and occupies a small footprint.
The Dominator is available in either 3, 4, 5 or 6 axis formats, controlled via a GE-Fanuc® Intelligent Terminal supporting a Jones & Shipman developed Windows® based software package.
Equally at home when Reciprocating or Creepfeed grinding, the Dominator will fulfil all your Batch or Production grinding needs.

With the new grinding machine model STEEL LINEAR both reciprocating and slow creep-feed grinding operations can be carried out so to obtain concave or convex profiles both crosswise and longitudinally. This machine can be equipped with supplementary devices such as side wheelheads and dividing heads for grinding any parts of complex configuration, which normally would require several set-ups. This eliminates problems concerning work-in-process and therefore increases the productivity of the machine. ROSA SYSTEM VII CNC (Siemens Sinumerik 840 Di) unit.
The table runs on preloaded crossed-roller monorails which prevent the negative stick-slip effect and offer a damping effect as to vibrations. The vertical axis and the cross axis are driven by ballscrews with double preloaded screw-nut, powered by AC brushless motors, whose motion is controlled by an encoder or, on request, by optical scales with millesimal resolution.
The standard power-rate of the wheel motor is 11 kW (available as an option up to 22 kW). Digital Linear motor for table axis (X): Fmax=6.500 Nm. Maximum cube which can be ground: 1500x750x600 (h)mm.

Diskus double surface lateral grinding machine with vertical spindle.
This machine model is a steel-welded, box-frame design with greater rigidity than a comparable portal machine. The two vertical , directly driven motor spindles with liquid cooling each have an output of 23 kW to 48 kW. They are attached to rolling bearing compact carriages which perform all feed and return motions with a precision screw drive.
The machine version required for this application can be used as a plunge cut as well as throughfeed grinding machine. A number of parts can be ground simultaneously with the planetary drive provided with controlled rotation. While they are fed to the grinding tools using the plunge cut process in a planetary gear which rotates around its own axis. Replacement of the transport plate allows the same machine to be used for throughfeed grinding.

With SATURN double-disc surface grinding, two vertical grinding wheels simultaneously grind the workpiece on its parallel outer surfaces. The grinding wheels are set against each other at a slightly conical angle, so that as it passes from top to bottom, the workpiece retains its final dimension only in the bottom section of the grinding path. Because the workpieces are fed vertically between the grinding wheels, the bearing weight of the workpiece does not affect the grinding result. What’s more, the
coolant can simply drain downwards together with the removed material. The SATURN range comprises three
different machining processes:
- Rotation process
- Parallel grinding with linear through-feed
- Pendulum grinding
