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.

Features:
Three axes automatic grinder with small footprint.
Double V guide-ways are laminated with Turcite-B hand scraped to obtain smooth stick-slip free movements.
The traverse is guided by roller linear guides, with high precision ball-screws and driven by servo motor.
The Y-axis is also guided by roller linear guides, with high precision ball-screws and driven by servo motor.
The flanged cartridge type spindle is supported by 3 pairs of class 7 super precision angular contact ball bearings, preloaded and select-fitted into spindle cartridge.
The automatic re-circulating lubrication system supplies lubricant to all of the guide ways and lead screws as the machine operates.
The external independent hydraulic tank is located outside the machine to be easily accessible for maintenance. Driven by the proportional valve hydraulic system for easy speed adjustment in a range of 2~30meter/min for most surface grinding applications.
Standard oil cooler unit for hydraulic system. Prevents temperature rises and thermal deformation is reduced to a minimum.
An independent control box with an ergonomically designed panel offers a comfortable and convenient operation environment.
Control available in Fanuc, Siemens, Mitsubishi and Heidenhain.
