The RGD – Automatic Duplex Grinder & Groover

(800mm (31.5 inch) in diameter and in length to customer specification)

A large sized grinding and grooving machine suitable for those with a requirement to grind high quality rolls. The RGD provides an edge over the competition by enabling customers to accurately grind and groove rolls, (including cambered profiles) in one setup at an affordable price.

The RGD Series of Automatic Duplex Roll Grinders is an advanced grinding and grooving machine in one setup. The RGD series is supplied complete with a full range of industry standard roll grinding and grooving profiles. The RGD series offers great versatility. CNC controls give the user the ability to program complex profiles.

The high speed grinding and grooving heads are mounted with separate axes (X1 & X2), on the CNC controlled indexing table, giving fast and accurate change between fully automatic grinding and grooving.

The RGD series can be fitted with either a tungsten carbide grinding wheel or a large stone or vitrified grinding wheel on the spindle of up to 800mm (31.5 inch) in diameter. The series features a hydraulically powered tailstock traverse and quill movement, making the loading and unloading of large components quick and easy. The two X-axes travel on a separate set of linear rails to the headstock / tailstock. This allow for the fitting of steadies to support heavy rolls.

The RGD series comes with a full range of industry standard grinding profiles and grooving patterns, including cambered (crown) rolls.

Extremely simple to use via the touch screen control panel, production profiles can be recalled from memory or quickly loaded from bar code. Operator training requirements are minimal as the fully automatic production is fast, accurate and consistently high quality, first time and every time. The RGD features a moveable pendant that allows the operator to position the control station anywhere along the traverse range. This allows the operator to have all the controls available within easy reach while at the same time as observing the grinding process, in a safe environment behind a clear macrolon window.

Like HNC’s other machines the RGD series can be switched between sixteen different languages at the touch of a button. Each machine is fully automatic and comes complete with a fully enclosed interlocked guarding system and complete dust extraction tube ready to connect to a dust extractor.
