Where waste generates steam

This year's company outing took the employees in the morning to Perlen to the ultra-modern waste incineration plant "Renergia". After lunch at the restaurant Perle, man and woman could enjoy themselves in the most wonderful summer weather on the "Mostelberg", Sattel Hochstuckli.

Studer S33 – Cylindrical grinding with loading portal

It’s a particular concern of GROB AG to fulfil – as far as possible - its customer requirement into our own production facilities. Therefore, through the acquisition of the machine Studer S33 the necessary grinding capacity has been increased. The S33 is a CNC controlled universal cylindrical grinding machine for small to medium sized parts into individual and series production. Complex parts can be ground in one setting. This is possible thanks to the grinding head with two spindles and to the driven synchronous tailstock, which doesn’t need a separately slaving device.  Workpiece weight max. approx. 8 kg Length of parts 20 – 312 mm Part Ø 6 – 160 mm Grip Ø 6 – 60 mm Autonomy / workpiece magazine max 50 parts  

CTX alpha 500 from DMG

GROB AG has been using an additional DMG MORI machine in its turning shop since April 2015. The CTX alpha 500 is a top-quality and highly valuable addition to the company's machinery. It now also has the ability to manufacture turned and milled parts that are highly accurate on both sides in one clamping process. This investment complements the Köpfer hobbing machine, on which gears can be positioned according to a surface, a hole or an edge.
