OverHead® Gantry - our flexible space-saving option

CNC Gantry Milling Machine, available in four different sizes for different process areas!

Maximum functionality with minimum space requirements is the motto of the OverHead Gantry M. The basic machine can be optimally configured for many sectors and work areas using a variety of variable equipment features and additional options.
The possible applications of the OverHead Gantry M include measuring, testing and metering applications in addition to machining. The power of the milling motor of up to 2.2 kW and 20,000 rpm and a traverse speed up to 250 mm/sec make it suitable for processing wood and plastic as well as light and non-ferrous metals. The free processing area and its excellent price/performance ratio off er decisive benefits compared to similar products.

The OverHead® Gantry M is available in five different sizes for different process areas from M20 to M50.

Do you require the control cabinet on the right-hand side or would you prefer the control panel to be on the left?

No problem – we will be happy to accommodate your requirements. And of course we will take care of maintenance and support for your OverHead® Gantry M. 

Our service technicians can be reached by telephone and can attend to you quickly on-site as needed. In addition, we also off er our in-house isy-CAM 2.8 software and can advise you on your specific application.

isel safty performance - functional safety

Since October 1st 2019, all isel CNC machines have "yellow safety technology" from PILZ "inside".

We are therefore prepared for all future relevant safety requirements and offer you maximum flexibility and peace of mind for your application.
Behind all this is a SIL and PL certification, which our isel customers can also continue to use for their applications.
We have gained valuable experience for the hardware and software from our numerous special machine projects over the past years, which we are incorporating here as a new standard.

You can also use this added value for your application. In future rely on the "yellow technology" from the market leader PILZ!
