Automatización modular de CNC y robots con una plataforma común

“Our CNC precision tool grinders need to meet a number of important criteria,” states Hartmut Rühl, Head of Software Development at SCHNEEBERGER. “Firstly, they must process hard cutting-tool materials such as carbide, HSS [high-speed steel] and ceramics. Our machines must also achieve ultra-high precision, in the micron range, while another prerequisite is ensuring optimal surface quality.”

Around 30 years ago, SCHNEEBERGER began searching for an industrial control that was highly flexible, precise and dynamic, and able to interpolate at least five axes simultaneously. For communication with the operator, a user-friendly interface was also essential. 

The solution supplied to SCHNEEBERGER today is based on a FANUC 31𝑖-B CNC with FANUC PANEL 𝑖H Pro industrial PC. Thanks to the use of FANUC I/O Link𝑖, the CNC and FANUC robots communicate via a single control platform. 

“For us, connection between the robot and CNC is a great advantage,” declares Antonio Grasso, Head of Electronic Development at SCHNEEBERGER. “It means that our users can monitor two completely different systems with one control. What’s more, our adoption of the latest 31-𝑖B control means we now have a CNC with even better diagnostics capabilities, thus enhancing machine reliability.”

As another benefit, SCHNEEBERGER has been using FANUC linear and torque motors since the beginning of 2000. These motors help deliver the short, fast oscillating motion of SCHNEEBERGER machines as part of the tool-grinding process. According to Grasso, “this has brought a clear improvement in grinding quality and tool precision”.

Today, SCHNEEBERGER is a near-exclusive user of FANUC products: robots, CNCs and motors.

“FANUC has proven to be a very reliable and competent partner for us over the years,” concludes Rühl.
