Pedrini Harnesses CoreTigo’s IO-Link Wireless Technology to Enhance the Flexibility and Efficiency of Natural Stone Processing Machines

World-known manufacturer of natural stone processing plants and machines, Pedrini, and the provider of industrial wireless automation solutions, CoreTigo, announce an advancement in natural stone processing machinery. By integrating CoreTigo’s IO-Link Wireless devices into its machinery, Pedrini was able to enhance existing machines, gaining the benefits of this industrial-grade wireless communication, without the need to design new machines.

Pedrini sets a high bar of innovation and digitalization for the industry by constantly growing and developing, taking it into the era of Industry 4.0. Pedrini’s SPECTRA B220 planetary calibrating machine is designed for thickness grinding of natural stone slabs including marble, granite and quartzite. The machine’s calibrating unit is composed of numerous spindles equipped with diamond tools. Optimal performance relies on real-time accurate reading and control of the current of each spindle while in high-speed operational mode. The SPECTRA B220 now utilizes CoreTigo’s IO-Link Wireless communication for monitoring the machine spindles. The wireless solution replaces the need to run communication cables from the spindles through the slip rings of the calibrator and to the PLC.

The deployment’s complexity is reduced significantly with an IO-Link Wireless Bridge (CoreTigo’s TigoBridge) connected to a multiport I/O Hub that communicates current data from 8 spindles simultaneously (and a total of 48 spindles per machine with six TigoBridges). A single IO-Link Wireless Master (CoreTigo’s TigoMaster) collects all the data from the Wireless Bridges on the machine over the air, and communicates it directly to the PLC. The data is visualized on the HMI and enables real-time machine calibration and optimization.

The use of IO-Link Wireless communication allowed Pedrini to switch from complex and high-cost communication slip rings on the calibrators into smaller and more cost-effective slip rings. This new machine design enables a range of benefits and advantages for the SPECTRA B220 machine:

  • Slip ring complexity reduction – cost-effective solution with reduced deployment time and effort
  • Increased flexibility – the wireless solution enables simple retrofit and system expansion by easily adding dozens of connected spindles without slip ring or cabling constraints
  • Improved maintenance – reduced spare parts for expensive slip rings, reduced cable wear and tear, and reduced maintenance operations due to wireless interferences.
  • Reliability – IO-Link Wireless provides performance which is a million times more reliable than conventional wireless systems (such as Wi-Fi or Bluetooth). It coexists with other wireless networks, does not require line of sight, and is designed for high-speed motion applications in harsh industrial environments.

“Implementing CoreTigo’s IO-Link Wireless technology enabled us to further innovate our plants and machines, digitalizing these, and keep marching forward into the Industry 4.0 era, said Michele Romano, Automation Coordinator at Pedrini. This allows us to offer our customers the increasingly higher level of service and ever-evolving work methods they are used to.”

About IO-Link Wireless
IO-Link Wireless is a deterministic, low latency (5 msec) and low synchronization rates (10’s of micro seconds), highly-reliable and scalable universal wireless communication protocol. Based on the IO-Link IEC 61131-9 standard, it is designed specifically for factory automation, coexisting with other networks – both wired and wireless.

About Pedrini
Pedrini manufactures plants and machines for all phases of natural stone processing – from cutting to polishing, from resining to finishing – ensuring precision, reliability and production efficiency. Pedrini is able to quickly respond to customer needs, studying new processing solutions with the utmost respect for the raw material, thanks to a high level of specialization, technical expertise and continuous investments in research and development. That of Pedrini is a dream that takes shape every day thanks to the work, passion and commitment of an entire group of professionals. We want to innovate the natural stone industry with ever-new technological solutions with extreme attention to detail.
