GEHRING TECHNOLOGIES introduced the next generation of its control system, GHC 3.0 — a direct successor to the GHC 2.3 that ensures long-term availability but also delivers a substantial technological leap.
The first implementation of GHC 3.0 is currently underway at an international pump manufacturer in Germany, on two machines scheduled for commissioning. In this high-end retrofit project, GHC 3.0 not only handles classic NC control but also manages the entire honing process, from tool set-up and feed control to process-specific parameterization.
Unlike machine builders who rely on third-party standard controls, Gehring consistently develops its own fully integrated solution. The complete machine logic—including NC axis control, process parameterization, and tool management—is handled directly within the Gehring Hone Control (GHC). Unlike vendor-neutral systems, Gehring integrates full process intelligence, which results in precise control of tool motion, stroke lengths, feed parameters, and measurement cycles.
GHC’s open structure allows for seamless adaptation to specific customer requirements, a level of flexibility that standard systems rarely offer.
Familiar user interfaces are largely retained, simplifying upgrades and migration. Thanks to its high degree of integration, retrofitting with GHC 3.0 is far less complex and more secure than with external control logic.
“GHC 3.0 is our response to growing technical, economic, and service demands,” said Gunther Dreizler, retrofit sales manager at Gehring Technologies.
At the heart of this upgrade lies the Gehring Control Unit (GCU 3.0). In the past, each spindle, stroke axis, or measurement function required its own control unit. Now, with the GCU 3.0, up to six spindle units can be controlled simultaneously, reducing hardware requirements and installation time while boosting system stability. Communication is managed via high-performance bus systems such as EtherCAT, ensuring short cycle times, low latency, and robust functionality.
Spare parts for GHC 2.3 are becoming increasingly scarce. At the same time, fewer service tech-nicians are familiar with the older systems. The full process logic of GHC 3.0 continues to be developed and maintained in Germany. “Those who migrate now reduce risk, lower maintenance costs, and take their machines to the next technological level,” Dreizler said.
Gehring provides end-to-end support throughout the migration process, from in-depth analysis and tailored project planning to efficient implementation, and customized to fit existing machines and production environments.
