Studer’s new SmartJet concept supplies a precisely controlled flow of coolant to the grinding wheel, saving costs and increasing sustainability in production.

On many grinding machines it is the operator’s task to manually control the cooling of the grinding process. He or she must position the nozzles correctly and operate the ball valve by hand. A pump then transports the cooling lubricant to the grinding process location. Often, this uses more coolant than necessary or the nozzles lack optimal positioning, which is bad for efficiency and the environment. Studer says it is breaking new ground with its patented SmartJet concept.

From now on, cooling will be the responsibility of the machine control unit. The central components are a frequency-controlled pump and a dynamic pressure measuring unit. This concept makes it possible to set the volume flow precisely to suit the process, whether for roughing, fine grinding or finishing. The coolant flows through a distributor piece and flow-optimised, adjustable nozzles to the grinding wheel.

“Our new concept guarantees precise and reproducible cooling,” emphasises Martin Habegger, project manager. “We create a consistent jet of coolant with a high exit velocity in the range of 12 to 20 m/s, which effortlessly overcomes the air movement caused by the wheel.”

As a result, process reliability improves and less coolant is required to produce equivalent grinding outcomes.

In conclusion, SmartJet not only accelerates set-up time for users, it also enables them to grind significantly more efficiently and sustainably.

“It reduces water consumption by 40% and energy requirements by up to 50%,” states Habegger, before adding: “SmartJet makes a significant contribution to making machining more eco-friendly.”
