Shrink-Fit System Offers OneTouch Displays, Rapid Tool Cooling

The Diebold/Accutek US1100 Series of shrink-fit machines combine Accutek’s shrink-fit technology with the Diebold brand of shrink-fit machines and feature the latest OneTouch display and Pyrometer Coil technology.

The OneTouch Display is an operating mode that works in conjunction with the machine’s TempControl (Pyrometer Control) safety function. This feature is designed to eliminate operator errors and the overheating of shrink holders. Also, it means that no selection of parameters are required. Users can set the shrink process with just one touch. The system provides a graphical visualization of shrinking process and hands-free operation with an optional foot pedal. It is also IoT 4.0 ready with Ethernet and data exchange.

The US1100 shrink-fit machines are available with the Pyrometer Coil technology included as standard. The technology is automated with direct temperature monitoring for reliable and stable tool shrinking. The Pyrometer technology (with TempControl sensors in the coil) measures the surface temperature of the holder during the shrinking process and controls the process. The maximum programmed temperature is controlled and, once it is reached, the bore is kept open for a longer period of time to enable tool changes. It is said this feature virtually eliminates the possibilty of overheating the toolholder during the shrinking process.

The US1100 TubeChiller machine offers a fully automatic solution for automated shrinking and a subsequent cooling process. The TubeChiller technology was developed to combine the shrinking devices of the US1100 series with automated cooling. Once the shrinking process is completed, the cooling take place automatically, without the risk for the operator having any contact with hot tools. After the shrink process, the cooling tube lifts up from the TubeChiller housing and pushes the coil out of the way. During this period, the TubeChiller is filled with coolant as it rises and flows around the toolholder. The coolant is agitated with air to help maintain a uniform coolant temperature because heat dissipates through the air bubbles. After the cooling process, the TubeChiller recedes back into the housing as it air dries the holder with blasts of air. In less than 2 minutes of total cycle time, users go from worn tool to new tool and ready to put the holder back into the CNC machine spindle.
