The STH-Series provides the most advanced technology available to make jobs easier and more productive. A PLC control and digital display allow complete control and monitoring of machine conditions. A stroking servo motor allows speeds to be changed during operation with minimal dwell time for stoke reversals.
Stroke speed is set through a numerical keypad to assure accurate speeds in both directions.
A built-in load meter indicates high and low spots in the tube bore so the operator can adjust the stroke as required for optimum cycle time. The operator can also work out tight spots in the bore when using the Short Stroke Cycle and Stroke Dwell features. The Sunnen Modular Honing Tool System continually compensates for stock removal and stone wear to keep the machine running at peak efficiency at all times. Several different tooling systems are available depending on the specific application.
