Outside a slim heat shrinking contour, inside a clever hydraulic expansion technology is how the exhibitors from Schunk describe their innovation. The slim precision mounting makes it ideal for use in series production, particularly in the automotive industry, as the German company insists. The tool-holder has been particularly designed for axial operations, and reportedly demonstrates its special merits during milling close to interfering contours, countersinking, reaming and thread milling in 5-axis centers, prototype construction, and operations in the die and mold industry. According to the manufacturers, test series have shown that the mountings with the vibration-damping properties of the hydraulic expansion technology have considerably improved the milling process. The hydraulic expansion tool-holder design is said to reduce the peak cutting amplitude of the force progression in the X-/Y-direction, which results in less deflection of the tool. By reducing the load of the cross cutter and the cutting edge, considerably longer service life can apparently be achieved. In addition, the user also benefits from having exact gauges for holes and maximum precision at the workpiece.
Slim heat-shrinking contour plus hydraulic expansion technology
The Schunk Tendo Slim 4ax hydraulic expansion tool-holder reportedly combines for the first time the complete outside geometry of heat shrinking mountings according to DIN 69882-8 with the proven qualities of the company's hydraulic expansion technology.
