Slim hydraulic extension will interest mould and die makers

A long, slim hydraulic expansion extension from Schunk Intec dispenses with the need for auxiliary equipment and can transform almost any precision toolholder into a versatile tool for narrow spaces, independent of the spindle interface.

Of particular interest to the tool and die industry, minimal run-out, excellent vibration dampening and internal coolant supply ensure outstanding machining results and long tool service life. The high-precision, fine-balanced Tendo extension allows fast tool change via an Allen key that is operated radially from the side. This makes tool changing particularly convenient, and means that tools can be changed even when in the machine. The high torque of the hydraulically clamped extension ensures that tools are held securely for all boring, reaming and finish milling operations. A single Tendo extension can be fitted with a variety of standard tools, dispensing with the need for expensive specialist tools. The extensions are available in six different standard sizes with a shank diameter of 20 (L1 is 150 mm) or 32 mm (L1 is 150 mm or 200 mm) with clamping diameters of 12 or 20 mm.
