Schunk Intec has extended its programme of hydraulic expansion toolholders with Tendo Aviation, which focuses on precision machining applications in the aerospace industry.
Schunk says that safety mechanisms such as anti-pull-out locking mechanisms are partly mandatory in the aerospace sector. With this in mind, Tendo Aviation combines the strengths of hydraulic expansion technology with the benefits of Weldon toolholders. This is said to offer high run-out accuracy, a balancing grade of G 2.5 at 25,000 min-1, good vibration damping and fast tool change using an Allen key. For the use of Weldon shanks, an integrated anti-pull-out locking mechanism ensures orientation of the tools and form-fit clamping.
As a first step, the toolholder is available for HSK-A63 interfaces (8, 10, 12 and 16 mm diameters). Additionally, it is available with an HSK-A100 interface (16, 20 and 25 mm diameters). The clamping diameter can be reduced by using intermediate sleeves.
