The slim precision mounting makes it ideal for use in series production, particularly in the automotive industry.
It has been designed for axial operations, and shows its advantages during milling close to interfering contours, countersinking, and reaming in 5-axis centres and the die and mould industry. Test series prove that the mountings with the vibration damping properties of the hydraulic expansion technology have considerably improved the process during milling operation.
The hydraulic expansion toolholder design reduces peak cutting amplitude of the force progression in the 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 be achieved. Additionally, the user benefits from having exact gauges for holes and maximum precision at the workpiece.
As with every Tendo hydraulic expansion toolholder, the Slim 4ax also has permanently high runout accuracies, good vibration damping and a fast tool change with a wrench. Even narrow shape and position tolerances can be met precisely, therefore investments in high priced peripheral devices are not required.
Since the precision mounting can replace conventional heat shrinking toolholders by the ‘Plug & Work’ system without having to reprogram the machine, the benefits can be tested in a real application. This means the Schunk Tendo Slim 4ax can be used without expensive peripheral devices.
The MQL-capable mounting is dirt-resistant and is low maintenance. In contrast to the heat shrinking toolholders, it has a permanently high runout accuracy of < 0,003mm at an unclamped length of 2.5 X D and a balance grade of G 2.5 at 25,000rpm.
The Schunk Tendo Slim 4ax fits seamlessly into the proven hydraulic expansion toolholder program from the company. In the first step, the mountings are available for the interfaces HSK-A63 with 10mm diameter/L1=120mm, 12mm diameter/L1=90mm diameter, 12mm diameter/L1=120mm, 14mm diameter/L1=90mm, 14mm diameter/L1=120 mm, and 20mm diameter/L1=90 mm.
Further variants with 6mm diameter to 32mm and L1-dimension of 90mm, 120mm, and 160mm are planned.
