Advanced toolholders extend tool lives
In comparison to conventional universal toolholders, hydraulic toolholders offer excellent run-out and vibration dampening capabilities, delivering fast tool change and extended tool life.
Schunk said that many customers 'won't believe their eyes' when they hear the price of the new HSK-A63 Tendo E Hydraulic Toolholders Schunk, the specialist in toolholding, workholding and gripping technology, said that the 'E' stands for economic and this new Tendo E with HSK-A 63 interface is a cost effective solution in comparison to conventional universal toolholders

'Collet jaw' chucks offer greater versatility
A 'collet jaw' chuck is more universal than either three-jaw chucks or collets and covers a greater diameter range than conventional collets thus increasing flexibility and cost effectiveness.
Zero-point clamping system reduces work resetting
Universal zero-point clamping system that provides accurate and repeatable set-ups of workholding fixtures allows workpieces to be moved through multiple operations with minimum resetting.
For more than 30 years, Schunk has been the pioneer of hydraulic expansion technology and the new Tendo E is the result of this expertise.
The Tendo E enables the end user to save money with its precision technology that ensures excellent run-out and vibration dampening capabilities.
This in turn, protects the tools and machine spindle from damage.

Quick chuck jaw change system cuts set-up times
Quick-jaw change system, to be shown at MACH 2006, meets the demands of small batch sizes with exceptional accuracy and repeatability, therefore significantly reducing set up costs.
Delivering extended tool life, superior workpiece surfaces and minimum spindle wear are direct results of employing the Tendo E.
The fast and easy tool change with a simple Allen key almost becomes a minor detail - one turn and the Tendo E is ready for use.
For users with frequent tool changes, this simple process helps to save considerable time compared to alternate systems where expensive peripheral units may be required.
* Putting Tendo E to the test - Schunk has compared three totally different systems using a finish milling cutter of 20mm diameter to machine several horizontal paths in a test material (16MnCrS5k).
With a cutting depth of 20mm, contact width 0.6mm and cutting speed of 180m/min speed, the test was stopped as soon as the width VB exceeded the value of 0.3mm.
The tool life travel of a standard ER collet chuck was 230m whilst a heat shrinking toolholder machined 240m.
However, the Tendo Hydraulic Toolholder achieved almost 360m, achieving 56% more than the collet chuck technology and 50% more than the heat shrinking toolholder.
This transfers into enhanced tool life when using the Tendo E system.
For this identical cutting application the number of used tools differs with the collet chuck using 50 tools, the heat shrinking toolholder 48 tools and the hydraulic toolholder 32 tools.
This leads to the conclusion that the Tendo E toolholder reduces the cost of effectively cutting metal.
TENDO E toolholders are available for the interfaces SK 40 + 50, JIS-BT 40 + 50 as well as for the new interface HSK-A 63.
The clamping diameters for SK 50 and BT 50 are standardized at 32mm and the clamping diameters for SK 40, BT 40 and HSK-A 63 are standardized at 20mm.
Smaller shank diameters can be clamped with intermediate sleeves. Request a free brochure from Schunk Intec ...
