Stamping Technology: What is pre-stamping?
Through pre-stamping a workpiece is indented with a defined contour with a stamping power of up to 20 tons of hydraulic pressure before it is clamped in the clamping fixture with form-closure, offline or outside of the machine tool. Thanks to pre-stamping workpieces can be clamped in compact clamping fixtures and with relatively low actuation forces, but with high holding power and great process reliability. The whole pre-stamping process only takes max. 5 seconds.
When does pre-stamping workpieces makes sense?
Pre-Stamping compared to conventional vices with gripping jaws
Clamping with only 2 tons of pressure is also the reason why the LANG 5-axis vice is constructed lightweight and compact and offers perfect accessibility for 5-axis machining. With pre-stamping as a factor even raw material with a tensile strength of 1500 N/mm² can be stamped and clamped securely. The clamping requirement of the workpiece is less than 3.5mm and leads to lower material removal on the finishing side.
These are only a few reasons why pre-stamping is unique. See for yourself and experience the benefits of pre-stamping. You will be impressed!
