Stamping technology and makro grip vice from Kitagawa
In contrast to traditional machining vices, which simultaneously "pre-stamp" and clamp a workpiece with a maximum of 4-6 tons, Form-Closure Technology with external stamping from Kitagawa adds the form-closure contour indents to the workpiece with up to 20 tons of hydraulic pressure.
This allows you to clamp even high-tensile materials up to 1500 N/mm2 tensile strength (e.g. Titanium and Inconel) within 3-5 seconds reliably and virtually wear-free.
No need to dovetail parts prior to machining process. Pre stamping directly conducted on saw cut or rough layer of workpiece
Stamping depth is reached when the control marks between indents have reached a max. depth of 0.1mm.
Form-closure technology allows handling of large work-pieces even with compact vises at only 3mm clamping depth.
Form-Closure Technology makes LANG Clamping the very best in 5-axis machining, guaranteeing maximum holding power with minimal clamping force.
