Workholding: Grip-Fix and Makro-Grip
Workholding for 5-axis milling
Many workholding manufacturers use grip jaws with a gripping tooth contour to clamp workpieces securely. Unfortunately compromises always have to be made when it comes to holding power, accessibility and process safety (reliability). Either your workholding devices ensure high holding power but have a downside in suboptimal accessibility when clamping the workpiece with a huge vice, or your workholding is based on compact and accessible small clamping devices but they lack holding power.
Grip-Fix – Workholding with positive lock technology
The difficulty explained above has been solved by LANG with the patented stamping technology Grip-Fix!
Here a gripping contour is stamped directly in the raw material by an external stamping unit
with a hydraulic pressure of up to 20 tons. Due to the high hydraulic pressure we can completely pass on sharp (spiky) gripping teeth and instead use a gripping contour that looks like small truncated pyramids. With this kind of gripping tooth geometry you obtain substantially higher holding power.
After the stamping procedure which takes about 5 seconds the workpieces are held even at a low locking pressure with best holding power and process safety.
Workpiece clamping is usually realised by Makro-Grip centring vices. Our centring vices are available in different sizes – jaw widths 46, 77 and 125. The Makro-Grip centring vices are equipped with gripping teeth that are the exact counterpart of the gripping contour which was previously stamped in the workpieces.
Thereby a positive lock technology is provided with our workholding.
With LANG workholding you manufacture more cost-efficiently and profitably!
