Makro•Grip® 77, 5-Axis Vise-德国LANG模块化夹具_零点定位系统_精密虎钳

Key data at a glance

The shortest version of the 5-axis vises with jaw width of 77 mm is suitable for smaller workpieces. By reversing the jaws, the vise achieves a maximum clamping range of 85 mm with a base body length of 102 mm. As with all Makro•Grip® 5-Axis Vises, workpieces are clamped centrically at a clamping depth of only 3 mm in the serration. Due to the defined, repeatable positioning of the component in the serration, no additional workpiece endstops are required. Thanks to its compact design and the low interference contours, the 5-Axis Vise is predestined for 5-sided machining.

Makro•Grip® Stamping Technology and Raw Part Clamping

The Makro•Grip® 5-Axis Vise and its unique benefits of the stamping technology has been considered „The Original“ and a benchmark in the 5-face machining of raw parts for years. Its compact design and high holding forces make the Makro•Grip® 5-Axis Vise the ideal clamping device for machining raw parts.

Holding force Thanks to the form-fit clamping principle, highest holding forces can be achieved with Makro•Grip®, even at low clamping pressure.
Process reliability Clamping with Makro•Grip® provides maximum process reliability and is easy on the workpiece to be processes at the same time.
Accessibility The compact Makro•Grip® self-centering vises guarantee ideal accessibility in the 5-axis machining of raw parts.

Tungsten-Carbide-Coating

A special Tungsten-Carbide Coating can be applied on the plain clamping surfaces of the Mak-ro•Grip® jaws in order to double the friction force when clamping non-stamped parts, without leaving any traces on the workpiece.

Modified Clamping depth

Sometimes raw material has a certain radius, which makes it hard to clamp it on the 3 mm step of the Makro•Grip® jaws. This can be solved by lowering the clamping step so that the workpie-ce is held above the radius. On the one hand, this provides a resting surface for the workpice, on the other hand it ensures safe clamping.

Modification of Base

The case-hardened base body of all LANG vice types allows additional threaded holes or fittings to be inserted on the bottom in order to be able to use the vice on other zero-point clamping systems or to mount it to any fixture.
