Vises and Vise Jaws

Reinventing the Unbreakable Grip

Examine the design of these machine tool vise jaws to understand how they enable aggressive 5-axis machining of high-value medical and aerospace parts in a single setup by clamping on as little as 2 mm of surface.

Stacked Hydraulic Workholding Beams Up New Business

ProHold hydraulic vises such as this can clamp a wide range of parts with same tooling and have a longer hydraulic stroke that allows several different sized parts to be processed with the same top jaws. This significantly reduces set up time and effort for quicker loading.
Special Machined Components took beam machining business away from a competitor by using a ProHold six-vise stacked hydraulic workholding system from Planet Products.

Clamping for Difficult Machining Applications

The non-rotating air manifold in the Systec chuck uses Teflon seals that are virtually maintenance free and help increase the grip force. The chuck operates with just 90 psi air pressure. Internal safety valves prevent loss of air pressure and gripping force.
These clamping systems from Lexair are ideal upgrades for manual lathes, rotary tables and indexers that require higher grip force for difficult applications.

Smart Workholding for Precision 5-Axis Milling

The vise maximizes clamp force at the top of the jaws by pulling them closed at the top with a collapsing lead screw while holding the bottom of the jaws in place with an opposing force screw. This eliminates the tendency of traditional vise jaws to splay apart at the top and require machine operators to hammer the workpiece down against the stops as the jaws close and clamp force increases.
Ideal for production machining, the OML Genius 5-axis vise from Lexair pulls jaws together at the top to clamp down the workpiece with a 9,000 lb force that eliminates issues faced with traditional vise jaws.

Powerful Vise Clamping System for 5-Axis Machining

The KontecKSX NC vise is ideal for simultaneous 5-axis machining because it fits smoothly into the Schunkmodular system for highly efficient workpiece clamping. This means the clamping pins of the VERO-S quick-change pallet system can be directly integrated into the base body of the 5-axis clamping vise. 
The Kontec KSX NC vise from Schunk USA provides a safe and secure hold, even for minimum clamping surfaces, between 0 to 250 mm. By using draw bar and base body extensions, the clamping range can be enlarged to 749 mm.
