WS Series Spring Advance Work Supports
Spring advance work support contacts workpiece as it is loaded into fixture
Low pressure lock-up capability enables the use of machine tool hydraulic systems
High rated support capacities allow for more compact fixture design
Corrosion resistant materials, compatible with most coolants and environments
Threaded and manifold air vent ports allow fixturing that prevents coolants from being drawn into the system
Minimized deflection increases machining accuracy
Multiple mounting configurations for design flexibility
