OMiL Self-Centering Vises Review: Specs, Price and Applications
OMiL self-centering vises are centric clamping force blocks in pneumatic-hydraulic and manual versions, supplied by Essential Robot Products.
The powered versions have hardened steel functional parts, a wedge with key for rigidity, integrated pressurization and central lubrication, and come pneumatic, hydraulic (120 bar, higher on request), pneumatic spring-loaded or with one fixed jaw. Manual versions use a nitrided 42 NCD4-V steel screw, hardened body and jaws, and offer 0.01 mm repeatability.
Quick Verdict
Rigid, precise centric vises that make robot-loaded machining fixtures repeatable and automation-friendly.

Design and Operating Principle
Centric vises close both jaws toward the centre, so parts of different widths are always located on the same axis, which is ideal for robot loading.
Wedge-and-key construction provides rigidity under machining forces, and central lubrication extends life in automated duty.
Spring-loaded pneumatic versions hold clamping force without air, a safety benefit if supply is interrupted.
Integration and Selection
Choose powered versions for automated cells and manual for setup fixtures. Interlock clamp status with the robot.
Machine soft jaws for each part family.
