Available from Lexair, OML's VariClamp modular clamping system uses a floating mechanism of fixed and moveable jaws and a wide variety of gripper forms to provide custom clamping of irregular-shaped workpieces including round, curved, elliptical, rectangular, stepped and slanted parts. The vises can be configured with a combination of fixed or swiveling jaws, and various styles and heights of grippers – including smooth, serrated, soft, high, and with or without stops. Grippers are added via holes placed throughout the vise to conform to the part shape, and holes are capped and covered when not in use. A swivel mechanism incorporated into the moveable jaw enables clamping of slanted and rough-surfaced parts. The low profiles of the fixed and moveable jaws also enable clamping of thin workpieces for heavy-duty cutting and precision processing.
The vises are available with an optional mechanical clamping force multiplier/limiter that sets the grip force from one to four tons. Operators can set and maintain the grip force to prevent part distortion and establish accurate, repeatable clamp force with a simple, one-handed turn, the company says.
Available in three sizes (100-mm, 130-mm and 160-mm), its wide opening and compact length make it particularly suitable for use with machining centers. An expanding chip cover prevents chips from falling into the lead-screw and inside the vise.

For Idex Health and Science, manufacturing glass components was time-consuming on a VMC. Switching to an HMC with a Cluster Tower vise with DoveLock jaws from Kurt Manufacturing enabled more stable, lights-out machining.
