Workholding Enables Stress-Relief Reclamping

The Schunk Vero-S Aviation product line is designed to rigidly clamp large parts accurately and enable the user to release the part enough to allow the part to move (compensate) due to the stresses of machining without fully releasing the part. The clamp/unclamp and reclamping of the stress-relieved part can be done in under a minute without losing the established primary reference datums, according to the company. This is accomplished through the use of four modules: the first module is fixed in all axes to establish the primary reference point; the second module allows the workpiece to compensate in one axis (X axis); the third module allows the workpiece to compensate in two axes (X and Y); and the fourth module allows compensation in all axes including height and angularity.
