Workholding Enables Stress-Relief Reclamping
IMTS 2018: 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 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.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
The challenge holding tight tolerances for its billet RC helicopter engine components drove this company to develop an innovative fifth-axis tombstone device to complete multiple parts on an HMC in one setup.
The maker of racing engine components produces parts that have many permutations within each product line. Here is how Jesel sets up work for cost-effective, responsive machining.
