Traditional mechanical workholding systems cause deformations: RadialTec offers an innovative solution for machining rings using a single support surface through mobile extensions.
Uniform magnetic workholding, no deformation or vibration of the workpiece on the 3 faces for grinding and turning operations after hardening. Better finishing quality, longer tool life.
The solution
RadialTec, permanent-electro magnetic systems for turning and vertical grinding
For every company involved in the turning of washers, bearings, rings and flanges, a common problem is holding the workpiece without deforming it. In fact, traditional mechanical workholding systems cause ovality and deformations. RadialTec clamps the workpiece from the support surface only. There are no obstacles to the tool path: a complete machining of the workpiece is possible with a single positioning.
The use of pole extensions allows the workpiece to be spaced from the surface of the chuck, making the internal and external diameters completely accessible for any machining. The uniformity of workholding typical of the magnetic system eliminates problems due to vibrations, with great benefits in terms of machining tolerances, tool life, chip removal and machine productivity.
The new PRF series with mono-block technology is equipped with an entirely metallic surface; this guarantees a high level of robustness and perfect insulation of the components placed within the system.
Compared to alternative solutions with a trapezoidal pole, the rectangular shape of the pole offers consistent performance along the entire radius (therefore on workpieces of any diameter) and constant depth of the magnetic flux.
Advantages
AUTOMATIC SHIMMING AND STRESS REDUCTION
The combination of movable and fixed pole extensions forms a flexible bed that adapts the magnetic surface to the workpiece, compensating for its irregularities, without the need for shimming. Stress reduction operations are carried out quickly and automatically.
FULL USE IN THE MACHINE TABLE
RadialTec does not require spaces to be allocated to clamps or other workholding units, allowing full use of the machine table, able to be installed with a diameter equal to or even slightly larger than the original one.
CONCENTRATED FORCE IN THE ABSENCE OF MAGNETIC RESIDUE
The Neutral Crown configuration allows the magnetic flux to be fully concentrated on the active surface, guaranteeing maximum efficiency and total isolation of the module.
“PRF” models are equipped with a control unit that has a special demagnetization cycle (Nuflux system) to completely remove the magnetic field from the workpiece during the DEMAG phase.
“FULL METAL” STRUCTURE
RadialTec chucks are obtained from a single piece to increase their rigidity, precision, structural stability and reliability over time.
The work surface is entirely metallic and therefore free of epoxy resin or any junction element that could compromise its performance or allow infiltration of the coolant due to vibrations and overheating generated during machining phases.
