magnetic Milling
Questions and answers
1. What happens in case of power failure ?
Nothing ! The workpiece remains clamped on the magnetic chuck. Indeed, the electropermanent technology of the Turbomill system needs power only for a few milli-seconds to energise and de-energise the system. During the production cycles, there is no power consumption.
2. Is the clamping force big enough to hold large components ?
Yes ! The bigger the workpiece is, the greater is the surface area in contact with the magnetic chuck. The clamping force on the workpiece increases in proportion to its size.
3. Is there any risk of disturbing the function of the machine by using a magnetic system ?
No ! The Turbomill system is engineered and built to have a magnetic circuit in the chuck and in the workpiece. It has no influence on the functions of the machine.
4. The magnetic clamping is invisible ; how can we know if the magnetic chuck is active or not ?
Control units have been designed to enable a visual indication of the chuck condition on the machine PLC or on a separate remote control. A dialog between the chuck control and the machine is installed to ensure a completely safe solution.
5. What happens if the machine operator pushes the off button during a machining cycle?
Nothing ! A dialog is established between the Turbomill chuck and the machine in order to ensure all safety devices and forbids any incorrect operation. A totally secure system is achieved in order to avoid any accidental damage to the machine or to the workpiece.
6. Is the Turbomill chuck waterproof - YES? What happens in case of milling using coolant ?
Nothing !The Turbomill chuck is completely waterproof ! Even in case of infiltration of liquid in the chuck, the design of the Turbomill chucks ensures that there is no risk to the magnetic circuits.
7. Can the magnetic power deform the workpiece ?
This question is relevant and Walker Braillon Magnetics can offer a perfect answer in the form of sliding poles which adjust to the dimensions in thickness or scale on the surface of the workpiece. They secure the deformed workpiece and can guarantee parallelism and flat components.
8. How to machine 5 faces of the workpiece in one set-up, face mill, machine slots, pockets or drill through the workpiece ?
The use of pole extensions or sliding poles allows elevation of the workpieces to expose the 5 faces of the component so that it is suitable for all machining operations in one set up. The machining operations can therefor be carried out, witout damaging the magnetic chucks.
9. Do the chips remain on the workpiece during the machining operation ?
No ! Some chips may stay in cavitites as it is the case without using a magnetic chuck. However, the low depth of the magnetic flux in the workpiece allows the workpiece to be held in total security and optimum clamping. The complete demagnetisation of the Turbomill chucks facilitates the easy removal of chips after machining operations.
10. By fixing the magnetic chuck on the machine, do we loose working area ?
No ! The clamping of the Turbomill chucks on the machine can either be done with clamps or with screws, through the magnetic chuck, without any loss of working area, nor of clamping force. This is one of the many options proposed by Walker Braillon Magnetics. In fact the total working area of the machine table can be utilised.
