(1) Magnetic Way Installation
The SGLFM magnetic way is packed with a cardboard sheet covering the magnetic
surface, above which is a thin, rectangular steel plate.
The steel plate is a dummy plate used to reduce the influence of magnetic force on the
surrounding environment. When removing the plate, make sure that fingers are kept
clear and that the magnet and magnet protection cover are not damaged.
Use the following procedure to install the SGLFM magnetic way.
1.
Remove the dummy plate used to reduce magnetic force and the
cardboard sheet from the magnetic way’s magnetic surface.
2.
Align the reference marks (approx. 4-mm dia. indentations) on the side
of the magnetic way with the reference surface of the machine base,
keeping fingers clear to prevent injury.
3.
While placing the magnetic way on the machine base reference surface,
secure it with bolts.
Note: Use hexagonal socket head bolts (tensile strength Class 10.9).
