Use induction blocks to raise the workpiece above the surface of the magnet and permit machining 5 sides and thru-hole drilling. Individual induction blocks provide maximum flexibility for creating custom setups for holding difficult workpieces and warped stock.
For machining small, thin, or irregular parts that do not have much metal to attract the magnet, you can create a shallow nest, or pocket in a subplate or induction blocks to secure the part and prevent lateral movement. For part nests that you will use over-and-over again on repeat jobs use subplates to save setup time.
Use EEPM-SPF induction blocks on the corners and EEPM-SP spring loaded blocks everywhere else so the induction blocks adjust to match the warped stock.
