A set of mechanical bases placed on the machine table, ensuring repeatability of the arrangement of the given material (usually boards). The operator, when placing the material on the table, pushes it against the protruding pins, thanks to which it is placed in the right place. This solution helps with large-scale production of elements.
Options available:
Manual pins - the operator places them in special sockets, and after placing the material, he manually removes them for the time of processing
Automatic pins - the pins automatically slide out of the table and retract after machining to avoid a collision with the tool.
