These precision Riser Blocks provide an economical way to raise an MC60, MC60Z, or SCS80 vise for 5-Axis machining. The 4 x 4 x 7 block shown here is furnished with locating and mounting holes on top for a 5-axis vise, and with bottom locating holes for accurately mounting on a modular fixture plate. This size can also be mounted directly on a rotary table. Made in the USA.
To locate the Riser Block at the exact center of a rotary table, first install a Center Locating Key that matches the table's center-hole diameter in the riser's 25mm bottom center hole. For exact radial orientation, install a Step Fixture Key that matches the table's slot width in the riser's 20mm bottom slot. Fasten the riser to the machine table with two 1/2-13 x 1.25 or M12 x 30mm socket-head cap screws and T Nuts to match the table slots.
