ASTM A36, 1/4" - 8" thick
AISI 4140, tool & die steel

Custom CNC Machine work holding clamps. Special Shape holders and clamps - custom cut and ground to order.

These custom designed workholding clamps, shaped like tuning forks, hold and support (2) 5" x 14.5" x 240.5" side frame plates onto one of our t-slotted bar mills. The t-slotted bar mill, machine table is 72" x 144". These top plates rotate 90 to the vertical  plane so that we can drill holes in either the x-, y-, or z-plane, dependant upon "in which orientation" the plates lie upon the mill. When completed, these 4340 quenched and tempered plates will have recessed through holes inside oblong shaped slots on the faces, and both ends and edges are to receive drilled and tapped holes of various diameters and depths.
