All Rectangular Tooling Plates can be mounted as quick-change fixture plates on a subplate, as well as directly on a T-slotted machine table. Instead of the Locating Keys and Sure-Lock Fixture Keys used above for two-axis location, Subplate Locating Keys are used for three-axis location. A round key and a diamond (relieved) key are used together for precise location without binding. The subplate hole pattern shown here allows mounting any size and combination of standard or heavy Rectangular Tooling Plates, either lengthwise or widthwise.
