Carr Lock® Subplates are precision-machined steel plates with Carr Lock® Receiver Bushings installed in a standard pattern. These subplates serve as the foundation of an efficient quick-change fixturing system. Subplates should generally be large enough to cover most of the machine table, for maximum fixture flexibility, but should never extend beyond the machine table. For maximum quick-change benefits, subplates are usually left permanently on the machine table while only the mounted fixtures or vises are exchanged. Made in the USA.
The 14 x 26 subplate shown here has (12) 20mm Face-Mount Receiver Bushings for mounting any of the following:
(2) 12 x 14 Carr Lock® Fixture Plates
(1) 14 x 14 Carr Lock® Fixture Plate
This subplate is also available as part of a Carr Lock® System Kit (see Related Products below).
Subplate with (2) 12 x 14 Fixture Plates (System Kit CL-1426-00-CLSK)
Subplate with (1) 14 x 14 Fixture Plate
The Carr Lock® System is extremely accurate. All Receiver-Bushing installation holes are located +/-.0002" from their primary reference hole. Clamping repeatability is +/-.0005", while bushing concentricity is .0002" TIR. The resulting x/y-axis repeatability of a mounted fixture plate is +/-.0028" considering all tolerance accumulation.
Two locating holes for Sure-Lock™ Fixture Keys are provided for alignment with a slotted machine table. Fasten to the machine using the six mounting slots, with Socket-Head Cap Screws and T Nuts to match the machine table.
Design Considerations and Safety Precautions
Never use a subplate that extends beyond the machine table on which it is mounted.
