FAS   Plate

Lots of companies have been using fixture plates for a long time, to make it easier involving quicker sets up and more productive machining. Also known as " Jig-Jack's " This fixture system can eliminate the need to square blocks before doing any machining. Its not for every block, but is very useful for larger blocks, and difficult setups commonly used in a vise where there isn't much to hold onto.

Basic principle ~ Take the raw steel directly to the vise. Face the top of the block ( which is most commonly the bottom of the block ), and profile all the way around the block to the finish dimension. The profile depth would be an optimal depth as to ensure finish clean up from the top. Then do all the hole work necessary. 2 locating holes must be put into the block for holding onto the FAS Plate. These holes are most commonly put on location with the jack screws, or strategically placed not to interfere with any other critical areas of the steel. The special made buttons will then get put into the locating holes. The block is then flipped over, and put onto the FAS Plate and secured with two screws placed through the buttons. The location is determined by how the CAD is drawn. There is a common X,Y,Z Zero on the FAS Plate so that there is no need to pickup any individual blocks. Then all there is to do is finish the profile to dimension which will match what was done on the bottom. Hole work along with any 2D or 3D machining can then be completed.
