For short production runs, adjustable fixtures can be quite beneficial. However, to be most effective , they do require that the products to which they are applied are of a type. They are most effective when dealing with various sizes of a similar object. For example rectangular circuit boards, or enclosures of various sizes.
Linear rail adjustable fixtures are excellent choices for short production runs of rectangular circuit boards or other thin, flat, and rectangular products. Usually they are set up to have a fixed bottom left corner, a back adjustable rail, and then stops to constrain left and right motion. Optional steel scales on all four sides makes resetting the fixture back to pre-existing pattern programs a simple task.
Grid fixtures represent the most flexible alternative in the pantheon of fixtures. Our grid fixtures are an array of 8-32 tapped holes on one inch centers. Each grid fixture comes with a kit of standoffs and a set of parallel rails that are slotted for maximum flexibility. The pitfall of this type of fixture is that it is difficult to change the fixture back to a pre-existing configuration once it has been changed. Conversely, the grid fixture is relatively inexpensive because they are made in quantity, all fixtures have machine bushings for mounting, and it now becomes reasonable to have multiples of these to deal with odd components. When an application is known to be at an end, it becomes reasonable to strip the adjustable fixture and put it to use for the next unique application that comes along.
