Trimming jigs is essentially a tool that helps to accurately repeat the same action over and over again. By holding a workpiece at several points or allowing work-pieces to clamp together, jigs allow users to drill holes, remove material precisely.
Trimming jigs are used in uni-dimensional machining processes like drilling, tapping, and reaming.
Trimming jigs are indispensable in the machining process. They help guide and hold workpieces to a specified location, thus ensuring that any drilling or tapping will be accurate. These devices can also have clamps on them for holding objects firmly during reaming.
