DB1430 Tread Cutting Device
The DB1430 Thread Cutting Jig allows threads to be cut on a workpiece which is held in a chuck mounted on the special spindle of the jig, which advances 2 mm with each full revolution (i.e. the spindle acts as a 2 mm pitch leadscrew). A cutter with a 60 degree included angle and 8 mm shank is held in a small chuck mounted in the lathe's main spindle and is used to create the thread form in the workpiece. The system adjusts to the workpiece diameter and the depth of thread is varied by indexing the compound table across the lathe bed.
