CRS39 Bolt Thread Cutting Machine is used for turning pipe thread, metric thread with different blades for different needs. It has strong applicability and can be used for pipe material and bar material. Applied into mass production of steel pipe factory, mining bureau, building, bridge and other related enterprises.

Its characteristic is: when processing the cutting operation, the work is to be held in a vice on the work saddle and fed, through turning of the hand wheel, to the rotating die head until it is gripped by the chasers automatically for cutting the thread. The axis of the work is aligned with that of the die head so that the thread cut is accurate and smooth.

Its feature is: a control rod with trip dogs is installed to enable the tangential chasers to be opened automatically at the end of the preset threading stroke, and the spindle speeds can be easily adjusted due to a wide range of speed changes selections.
