Coning and threading machine for high-pressure tubing

A machine for coning and threading an end of a length of high-pressure tubing, each length of tubing having a primary longitudinal axis corresponding with its center and running throughout its length, said machine comprising:

• a) a collet for receiving a first end of the length of the high-pressure tubing and holding the primary longitudinal axis of each length of tubing aligned with and centered on a first axis of said collet;
• b) a carriage mounted upon a frame for both longitudinal and lateral movement, said carriage mounting
• i) a coning head for forming a taper on the first end of the tubing;
• ii) a threading head for creating a thread length on the taper formed by said coning head on the first end;
• c) a translation handle for positioning said carriage in one of three locations:
• i) a first central location where said collet is loaded;
• ii) a second location spaced laterally from said first central location in a first direction, in which second location said coning head is aligned with the primary axis of the length of tubing being held in said collet;
• iii) a third location spaced laterally from said first central location in a second opposite direction from said second location, in which third location said threading head is aligned with the primary axis of the length of tubing being held in said collet;
• whereby the first end of the tubing can be tapered by said coning head, and threaded by said threading head while engaged in said collet without the need to be repositioned in said collet.
