Description: |
| Claim:
The present invention relates to a box turning tool, particularly for automatic screw machine, and has for an object to provide a tool of this character in which a plurality of cutting tools may be supported in relation to work supporting rests, so that a plurality of diameters may be turned simultaneously upon the work. It is especially proposed to provide a box turning tool in which the tool holders and work rests may be accurately adjusted, both as to the diameter of the work and the longitudinal spacing of the different diameter cuts, and which will positively retain such adjustment, so that when once adjusted the only variation in the diameters will be that caused by normal wear of the cutter bits. |
