Claims

[Scope of utility model registration request]

A main shaft 3 rotatable by a power source 13 at a fixed position in a case 2, and a groove 30 that rotates together with the main shaft and is slidable in the direction of its rotational axis 23 and has a sloped surface 31 inclined with respect to the rotational axis. guided by a leaning moving shaft 4 and a guiding cylindrical portion 10 bridged on the main shaft 3 in a direction perpendicular to the rotational axis 23;
One end of the groove 30 fits into the groove 30, and a sloped surface 42 formed at the one end and both side surfaces of the groove 30 fit into the groove 30.
a tool mount 5 that is slidable on the inner surface of the 0;
The cutting tool mount 5 is biased in one direction of movement by a spring 60 so that its sloped surface 42 aligns with the sloped surface 31 of the moving shaft 4.
A cutting tool feeding device 1 for a machine tool, characterized in that the moving shaft 4 is constantly in contact with the feed screw 6, and the moving shaft 4 is pressed against the feed screw 6 due to this contact.
