Abstract

This is a system for feeding boring machine cutting tools toward a greater or lesser cutting radius. Any change in radius under present conditions requires stopping the spindle. With this system, full control is had by a programmer without stopping the spindle.

Automatic Facing and Grooving System

This is a system for feeding boring machine cutting tools toward a greater or lesser cutting radius. Any change in radius under present conditions requires stopping the spindle. With this system, full control is had by a programmer without stopping the spindle.

The tool head 10 has a tool holder slide 11 that is adjustable along the diameter of the spindle by lead screw 12. Secured on the lead screw is a gear 14 that is part of a train 15 and 16. Gear 16 is secured to shaft 17 journalled in a hollow bushing secured to a tool changer ring 18. Secured to the other end of 17 is a star wheel 20. Located one above the other and in alignment with 20 are two pins 21 and 22 which are the armatures of two solenoids 23 and 24. These are mounted in a bracket 25 secured to the frame of the machine in such a manner as to be free for up and down movement under control of the springs 26 and 27 connecting yokes 28 and 30.

The upper pin 21, when injected into the path of the star wheel 20 by solenoid 23, causes rotation of the wheel one step for each revolution of the tool head to feed the cutting tool toward a larger radius. With pin 22 injected into the orbit of the wheel the cutting tool is retracted. As the star wheel passes over or under an injected pin, the solenoid is displaced to extend the springs 27. This actuates a counting switch 31 through the arm 32 that cooperates with the coil of the solenoid. Should the tool slide reach a limi...
