Abstract
A carriage 3 is movable in a feed direction A on guideways 1, and carries an ultrasonic machining device 4, 5 loaded with an adjustable force in the feed direction by a first fluid cylinder 7. A cylinder 15 is attached to the carriage, around which is looped 16 a rope 17. One end 18 of the rope is preloaded by spring 20 against a stop 21 which is attached to a frame 2. The other end 22 of the rope is attached to the piston rod 24 of a second cylinder 25. By means of the second cylinder the tool 5 can be lifted or retracted from the workpiece 6 during the machining operation, independently of the position of the carriage. After the tool has been lifted off, the tool touches down gently again on a renewed abrasive layer.
