The chip collection unit 8 includes a chip guiding member 81 provided on one lateral side of a chip falling area R1 that is located downwardly of the lower communication hole 20b, and a first air discharge unit 82 provided on another lateral side of the chip falling area R1. The chip guiding member 81 includes at one end thereof a chip collection port 81b located corresponding to the chip falling area R1, and is connected at another end thereof to a chip collector 83 capable of collecting the chips M1. The first air discharge unit 82 includes an air nozzle 82a configured to discharge compressed air towards the chip collection port 81b.

Abstract: A tip dressing cutter (1) includes a rotary holder (5) and a cutter plate (2). The cutter plate (2) includes a cutting blade portion (2d) formed on a continuous portion of a rake face (2a) and a flank face (2b) and extending along a direction intersecting with a rotation axis (C1). A plurality of recessed grooves (2e) are formed on the flank face (2b), the plurality of recessed grooves (2e) extending from a location proximate to the cutting blade portion (2d) in a circumferential direction around the rotation axis C1 away from the cutting blade portion (2d) and being spaced at predetermined intervals along a direction intersecting with the rotation axis (C1).

Abstract: A tip shaping apparatus presses electrode tips against a shaping roller thereof held by a rotationally driven holder in such a manner as to bring tip sections of the tips close to each other, thereby shaping the tip sections into reusable condition. The tip shaping apparatus includes deburring sections located in such positions as to confront burrs that are formed during shaping in such a manner as to project from outer circumferences of root sections proximate the tip sections of the electrode tips in a direction perpendicular to the axes of the electrode tips, at ejection of the electrode tips from the apparatus. Each of the deburring sections is located proximate an outer circumferential plane of the root section of each of the electrode tips undergoing shaping so as to abut against and cut off or bend the burrs in such a manner as to suppress the projecting height of the burrs when the electrode tips are ejected from the tip shaping apparatus.
