Title:
DEVICE FOR PROCESSING MATERIALS BY CUTTING
Document Type and Number:
WIPO Patent Application WO/1991/004811
Kind Code:
A1
Abstract:
A device for processing materials by cutting comprises a current source (6) of negative polarity, a unit (13) for providing air flows, a commutating unit (9) and an alternating current source (8). The device further comprises two means (2, 4) for ionization of the air flow with corresponding corona electrodes (3, 5). The means (2,4) for ionization of the air flow are connected to the unit (13) for providing air flows. The corona electrode (3) of the first means (2) is connected to the current source (6) of negative polarity. The corona electrode (5) of the second means (4) is connected to the commutating device (9). The first means (2) is directed towards the cutting zone on the side (B) of the rear surface of the cutting tool (1). The second means (4) is directed towards the chip-forming part (C) of the cutting zone. The device may further comprise a third means (19) for ionization of the air flow directed by its outlet towards the cutting zone on the side (D) of the front surface of the cutting tool (1). The electrode (20) of the means (19) is connected to the current source (21) of negative polarity. The invention makes it possible to intensify the cutting process by ensuring a greater endurance of the cutting tool (1) due to rendering the chip brittle, crushing it and weakening the layer of the material to be cut.
