PCT No. PCT/SE96/01273 Sec. 371 Date Jul. 14, 1998 Sec. 102(e) Date Jul. 14, 1998 PCT Filed Oct. 9, 1996 PCT Pub. No. WO97/13626 PCT Pub. Date Apr. 17, 1997Method of machining a thermosetting laminate (13) by means of an apparatus comprising at least one high-frequency or ultrasonic oscillation generator (1) and at least one dimension changing or adjusting unit (4) having at least one piezoelectric crystal (8) performing a linear vibration when charged with an alternating current. The linear vibration is propagated through at least one mechanical or electronic amplitude transforming unit (5), whereby generated high-frequency or ultra-sound amplitude is transformed into a linear vibration. The linear vibration is during machining propagated via at least one tiller or tool holder (7), being connected to the amplitude changing unit (5), to at least one tool (2) attached to the tiller or tool holder (7) and consisting of a least one diamond (3), whereby at least said tool (2) performs a linear vibrating movement (16) and whereby said tool (2) executes said machining. |
