FIELD: process engineering.SUBSTANCE: invention relates to tool intended for cutting material arranged on the table. Cutting device comprises table resting on bed to turn in horizontal plane and provided with camping part. Besides, said table incorporates locking bracket to limit turn relative to said bed and coupling part to transmit turn motion in clamping part turn to locking bracket. Clamping part allows changeover between state whereat turn motion in turn of clamping part is transmitted to locking bracket via clutch and that whereat turn motion transmission is locked. In compliance with second version, compression spring is arranged between turn axle and turn control cam arranged at one end relative to turn axle and turn bearing axle and table bottom surface to drive locking bracket downward by the force of said spring.EFFECT: reliable locking, improved control over clamping part.6 cl, 13 dwg |
