The invention belongs to the technical field of cutting devices, and particularly relates to a cutting device with a leftover material collecting function for production of mechanical equipment. Aiming at the problems that a device is low in shockproof coefficient, leftover materials are not collected, a cutting knife working for a long time is not cooled either, meanwhile, the cutting angle of the device is fixed, and practicability is relatively low, the following scheme is proposed, specifically, the cutting device comprises a base, supporting blocks are fixed to the outer walls of the fourcorners of the bottom of the base through bolts correspondingly, and shockproof pads are fixed to the outer walls of the bottoms of the four supporting blocks through screws correspondingly; and first sliding grooves are formed in the outer walls of the two sides of the top of the base correspondingly, sliding rails are fixed to the inner walls of the two first sliding grooves through bolts correspondingly, and the inner walls of the two sliding rails are slidably connected with first sliding blocks. According to the cutting device, the shockproof coefficient of the cutting device can be increased, the stability of the cutting device is also improved, the cutting requirements of different mechanical equipment are met, thus the cutting device is more practical, and the cutting quality andefficiency are improved advantageously.
