The invention discloses a
cutting and
grinding device convenient to use. The
cutting and
grinding device convenient to use comprises a shell, wherein a first separation chamber, a second separation chamber and a separation plate are arranged in the shell; a reciprocating support, racks, a half tooth gear, a first motor and first fixing shafts are arranged in the first separation chamber, the racksare correspondingly arranged on the two sides of the inner wall of the reciprocating support, the half tooth gear connected with the first motor is arranged in the internal center of the reciprocating support, the half tooth gear is correspondingly meshed with the racks, and the first fixing shafts are arranged at the two ends of the reciprocating support; and a hydraulic device, a hydraulic rod,a first bearing, driving devices, driving mechanisms, driving rotating shafts,
polishing brushes, a second motor, a rotating shaft, a rotating sleeve, a fixed base and a receiving plate are arrangedin the second separation chamber, and the hydraulic device is arranged in the center of the top end inside the second separation chamber. The
cutting and
grinding device convenient to use has the advantages that by arranging the driving mechanisms and the reciprocating support, the
polishing brushes swing while rotating, so that the
polishing brushes are driven to carry out left-and-right
reciprocating motion to polish parts, the grinding and cutting effects of the parts are better, and the working efficiency is improved.
