FACILITY FOR CUTTING OF MATERIAL Russian patent published in 2009 - IPC B28D1/04 

FIELD: machine building.

SUBSTANCE: invention refers to facilities for cutting of mainly natural or artificial stone and simultaneous removal of wastes including dust from zone of cutting. The facility consists of a bed, of a case hinged to the bed, of a disk element arranged in the case; also the disk element is connected to an electric engine; an air pump with a turbine for removal wastes from the zone of cutting is installed in the case and connected to the electric engine. The case of the pump creates a working cavity communicated with atmosphere via an air branch of the case and communicated with a flexible air duct via an outlet branch; the flexible air duct is connected with a container for wastes collection. The case is made semi-spherical with a movable bed made out of parallel and rigidly connected between them plates so, that formed air cavity between the plates of the bed and air cavity of the case are communicated. A spindle with a cutting element attached to it is arranged in the cavity of the case; the spindle is secured to the case by means of a reducer whereto the case of the air pump is rigidly connected; the cavity of the case and the cavity of the air pump case communicate so, that that the wall of the pump case interfaced with the wall case form the working cavity of the pump. Connection of electric engine with the air pump and cutting elements is performed by means of the first and the second reducers each made one-stepped; the step of the reducer connected to a cutting element consists of a drive gear assembled of the shaft of the electric engine and meshing with a tooth wheel arranged on the spindle. The step of the second reducer consists of a driven gear arranged on the shaft of the air pump turbine installed in its case. The driven gear meshes with a tooth wheel. Axes of gears are arranged at angle within ranges of 90÷130°, while the shaft of the electric engine is assembled at angle of 0÷90° to the support surface of the bed.

EFFECT: increased compactness and usability.
