THE DEVICE FOR ABRASIVE BLAST TREATMENT OF DIMENSIONAL SURFACES OF WORKPIECES AND THE METHOD FOR TREATMENT OF DIMENSIONAL SURFACES OF WORKPIECES USING THIS DEVICE

摘要

The object of the invention is a device for abrasive blast treatment, comprising a housing providing working space, with a filter-ventilation system, a multi-part kinematic mechanism comprising a rotatable telescopic assembly, a means of feeding the abrasive jet adapted to move with the moving part of the telescopic assembly and a system for recirculating the abrasive, characterized in that the means for feeding the abrasive jet is an impact turbine feeding the abrasive jet is provided with at least four degrees of freedom and is designed to feed the abrasive jet at any point in the working space inside the housing. The subject of the invention is also the method of treatment the dimensional surfaces of workpieces with the device.
