DEVICE FOR COMBINED GRINDING Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has sectional noncontinuous abrasive wheel made in the form of coarse- and fine-grained abrasive members fixed on flexible band arranged on projections of body. Abrasive members are coupled with mechanism of their radial movement. The mechanism is flexible bottle filled with ethyleneglycol. Electric heating element is placed inside the bottle. Preliminary grinding step is performed by means of coarse-grained members, and final step is carried out by fine-grained members when heating element is supplied with current. The construction provides for clearance-free connection of body with fine-grained members during automatic transition from one grinding step to the other. EFFECT: enhanced accuracy of working. 3 dwg
