FIELD: mining, particularly bulkheads or similar walls made of prefabricated parts and concrete.
SUBSTANCE: milling device comprises frame, support sheet connected to device frame, at least one disc cutter rotary supported by support sheet, drive arranged on device frame and spaced from support sheet, transmission mechanism connected to support sheet and driving shaft, which transmits torque from drive to transmission mechanism of support sheet. Driving shaft has thread formed on at least one section thereof. The thread is made as conveyance thread to supply lubricant to drive. Upper end of driving shaft has distribution means with sprinkling edge for further lubricant dispersion.
EFFECT: increased reliability and economical efficiency of milling device for ground cutting, decreased maintenance costs.
