Description

снаоженный каналами подвода и отвода смазочно-охлаждающей жидкости (СОЖ), отличающеес  тем, что, с целью повышени  чистоты обработки, в сверлильной головке выполнены лыска со стороны переднего угла режущей пластинки с уклоном в сторону этой нластинки и цилиндрический уплотнительный буртик, а каналыIt is equipped with channels for supplying and discharging coolant (coolant), characterized in that, in order to increase the processing purity, in the drilling head there is a flat on the side of the front corner of the cutting plate with a slope in the direction of this plate and a cylindrical sealing bead, and the channels

подвода СОЖ выведены перед буртиком в зону между пластинками, причем один из них выведен непосредственно па лыску.coolant inlet in front of the collar in the area between the plates, one of which is displayed directly on the field.
