Combined bed-type milling machine 6640
YOM: 1984
Manufacturer: UZTS
Made in: Russia
The machines of 6640 model are intended for processing of cast-iron, steel and nonferrous metals by face, end and disk mills. Separately adjustable drives of table feeds and milling wheelheads allow to make processing of curvilinear contours on a marking. Rotary milling wheelheads allow to make processing of the inclined planes located along an axis of a table. Grade of accuracy – Н.
