Description

Technical Field

[0001] The utility model relates to the technical field of roller feeding, in particular to a feeding mechanism of a numerically controlled roller lathe. Background Art

[0002] Rollers refer to tools in lathes that continuously act on metal and deform it. Rollers can be divided into steel rolls, cast iron rolls and carbide rolls according to their materials. CNC roll lathes can be used for rolls of various materials, and can also perform various rough and fine processing through composite rolls.
