Description

Single-head spindle numerical control machine tool with movable tool rest

Technical Field

The utility model relates to the technical field of numerical control machine tools, in particular to a single-head spindle numerical control machine tool with a movable tool rest.

Background

The numerical control machine tool automatically processes the processed parts according to a processing program programmed in advance. The machining process route, the process parameters, the movement track, the displacement, the cutting parameters and the auxiliary functions of the part are compiled into a machining program list according to instruction codes and program formats specified by a numerical control machine, the content in the program list is recorded on a control medium and then is input into a numerical control device of the numerical control machine, so that the machine tool is instructed to machine the part, and the numerical control machine is one of the numerical control machines which are widely used at present. The numerical control lathe is mainly used for cutting processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of any cone angle, complex rotary inner and outer curved surfaces, cylinders, conical threads and the like, grooving, drilling, reaming, boring and the like can be performed, for some parts needing turning and turning for many times, a conventional numerical control lathe can only turn or mill the parts, and another numerical control lathe needs to be placed for turning after the processing is finished, so that the processing precision of parts can be reduced, and therefore a single-head main shaft numerical control lathe with a movable tool rest needs to be used for processing.
