Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a chip removal and cleaning device for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are one of the most widely used CNC machine tools. They are mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. According to the bed, the machine tool can be divided into two types: flat bed and inclined bed. The plane where the two guide rails of the flat bed CNC machine tool are located is parallel to the ground plane. The plane where the two guide rails of the inclined bed CNC machine tool are located intersects with the ground plane to form an inclined plane.

[0003] However, since the existing flat-bed machine tools have a planar structure as a whole, waste chips can easily enter the lead screw and the slide rail groove during processing, making it difficult to remove chips. The operator is required to assist in cleaning the internal waste chips after processing, which brings inconvenience to use. Therefore, it does not meet the existing needs. In this regard, we propose a chip removal and cleaning device for CNC machine tools. Utility Model Content
