Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing tools, in particular to a split combined milling cutter for processing door frame columns. Background Art

[0002] The mast column of a forklift is a vertical column that supports the mast structure of the forklift. It mainly supports and stabilizes the mast to ensure the overall stability and carrying capacity of the forklift. Existing forklift mast columns are usually processed with an integrated combination milling cutter. This integrated combination milling cutter has the following main disadvantages in actual use: 1. The inner and outer surfaces of the mast column are processed by two different combination milling cutters. After processing one side of the mast column, the milling cutter is replaced to process the other side of the mast column. Since the integrated combination milling cutter is heavy, it usually takes two people to replace the entire tool including the handle, which is time-consuming and labor-intensive; 2. After replacing the entire tool, the tool positioning and calibration work needs to be re-performed, which will not only prolong the processing time but also affect the processing dimensional accuracy.
