Composite surface milling cutter capable of performing rough machining and finish machining

Abstract

The invention discloses a composite surface milling cutter capable of performing rough machining and finish machining. The composite surface milling cutter comprises a cutter head body, rough machining blades and finish machining blades, wherein one end of the cutter head body is connected with a machine tool spindle and serves as the upper end, then the other end of the cutter head body serves asthe lower end, one or more vertical installation grooves and one or more than horizontal installation grooves are uniformly formed in the lower end in the circumferential direction, moreover, the vertical installation grooves and the horizontal installation grooves are distributed at intervals, the vertical installation grooves are uniformly distributed on the circumferential surface of the lowerend of the cutter head body, the horizontal installation grooves are uniformly distributed on the end surface of the lower end, the rough machining blades are arranged in all the vertical installation grooves, the rough machining blades or the finish machining blades are uniformly arranged in all horizontal installation grooves at intervals, in the lower end face of the cutter head body, the finish machining blades are higher than the rough machining blades in the axial direction by a set amount which is taken as the finish machining allowance.

Description

technical field [0001] The invention relates to the field of milling, in particular to a compound face milling cutter capable of rough machining and finishing. Background technique [0002] Face milling cutter is a tool commonly used in milling. It is widely used in milling machine tools to process planes. Through the rotation of the tool, multiple cutter teeth cut the material in turn, so that the workpiece material is removed and the required tool is achieved. [0003] In the current plane milling of cast iron parts, in order to ensure the machining accuracy and surface roughness requirements, two stages of rough machining and finish machining are required for the machined surface. In rough machining, in order to ensure the machining efficiency, the tool needs to meet the requirements of large depth of cut, High feed characteristics to improve efficiency.

AI Technical Summary

Problems solved by technology

[0003] In the current plane milling of cast iron parts, in order to ensure the machining accuracy and surface roughness requirements, two stages of rough machining and finish machining are required for the machined surface. In rough machining, in order to ensure the machining efficiency, the tool needs to meet the requirements of large depth of cut, High feed characteristics to improve efficiency. In order to ensure machining accuracy and surface roughness in finishing machining, the tool needs to have a small depth of cut and a large cutting width to ensure the function of finishing the surface. Due to rough machining and finishing, the face milling cutter blade is different. The requirements are completely different, and the conventional face milling cutter can only be equipped with one type of blade. In order to meet the processing requirements, different face milling cutters must be used to deal with it. In this way, there are many types of cutter heads and blades, and the same part of the part is processed. Many cutting times are required, the cost of cutting tools is high, and it is difficult to improve processing efficiency.
