Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a high-precision milling cutter for processing thin-walled aluminum parts. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. Each tooth cuts off the excess of the workpiece intermittently in sequence during operation. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines.

[0003] However, during the use of the existing high-precision thin-walled aluminum processing milling cutter, since the milling cutter is made of metal material, and the metal material itself is easily expanded by heat, when the high-precision thin-walled aluminum processing milling cutter is used to process the object, the milling cutter will generate friction with the object, and at this time the milling cutter will generate a large amount of heat. Under the action of long-term processing of the object, the milling cutter will be deformed due to excessive heat. At the same time, the milling cutter cannot cut off the processed metal chips, making it difficult to discharge the metal chips and scratch the processing part, resulting in a decrease in the processing accuracy of the workpiece. For this reason, we have designed a high-precision thin-walled aluminum processing milling cutter to solve the above problems. Summary of the invention

[0007] Preferably, six end tooth finishing edges are provided, the six end tooth finishing edges are the same in size, and the six end tooth finishing edges are arranged at equal intervals.

[0012] Preferably, the blade body includes a hollow portion at one end of the blade body and a handle at the hollow portion at the other end as an integrated structure.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the high-precision thin-wall aluminum processing milling cutter, through the metal coating and cutting groove, when the high-precision thin-wall aluminum processing milling cutter is used, since the metal coating is processed by Ti-Al-XN coating material, and the Ti-Al-XN coating is coated on the outer surface of the blade by a vapor deposition method, the Ti-Al-XN coating can act as a chemical barrier and a thermal barrier, and enhance the hardness, wear resistance, chemical properties and heat and oxidation resistance of the blade, and reduce the friction coefficient and thermal conductivity of the blade, so that when the milling cutter generates friction when processing a workpiece, the heat generated by the blade can be reduced, and deformation of the blade due to excessive heat is avoided. At the same time, the processed metal cuttings will be cut off by the cutting groove, so that the metal cuttings can be quickly discharged through the high-precision polishing chip removal groove, and the friction between the milling cutter and the object is avoided. Heat deformation, thereby increasing the processing area and the metal cuttings are not easy to be discharged and scratch the processing area, thereby improving the processing accuracy of the high-precision thin-wall aluminum processing milling cutter.

[0022] In this embodiment, six end tooth finishing edges 9 are provided. The six end tooth finishing edges 9 are the same in size and are arranged equidistantly. The end tooth finishing edges 9 are used to quickly process the processing parts.

[0023] More specifically, the metal coating 301 is made of Ti-Al-XN coating material, and the thickness of the metal coating 301 is six to seven microns. The metal coating 301 can enhance the hardness, wear resistance, chemical properties, heat resistance and oxidation resistance of the blade 3, and reduce the friction coefficient and thermal conductivity of the blade 3.

[0024] The blade body 3 is made of alloy material, and the blade body 3 is a solid structure. The blade body 3 made of alloy material is more durable and not easy to be damaged.

[0025] More specifically, a plurality of cutting grooves 6 are provided, and the plurality of cutting grooves 6 have the same size. The cutting grooves 6 can cut off the metal chips, thereby preventing the metal chips from being difficult to discharge and clogging the processing area.

[0026] In this embodiment, the blade body 3 includes a small cylindrical ligament 4 for measuring the blade on the outside of the blade body 3 and a high form tolerance inverted cone 5 for measuring the blade at the center of the outside of the small cylindrical ligament 4 for measuring the blade, which are an integrated structure.

[0028] Working principle: After the utility model is installed, first check the installation and safety protection of the utility model. When using a high-precision thin-walled aluminum processing milling cutter, since the metal coating 301 is made of Ti-Al-XN coating material, and the Ti-Al-XN coating is coated on the outer surface of the blade 3 using a vapor deposition method, the Ti-Al-XN coating can act as a chemical barrier and a thermal barrier, and enhance the hardness, wear resistance, chemical properties and heat and oxidation resistance of the blade 3, and reduce the friction coefficient and thermal conductivity of the blade 3. When the milling cutter generates friction when processing the workpiece, it can reduce the heat generated by the blade 3, avoiding deformation of the blade 3 due to excessive heat. At the same time, the processed metal cuttings will be cut off by the cutting groove 6, so that the metal cuttings can be quickly discharged through the high-precision polishing chip groove 7, thus completing the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
