Background

At present, a common machining method for machining non-ferrous metal planes such as aluminum alloy, copper alloy and the like in the market is to adopt a milling cutter disc to machine, the traditional milling cutter disc comprises a disc body and a plurality of milling cutters arranged on the disc body, the disc body is used for clamping the milling cutters and fixed at the end part of a main shaft, and the plurality of milling cutters are arranged on the side edge of the disc body far away from the main shaft at a certain radial distance from the central line of the main shaft. When a workpiece is machined, the main shaft drives the disc body to rotate, the milling cutter performs circular motion around the central line of the main shaft and cuts the workpiece, the problem of cutter disc vibration exists due to large cutting amount when the milling cutter disc machines the end plane of the workpiece, the impact damage to the cutter is serious, and the service life of the cutter is greatly shortened.

Meanwhile, the conventional milling cutter disc is usually machined by a hard alloy cutter, and the service life of the cutter is much shorter than that of a polycrystalline diamond cutter. Under the condition, when the requirements on the processing quality and the service life are higher, the requirements of customers can not be met by adopting a common hard alloy blade milling cutter head cutter or a whole hard alloy cutter, and due to the fact that the service life of the hard alloy blade is lower, the blade needs to be replaced frequently, the machine tool is too long in downtime, the production cost is increased, and the production efficiency is seriously influenced.

In order to solve the above problems, people are always seeking an ideal technical solution.

Based on the above, the PCD face milling cutter tooth comprises a hard alloy substrate and a polycrystalline diamond layer coated on the surface of the hard alloy substrate.

Based on the above, the PCD face milling cutter teeth are fixedly attached to the cutter tooth mounting positions through the hard alloy substrate.

Based on the above, the bottom surface of the chip groove extends along the axis of the cutter head, the bottom surface of the chip groove is perpendicular to the side wall of the chip groove, and a convex ridge section is formed between every two adjacent chip grooves.

Based on the above, the end tooth cutting edge and the outer diameter cutting edge are smoothly transited to the convex ridge section through a transition circular arc R.

Based on the above, the top surface of the PCD face milling cutter tooth is flush with the side wall of the chip groove.

Based on the above, the plurality of chip grooves in the HSK 63-based integral PCD face milling cutter are arranged on the cutter head at equal intervals.

Compared with the prior art, the utility model has the advantages of substantive characteristics and progress, specifically speaking, the utility model provides a because the whole PCD face milling cutter of HSK63 handle of a knife adopts the compound piece of PCD as face milling cutter's sword tooth, can utilize the high rigidity that compound piece of PCD self had, high wear resistance, good heat conductivity and stronger impact toughness to improve milling cutter's life and the machining precision who improves the work piece.

Furthermore, a plurality of PCD face milling cutter teeth are obliquely arranged in the chip groove, namely the included angle value between the outer diameter cutting edge and the axis of the cutter head is 0-15 degrees; the included angle value between the end tooth cutting edge and the diameter normal direction of the cutter head is 0-8 degrees, so that the cutter teeth are gradually contacted with the end face of a workpiece in a slant manner when the milling cutter with the structure is used for face milling, the meshing between oblique gears is similar, the vibration phenomenon in the face milling process is reduced, and the impact damage of the workpiece to the cutter is further reduced. Therefore, the utility model provides a based on whole PCD face milling cutter of HSK63 handle of a knife can be applicable to the end plane processing of non ferrous metals such as aluminum alloy, copper alloy, can effectively improve the processingquality of work piece and the life of cutter, has wide application prospect.
