Technical Field
[0001] This utility model relates to the field of milling cutter technology, and in particular to a high-gloss PCD milling cutter. Background Technology
[0002] In the field of high-gloss component processing, there are high requirements for the machining accuracy, efficiency and service life of cutting tools.
[0003] Traditional milling cutters often require multiple tools to process end faces, hole walls, and grooves in multiple passes, resulting in low processing efficiency. Furthermore, traditional inserts are mostly welded, which can easily lead to tool body deformation, affecting machining accuracy. Replacement of worn inserts requires re-welding, which is time-consuming, labor-intensive, and increases production costs. In addition, traditional tools often lack dynamic balance, leading to vibrations during high-speed machining and affecting the quality of high-gloss surfaces. Therefore, we propose a high-gloss forming PCD milling cutter to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-gloss PCD milling cutter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-gloss PCD end mill includes a shank and a cutter body fixedly mounted on one side of the shank, with a positioning mechanism between the shank and the cutter body. The cutter body has a first cutting section and a second cutting section, with the first cutting section located to the left of the second cutting section. The second cutting section has multiple detachable insert assemblies. Each insert assembly includes a groove, an insert, and a clamping plate. The outer surface of the second cutting section has multiple grooves, in which inserts are installed. A clamping plate for clamping and fixing the insert is installed on the side of the insert away from the second cutting section, and a locking mechanism is provided between the clamping plate and the cutter body.
[0006] Preferably, the blade has multiple mounting holes 1, and the pressure plate has multiple mounting holes 2, and the mounting holes 2 are adapted to the corresponding mounting holes 1.
[0007] Preferably, the locking mechanism includes a bolt groove and a locking bolt. The inner wall of the slot is provided with a bolt groove, and the locking bolt is installed on the pressure plate. The locking bolt passes through the corresponding mounting hole one and mounting hole two and is threaded into the corresponding bolt groove.
[0008] Preferably, a plug groove is provided on one inner wall of the blade groove, and the side of the plug groove away from the second cutting part is set as an opening, and a plug seat adapted to the corresponding plug groove is installed on the pressure plate.
[0009] Preferably, the positioning mechanism includes a positioning groove and a positioning rod. The positioning groove is provided on one side of the blade body, and the positioning rod is installed on one side of the blade handle, and the positioning rod is adapted to the corresponding positioning groove.
[0010] Preferably, the number of blades is set to eight, the eight blades are equally spaced, and the blades are made of alloy.
[0011] The beneficial effects of this utility model are: 1. By integrating cutting part one and cutting part two on the tool body, it is possible to complete the machining tasks of end face machining, hole wall machining, and tool groove machining, reduce the number of tool changes, shorten the machining cycle, and at the same time avoid the errors caused by multiple tool settings, thereby improving machining accuracy; 2. The long blade is fixed by a mechanical clamping plate, replacing the traditional welding process. The blade is locked with high strength by the double limit of the locking bolt and the plug seat, while avoiding the deformation of the blade body caused by the high temperature of welding, thus ensuring the stability of the tool in long-term use. 3. The blade is fixed to the locking mechanism by a detachable pressure plate. When the blade is worn, the blade can be replaced simply by removing the locking bolt and the pressure plate. There is no need to re-grind the blade body or replace the entire blade, which greatly reduces maintenance costs and equipment downtime. Attached Figure Description
