Ordinary end mills have the same blade diameter and shank diameter, for example, the blade diameter is 10mm, the shank diameter is 10mm, the blade length is 20mm, and the overall length is 80mm.
The deep groove milling cutter is different. The blade diameter of the deep groove milling cutter is usually smaller than the shank diameter. There is also a spin extension between the blade length and the shank length. This spin extension is the same size as the blade diameter, for example , 5 blade diameters, 15 blade lengths, 4wa0 spin extensions, 10 shank diameters, 30 shank lengths, and 85 total lengths. This kind of deep groove cutter adds a spin extension between the blade length and the shank length, so it can process deep grooves.
Advantage
1. It is suitable for cutting quenched and tempered steel;
2. Using TiSiN coating with high coating hardness and excellent heat resistance, it can exert excellent performance during high-speed cutting;
3. It is suitable for three-dimensional deep cavity cutting and fine machining, with a wide variety of effective lengths, and the best length can be selected to improve quality and efficiency.
Disadvantage
1. The length of the tool bar is fixed, and it is inconvenient to use when machining deep grooves of different depths, especially when machining deep grooves with shallow depths, because the length of the tool bar is too long, it is easy to break the tool bar.
2. The surface of the tool tip of the tool head is not provided with a protective layer, which makes the tool tip easy to wear, which leads to diffusion between the workpiece and the workpiece during processing, and affects the service life of the tool head.
3. The cutter head will vibrate during cutting, which will destroy the surface quality of the workpiece, so that the surface smoothness of the workpiece cannot meet the requirements.
4.The waste generated during the processing is not easy to discharge, and accumulates at the cutter head, which affects the cutting of the cutter head.
Deep groove tool life
The most important thing is that the cutting amount and the cutting amount are closely related to the tool life of the deep groove cutter. When formulating the cutting amount, a reasonable deep groove tool life should be selected first, and a reasonable deep groove tool life should be determined according to the optimization goal. Generally, there are two types of tool life with the highest productivity and the lowest cost tool life. The former is determined according to the goal of the least man-hours per piece, and the latter is determined according to the goal of the lowest cost of the process.
