Turning tool types and uses Turning tools are the most widely used single-edged tools. It is also the basis for learning and analyzing various types of tools. The turning tool is used on various lathes to process outer circles, inner holes, end faces, threads, and troughs. According to the structure, the turning tool can be divided into an overall turning tool, a welding turning tool, a machine clamping turning tool, an indexable turning tool and a forming turning tool. Among them, the application of indexable turning tools is increasingly widespread, and the proportion in turning tools is gradually increasing.
1. Carbide welding turning tool The so-called welding type turning tool is to open the sipe on the carbon steel arbor according to the geometrical requirements of the tool, and weld the cemented carbide insert into the sipe with solder, and according to the selected The turning tool used after the geometric parameters are sharpened.
Second, the machine clamp cutter is a utility knife that uses a common blade to clamp the blade on the cutter bar by mechanical clamping. This type of knife has the following characteristics: (1) Due to the increased durability of the tool, the use time is longer, the tool change time is shortened, and the production efficiency is improved. (2) The end of the pressure plate used for pressing the blade can function as a chip breaker.
Mechanical clamp type turning tool features
(1) The blade is not subjected to high-temperature welding, which avoids defects such as hardness drop and cracking caused by welding, and improves the durability of the tool.
(3) After the blade is reground, the size will gradually become smaller. In order to restore the working position of the blade, a blade adjustment mechanism is often provided on the turning structure to increase the number of re-grinding of the blade.
(4) Pressing the end of the platen used for the blade can function as a chip breaker. 4. Indexable turning tool The indexable turning tool is a machine clamping cutter that uses an indexable insert. After a cutting edge is blunt, it can be quickly indexed and replaced with an adjacent new cutting edge to continue working until all the cutting edges on the blade have been blunt, and the blade is scrapped and recycled. After replacing the new blade, the turning tool can continue to work.
