What are the types of turning tools and cutters in plain lathes? What materials are they cut?
Indexable turning tool is a machine tool with indexable inserts. A cutting edge can be quickly replaced by a blunt, replaced by adjacent new cutting edges, and can continue to work until all cutting edges on the blade have been blunt, and the blade is scrapped. After the new blade is changed, the turning tool can continue to work.1. advantages of indexable toolsCompared with welded turning tools, indexable turning tools have the following advantages:(1) the tool life is high, because the blade avoids the defects caused by welding and grinding, the tool geometric parameters are guaranteed by the blade and the cutter bar groove, and the cutting performance is stable, so as to improve the tool life.(2) the production efficiency is high, because the machine operator does not sharpen the knife any more, it can greatly reduce the auxiliary time of stopping, changing tools, etc..(3) it is beneficial to popularize new technology, new process, indexable knife, and to promote the use of new cutting tools such as coating and ceramics.(4) it is beneficial to reduce the tool cost. Because of the long service life of the cutter bar, the consumption and the stock of the tool bar are greatly reduced, and the management of the cutter is simplified, and the cost of the cutter is reduced.
The machine tool is a lathe tool that uses a common blade to clamp the blade on the cutter bar by mechanical clamping. This kind of knife has the following characteristics:(1) the blade is not welded by high temperature, so that the hardness of the blade and the crack caused by welding are avoided, and the durability of the tool is improved.(2) because of the increase of tool durability, the use time is long, the tool changing time is shortened, and the production efficiency is improved.(3) the knife rod can be used repeatedly, saving steel and improve the utilization rate of the blade, the blade by the manufacturer recycling, improve economic efficiency, reduce the cost of tool.(4) after the blade is re grinding, the size will gradually become smaller. In order to restore the working position of the blade, the adjusting mechanism of the blade is often arranged on the turning tool to increase the number of regrinding of the blade.(5) the end of the press plate used for pressing the blade can play the role of chip breaker.
The welding tool, is in carbon steel rod according to the requirements of a cutter angle cutter groove, with solder hard alloy blade is welded on the cutter groove, and according to the geometric parameters of the selected tool edge grinding after use.
Turning tool is one of the most widely used single edge cutting tools. It is also the basis of learning and analyzing all kinds of cutting tools.Turning tools are used on various lathes to process excircle, inner hole, end face, thread, slot, etc..The cutting tool can be divided into integral turning tool, welding tool, machine tool, indexable tool and shaping tool according to the structure. Among them, the application of indexable turning tools is becoming more and more widespread, and the proportion of indexable tools is increasing gradually
