There are several kinds of lathe knives for regular lathes
A turning tool is a machine tool with indexable blade. After using a cutting edge blunt can rapidly transfer to the adjacent new cutting edge, can continue to work, until all the cutting edges on the blade have been using blunt, blade to scrap recycling. After replacing the new blade, the tool will continue to work. The advantage of indexable tool Compared to the welding tool, the indexable turning tool has the following advantages: (1) the knives' service life Due to the blade to avoid the defects caused by high temperature welding and grinding, cutting tool geometry parameter entirely by the blade and tool holder slot assurance, cutting performance is stable, so as to improve the tool life. The production efficiency is high because the machine operator no longer sharpens the knife, can greatly reduce the auxiliary time such as the stop changing knife. (3) it is helpful to promote new technology and new technology, which can be used to promote the use of new tool materials such as coating and ceramics. (4) to reduce the cost of cutting tools Because of the tool rod service life is long, greatly reduce the consumption of the tool holder and inventory, simplified the tool management, reduce the tool cost.
Clamp machine tool The machine tool is used for the use of the common blade, and the blade is held in a mechanical clamping method. Such knives have the following characteristics: (1) the blade does not pass through the high temperature welding, avoiding the defects of the blade hardness caused by welding, the production of cracks, etc., which increases the durability of the tool. Because the tool is durable, the time is longer, the time of change is shortened, and the production efficiency is improved. (3) the tool holder can be repeated use, save steel and improve the utilization rate of the blade, blade by manufacturers recycling system, improve the economic efficiency, reduce the tool cost. (4) the blade after resharpening, size will gradually become smaller, in order to restore the working position of the blade, often on the tool structure is equipped with blade adjustment, in order to increase the blade grinding.
Carbide welding lathe tool A welding tool, is on the carbon steel cutter bar open groove, according to the requirement of the cutting tool geometry Angle solder will carbide blade welding in the tank, and according to the selected tool geometric parameters used after grinding.
The type and purpose of the tool The blade is the most widely used single blade cutter. It is also the basis for learning and analyzing various kinds of knives. The lathe is used for various kinds of lathe, processing outer circle, inner hole, end face, thread, car slot and so on. The structure of the tool can be divided into the overall car knife, the welding tool, the lathe tool, the turning tool and the shaping tool. The use of indexable turning tool is becoming more and more extensive, and the proportion of the blade is gradually increasing.
