The indexable turning tool is a machine tool with indexable blade. The advantages of indexable tool are compared with the welding tool, which has the following advantages: (1) the knife's life is high because the blade avoids the defects caused by welding and blade grinding. 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 tool cost because of the tool rod service life is long, greatly reduce the consumption of the tool holder and inventory, and simplifies the management of a tool, to reduce the tooling cost. 2. Indexable turning tool blade clamping characteristics and requirements: (1) the high positioning accuracy blade transposition or replace new blade, blade the change of the position should be within the scope of the workpiece precision allowed. (2) the blade clamping reliable should guarantee the blade, knife pad, the interface fit closely, can withstand shock and vibration, but also shoulds not be too large clamping force, the stress distribution should be uniform, in order to avoid crushing blade. (3) it is best to keep the shavings smooth and easy to observe. (4) it is convenient and rapid to use the blade and replace the new blade. The structure of small size cutter should be compact. When meeting the above requirements, make the structure as simple as possible, make and use convenience.
The blade type and utility vehicle are 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. A welding tool, hard alloy welding tool called on carbon steel cutter bar is 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.
Characteristics and requirements of blade blade (1) the change of tip position should be within the range of the accuracy of the workpiece, after the positioning of the high precision blade or the replacement of the new blade. (2) the blade clamping reliable Should guarantee the blade, knife pad, the interface fit closely, can withstand shock and vibration, but also shoulds not be too large clamping force, the stress distribution should be uniform, in order to avoid crushing blade. (3) it is best to keep the shavings smooth and easy to observe. (4) it is convenient and rapid to use the blade and replace the new blade. The structure of small size cutter should be compact. When meeting the above requirements, make the structure as simple as possible, make and use convenience.
Because the tool is durable, the time is longer, the change time is shortened, the production efficiency is improved. (2) the pressure plate of the blade, which can be used as a breaker. Feature of mechanical clamping tool (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. (3) 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. (4) the pressure plate of the blade, which can be used as a breaker. Four, the indexable vehicle knife can be turned on the tool of the machine 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.
