Currently, many machines use tools such as cutters in the industrial industry. There are various types of product data . They are used in turning, planing, turning and revolving, grooving, special machines.
Cutters are classified according to the type of work that they perform, that is, they are cutting, boring, boring, threaded, cutting, shaped. Let's consider in more detail a cutting tool.
Description and design features
The cutting tool is used in lathes for cutting metal products and making narrow grooves in parts. This device may have a different design. For each type of turning work, special types of cutters are used . It all depends on the type of processing. So, for example, the recesses in the parts are carried out using a groove cutter. The cutting head of such a device is similar to the shape of the groove being made. It all depends on the size of the required recess. When using hard metal, you have to perform several passes in order to make a groove.
Cutting turning cutters are divided according to the following characteristics.
- In the direction: right and left, bent and straight.
- By type of metal finish: cutting tool for roughing, finishing and fine machining.
- By sectional shape: round, square and rectangular.
- By the difference in installation relative to the part: radial and tangential cutters.
- Still these devices differ depending on the design of the device for breaking chips and the material from which they are made.
The cutting tool operates in difficult conditions. Any unnecessary load can lead to the failure of this device as a result of the fact that its working surface is too small. With proper sharpening and installation of the cutter, you can avoid breaking it. To increase the life of this product, solder the plate into a grooved corner groove. To prevent breakage of the cutting tool or defect of the protrusion at the end of the part, the cutter should be installed no higher and no lower than the axis. The processing of brittle materials is carried out at an angle of about 5-10 °.
Cutting lathe cutter - product installation
This process is not too complicated. Whole metal cutters are very common, and these devices with a carbide brazed plate are used a little less often. Since in operation the head of this product is subject to strong lateral friction, it must be narrowed by 1-2 degrees. And they mount such a device to the turned object at a right angle. An essential point during installation is the location of the cutting tool exactly in the center of the part. This is important in this case. In turning operations with brittle materials, the cutting tool used is installed at small angles of 5-10 degrees. Otherwise, the processed bar may break. For high-speed devices, the operating speed should be in the range from 25 to 30 m / min, and for these products with brazed carbide, from 125 to 150 m / min.
Tip
It should be remembered that the cutting tool must be correctly installed and sharpened, otherwise it may fail. To increase the strength and stiffness of the head of the specified product, its height is greater than that of the rod. It is also necessary to know that in order to prevent tearing from the holder of the plate, it is advisable to solder it in the corner groove, which will lead to an increase in its contact area and the operational life of the cutter.
