Application

· Mainly use for turning machine, boring, grooving and threading in NC Lathe.

cutting tool

Q: Why does a lathe tool have a rear Angle? How is its size chosen?: That is to reduce the friction between the workpiece and the rear blade. In rough machining, the material of the workpiece is smaller when the material is hard, and the finished processing or the material is softer

Q: What is the method of welding the carbide blade on the blade?: We'll brazing it with flame! Oxygen and acetylene 1 give the car knife red with borax!

Q: How to learn to sharpen a lathe?: A good skilled car worker, sharpening knife is half. This is not done overnight. Don't worry, practice the knife carefully, watch how the other person sharpens the knife. In combination with book knowledge, you can buy a mechanical worker cutting manual (mechanical worker's publisher). There is a detailed introduction to this in chapter 5 "knives". Every time you sharpen the knife, try to cut it and gradually gain experience. Hope to help you.

Q: Why is it that the knives are prone to crack when working with the parts?: Blade and slot contact surface is not smooth, if there is a black pockmark, local inequality, make welding can't form a plane combination, causing uneven distribution of solder, such not only affect weld strength and cause stress concentration, caused the blade fracture. Knowledge extension: A lathe tool is used for turning the cutting part of a cutting tool. A lathe tool is one of the most widely used knives in machining. Working part of the lathe tool is a portion of production and the processing chip, including the blade, the structure of the chip broken broken or volume approach, chip removal, or should the storage space of the chip, cutting fluid channels such as structural elements.

Q: Hello, I ask you a question, how much of an Angle will you wear with a white steel knife?: The wear of the car should increase the Angle of the knife, and also open the u-groove on the main cutting edge

Q: What is the difference between a CNC lathe and a fine turning tool?: The main difference is the grooves of the tool and the tip of the blade, and the other is a small difference in the material.

Q: What are the car knives made of?: Three faces: the front face A gamma-cutting the surface of the outflow. A alpha, the surface of the transition surface. The second knife face A alpha - the surface opposite the processed surface. Two edges: main cutting edge and side cutting edge; Tip: main cutting edge and side cutting edge. The cutting part of the lathe consists mainly of the following parts: the front face A gamma-cuttings along the outward surface. A alpha, the surface of the transition surface. The second knife face A alpha - the surface opposite the processed surface. Main cutting edge - the edge of the knife facing the front edge of the main blade. Side cutting edge - the blade of the knife facing the front of the knife. The geometrical Angle of the tool is determined in the reference frame of a certain plane, which is usually orthogonal frame reference frame, the normal frame reference frame and the assumption working plane frame reference frame

Q: What are the advantages and disadvantages of welding and machine tools?: Welding tool more economic, a common cylindrical turning tool as long as five to six dollars, you buy machine clip will be dozens of quick tool post, cutting head is also expensive, but it is easy to use, fast tool change, fast efficiency

Q: What kind of car knife makes the surface of an artifact very good?: . Due to the change of temperature, make the size change Deformation in cutting, the chip, chip of various molecules move from each other, and when they move in friction and produce a large amount of heat. Front friction, in addition, because of the chip and tool behind the cutting tool and the workpiece surface friction heat, the heat will directly affect the cutting tool and workpiece. Of course, the highest heat is the cutting (about 75%), followed by the car knife (about 20%) and the workpiece (about 4%, and 1% in the air). When the workpiece is heated, the diameter increases (about 0.01 ~ 0.05 mm, iron is changed more than steel), and then the diameter shrinks after cooling, causing the waste. It cannot be measured at high temperature. If it is necessary to side, pour enough cutting fluid in the turning, not to raise the temperature of the workpiece. The second is the method of separating from the crude. The blank is not enough to be curved without the straightening, and the center hole is deflated. The main reasons for the lack of geometry accuracy and location accuracy are not to be desired

Q: Kneel for the difference between the blade and the edge of the blade.: It is. Damping along the cutting edge is in the knife surface grinding width is small, the Angle ? o1 < 0 ? chamfer surface, enhances the tool squeeze damping effect, help to eliminate the low frequency vibration in the process of cutting. Negative chamfer width ? 1 b is associated with cutting thickness ? c, b ? usually 1 = f (0.3 ~ 0.8), take larger value when rough machining, finish machining of small value. The carbide cutting tools, take ? ? ~ o = - 5-10 ?. Vibration free edge width b ? 1 = 0.1 ~ 0.3 mm, ? o1 ? ~ = - 5-10 ?.
