Can external rolling mirror machining for lathes replace grinding machining?

Rolling mirror surface is processed once with a grinding machine and then rolled into a mirror.

Metal rolling machine, fast and efficient.

I did bookmark a tutorial that I hope will be useful to you. If you do, don't forget it.

Hello, Jinan Shengrui Ultrasound's ultrasonic metal nano equipment can! The equipment is installed on the lathe tool holder, and the workpiece after the turning is processed can be processed once with this equipment to improve the surface roughness of the workpiece to the mirror level! Moreover, the workpiece processed by it not only releases the internal residual stress, but also forms the surface compressive stress, and the surface hardness is also improved to varying degrees, which can greatly increase the service life of the workpiece, and is the most ideal solution to solve the problem of surface roughness of the workpiece, welcome to learn more!

How to grind a single-wheel rolling knife for lathes, the sharpening of ordinary lathe turning knives generally has two types: mechanical sharpening and manual sharpening. The mechanical grinding efficiency is high, high-quality, easy to operate, and it is more widely used in factories with conditions. Manual grinding is flexible, the equipment requirements are low, and ordinary lathes are still commonly used.

For a turner, hand sharpening is the foundation and a basic skill that must be mastered. (1) Selection of grinding wheelThere are two kinds of grinding wheels commonly used in the factory: one is the alumina grinding wheel, and the other is the green silicon carbide grinding wheel.

When grinding, the type of sand wheel must be determined according to the tool material. The alumina grinding wheel has good toughness and sharpness, but the hardness is slightly lower, and it is used to sharpen the shank part of high-speed steel turning tools and carbide turning tools. The green silicon carbide grinding wheel has high sand hardness and good cutting performance, but it is brittle, and is used to sharpen cemented carbide turning tools.

2) The steps and methods of sharpening are now based on the entering angle of 90. For example, the steel turning tool (YTL5) introduces the steps of manual grinding, 1) first grind the welding slag on the rake face and rake face of the turning tool 2) rough grind the shank part of the main rake face and the secondary flank face. Its trailing angle should be 2 larger than the trailing angle of the blade.

3。in order to sharpen the rake angle on the blade, and 3) coarsely sharpen the main and secondary flank faces on the blade. The main and secondary relief angles should be about 2 degrees larger than the required rear angles, and 4) grinding chip breakers.

In order to break the chips, a chip breaker groove is generally ground in front of the turning tool. Chipbreakers come in three shapes, i.e., linear, round, and straight. For example, the turning tool of the arc-shaped chip breaker must be trimmed into a suitable arc at the intersection of the outer circle of the grinding wheel and the plane.

If the grinding of a linear chipbreaker is carried out, the angle of the grinding wheel must be sharpened. When sharpening, the tip can be moved down or up. Precautions for grinding chip breakers The grinding wheel corners of grinding chip breakers should always be sharp or have small fillet corners.

When there is a large fillet on the grinding wheel, the grinding wheel should be trimmed with a diamond pen in time. Do not use too much force when sharpening. The turning tool should move smoothly up and down in the direction of the tool holder.

Chipbreaker grinding can be carried out on both flat and cup grinding wheels. For the larger chip breaker, it can be divided into coarse grinding and fine grinding, and the smaller chip breaker can be ground and formed at one time. When the chip breaker is finely grounded, the conditional plant can be carried out on the diamond grinding wheel.

5) The method of fine grinding of the main flank face and the secondary flank face. When grinding, the cutting edge of the turning tool should be gently pressed against the end face of the grinding wheel, and the turning tool should move slowly from side to side to make the grinding wheel wear evenly, and the cutting edge of the turning tool is straight and smooth. 6) Grinding negative chamfer, in order to make the cutting edge strong, the cemented carbide turning tool for processing steel is generally ground out of negative chamfering.

7) Sharpen the transition edge. There are two kinds of transition edges: straight and round, and the sharpening method is basically the same as that of fine grinding flank face. When sharpening turning tools for harder materials, it is also possible to sharpen negative chamfers on the transition edges.
