What is the best grinding wheel to use for grinding sawtooth, and what grinding wheel can be used to

If it is a serration made of cemented carbide, a diamond resin grinding wheel is the last, and if it is an ordinary steel, a green silicon carbide grinding wheel is used. In addition, there are many issues to consider to ensure the appropriate feed amount, the selection of the particle size of the grinding wheel, and the speed of the grinding wheel to vary depending on the situation.

The general principle for selecting the hardness of a grinding wheel is to use a hard grinding wheel in order to prevent the abrasive from falling off prematurely when machining soft metals. When machining hard metals, soft grinding wheels are used in order to make the dull abrasive grains fall off in time and expose new abrasive grains with sharp edges and corners (i.e., self-sharpening).

The former is because when grinding soft materials, the working abrasive particles of the grinding wheel wear very slowly and do not need to be separated too early; The latter is due to the fact that when grinding hard materials, the working abrasive grains of the grinding wheel wear out quickly and need to be updated quickly.

In order to ensure the grinding accuracy and roughness, a slightly stiffer grinding wheel should be selected during fine grinding. When the thermal conductivity of the workpiece material is poor, and it is easy to produce burns and cracks (such as grinding cemented carbide, etc.), the grinding wheel should be softer.

Ordinary conventional serrations are ground with brown corundum.

Hello dear, I am happy to answer for you, what grinding wheel can be used to grind out rough results? When grinding with a coarse-grained grinding wheel, the production efficiency is high, but the surface of the grinding workpiece is rough; When grinding with a fine-grained grinding wheel, the surface roughness of the grinding workpiece is better, but the productivity is lower. On the premise of meeting the roughness requirements, the grinding wheel with coarse grain size should be selected as much as possible to ensure high grinding efficiency.

Generally, coarse-grained grinding wheels are used for coarse grinding, and fine-grained grinding wheels are used for fine grinding. When the contact area between the grinding wheel and the workpiece is large, the grinding wheel with coarser particle size should be selected. For example, grinding the same flat surface with the face of the grinding wheel is coarser than grinding with the perimeter of the grinding wheel.

The stainless steel adopts GC green silicon carbide grinding wheel.

A porous body made by adding a binder to the abrasive, pressing, drying and roasting. Due to the different abrasives, binders and manufacturing processes, the characteristics of grinding wheels vary greatly, so they have a significant impact on the machining quality, productivity and economy of manuscript grinding. The characteristics of abrasive belt wheels are mainly determined by factors such as abrasives, particle size, binders, hardness, structure, shape and size.

Carbon is about 30 times more capable of forming austenite than nickel, a interstitial element that can significantly increase the strength of austenitic stainless steels through solution strengthening. Carbon also improves the stress and corrosion resistance of austenitic stainless steels in highly concentrated chlorides.

Silicon carbide grinding wheel for grinding stainless steel.

When polishing stainless steel, you can choose a green carbide orange silicon balance to make a grinding wheel, and in the process of grinding, it is still necessary to add a binder, after drying and baking, to make a porous body. Because the binder includes abrasives and the manufacturing process are different, the performance characteristics of the grinding wheel are also very different, which will have a great impact on the quality of processing.

Common types of grinding wheels:

1. The grinding wheel is a shape formed by a series of operations of abrasives and binders, which has a certain strength, which is called abrasive. It is also one of the most widely used types, when used, it needs to be rotated at high speed, for some metal materials, stainless steel and other materials into the circle to stop the rough grinding or fine grinding, and even can be cut.

2. The characteristic parameters of the grinding wheel are mainly determined by its shape, size, particle size and accuracy. There are also many types of grinding wheels, if they are divided according to modulus, some are ordinary, and some are natural or harder molds.

3. According to its shape, some are cylindrical or saucer-shaped, or parallel. If it is divided according to the binder, there is a ceramic type, and there are metal types, rubber types, resin types, and so on.

4. According to the grinding effect, some are fine film or coarse grinding, and some are semi-fine grinding wheels. <>
