Will the grinder sharpen the knife break the steel, and will the knife sharpened by the grinding whe

Grinders. Sharpening knives can damage the steel because the steel friction generates heat during the grinding process, which can lead to annealing.

The grinder is a common equipment used to sharpen various knives and tools. It is mainly composed of a base, a grinding wheel, an electric motor or other power source, a bracket, a protective cover and a water feeder.

Precautions. 1) The thickness of the grinding wheel should be selected according to the material and processing schedule requirements of the device to be processed. Coarser grinding wheels should be used for softer metal materials, such as copper and aluminum, and thinner grinding wheels should be used for devices that require higher machining accuracy.

2) According to the shape to be processed, select the appropriate grinding wheel surface.

3) The grinding wheel used shall not have cracks, defects and other defects or disabilities, and the installation must be stable. This point should also be paid attention to at all times during use, once the grinding wheel is found to have cracks, defects and other defects or disabilities, immediately stop using and replace with a new product; When moving, it should be stopped immediately for tightening.

4) When grinding, the operator should wear protective glasses to prevent the injury of flying metal chips and sand particles to the human body.

5) The pressure applied to the grinding device should be appropriate, too much will produce overheating and annealing the machined surface, and it will not be able to be used in serious cases, and at the same time cause the life of the grinding wheel to be reduced too quickly.

6) For devices with a width smaller than the grinding surface of the grinding wheel, in the grinding process, do not always grind at one part of the grinding wheel, but should translate left and right on the grinding surface of the grinding wheel for a certain period, so that the grinding surface of the grinding wheel can be kept relatively flat and convenient for future processing.

7) In order to prevent the overheating and annealing of the machined surface of the grinding device, the grinding part can be cooled in deep water at any time.

8) Measure the insulation resistance of the motor regularly.

It should be guaranteed not less than 5m).A circuit breaker with leakage protection should be used to connect to the power supply.

First of all, it will definitely be, the simple way to distinguish is that you see if the knife will change color when grinding, if the color will destroy the hardness of the knife, which is commonly known as breaking the fire, to ensure that the fire is not broken, you have to grind when you don't grind a lot of area or a lot of force, and then grind it can be dipped in water for cooling, of course, it depends on your actual experience, just grind a few more times.

Hello <>

There will be small notches in the knife sharpened by the grinding wheel. The grinding wheel is a tool used to grind the surface of the metal, and in the process of use, due to the different materials and hardness of the metal, the cutting edge of the tool will also be notched due to different degrees of wear. Therefore, the knife sharpened by the grinding wheel will generally have a small gap in the process of use.

1.The grinding principle of the grinding wheel is to remove the metal burrs and frontal wear by scraping the abrasive particles on the surface of the tool, but excessive grinding force can cause excessive wear or other unevenness. 2.

The cutting edge notch and wear degree of the tool are not only related to the nature of the grinding wheel, but also related to the different grinding operations, polishing and coating treatments of the grinding wheel, so when using the grinding wheel for the branch key, it is necessary to select the corresponding abrasive according to the factors such as the material, hardness and type of adhesive to be grinded. 3.Checking and maintaining the quality of the cutting edge of the tool is an important factor to ensure the cutting quality.

Once there is a notch in the cutting edge, it needs to be trimmed and ground in time to avoid affecting the service life and performance of the tool. <>

Hello, grinding wheels can cause very small notches on the surface of the tool. Since grinding wheel grinding is done by weakening the edge metal early in the grinding process by trapping abrasive particles, irregular depressions occur on the surface of the cutting edge, which are often referred to as depressions"Abrasion marks"or"Abrasive terrain"。These small notches are not visible, but their presence can impair the sharpness of the cutting edge and reduce the cut quality of the gauge transport.

To minimize the impact of grinding wheels and notching problems, use high-quality grinding wheels, the right grinding tools and the right grinding methods, follow the correct grinding process and sequence, and polish and trim the tool after grinding to ensure smooth cutting edges and minimize notching. In addition, for tools that require high-precision machining, other processing methods, such as electric beam spark machining, laser processing, etc., can be used to avoid the occurrence of notch problems.

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.

Summary. I'd like to give you two suggestions.

I'd like to give you two suggestions.

1. Replace the new bearing 2 to clean the equipment and clean up the foreign matter.

Is it okay to send **.

Yes, you can send it to me.

That's it. I feel like the blade is a little crooked, dear.

I'm sure I'll only wear out one place.

It should be that the bearing is not working.

The knives are crooked. You take the knife apart and put it back on.

Clean up the foreign object.
