Sharpening a knife for a meat grinder at home

A meat grinder is an indispensable tool in the kitchen. With its help, you can easily grind any product needed to prepare a delicious dish. However, gradually the grinder knives grind off. In such situations, their sharpening is required. Can this be done on my own?

Training

Sharpening a knife for a meat grinder is a simple process. However, before starting work, you should carefully prepare the part and tools. The meat grinder knife and grill should be thoroughly washed. After this, the part should be greased with vegetable oil and left for five minutes. During this time, the knife should dry slightly.

Grinding a knife for a meat grinder: the main methods

Before you start sharpening a knife, you should decide on the method. There are several main ways, among which:

1. Sharpening knives and grill grinder with a special machine.
2. The use of a grindstone.
3. Using sandpaper.

Each of the methods has its own advantages and disadvantages. If desired, you can choose the method that is most convenient.

The use of a special machine

Sharpening a knife for a meat grinder with a special machine is the most convenient method. The fixture is equipped with a smooth surface coated with an abrasive compound. It looks very much like a disk. Before sharpening, a special paste must be applied to this surface. The tool has in its composition small abrasive particles. The paste dries quickly enough. After applying this tool, the disc becomes rough.

When the tool is ready to work, you must run it. After starting, the disc will begin to spin. The knife from the meat grinder must be carefully pressed with the blade to the surface of the circle. Sharpening in this case is carried out in several stages. Indeed, in the process, the metal can become very hot. Breaks are required in order for the blade to cool.

The disadvantages of this method

Sharpening a knife for a meat grinder with a special machine has several disadvantages. Among them it is worth highlighting:

1. The difficulty of sharpening with insufficient experience. Anyone who has never done such a job can not determine exactly at what angle the grinder blade needs to be ground. In addition, for beginners, this can be unsafe. For this reason, sharpening a knife for a meat grinder should be carried out only by professionals.
2. The cost of the machine. Prices for such designs are quite high. At the same time, it is almost impossible to purchase a machine in an ordinary store. Therefore, when choosing a knife sharpening method, you should consider whether it is worth spending money on special equipment.

Grindstone application

In this case, the grinding of knives for a meat grinder at home is carried out using a grindstone. For sharpening, you should take a grindstone, the surface of which has an area several times larger than the diameter of the part. The fraction should be sufficiently small. Otherwise, sharpening quality will suffer or more time will be spent.

The meat grinder knife must be placed on the surface of the grindstone so that it fits snugly against it. After that, the part must be held in a circle with your finger in the center. At the same time, it is necessary to exert pressure on the knife. Gradually, the rotation speed should be increased.

Features of this method

When sharpening knives using this method, it is worth checking the blade periodically. If there are no gaps and chips on it, then the procedure can be considered completed. The knife should become more uniform. However, when choosing a sharpening method, it is worth considering that this method is only suitable for slightly dull blades. If the knife is completely worn out, then a cardinal approach is required.

The second method of sharpening with a grindstone

In this case, the grinding stone itself rotates. There is no need to buy a machine for sharpening knives for a meat grinder. For work, you can use a tool that in size corresponds to the diameter of the blades. The surface of the grindstone must have a fine fraction. Due to friction of surfaces sharpening will be carried out.

Before starting work, wear a glove to protect your hand. After that, the grinder must be pressed firmly against the grinder knife. The tool must be rotated in a circle. If possible, it is better to fix the knife so as not to hold it in your hands. After sharpening, the part should cool slightly. To do this, the knife can be placed under a stream of cold water. This will also remove metal fragments. This method is suitable for sharpening very dull blades.

Using sandpaper

Experts do not recommend doing something on their own if you do not know how to sharpen knives for meat grinders. In St. Petersburg, Moscow and major cities there are special companies that deal with such things on a professional level. If there is no such organization in your city, then you can use sandpaper for sharpening.

The thickness of the material depends on the thickness of the knife. Coarse sandpaper is required for thick metal. First you need to pick up the dull part. Now you should rub each blade of the part with sandpaper. Repeat the procedure until the knife is sharp enough. Finally, the part should be washed in running water to remove metal fragments.
