Basic spare parts for meat grinder
Mechanical and electric meat grinders have similar cutting parts, consisting of two parts:
- rotary cutter with blades;
- fixed mesh knife, which is also called a grid.
Knife materials
The cutting surfaces of modern meat grinders are made of stainless steel, stainless steel or tool carbon steel.
The wear resistance of a knife for an electric meat grinder is increased by coating it with a special alloy that contains chromium and cobalt with the addition of tungsten or molybdenum. The alloy gives strength and long service life to the part without sharpening.
Expensive self-sharpening knives made of improved tool steel are used in industrial meat grinders. They are quite expensive and it is not economically feasible to use them in household appliances. A household meat grinder with a stainless steel cutting unit will function properly for 1-2 years without replacement.
Types of cutters
Movable cutters for meat grinders differ:
- by the number of blades;
- according to the shape of the blades;
- according to the configuration of the hole for attaching the knife to the auger.
Cutters for household meat grinders often have 4 blades. This number of blades is ideal for preparing minced meat for cutlets and meatballs. The shape of the blades can be straight or curved. Knives with curved blades cut wires more easily and prevent them from wrapping around the auger, which makes the shaft easier to operate and extends the service life of the device. Cutters with double-sided sharpening will last longer than single-sided ones made of the same material.
Cutters for industrial meat grinders are distinguished not only by a wide variety of blade shapes and sizes, but also by the manufacturing method: they are most often not stamped, but forged and self-sharpening. The number of blades varies from 2 to 8. The shape is straight, curved and crescent-shaped . Knives are often equipped with replaceable blades.
Self-sharpening forged blades made of tool steel can also be selected for a household meat grinder; for this you need to know the size and configuration of the cutting hole, as well as the dimensions of the blades.
The mounting holes have the following shape:
The sizes of the holes also vary, so you need to know the exact parameters of the mounting location of the device for which the knife is selected.
Cutting meshes
The second part of the chopping block of the meat grinder is the grid or mesh knife. The performance of the unit and the quality of the minced meat obtained depend on the number of holes and the sharpness of the cutting edge. Household appliances are most often equipped with three grids:
- A disk with holes with a diameter of 7-10 mm, which is used in the production of minced meat for homemade sausages. This grid is also used when grinding hard cheeses and dried fruits.
- A universal disk with holes 4-6 mm in diameter. It is indispensable when obtaining minced meat for cutlets, meatballs and meatballs.
- A grid with small holes with a diameter of 2.5-3 mm. Using this disc, minced meat is obtained for preparing baby food, pates, meat soufflé, as well as fillings for pies and pancakes.
Some meat grinders, often industrial ones, have discs with two or three large holes. Such grates are suitable for finely cutting meat, for example, for preparing beef stroganoff.
If the meat grinder is equipped with only one disc, this is not a reason for frustration. It is easy to select additional grilles, knowing the size and configuration of the mounting hole.
What types of gratings are there?
Our meat grinder grates are perforated steel discs. Based on the diameter of the holes, there are 4 main types of gratings:
- a grid with small holes (about 100-120 pieces per disk) with a diameter of 2 -3.5 mm, these disks are indispensable when preparing “pate-like” products, as well as baby food products. To increase the productivity of this type of grid, we recommend using it for secondary grinding of minced meat prepared earlier using a larger grid;
- a disk with medium-sized holes (about 48 holes with a diameter of 4 - 6 mm). It is considered a universal lattice form, because traditionally used to prepare most types of minced meat;
- gratings with large holes (about 18 holes with a cross-section of 7 - 9 mm). Used for preparing coarse-grained minced meat for the production of sausages, for grinding dried fruits or for preparing intermediate minced meat for the purpose of repeated and easier grinding using a disk with small-diameter holes;
- a disk with particularly large holes (usually 3 to 6 holes with a diameter of 11 - 12 mm). Such grates are used for preparing so-called chopped minced meat.
Advice!
When choosing a grid for a meat grinder, pay attention to the shape and size, since NOT all grids (like knives) are equally universal and may have physical differences.
The grate may have a depression or bulge; these features will tell you whether the grate will fit your meat grinder or not.
Methods for sharpening knives
Knives for household meat grinders, especially stamped ones, need to be sharpened periodically. This must be done immediately, as soon as the productivity of the unit has decreased, the number of strands and films that began to be wound on the auger has increased.

Cutting surfaces are sharpened in special workshops, but you can do it yourself if you have a sharpening tool, the skill to work with it and a little free time.
When sharpening, several methods are used:
- On the grindstone. The stone is generously moistened with water and circular movements are performed first with a knife and then with a disk, pressing the side that comes into contact with the cutter blades to the stone. Movements are made in one direction, evenly pressing the part being sharpened. After finishing sharpening, you need to fold both elements of the cutting block and check for the absence of clearance between them.
- Using sandpaper. The sandpaper is fixed to a piece of plastic or plexiglass with glue and sharpened in a circular motion in one direction. First, use medium-grain paper for sharpening, and then use fine-grain paper for polishing to a mirror finish.
- Using a meat grinder sharpening kit. The set includes two abrasive discs. First, insert a disk instead of the grate and sharpen the cutter, then insert another disk instead of the cutter and sharpen the grate. To sharpen blades, 30-50 shaft revolutions are quite enough.
You can sharpen cutting parts on a special sharpening machine, but only if you have experience and knowledge of basic safety requirements. It is better to take dull knives to a craftsman, and periodically sharpen the cutting parts yourself by hand.
How to sharpen a meat grinder knife?
What to do if the knife is dull and does not want to cut meat? You can sharpen your meat grinder knife yourself
There are a lot of ways: from a machine with a grinding wheel to a file and sandpaper. There is a lot of information about this on the Internet, and we will not dwell on it.
In our article we would like to touch upon several other sides of this issue.
Frankly speaking, sharpening knives for meat grinders is extremely undesirable, even somewhat impractical and unwise.
- Firstly, you need certain skills and experience - otherwise you can only make things worse.
- Secondly, when sharpening the cutting elements of a knife, the blades are not sharpened, but rather ground down! By sharpening the knife, we automatically increase the gap between the grid and the knife, which we wrote about above! Accordingly, we have to return to the point where it is indicated about the unpleasant procedure...
From this we can conclude: if the meat grinder does not turn the meat well, then one of the reasons may be a dull knife. And accordingly, you just need to replace it with a suitable new one.
Advice
!
If your meat grinder begins to turn meat poorly, then it’s time to change the cutting element! And second: not all meat grinder knives are the same and universal. It is very important to know that all knives vary depending on the brand and model of the manufacturer. We also advise you to consider that other parts may need to be replaced.
As we discussed earlier, the knife and the grid are almost always in close contact with each other, which means that the grid can also be subject to wear, so our recommendation is to replace the knife at the same time as the grid. By the way, we have kits for these purposes.

A meat grinder is a very necessary device in the kitchen. Today there are other devices for grinding food, but a meat grinder is a more traditional option and also has simple functionality. The cutting knife is practically the main element of the meat grinder. Unfortunately, in low-quality models this is also the most fragile part.
Types of knives
There are a huge number of models of electric devices for grinding food, and accordingly, the knife for the meat grinder must be suitable. They come in the following types:
- With a 6 corner base.
- With a 4 corner base.
- A base with square sides.
Due to the fact that a meat grinder knife grinds food, the most important work falls on it - the load, which it copes with very well. If the knives begin to become dull, then they should be taken to a service center that matches the model of the meat grinder.
Peculiarities
The meat grinder knife is characterized by different modifications. A popular variety is with four cutting blades. Three- and two-blade cutting parts also exist, but are less common. Knives for an old manual meat grinder differ in the material they are made from. For example, now this part is made of soft stainless steel. Previously, knives were made from high-carbon, durable tool steel.
The main differences between domestic and foreign-made knives are in the appearance of the cutting tip . The cutting edge of a classic knife is in front when viewed relative to the vertical. The cutting process is ensured by sliding, but it is small. This type of knife is not very effective in operation.
Modern electric meat grinder knives are usually saber-shaped. Thanks to the strongly offset cutting edge, good glide is ensured. The efficiency of saber-shaped knives is high. They are widely used for household electric meat grinders.
Meat grinders, which are used in catering establishments, have particularly high productivity. The knives on such units differ significantly from those used in home meat grinders. The profiles of the cutting edges are straight, and the blades themselves have protrusions.
Such profiles provide the same sliding force. The conditions for cutting the product with such a knife provide good efficiency. At the same time, unlike a saber knife, which acts as a spatula, spreading the minced meat in front of the grate, knives for a professional meat grinder precisely chop the product, and in 10-15 minutes.
A knife with saber-shaped points has recently been used less frequently in household meat grinders, as it has the main drawback - it pushes the meat to the edges of the auger. The housing in front of the grate becomes “overgrown” with product, productivity decreases, and the device requires periodic cleaning. When you need to process a limited amount of meat, it is not noticeable. The process becomes difficult with large batches being processed.
It is important to pay attention to the features of the unit’s knives, especially if you plan to process large amounts of meat or other products at home. The optimal power of a home electric unit is considered to be 250-700 W, which allows you to make minced meat from 2-3.5 kg of meat in 1 minute. If it is customary for a family to prepare a fairly large amount of minced meat, you can take a closer look at models from 800 W - they usually have increased functionality.

The configurations of meat grinders are different, but the wider the functionality, the higher the price of the device. If many attachments are not needed in use, it is better to choose a simple model, but with a high-quality cutting element.
Types of meat grinders depending on the types of knives and grates
However, there is another important factor that needs to be taken into account when buying a meat grinder for a professional kitchen - these are meat grinder knives
, or more precisely, the type of cutting tool. The quality of grinding, the level of productivity and the degree of durability of the device depend on it. You should choose one type of mechanism or another depending on the quantity of products produced, the characteristics of the raw materials used, as well as the expected quality of grinding.
All professional devices for chopping meat are divided according to the type of knives into two systems: Enterprise and Unger.
Moreover, the second of them is divided into two more subsystems - semi-Unger (or Unger 3) and full Unger (Unger 5). The most well-known to a wide range of consumers is the Enterprise system, used in the production of not only industrial, but also household devices for preparing minced meat. When choosing a meat grinder for processing veined meat, it is recommended to pay attention to devices with a power of at least 600 W. To ensure that the machine's knives become dull as rarely as possible, they must be made of high-quality steel. The optimal solution is to choose knives with saber sharpening.
Types and forms
These parameters are closely related to the type of meat grinder. Popular manufacturers of meat grinders include Bosch, Moulinex, Philips, Zelmer, Kenwood, Redmond, and Polaris. Manual and electric models have no other fundamental differences, except that the latter are characterized by greater power. They can successfully process even frozen meat with streaks. In addition, using the device you can get not only classic minced meat, but also a version chopped into small pieces.
The German manufacturer Bosch collects the largest number of positive reviews. The models, although not the most powerful, are distinguished by high-quality assembly and durable components. Zelmer is the second most popular manufacturer, supplying high-quality equipment with inexpensive components. The more popular a particular type of equipment is, the easier it is to select components in the future. They are often interchangeable and inexpensive.
For example, the listed types of meat grinders work according to an identical scheme, the main components are made of the same material - stainless steel, the body of the electrical device is plastic, there is the necessary minimum of additional attachments that are used for preparing sausages and other delicacies. Despite the simplicity of the device, today there are many manufacturers, so there are a large number of types and forms of accessories.
In addition to the blades, the knives have a different base configuration. The most commonly found elements are:
Due to the difference in base shapes, it can be difficult to select an element for a specific meat grinder model. In addition, some manufacturers produce different types of knives for different series of meat grinders. Thus, the popular brand Moulinex is found with a hexagon and square base. Zelmer only offers components with a square seat. Bosch, Braun, Kenwood, Gorenje are also made with a square base.
The blade shapes differ between varieties, but this only plays a role in processing efficiency. The problem can only arise if a large amount of meat is processed. Blades are single-sided and double-sided. The latest models are easier to operate, since they can be inserted from either side. With the first type, difficulties arise for inexperienced housewives. In this option, the flat side of the knife must touch the grid, which is installed behind the disk. The convex side should be on the auger.
Over time, meat grinder knives become dull. The elements do not have a self-sharpening function, but the steel of ordinary cutting elements can be sharpened at home. A meat grinder knife can be sharpened with sandpaper, the main thing is to address the problem in a timely manner.
A self-sharpening knife is included in the Moulinex ME 6201, Kenwood MG-700, Bosch MFW 68660 kits. The price of the devices ranges from 6,500 to 18,000 rubles.
A separate type of cutting elements can include two-bladed scoring knives, which are included in the set of old-style professional meat grinders. The element is installed in MIM-300, MIM-300M, M-250 (UKM), TM-32, TM-32M and others, with the diameter of the parts used being 82 mm. Such an element has holes, and at the entrance they are narrower than at the exit. This is necessary so that the processed product comes out more easily.
If you place the wide side from the entrance and the narrow side towards the exit, then there will be some compression of the product. In enterprises, such a knife is used for processing dough products, such as pasta.
Rules for the maintenance and operation of knives for meat grinders
To extend the life of your Eurokitchen knife you need to follow a few simple rules:
The knife should be washed with detergent immediately after use.
Do not leave cutting elements in water for a long time.
After washing the knife and grate, wipe them dry.
Do not grind hard foods (frozen meat, bones, etc.) in a meat grinder.
Store meat grinder knives separately from cutlery, as the cutting edges quickly become dull due to contact with metal.
