Day by day development is humanity’s continuing to create conveniences for itself. Since the 80s of the last century, when cutting iron or hard objects was a problem, abrasive discs became the solution to this problem. Abrasive cutting discs are mainly produced according to the following body types.

  • Wood
  • Metal
  • Bricks
  • Concrete
  • Marble-Granite

We will try to explain in detail the necessary raw materials and technologies for the production of metal cutting abrasive discs, which are mainly useful for the customers of AFEX GROUP. Metal cutting abrasive discs are mainly imported from Russia and China. You can reduce the amount of imports by producing this product.

The fact that the production process of this product is not complicated, it is suitable for both new businessmen and experienced entrepreneurs.


The photo above shows a disc marked according to state standards for cutting metal. The areas of the disk are marked with numbers, these numbers mean:

  1. Constructive type (ISO 41, flat).
  2. Geometric characteristics – diameter, thickness, hole.
  3. Physical characteristics: abrasive type (A – electrocordum); grain size; degree of hardness (Latin T – very hard); type of connection (BF – reinforced bakelite).
  4. Maximum rotation speed.
  5. Maximum peripheral speed allowed.
  6. For which material it is intended.
  7. Security icons.
  8. Reference to regulatory documents.
  9. Manufacturer’s logo.

The production of the flat type of cutting discs on this line is calculated in the total amount. If you want to produce the depressed type as well, you are required to purchase these product molds.


It uses cutting discs of the necessary sizes for various Bulgarians. We have also selected technologies that produce metal cutting discs that are widely used.

  1. Outer diameter: 100,115,125,150,180,230 mm;
  2. Diameter of the central ring: 22.32 mm;
  3. Thickness: 1.0, 1.2, 1.6, 1.8, 2.0, 2.5, 3.2 mm


  1. Abrasive particles.
  2. Resin powder.
  3. Cryolite.
  4. Gypsum powder.
  5. Black carbon.
  6. Fiberglass mesh.
  7. Special black paper (for the bottom part).
  8. Colored aluminum oxide (on the surface).
  9. Metal folk.


In our country, you can find abrasive discs that are mainly imported. The purchase of the product depends on the level of quality. The simplicity of product production increases the possibility of substituting imported products. The fact that the product becomes useless during the cutting process ensures the sustainability of sales.


The area required for this line should not be less than 150m/sq. If there is an opportunity for light trucks to enter or take out raw materials and finished products, it will increase the productivity.

•Required transformer-above 160KW/380V, 50HZ.

• For 1 ton of product – 300 KW energy consumption.

• The number of workers requires 8-10 people.



•Equipment for cutting glass fiber nets.

•Metal folk making equipment.

•Vibrating sieve.

•Two bowl hydraulic mixer.

•Abrasive disc preparation equipment (100,115,125 mm).

•Abrasive disc preparation equipment (150,180,230 mm).

•Special electric oven.

•Balance checking equipment.

• Testing equipment.

•Air compressor.

We learned about the necessary information about the product and the production mechanism in detail. Now let’s get acquainted with the equipment of the line.
