How abrasive wheels are made: Stark Abrasive production
Abrasive wheels are the foundation of high-quality grinding and surface finishing.
Their performance, durability, and safety depend directly on how they are made.
Stark Abrasive produces abrasive materials that meet international quality standards and deliver consistent results.
Selecting the abrasive grain
The first stage of manufacturing is the selection of abrasive grains, which define the wheel’s hardness and purpose.
Materials such as aluminum oxide, silicon carbide, or zirconia are commonly used.
These components offer excellent strength and resistance to heat and wear.
Bonding materials
Next comes the addition of bonding agents — resin or ceramic compounds.
They hold the grains together and maintain the wheel’s structure during operation.
The type of bond determines how fast the wheel wears and what surface finish it produces.
Forming and sintering
After mixing, the abrasive blend is pressed into molds to create wheels of the desired diameter.
Then the wheels undergo thermal treatment (sintering) to achieve strength and stability.
Every parameter — density, geometry, and uniformity — is carefully controlled during this stage.
Balancing and quality control
Before packaging, each wheel goes through dynamic balancing.
This ensures smooth operation at high speeds and reduces vibration during grinding.
Finally, the product is marked, tested, and prepared for shipment to customers.

3M™ Flap Disc 769F – is our durable, high-performance abrasive flap disc with precision-shaped grains from 3M™ Precision-Shaped Grain and durable polyester base.
3M™ Flap Disc 769F – convenient, strong, efficient and universal petal disc. Our discs are coated with 3M™ Precision-Shaped and proven to be more effective than traditional zirconium corundum petal discs. This abrasive is constantly breaking down to form sharp particles that cleanly cut metal, unlike traditional abrasives that tend to plow through the substrate. This breaking down into particles, together with the destruction of individual petals to release fresh layers of mineral, ensures a high grinding speed that is stable throughout the life of the disc. Polyester base additionally extends durability. Together with the high adhesion, this makes the discs an ideal choice for high-pressure jobs such as beveling, grinding welds and deburring edges. In addition, they create clean surfaces, which makes them indispensable for smoothing and surface preparation. In many cases, 3M™ Flap Disc 769F provides sanding and finishing without changing the abrasive tool. This is possible because under normal conditions the 769F disc finish is one step thinner than a fiber disc of the same grade. Although the fiber disc grinds faster, this petal disc simplifies the process flow, eliminating the need to change tools, which saves time and increases productivity. An ideal choice for processing carbon steel, stainless steel and other alloys sensitive to high temperatures.
3M petal discs™ Cubitron™ II 967A are designed for grinding and finishing in one step and perform a larger amount of work in the same time. The exceptional capabilities of the precision-shaped ceramic grain of 3M™ in petal grinding discs. Petal grinding discs 3M™ Cubitron™ II work faster and require less pressure, helping to reduce operator stress on the most difficult operations, including grinding operations, weld removal, deburring and more.
The secret to high efficiency flap discs 3M™ Cubitron™ II 967A consists of 3M™ precision shaped ceramic grain. Triangular grains are oriented perpendicular to the base, act as cutters, easily cutting through metal, and are constantly self-sharpening as the microparticles are chipped during the grinding process. As a result, Cubitron™ II 967A grinds quickly and without overheating and continues to work after ordinary discs have exhausted their resource and need to be replaced.
Cubitron ™ II 982C are used for cleaning welds, grinding and finishing the surface
Thanks to its flexible design and the special shape of the mandrels, the fiber discs fit a larger area to the processed surface, which allows you to preserve the "flatness" surface.
