Gear wheels
Bevel and cylindrical gear wheels
In our company, we are constantly expanding our offer. In addition to mining machinery and gearboxes production, we also manufacture gear wheels with internal or external toothing. The most modern equipment is used in the production process, including milling, grinding and slotting machines. With the use of specialized and diversified equipment, we can offer cylindrical and bevel gear wheels of the highest quality.
