Gears

Thanks to many years of know-how from our area, the qualified staff and our modern machinery, we are in position to realize your projects. We offer a complete machining. Our machines are perfect for precision gear cutting, whether it be a standard or custom design, small and large diameter gears of various dimensions and complexity.

What we understand by complete machining? The large machine park, in which constant investment was made, and the qualified employees guarantee the highest processing results. With Nova Gears you will get everything from one source: turning, milling, gear cutting, heat treatment, grinding, gear grinding. In our production facilities with modern CNC machines, our highly qualified production team produces gears in various sizes. They are made especially of steel, with varying levels of case hardened and annealed (up to 62-64 HRC).
