In the world of power transmission, producing a gear isn’t enough — absolute precision is the real goal. That’s where involute grinding comes into play: one of the most critical and refined stages of the gear manufacturing process. At Cattini, this phase is not just a final touch — it’s a strategic operation that ensures smoothness, durability, and efficiency.
What is involute grinding?
Involute grinding is a high-precision machining process used to perfect the profile of gear teeth, removing micro-imperfections and bringing the component within extremely tight tolerances — often within just a few microns. It directly impacts how a tooth comes into contact with its mating gear, influencing load transmission, noise, heat generation, and long-term wear.
Cattini’s grinding technology
Cattini uses advanced CNC gear grinding machines, engineered to deliver precision even across high-volume production. But the real added value lies in the company’s integrated approach. Each gear is processed according to its material, geometry, and final application — from compact automotive systems to large industrial reducers.
Highly skilled technicians monitor every step, inspecting tooth depth, contact lines, and profile deviation with meticulous care. The result? Gears that deliver smooth rotation, zero vibration, and consistent performance, even after thousands of operational cycles.
Real-world advantages for customers
A gear ground with Cattini’s involute technology offers:
-
Up to 30% noise reduction compared to non-ground gears;
-
Improved mechanical efficiency, thanks to smoother and more even contact between teeth;
-
Less wear on connected components, such as bearings and shafts;
-
Greater dimensional stability even after thermal cycles or dynamic loads.
These benefits are especially critical in sectors like high-end automotive, precision tooling, and wind energy, where every decibel, every watt, and every micron matters.
Quality that becomes a competitive edge
At Cattini, excellence isn’t just a slogan — it’s a technical and strategic investment. By committing to processes like involute grinding, the company ensures longer-lasting components, more reliable systems, and more competitive customers.
In an industry where expectations are constantly rising — in terms of performance, efficiency, and sustainability — a perfectly ground gear can be the difference between functioning… and excelling.
