Gear tooth profiles up to 3,000 mm in diameter

Gear tooth profiles up to 3,000 mm in diameter

Continual technological updates play a fundamental role for the company. Fabrizio Cesana confirms that every year sees the integration of new machine tools and additional accessories in various departments, either to complement or expand possible processes or to replace older models with more advanced and efficient ones.

“Among the recent acquisitions,” notes Cesana, “is a new hobbing machine, a CNC-controlled device capable of working on gears with diameters up to 3,000 mm.”

This machine, supplied by C.L.C. from Cadelbosco Sopra (RE), joins a diverse set of equipment, enabling Ceba to produce tooth profiles ranging from module 1 to module 30, with diameters between 10 and 3,000 mm. The company can also grind elements with a diameter of up to 2,200 mm, always within module 30, utilizing shape grinding.

“As with other machines we have acquired over time,” Cesana adds, “the new hobbing machine has been developed to our precise specifications, optimizing time and process methods in line with our needs.”

The reason for this new addition is the consistent demand for gears with ever-larger diameters, coupled with positive signals from sectors that were, until recently, struggling, such as machine tools and, particularly, sheet metal processing. This necessitates an increase in production capacity.

“Production capacity,” emphasizes Cesana, “will soon be further augmented with the integration of other new machines, confirming our constant and continuous investments in technology and innovation, to which we have always dedicated attention and resources.”

In addition to the operational hobbing machine of 3,000 mm, Ceba has already planned to start up, by next September, another hobbing machine (for diameters up to 1,500 mm) and a new grinder for working on elements up to 2,000 mm in diameter.

“Expanding our machinery portfolio,” continues Cesana, “will allow for greater flexibility, especially in the automotive sector, which has shown signs of interesting recovery for some time. This is in addition to the ever-active sector of packaging plant manufacturers, paper mills, and wind energy. Unfortunately, the latter doesn’t refer to the Italian market but rather to foreign markets, where we engage both directly with our clients and indirectly through supplies.”

Ceba Gears exports approximately 30% of its turnover, not only within Europe but also in Asia (with a predominant focus on India and Iran) and North Africa. “Recently, Saudi Arabia has given us great satisfaction,” adds Cesana, “thanks to an order for a considerable number of spare gears for some steelworks. This order is expected to be repeated, and we’ll be even more prepared with the appropriate production enhancement.”
