Sigma: Innovation and Performance in Leather Grinding
The leather processing industry requires continuous innovation to maintain high quality standards. Thus was born Sigma, the new roller buffing machine that embodies all the improvements requested by customers. Produced with cutting-edge technologies, Sigma stands out from traditional models for a series of technical features that increase its efficiency, precision and ease of use.
Let’s take a look at the features that make Sigma a leading machine in the market.
A new frame for greater strength
The Sigma is designed with an innovative frame that is significantly more robust than previous models. The reduction in welds not only strengthens the machine’s overall structure but also contributes to greater durability and resistance to operational stresses.
Vibration-free precision
One of the most common problems with traditional buffing machines is vibration, which can compromise the quality of the work. Thanks to its extremely stable construction, Sigma virtually eliminates this problem, ensuring unrivalled precision in leatherworking.
Powerful and responsive engines
The new Sigma buffing macchine is equipped with upgraded motors, which offer not only greater power but also superior control during operation. This feature makes it easy to handle even the most complex jobs, improving productivity and the quality of the finished product.
Enhanced transmission system
To support the new engines, Sigma is equipped with an upgraded transmission system. This upgrade ensures efficient and smooth power transmission, minimising the risk of breakdowns and extending the machine’s service life.
Increased sealing roller
Another significant innovation is the larger sealing roller, which makes it easier to feed the leather. This feature simplifies the process, reducing the time needed to prepare the material and boosting overall productivity.
Full opening of the front panel
Maintenance is crucial to ensuring the continuous operation of machinery. Sigma offers a system that allows the front panel to be fully opened using a pneumatic mechanism, which improves access for maintenance and reduces machine downtime. This results in greater efficiency and lower operating costs.
Simplified replacement of the feed roller
Maintenance is made even easier by the simple process of replacing the feed roller. This clever design allows maintenance tasks to be carried out smoothly and safely, minimising downtime.
Modified upper cover
Sigma’s upper cover has been structurally modified to ensure smoother and more durable opening. This modification not only makes maintenance easier, but also helps to keep the machine in optimal condition for longer.
Safety and operational efficiency
One of Sigma’s most significant innovations is the movement of the feed roller assembly, which shifts to allow the leather to be retrieved in complete safety, rather than opening the entire table as in traditional models. This feature not only improves operator safety but also makes the production process more efficient.
Integrated B•OS operating system
Equipped with the B•OS operating system, the Sigma buffing machine comes as standard with ‘Industry 4.0’ functionality, which enables network connectivity, the collection of energy consumption data by batch or over a preset time period, scheduled and preventive maintenance, processing recipes, and much more.
Sigma represents a breakthrough in the world of roller sanders. With its advanced features and numerous improvements over traditional models, this machine is destined to become a reference point for companies in the sector. Sigma is not just a buffing machine; it is a promise of quality, efficiency and innovation for the future of leather processing.
