Our machines are engineered to handle a wide variety of materials, including carbon steel, stainless steel, aluminum, copper, and galvanized sheets. The specific thickness and grade depend on the machine’s tonnage and configuration, but our solutions cover the most common industrial requirements.
A CNC system provides precise, repeatable control over the bending angle, back gauge position, and bending sequence. This eliminates the variability associated with manual operation, ensuring every part is produced to the exact same specifications with tolerances as tight as ±0.1 degrees.
While both are types of sheet metal bending machines, a press brake typically forms bends sequentially using a punch and die. A panel bender, like the one shown, uses a more automated process with upper and lower bending blades to form flanges, often without flipping the sheet. Panel benders excel at high-speed production of complex parts like panels, doors, and cabinets.
Our machines are equipped with intuitive, graphical CNC interfaces designed to simplify programming and operation. While a basic understanding of sheet metal principles is beneficial, operators can typically become proficient in running the machine and performing setups within a few days of training.
Absolutely. Our machines are designed with automation in mind. They feature open communication protocols and can be integrated with robotic loading/unloading systems, conveyors, and central factory management software to create a fully automated and highly efficient production cell.
Extended warranties are available, with coverage ranging from 1 to 3 years. These plans are customized based on the equipment type, frequency of use, and customer needs. A one-year extension for a single device costs approximately 3%-5% of the total price, while bulk extensions for multiple devices or fully automated production lines offer a 20% discount. During the extended warranty period, in addition to core component repairs, customers also receive a free annual comprehensive equipment inspection and maintenance service to help them proactively identify potential faults and extend the life of their equipment.
Whether you're upgrading an existing line or starting a new project, STON will customize a CNC solution for your production.
