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.
Existen garantías ampliadas, con coberturas que van de 1 a 3 años. Estos planes se personalizan en función del tipo de equipo, la frecuencia de uso y las necesidades del cliente. Una ampliación de un año para un solo dispositivo cuesta aproximadamente 3%-5% del precio total, mientras que las ampliaciones masivas para varios dispositivos o líneas de producción totalmente automatizadas ofrecen un descuento de 20%. Durante el periodo de ampliación de la garantía, además de las reparaciones de los componentes principales, los clientes también reciben un servicio anual gratuito de inspección y mantenimiento integral de los equipos para ayudarles a identificar proactivamente posibles fallos y prolongar la vida útil de sus equipos.
Tanto si está actualizando una línea existente como si está iniciando un nuevo proyecto, STON personalizará una solución CNC para su producción.
