The GM-SB-38CNC-2A-1S is a fully automatic, CNC-controlled pipe bending machine designed for precision manufacturing. This equipment is manufactured by several Chinese companies, including GMACC, SANCO Group, and ZHANGJIAGANG KING-MACC MACHINERY MANUFACTURING CO., LTD., and is marketed for industrial use in workshops and factories. The machine is characterised by its ability to handle pipes and tubes with a maximum diameter of 38 millimetres, making it suitable for a range of applications involving metal, aluminium, or steel. Key features include a CNC control system for automated operations, a hydraulic system for force and precision, and a compact design. The machine is CE certified, indicating compliance with European health, safety, and environmental protection standards.
Technical Specifications and Design
The GM-SB-38CNC-2A-1S is engineered with a robust construction. The machine body is fabricated from ultra-thick Q235 welded steel plate, which undergoes tempering and strict quality control to eliminate internal stress and ensure strength, stiffness, and longevity. This design principle combines European reliability with Asian manufacturing efficiency. The mechanical parts are assembled using an imported hydraulic system and electronic controls. The hydraulic system, a critical component for the bending operation, is primarily sourced from imported brands and includes cooling and speed adjustment devices for stable and durable performance. The electrical parts, including the cabinet which conforms to IP65 standards, are supplied by Schneider of France, ensuring strong performance and good stability. The machine's overall design aims to provide high precision, speed, durability, and security.
Control System and Operation
The operational core of the GM-SB-38CNC-2A-1S is its advanced control system, which allows for manual, semi-automatic, or fully automatic operation. The machine employs a PLC (Programmable Logic Controller) control system, often equipped with a Mitsubishi servo system. This includes servo drivers, motors, a positioning module, and a CPU, which accurately control multiple axes. The bending arm, for instance, is controlled by a servo motor and gear, enabling high bending accuracy.
Operation is facilitated through a VDU (Visual Display Unit) touch screen operating panel or an industrial computer with a touch-sensitive interface. This interface integrates colour and three-dimensional display software, making the machine user-friendly. Operators can input bending data and orders directly, with the capability to enter X, Y, Z coordinate values or Y, B, C process values. The system includes power and memory functions, allowing for the storage of up to 200 working programmes. This large memory capacity enables the rapid programming of complex shapes and the storage of various bending sequences. The machine also features an automated bending calculation function for angles, reducing the likelihood of errors and saving time and resources during manufacturing.
Key Features and Safety
Safety is a significant aspect of the GM-SB-38CNC-2A-1S. It includes crisis end buttons as emergency stop mechanisms. The machine's CE certification is a testament to its compliance with stringent European safety standards. Furthermore, the electrical cabinet's IP65 rating ensures protection against dust and water ingress, which is crucial in industrial environments. The machine is designed to handle a maximum bending radius of 200mm and is capable of producing elbow bends in a clockwise direction. A cooling water circulation pipe is also part of the equipment, aiding in temperature management during operation.
Manufacturer and Market Position
Several manufacturers produce this model, each highlighting specific strengths. GMACC markets the machine as an "Economic pipe Bending Machine," emphasising its cost-effectiveness and suitability for enhancing factory efficiency. SANCO Group, a company with 176 workers and 11 professional engineers, occupies a significant position in the Chinese market. SANCO is noted as the leader in drafting the "Chinese Standard of CNC Pipe Bending Machine" (GB/T28763-2012) and the "Chinese Standard of Pipe Bending Machine Safety" (GB28760-2012). All their machines are marked with IS9001:2000 and CE certifications. ZHANGJIAGANG KING-MACC MACHINERY MANUFACTURING CO., LTD., which built the machine in 2022, positions the GM-SB-38CNC-2A1S as a perfect solution for any production facility requiring precision bending of bars, profiles, and tubes.
The machine is available for purchase from various suppliers, with a typical minimum order quantity (MOQ) of one piece. For example, SANCO Group lists the machine at a price of US$14,500.00 per piece.
