Features

Bridge gantry machining center is a high-precision, high-efficiency, high-stability, easy-to-operate machining equipment with a high degree of automation and multi-functionality to meet the needs of different types, sizes and complexity of parts processing.

•  

  Modular gears with two-speed + spindle direct-connected design or built-in spindle design provide different cutting characteristics to meet diversified machining needs.
• 2,500kg/m2 heavy-duty stationary table meets various machining requirements for heavy workpieces.
• Floor-mounted tool magazine is located at the back of the machine for quick tool change and easy operation and maintenance.
• Large separated water tank and spiral chip conveyor on both sides of the table facilitate maintenance, improve chip removal efficiency and ensure cooling performance.
• The overhead bridge structure design provides excellent and stable dynamic accuracy, and at the same time, the footprint is reduced by more than 40% compared with the fixed-column model.
• The main body of the machine is a cross-rail bridge structure, so that the machine can provide the same dynamic characteristics when carrying different workpiece weights, high rigidity of the machine, and reduce the footprint, high space utilization. The internal design of the crossbeam has a fine-tuning structure to make up for the sagging and twisting of the middle part of the crossbeam caused by the self-weight of the headstock.
• The spindle constant power range is wide, and the spindle bearing adopts high-precision, high-rotation speed and high rigidity bearings, so that the spindle operates with high precision, low noise, low vibration and low thermal deformation, and the spindle head has high output torque and high cutting torque.The X, Y and Z coordinate axes adopt AC servo motors and heavy-duty linear rolling guideway sub, which have strong load bearing and anti-distortion ability, small friction coefficient, fast response speed and good stability, and can realize high-speed and high-precision Positioning.
• Intelligent automatic compensation of gravity effect in the Z-axis counterweight system closed loop design, can quickly compensate for the gravity effect generated by the movement, and can minimize the motor load.
• Equipped with intelligent non-contact tool setting instrument, using NC4 automatic tool setting allows the machine tool to have the intelligent management ability of self-judgment and decision-making, thus realizing unattended fully automated machining. Reduced scrap rate, high flexibility and reliable operation.

Applications

• Bridge gantry machining centers are mainly used for multi-species machining of complex parts in the aerospace industry. It occupies a large advantage in the production and processing of aluminum components. The workpiece can be clamped once to complete the five-face machining and multi-space milling and drilling of multiple processes with high efficiency and high precision.
• It is widely used in aviation, aerospace, automotive, mold and other industries.
