I. Application Fields
The DGM series gantry machining centers are fixed-gantry gantry machining centers developed and produced by Dalian Machine Tool. They are widely used for the processing of box-type components and complex-shaped components in industries such as automotive, metallurgy, mining, and machine tool manufacturing. This machine tool boasts features such as efficiency, high precision, high rigidity, and high flexibility, making it an ideal equipment for enterprises to enhance work efficiency and improve the efficiency of flexible component processing. It is a perfect choice for processing medium to small batch quantities of parts.
Two,Machine Tool Features and Key Technical Indices
1. Machine Tool Features
（1）FANUC 0I MF (1) CNC control system (optional SIEMENS 828D)
(2) Utilizes a movable workbench structure with the bed, column, and beam fixed, featuring strong rigidity and smooth movement.
(3) High-strength cast iron frame structure (including bed body, worktable, uprights, beams, sliding saddle, and sliding pillow, etc.)
(4) The main shaft features a ZF two-speed transmission plus a direct-drive main shaft structure, capable of meeting various customer demands for high rotation speeds or high torques.
(5) The main shaft and main shaft transmission are cooled by a constant-temperature cooling unit.
(6) Machine tool tool magazine (optional) with 24 disk-type manipulators or 40 chain-type structure magazines
(7) The X and Y motion coordinate axes use linear rolling guideways, offering high response speed; the Z axis employs sliding guideways.The pillow block bearings offer high rigidity.X-2100mm, Y-1620mm (including 220mm tool change travel), Z-800mm.
(8) All three axes utilize high-precision ball screws (X-axis φ63 mm)，Y-φ50 mm，Z-φ50 mm）；
(9) The X-axis drive is equipped with a servo motor that is directly coupled to the ball screw via a reducer, while the Y and Z-axis drives are directly coupled to the ball screw with servo motors.
(10) Fast Travel Speed (X - 24 m/min, Y - 24 m/min, Z - 16 m/min)
(11) Complete Machine Protection
(12) Spiral chip conveyors (optional chain conveyors) and chip elevators with automatic chip removal (dry type) (optional with wet processing configuration with water tank)
2Key Technical Indicators
（1）Spindle featuresZFTwo-speed transmission+Directly connected shaft structure, guaranteed.High and low-speed machining performance of machine tools; high-speed machining
(2) Utilizes advanced high-precision large-diameter ball screw transmission to ensure transmission stability and enhance machining accuracy of the machine tool.
(3) The spindle is equipped with a temperature rise control device, reducing the temperature rise fluctuations during spindle processing to ensure the machining accuracy of the machine tool.
(4) The rapid movement speed of the machine tool at 24/24/16 m/min shortens processing time and improves processing efficiency.
(5) Machine tools equipped with a coordinated tool-changer (tool change time: 5 seconds)
(6) The main components of the bed frame are all castings, which have been optimized through finite element analysis during the design process to achieve a more rational structure.
(7) Utilizing a highly reliable FANUC 0I MF (1) CNC system
