High Performance Gantry Milling and Drilling Machine CNC Machining Center

Product Description

1. Machine technical description
GDGM-3025NC is a fixed beam and fixed column gantry machining center machine tool. It is developed based on the most popular, advanced and flexible machine tool design concepts in the world. It is suitable for aerospace, shipbuilding, power generation, heavy machinery, locomotives, machine tools, and textile machinery. , Printing machinery, automotive covering molds and other industries of various large-scale workpiece machining equipment.
The machine tool's high-strength, high-rigidity design and large-flow chip removal channel structure have the characteristics of high precision, high efficiency, flexibility, and environmental protection.
The machine adopts the gantry structure of moving table. The bed is fixed, the worktable moves in the X direction on the bed; the ram moves in the Z direction on the sliding seat; the sliding seat and the ram move in the Y direction on the gantry beam; the X and Y axes adopt heavy-duty linear rails, Z The shaft is a plastic hard rail. The main shaft assembly is placed at the lower end of the ram; the whole machine has a reasonable layout, beautiful appearance and convenient operation.
Spindle box: We use high-speed BT50 spindle unit with center blowing.
Tool Magazine: We use disc magazine with high quality and stable functionality.
Transmission: The three-axis motor and high-precision ball screw adopt a direct drive method. The ball screw is pre-tensioned and installed to improve transmission rigidity and positioning accuracy.

Note:Desihn & Specifications are subject to change without prior notice.
The quality of the finished product processing and assembly of all parts of the machine tool conforms to the product drawings and related technical requirements, and its safety standards comply with the relevant provisions of GB15760-2004 "General Technical Requirements for Safety Protection of Metal Cutting Machine Tools", and its accuracy standards comply with GB/T17421-2000 "Machine Tool Inspection General Rules" and JB/T8771-1998 "Machining Center Inspection Conditions" relevant regulations.
3. General requirements
Required environment
Keep the temperature at a balanced level, especially during precise cutting.
Working temperature10ºC~40ºC, when 20ºC, humidity should be around: 40~75%
To keep the static accuracy of the machine within the specified range, the best temperature is within 15ºC~25ºC, and the temperature difference should not exceed ±2ºC/24h.
Power supply voltage: 3-phase, 380V, voltage fluctuation within ±10%, power supply frequency: 50HZ.
If the voltage in the area is unstable, the machine should be equipped with a regulated power supply to ensure the normal operation of the machine tool.
The machine should have a reliable grounding: the grounding wire should be copper wire, the wire diameter should not be less than 10mm², and the grounding resistance should be less than 4 ohms.
In order to ensure the normal working performance of the machine, if the compressed air of the air source does not meet the requirements, a set of air source purification devices (dehumidification, degreasing, filtration) should be in placed before the machine's air intake.
Keep the machine away from direct sunlight, intense vibration, high heat, high-frequency generators and electric welding machines, etc., to avoid machine production failure or loss of machine tool accuracy.
