GM4022 3/4/5 Axis Gantry Milling Machine Top Precision CNC Lathe and CNC Machining Center Factory Direct

Product Description

GM4022 Production Description
GM4022 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 concept in the world. It is suitable for machining various large workpieces in industries such as aerospace, shipbuilding, power generation, heavy machinery, locomotives, machine tools, textile machinery, printing machinery, and automobile cover molds.
The high-strength, high-rigidity design and large-flow chip removal channel structure of this machine tool have the characteristics of high precision, high efficiency, flexibility, and environmental protection. Its performance indicators and precision indicators meet relevant national standards.
The whole machine adopts a moving table gantry structure. The bed is fixed, and the workbench moves in the X direction on the bed; the ram moves in the Z direction on the slide; the slide together with the ram moves in the Y direction on the gantry beam; the X and Y axes use heavy-load linear rails, and the Z axis is a plastic-coated hard rail. The spindle assembly is placed at the lower end of the ram; the whole machine has a reasonable layout, beautiful appearance, and easy operation.
Spindle: It adopts a high-speed spindle unit, and the spindle adopts BT50 specifications.
Tool magazine: The tool magazine adopts a disc-type tool magazine with reliable quality and stable performance. (Optional)
Drive: The three-axis motor and high-precision ball screw adopt direct drive. The ball screw is pre-stretched and installed to improve the transmission rigidity and positioning accuracy.
The quality of the finished products of all machine tool parts and components is in line with the product drawings and relevant technical requirements. Its safety standards comply with the relevant provisions of GB15760-2004 "General Technical Conditions for Safety Protection of Metal Cutting Machine Tools", and its accuracy standards comply with the relevant provisions of GB/T17421-2000 "General Rules for Machine Tool Inspection" and GB/T19362.1-2003 "Gantry Milling Machine Inspection Conditions".
