Product Description

GM4028R  Production Description
1. Machine tool performance:
GM4028R is a heavy-duty cutting machine tool, which mainly processes large and medium-sized castings and welded parts. It is suitable for parts processing in the aerospace, energy, engineering machinery, machine tools, vehicles and other industries. It has the characteristics of high precision, high efficiency, flexibility and environmental protection. Its performance indicators and accuracy indicators meet the relevant national standards.
2. Overall machine structure characteristics:
The worktable is movable, the gantry is fixed, the Z axis is a fully enclosed square slide, and the X and Y axes use heavy-duty linear rails.
3. Main transmission structure characteristics:
The main motor is arranged at the top of the slide, and an imported reduction gearbox is selected. The reduction gearbox and the spindle are equipped with an oil cooling system.
4. Feed structure characteristics:
The X, Y and Z axes are all driven by high-precision ball screws and equipped with imported reduction gearboxes. The Z axis is equipped with a nitrogen balance device.
5. Operating system:
Two high-performance CNC systems are available: FANUC 0i-MF(1) and SIEMENS 828D.
6. Optional configuration:
Tool magazine, right-angle milling head, extended milling head, extended right-angle milling head, universal milling head, etc.
7. Manufacturing specifications:
The quality of all machine tool parts and components processed and assembled shall comply with the product drawings and relevant technical requirements, and its safety standards shall comply with the relevant provisions of GB15760-2004 "General Technical Conditions for Safety Protection of Metal Cutting Machine Tools", and its accuracy standards shall comply with the relevant provisions of GB/T17421-2000 "General Rules for Machine Tool Inspection" and GB/T19362.1-2003 "Inspection Conditions for Gantry Milling Machines".
