1、 Main features of the machine
1Scope of application of the machine:
Grm-500HT卧The type machining center machine integrates advanced technology and advanced manufacturing technology, and is one of the high rigidity horizontal machining centers launched by Grema CNC Technology. It meets the extremely demanding metal processing conditions in today's market and is suitable for various mechanical processing fields such as automotive, aerospace, military, and hardware.
2Overall layout of the machine tool
The overall layout of the machine tool adopts the classic inverted designThe T-shaped dynamic column structure and the overall bed structure have high rigidity and good stability.
3Structural characteristics of machine tools
The main components of this machine tool consist of a base, an indexing worktable, a moving column, a spindle box, and an automatic tool changing system. The main components are made of high-strength and high-quality cast iron, and residual stress is eliminated through a complete heat treatment process. Sufficient reinforcing ribs are arranged to ensure that the entire machine has sufficient strength, rigidity, and high stability;
3.1base structure
The special ultra wide base with uniform mechanical distribution can not only improve the support capacity as stable as Mount Tai, but also greatly improve the shock absorption capacity. This has laid a solid foundation for the high precision and stability of the entire machine.
3.3Workbench structure
The workbench adopts a toothed disc positioning structure with high positioning accuracy; Continuous division can also be optionally selected（A CNC worktable positioned at 0.001 °.
3.4Dynamic column structure
The special door shaped dynamic column design increases cutting rigidity and can maintain stable accuracy for a long time, ensuring the stability of the machine.
3.5Spindle box structure
The spindle head adopts a reinforced structural design to enhance cutting rigidity. Can be matched with different spindle structures, including direct spindle structure, belt spindle, and gearbox structure, to meet the needs of various industries.
3.6Automatic tool changing system
Paired with knife arm style40TKnife storage, shortcut knife selection, fast tool changing speed.
