1. Z direction tutor rail is installed horizontally, 4 sliders can evenly share the weight of the sliding saddle and cutting force, reduce the wear and tear of the balls of the slider, and prolong the service life of the guide rail.
2. high bottom flat guideway slant bed is in consistent state during processing, assembly and use, which can effectively guarantee the precision of machine tool.
3. The main body castings are all cast with high quality cast iron technology. Adopting advanced finite element analysis technology, the design structure is reasonable and the layout is optimised. And by the second aging treatment, can ensure the long-term machining stability of the machine tool.
4. Both axes screws adopt precision ball screws, with scientific pre-stretching assembly process, small thermal deformation and high transmission accuracy.
5. The screw support adopts precision bearings of well-known brands, and the screw locking nut adopts high-precision locking nut, which improves the support and locking precision of the screw and further improves the machining precision of the machine tool.
6. Adopting automatic centralised lubrication system to lubricate the screw, guideway and other moving parts through the set oiling interval and oiling duration to ensure the normal use of machine tool precision and service life.
