1. Adapt to small and medium-sized, high-precision parts milling external square, two, four, six, eight square, etc..

2. Adopting numerical control system, it can realise curved surface, curved surface and taper surface machining.

3. operation mode manual, semi-automatic can be built: can be added with feeding device to achieve fully automatic production, saving manpower.

4. Change the traditional milling square machining process, which can improve the efficiency by 2-5 times, and the product surface finish is high.

5. The main body castings are all made of high quality cast iron. 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.

6. Both axes screws adopt precision ball screws, with scientific pre-stretching assembly process, small thermal deformation and high transmission accuracy.

7. 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.

8. 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.
