1. It can complete a number of processes at one time, such as turning round, milling polygon, picking threads, pulling groove and so on. (Avoiding the second clamping of the product, the finished product is of high concentricity).
2. it can finish milling two, four, six and other multilateral products at one time, also can process taper hexagonal, intermediate milling hexagonal, or hexagonal product head chamfering tail chamfering, curvature products and other multilateral products.
3. The machine tool can realise a number of processes such as high-speed turning of workpieces and low-speed turning of polygonal products.
4. The machine tool adopts the bed and foot of one-piece structure, and adopts the imported linear iso-track, so it is good at resisting vibration and strong in rigidity.
5. The whole series of the machine adopts hydraulic clamping device, which improves the degree of mechanical automation of the machine tool.
6. 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, it can ensure the long-term machining stability of the machine tool.
7. Both axes screws adopt precision ball screws, with scientific pre-stretching assembly process, small thermal deformation and high transmission accuracy.
8. 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.
9. 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.
