1.The major basic parts such as the lathe bed, lathe feet, the middle supporting plate, the spindle box are all made of HT300 cast iron. The whole lathe bed and the lathe feet are all adopt 45 degrees casting structure as a whole. The compact and reasonable symmetric structure ensures high rigidity and bending vibration performance of basic parts. The guide rail surface of lathe bed adopts superaudio quenching and the penetration depth can reach to 2 mm, which provides the guarantee for the stability of lathe for a long time using.

2)The middle supporting plate together with the whole lathe bed, the middle slip plate and the sliding surface of supporting plate are all adopt the line rail technology of Taiwan, with fast speed, eliminating intermittent creep, high rigidity, low friction, and low noise characteristics. With automatic pressure lubrication, it improves the machine accuracy.

3)The feed of X, Z direction adopts the inner loop preloading large-lead ballscrew with double nut so it is of high feed speed. The drive motor connect with screw straightly via elastic coupling. The feed servo motor passes power to the high precision ball screw directly . It is no gap, and it ensures the accuracy of positioning and synchronization for the lathe.

4)The spindle box adopts spindle unit which is of independent type and sleeve structure and it is equipped with high intensity special bearing for spindle. In terms of lubrication, it adopts the Germany special lubricating oil of bearing, which greatly reduces the thermal deformation of spindle unit and improves the thermal stability and accuracy. The torque in the process of chipping is greatly increased too. It uses spindle unit which is high speed, high precision, and high rigidity. The bearing capacity of axial and radial is very strong, the top speed can reach to 6000 RPM (optional A2-5), and the standard is 4000 RPM .
