- The main body is made of is high-quality cast iron. With advanced finite element analysis technology, the design structure is reasonable and the layout is optimized. And after secondary aging treatment, it can ensure the long-term processing stability of the machine tool.
- The two axes adopt precision ball screws, combined with scientific pre-stretching assembly technology, ensuring small thermal deformation and high transmission accuracy.
- The screw support uses precision bearings from well-known brands, and high-precision lock nut is used to improve the support and locking accuracy of the screw and further improve the processing accuracy of the machine tool.
- An automatic centralized lubrication system is adopted to lubricate moving parts such as screws and guide rails through set oil injection intervals and oil injection times to ensure the normal use accuracy and service life of the machine tool.
- The main shaft bearing adopts precision angular contact ball bearings, which can obtain an optimized combination of high precision, high load-bearing capacity and high speed, and are durable. It can also be equipped with imported spindle bearings and a powerful main servo motor, which ensures smooth operation and high precision.
- One-piece casting molded one-piece lathe, precision large-size linear guides, large-span layout, stable structure, strong rigidity, and good accuracy retention.
