Numerical control lathe convenient to maintain

The utility model provides a numerically controlled lathe convenient to maintain, relates to the field of numerically controlled lathes, and aims to solve the problems that a driving shaft of a common numerically controlled lathe is continuously in a rotating state, lubricating oil needs to be frequently maintained and added, lubricating oil adding is tedious, manpower is wasted, and machining efficiency is affected. The numerical control lathe is spliced with an oil liquid storage assembly, the oil liquid storage assembly is of a hollow structure, an opening used for discharging oil is formed in the bottom of the oil liquid storage assembly, contact oiling assemblies are installed at the inner bottom end of the oil liquid storage assembly and in the opening, and the bottoms of the contact oiling assemblies make contact with the driving shaft. Before the numerically controlled lathe is used, lubricating oil is controlled to be added into the oil liquid storage assembly to be stored, then the numerically contr
