Common Problems for CNC Machine Tool Industry:

CNC machine tool is characterized with complex structure (contains circuit, machinery, tools and spare parts, etc) and big size, so the product details and internal structure cannot be observed.

CNC machine tool is expensive about several hundred thousand to millions yuan. New operators are easy to make mistakes to cause machine wear, which may lead a large amount of maintenance cost and bring about big economic losses to enterprises.

After-sale service is difficult. Need to arrange professional technicians to offer on-site and follow-up services. But shortage of professional technicians will require enterprises to input great deal of manpower.


Products display of CNC machine tool manufacturing enterprises is restricted to local appearance and not vivid, and clients cannot make deeper understanding.  

  In the sale process of CNC machine tool, foreign clients always need to prepare field trip to know machine tool operation. It is complex, time-consuming and effort-wasting. Sales may miss the opportunity to land orders.     

CNC machine tool training is generally restricted to theory learning with little operation chance, which leads to unobvious training effect.

Training needs many realistic CNC machine tools for trainees with higher training fee and large investment.

Traditional CNC machine tool training adopts “one-to-one” teaching mode, which largely increases training investment. Besides, multi-person training cannot be performed at same time and training efficiency will be reduced.

Various CNC machine tool certification tests are restricted to theory tests, which cannot detect students’ learning effects and operating skills. 

Working principles of CNC machine tool are complex and not intuitive enough. Trainers need to spend much time and efforts to explain but with unobvious training effect.

The training period of traditional CNC machine tool operators is long for about 3~5 years, and they cannot master new machine tool components and operating methods timely as various CNC machine tools innovate.
