According to a research report by the German Automotive Management Center (CAM), the Chinese and American markets play an increasingly important role in the automotive industry. Since 2010, total sales in these two major markets have increased by 12 million units, while sales in the Western European market have dropped by 900,000 units. Some experts said that in a short period of time, the sales volume in the US and China will occupy half of the world.
Research by the German Automotive Management Center shows that the most successful car companies have benefited from the growth of the Chinese market. The best example is the Volkswagen Group, which sold 37% of its worldwide sales in China in 2014, while the local Western European market accounted for only 31%. In 2014, Peugeot Citroen Group's sales in China increased by 32% in China, and the Chinese market accounted for 1/4 of its total worldwide sales. The Daimler Group’s sales in China also accounted for 29% of its total worldwide sales.
In comparison, the US market is more important to Japanese car companies. For example, Subaru's sales in the United States increased by 21% year-on-year, and more than half of the cars sold in the US market (56%). Toyota's US sales also accounted for 24% of its total worldwide sales. However, Ford's sales in the United States fell by 0.6% year-on-year, and even worse, Volkswagen's total sales fell 2% year-on-year.
Statistics show that in 2014, the world's largest 17 car companies total sales reached 74.9%, an increase of 3.8%. Among them, Daimler Group and BMW Group took the lead with 9.9% and 7.9% sales growth respectively. Volkswagen Group and Hyundai Motor, which are targeting the mass market, also achieved growth of 5.9% and 4.5%, becoming market winners.
It is reported that in 2015, the sales competition of the three major automobile groups will enter a new stage. In 2014, Toyota sold a total of 10.06 million cars, while Volkswagen sold 9.94 million. The German Automobile Management Center expects that Toyota's total sales volume will reach 10.25 million units in 2015, and will continue to maintain its leading position in the world. Volkswagen will rank second with sales of 10.2 million units, and the gap with Toyota will further narrow. Sales in the US market are hard to beat Toyota. Affected by the continued growth of the US market, GM is expected to achieve sales of nearly 10.2 million units in 2015, ranking third.
Operated with Computer Numerical Control (CNC) systems and provided with precise design instructions, CNC Lathes are machine tools where the material or part is clamped and rotated by the main spindle, while the cutting tool that work on the material, is mounted and moved in various axis.
CNC Lathes are normally used for machining parts, where the material / part is clamped and rotated whereas the cutting tool is stationery mounted for OD (Outer Diameter) and ID (Inner Diameter) operations, e.g. shafts and pipes. They are ideal for parts that have same symmetry around an axis that could be chucked up (i.e. radially clamped) in the spindle.
A simple CNC Lathe operates on 2-axis and the tool is located in a fixed position at 8 to 24 station turret. The rotating action of the part is called [turning", hence certain types of CNC Lathes are called CNC Turning Machines.
Milling (cutting tool moves around stationery workpiece), boring and tapping (a tool that cuts threads inside hole) tools are normally driven by a separate drive system inside the turret. Depending on the application, the life tools (i.e. active tool) are mounted for axial or radial operational directions. These could be found in 3-axis CNC Lathes or CNC Turning Machines.
Lathe machines with additional options such as Y-axis, sub-spindles, or specific selected options for automation are commonly called Turning Centres. These sophisticated machine tools are capable of machining complex parts – these go beyond standard OD & ID turning operations and may incorporate milling, drilling and tapping operations to complete the part in one setting. Taking a piece from raw part to finished product, such all-in-one machine tools significantly improves productivity.
