According to US media, more than three-quarters of the new cars purchased by Chinese consumers are foreign brands such as Volkswagen and Chevrolet. The light of Xiali has faded, including Xiali, and more and more domestic brands that are facing difficulties hope to increase sales and keep pace with the times in the brutal shocks expected in the next few years. A 3-Axis CNC Machining Center/Mill is used for creating various industrial parts. This is achieved by using a wide-range of tooling and cutters depending on the type of material being cut and the end product being manufactured.

According to the US "Wall Street Journal" website reported on February 23, the most popular car in China 20 years ago is Xiali, although the low-key, this car still gives the owner a rich and successful feeling.
In January, Xiali’s parent company warned that it expects to lose at most 1.75 billion yuan (about 280 million US dollars) in 2014. This will be the company's second consecutive year of losses. If there is a loss for three consecutive years, its stock will be delisted.
Xiali owners like Liu Jiaxiang (sound) are losing. He said that in the past three years, the glitch caused by the damage of the door handle and the failure of the interior lights made him bored. The 28-year-old engineer said he could feel his Xiali shaking when he was overtaken by a big truck on the highway. Liu Jiaxiang bought a logo 508 last year.
Xiali's producer and state-supported Tianjin FAW Xiali Automobile Co., Ltd. will release its first automatic transmission model this year as part of the company's return plan. Zhang Zhigang, a spokesman for FAW Xiali, said that he firmly believes that Xiali can come over this time. He said that when people realize that the car has many advantages such as fuel economy, it will return.
Although car sales in the Chinese market have increased by 10% annually, many local manufacturers are expected to announce that 2014 results are the worst in years. Great Wall Motor Co., Ltd., regarded as a rising star, expects a net profit of 2% in 2014, which will be the first year-on-year decline in the company's net profit since 2008. Geely Automobile Holdings Co., Ltd. warned that net profit fell by about 50% last year, the first year-on-year decline since 2002. Geely's parent company owns the Swedish Volvo brand. For the decline in net profit, Great Wall Motor explained that the research and development costs are too large, Geely Automobile said that because the company's overall car sales decreased by 24%.
According to government data, the market share of Chinese domestic brand passenger cars in China's domestic market in 2014 was 38%, down from 46% in 2010. The market share of local car brands in the domestic market has dropped from 31% to 22%.
Foreign automakers are starting to introduce more affordable models and enter the last "fortress" of the Chinese auto market. The affluence of life has made Chinese consumers favor foreign-designed cars that are considered safer and more fashionable. In addition, five years ago, China also cut subsidies to help local brands.
Chinese local auto companies are working hard to narrow the gap in quality with foreign brands, but still not as good as the latter. According to a quality survey conducted by JD Power & Associates last year, there are 131 problems per 100 Chinese brand cars, down from 155 in 2013; compared to 95 problems per 100 foreign brand cars.
At the same time, more and more Chinese cities are restricting the number of new license plates in response to congestion and pollution problems, and some cities have adopted license plate auction systems. Analysts and automakers believe that such restrictions will lead consumers to buy bigger, more expensive cars, and local brands are also affected.
Industry observers said that a large number of local car companies will be eliminated in the next three to five years. Smaller brands such as Hafei, Meiya, and Shuanghuan are now discontinued.
A 3-axis CNC Mill works on three separate axes:
X-Axis: Moving longitudinally or [left-to-right"
Y-Axis: Moving laterally or [front-to-back"
Z-Axis: Moving Vertically or [up-and-down"
CNC Vertical Machining Centers can include an additional axis to do specific cutting applications.
Rotary Tables are common as a 4th Axis on mills. They can vary in size and weight capacities and can have a horizontal or vertical configuration. They are generally an add-on to a standard 3-axis mill. The mill will have to have a proper 4th axis interface (generally a 4th axis card, drive and CNC Control) to accept a 4th axis rotary table.
Trunnion Tables can also be an add-on to a vertical CNC Mill. A Trunnion table adds a 4th and 5th axis to a standard mill by incorporating an A-Axis (which rotates around the X-Axis) as well as a C-Axis (which rotates around the Z Axis).
A true 5-axis machine can allow for continuous 5-axis machining simultaneously. This increases both speed and accuracy when machining the part.
CNC Vertical Mills generally have a single spindle, automatic tool changer, work table and CNC Control.
The spindle on a CNC Machining Center can have a wide range of speeds depending on what material is being cut and the depth of cut that is required. Typical spindle speed ranges from 0 to 10,000 RPM. Higher speeds are used for lighter materials including graphite and aluminum among others. Higher speeds can reach 12,000 RPM up to 50,000 RPM and higher.
The Spindle is loaded with tool holders and cutters to achieve the proper material removal. There are many different styles of tool holders including BT and CAT – which have a conical shape as well as HSK, which uses flanges instead of a taper to lock the holder in place. BT and CAT Holders can come in various sizes including 30, 40 and 50 taper depending on the size of tool the cutter requires. HSK (Hollow taper ShanK) comes in a variety of types – A through F – and sizes from HSK-32 up to HSK-160. HSK is considered a better tool holder for high speed machining as there is more surface contact between the spindle and the holder, reducing vibration and keeping the tool from pulling back into the receiver when cutting at high speeds.
A CNC Vertical Machining Center offers different styles of automatic tool changers as well. The most common style is the umbrella-style. This is where the tool holders are loaded into the carousel vertically. The other style is a drum or side-mount style. The tools are loaded in horizontally in this type. This allows for greater part height in the work area and can help accommodate a rotary table, fixture or any additional work holding devices mounted to the table.
