Recently, the first county-level city of Liaoning Province, China National Heavy Duty Trucks (truck) 4S shop Xingcheng Zhongxiang Automobile Sales Co., Ltd. was grandly opened in Huludao Xingcheng City and passed acceptance. Deputy General Manager Sales Department of China National Heavy Duty Truck and Deputy City of Xingcheng Nearly 200 people including the secretary of the Dongxinzhuang Township and the mayor of Changchun and Xingcheng City took part in the acceptance ceremony.
China National Heavy Duty Truck Sales Shenyang Branch had nearly 10 4S stores in Liaoning Province before, but they are all located in prefecture-level cities, and are still blank in county-level cities. If they can build 4S stores in county-level cities, they will be closer to the market. Better service users.
During this period, China Heavy Duty Truck Shenyang Branch and Zhongxiang Company have communicated, discussed, selected and demonstrated several times, and finally converted a Changchun FAW-liberated 4S shop in the county-level city of Xingcheng, investing 3 million yuan. China National Heavy Duty Truck's AAA 4S shop.
Xingcheng is affiliated to Huludao City, Liaoning Province. It is separated from the middle of the river and is the largest transportation county in China. In 2010, Langzhong County was designated as the direct jurisdiction of Liaoning Province. It is the first and only provincial county in Liaoning Province. . The construction of Xingcheng Zhongxiang 4S shop will make an incalculable contribution to improving the market share of CNHTC products.
During the opening ceremony, user seminars were held to highlight the HOWO-A7 tractors, the A7 car's Man frame, HUV suspension, aluminum gearbox, disc brakes, and light weight, which will bring greater economic benefits to users. benefit.
Classification of gantry type Milling Machine
(1) Divided by form
According to whether the gantry is moving, it is divided into a gantry fixed table mobile type (about 90% or more) and a gantry mobile type (also called bridge type).
The bridge type gantry milling is characterized by a small footprint and a large carrying capacity. The gantry travels up to 20 meters, making it easy to machine long or heavy workpieces.
According to whether the beam moves on the column, it is divided into two types: moving beam type and fixed beam type; the beam moving on the elevated bed is called overhead type.
(2) Divided by system
It is divided into ordinary type and CNC type. There are also manufacturers to develop digital intelligent gantry milling with ordinary milling and CNC Milling – one button conversion, which is more flexible and practical.
(3) Divided by capability
It`s divided into light, medium and heavy (super heavy) gantry milling.
Performance characteristics
The gantry milling machine has sufficient rigidity, high efficiency, convenient operation, simple structure and comprehensive performance.
The specific performance characteristics vary according to the type, model and manufacturer, and have a lot to do with the technology used.Taking the SK series three-axis CNC gantry milling mentioned above as an example, its performance characteristics are:
1. The vertical milling head is equipped with TX400 heavy-duty gantry milling head, double rectangular guide rail, with strong rigidity;
2.Milling head mounted ball screw, pneumatic broach device, servo motor drive;
3.The side milling head is equipped with a V5 gantry milling head with an independent lubrication device. The lifting is driven by an ordinary reducer, and the frequency control is adopted;
4.Universal milling/CNC milling one-button conversion three-axis CNC system, which can be programmed and operated manually by the expansion panel, which is extremely implementable in the actual machining process;
5.The bed is advanced and retracted, the beam is up and down, and the vertical milling head is equipped with a Taiwan ball screw, which is driven by a servo motor;
6.With timing belt and synchronous wheel;
7.Hand-held electronic handwheel unit for easy three-axis tool setting;
8.Unique beam lifting safety interlocking device to ensure the repeatability of the machine tool;
9.The station standard cycloid pump group is continuously lubricated with low failure rate.
