The Ministry of Environmental Protection recently notified the administrative punishment decision of Shandong Kama Automobile Manufacturing Co., Ltd. and Shandong Tangjun Ou Ling Automobile Manufacturing Co., Ltd. to violate the air pollution prevention and control system, and required all levels of environmental protection departments to fully implement the newly revised Air Pollution Prevention and Control Law and severely punish Production of excessive motor vehicles and pollution control devices fraudulent behavior. The two cases, as the first case of the Ministry of Environmental Protection after the 19th National Congress, have a demonstration effect and will have a strong deterrent effect on similar environmental violations.
The relevant person in charge of the Ministry of Environmental Protection said that the carbon light + nitrogen oxides and carbon monoxide emitted by eight light-duty diesel trucks produced by Shandong Kama Automobile Manufacturing Co., Ltd. exceeded the emission standards; the OBD system functional test of 318 heavy-duty diesel trucks produced If it is unqualified, the pollution control device will be falsified, shoddy, and sold as a qualified product. In accordance with the first paragraph of Article 119 of the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, the Ministry of Environmental Protection ordered the Kama Company to correct the illegal activities of motor vehicles that exceeded the pollutant discharge standards, confiscated the illegal income of 12,786.80 yuan, and delivered the goods. The amount of the amount is twice the amount of 514,559.52 yuan, and the total amount of fines and penalties is 527,346.32 yuan. In accordance with the second paragraph of Article 119 of the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, the Ministry of Environmental Protection ordered Kama to suspend production of illegal and fraudulent use of pollution control devices. Remediation, confiscation of 718,194.05 yuan of illegal income, and a fine of 30,496,562.52 yuan twice the value of the goods, a total of 31,214,756.57 yuan. The above various fines and penalties totaled 31,742,102.89 yuan.
The emissions of hydrocarbons + nitrogen oxides and carbon monoxide from 109 light diesel trucks produced by Shandong Tangjun Ou Ling Automobile Manufacturing Co., Ltd. exceeded the discharge standards. In accordance with the first paragraph of Article 119 of the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, the Ministry of Environmental Protection ordered Tang Jun Ou Ling Company to correct the illegal activities of motor vehicles that exceeded the pollutant discharge standards, and confiscated the illegal income of 112,502.48 yuan. The fine of the value of the goods is twice the amount of 69,238,815.16 yuan, and the total amount of fines and fines is 703,361.76 yuan.
The relevant person in charge of the Ministry of Environmental Protection pointed out that the Ministry of Environmental Protection directly imposed administrative penalties on the above two typical environmental violation cases, and issued tens of millions of fines for the two motor vehicle manufacturers, indicating that the Ministry of Environmental Protection had “zero†for illegal sewage disposal. Tolerate" attitude. This move laid a solid foundation for the implementation of motor vehicle and oil product supervision and inspection in the country in 2018. It is an important measure to implement the report of the 19th National Congress of the Communist Party of China and resolutely win the battle against blue sky.
CNC Turning
What is CNC Turning
In CNC turning, a chuck (or specialized clamp) holds bars of material and, as they are rotated, a tool is fed to the piece to remove material to create a specific shape. A turret, which holds a group of tools, is programmed to move along the work piece in three different axes of motion to shape the material according to the assigned specifications.
Since CNC turning involves removing material from a work piece, it`s considered a [subtraction machining" process. It is done on a lathe machine, which can be used on all types of material, from wood to metal to plastic. It can also be done on a mill or a drill press.
Turning is primarily used to create cylindrical parts. It can be completed on the outside or the inside of a work piece, which is known as boring. The process can also be used to conduct various other operations, including:
· Grooving: Cuts grooves or creates narrow cavities in work pieces.
· Taper turning: Creates a gradually decreasing diameter in a cylindrical shape.
· Drilling: Produces round holes, which are typically for screws and bolts.
· Facing: Cuts a flat surface perpendicular to the axes of the milling cutter.
· Parting: Separates one part of the work piece from another.
· Knurling: Creates vertical, horizontal or crossing lines on the work piece.
· Threading: Makes grooves that can be screwed into other objects.

Suitable Materials for Turning
In turning, the raw form of the material is a piece of stock from which the workpieces are cut. This stock is available in a variety of shapes such as solid cylindrical bars and hollow tubes. Custom extrusions or existing parts such as castings or forgings are also sometimes used.
Turning can be performed on a variety of materials, including most metals and plastics. Common materials that are used in turning include the following:
l Aluminum
l Brass
l Magnesium
l Nickel
l Steel
l Thermoset plastics
l Titanium
l Zinc
When selecting a material, several factors must be considered, including the cost, strength, resistance to wear, and machinability. The machinability of a material is difficult to quantify, but can be following characteristics:
l Results in a good surface finish
l Promotes long tool life
l Requires low force and power to turn
l Provides easy collection of chips
