At the Mobile World Congress (MWC), Ford Motor Showcased its latest research in the areas of connectivity, mobile travel, customer experience, data analysis and autonomous driving. When reaming stainless steel, the problems that are often encountered are: grooves are easy to be drawn on the surface of the hole, the roughness is poor, the aperture is out of tolerance, it is bell mouth, and the reamer is easy to wear. Different types of stainless steel have different machinability, and the problems in reaming are also different. For example, when reaming austenitic stainless steel such as 1Cr18Ni9Ti and stainless steel resistant to concentrated nitric acid, the main problem is reamer wear; while for 2Cr13, etc. When reaming martensitic stainless steel, the main problem is that it is not easy to ensure the roughness and dimensional accuracy of the reaming hole.

In recent years, traditional car companies have accelerated the transition from car manufacturing companies to mobile travel companies. Cai Che, chairman of Daimler's board of directors and global president of Mercedes-Benz Automotive Group, said earlier that “it is going to be a bigger concept to look at, such as transportation or travel, which will become the trend and trend of the future. â€
In fact, many automakers have moved in the mobile travel arena. Toyota Motor Co., Ltd. announced that it will invest in Uber. In the future, Toyota will introduce a new car rental method. Consumers can borrow to buy Toyota cars and repay the loans through Uber services. Volkswagen also announced that it will invest in Gett on-demand mobile travel service providers. With a total investment of 300 million U.S. dollars, the cooperation between the two parties is expected to broaden the business model of Volkswagen, and participate in the fast-growing car sharing market such as carpooling, time-sharing and car service; BMW’s “DriveNow†car sharing plan and Mercedes-Benz’s “car2go†intelligent travel solution The program has achieved some success in the mobile travel market.
In this context, Ford Motor Co., one of the world's largest auto companies, is not far behind in the transition to mobile travel companies. As early as 2015, Ford Motor Company announced its smart mobile plan, also in Bangalore, India. A Ford smart mobile travel test, exploring car sharing in small groups with close links such as family, colleagues and neighbors. On the "Ford Brand Innovation Night" event held on April 23 this year, Ford Motor Company CEO Mark Fields said that in the face of the public transportation service market based on travel demand, Ford will not only be a car company, but will also become A "smart mobile" company.
At the 2016 World Mobile Congress held recently, Ford Motor Showcased its latest research on smart mobile travel. “Panda Dynamic Shuttle†is a smart mobile travel project developed by Ford Motor in Dalian. The project uses an algorithm in the mobile application to design the Ford Transit fleet's docking stations and routes more flexibly to meet users' peaks and valleys. Time-consuming car demand provides efficient and affordable travel services.
“The key goal of the pilot project is to explore how to use existing resources more efficiently,†said Lei Xiantong, director of smart mobility strategy for Ford Motor Company in Asia Pacific. “We found that different models are available at different times depending on the number of passengers and location. Service that provides more efficient travel services."
In addition, Ford also announced two smart mobile travel projects in China aimed at mitigating the pain points in large cities: the Tintin parking lock test and the Ford employee smart parking test. Tintin parking lock test Ford car owners use the SYNC system to control the use of parking spaces without manual operation, while the Ford employee smart parking test helps Ford employees in Shanghai solve the parking problem near the office building in a simpler and more convenient way. .
It is understood that Ford Motor's smart mobile program is designed to enhance the company's capabilities in car connectivity technology, mobile travel, autonomous driving, consumer experience and big data analytics. As Ford Motor Company President and CEO Mark Fields said: "We are applying innovation to every aspect of Ford's business, making Ford a product and mobile company, and ultimately changing the way the world travels.
1. Reasonable selection of reamer and reaming amount is the key to ensure the smooth progress of reaming.
2. Improve the quality of the pre-processing process and prevent the occurrence of grooves, ellipses, polygons, tapers or bell mouths, waist drum shapes, axis line bending, deflection and other phenomena in the pre-processing holes.
3. Keep the hardness of the workpiece material moderate, especially for 2Cr13 martensitic stainless steel, the hardness after quenching and tempering treatment is preferably below HRC28.
4. To install the reamer and the workpiece correctly, the reamer must be installed correctly, and the axis of the reamer should be consistent with the axis of the pre-machined hole of the workpiece to ensure uniform cutting of each cutter tooth.
5. Selecting a suitable cutting fluid can solve the chip adhesion problem of stainless steel and make it smooth chip removal, thereby reducing the surface roughness of the hole and improving the durability of the tool. Generally, it is advisable to use vulcanized oil. Adding 10% to 20% CCl4 to vulcanized oil or adding 20% to 30% CCl4 to lard will have a significant effect on reducing surface roughness. Since CCl4 is harmful to the human body, it is advisable to use a mixture of 85% to 90% vulcanized oil and 10% to 15% kerosene. When the diameter of the reamer is large, internal cooling can be used.
6. Carefully pay attention to the reaming process and strictly check the runout of the cutter teeth, which is the key to obtain uniform reaming. During the reaming process, pay attention to the shape of the chips. Due to the small reaming allowance, the chips are in the form of foil rolls or very short spiral coils. If the chips are of different sizes, some are in the form of fine powder, and some are in the form of small blocks, it means that the reaming is uneven. If the chip is in the shape of a strip of spring, it means that the reaming allowance is too large. If the chip is needle-like or fragment-like, it means that the reamer has been blunted. To prevent chips from clogging, you should be diligent in observing whether there are sticky chips on the cutter teeth to avoid excessive hole diameter. When reaming a hole with a carbide reamer, hole shrinkage will occur. In order to prevent the hole from being roughened when the tool is retracted, the situation can be improved by increasing the lead angle.
