On June 8, the Department of Education of Gansu Province issued the "Notice on Carrying out Supervision of School Safety Work in the Province's Education System" and requested that a one-month school safety inspection and centralized inspection be conducted in the Gansu Provincial Education System from that day. activity. At a recent conference, Wang Jiayi, director of the Department of Education of Gansu Province, said: “The recent safety incidents in the education sector are often unspeakable. The Education Department must ring alarm bells and step up publicity efforts, especially in poor and remote areas. ." This "Notice" places special emphasis on campus traffic safety. The Department of Education requires the implementation of school bus information collection and the actual situation of the vehicle match; school bus registration, change registration status; regular school bus maintenance and inspection; driver qualification and safe driving training situation; In addition, the Ministry of Education of Gansu Province, in issuing “Noticesâ€, focused on the investigation of the construction of teachers’ morals in response to the nationally heated teachers’ and children’s incidents. In 2013, Gansu Province was the “year of Shifeng Shide Constructionâ€. The Department of Education of Gansu Province required the investigation and investigation of violations of the teacher's morality and the investigation of cases, as well as the status of the teachers’ popularization of law. The "Notice" also pointed out that it is necessary to strictly supervise the management of food safety and hygiene and epidemic prevention on campus. Food purchase (certificate), transportation, storage processing and inspection system construction and implementation status; whether the establishment of a canteen regular inspection system, tableware disinfection measures are implemented. It is understood that this comprehensive supervision will last for one month and is divided into three phases. Firstly, education administrations at all levels, colleges, and direct schools in schools must conscientiously deploy the problems of school safety in the region on a case-by-level basis, conduct in-depth rectifications, and submit them to the Education Department after a series of circular investigations. According to the self-review and rectification work of various localities, the Office organizes the inspection team to conduct centralized inspections in some cities, counties, districts, and schools, and publicizes criticisms of departments and schools that do not conduct in-depth self-examination, rectification, and perfunctory work. Ordered a deadline for rectification, supervise the full implementation of strict supervision and rectification work requirements.                                                           School bus sales hotline Box Guideway Machining Centers
Box guideway machining center also call hard rail machining center in China, it refers to a casting part where the guide rail and the bed are integrated, and then the guide rail is processed on the basis of the casting, which is a type of hard guide rail. The shape of the guide rail is cast on the bed, and then processed into a guide rail through quenching and grinding. The hard rail used in the hard rail machining center is generally a rectangular structure, commonly known as a rectangular guide rail or box guide rail. The Box way machining center machining center adopts sliding friction, which leads to a larger contact surface and high rigidity and strength. Therefore, the box guideway machining center is more suitable for heavy-duty cutting and is suitable for heavy-duty mold processing.

1. Able to withstand larger loads, suitable for rough machining machines with large cutting amounts and large feed rates.
2. Due to the large contact area of the guide rail, the machine tool operates more smoothly, making it suitable for factories with high requirements for machine tool vibration.
Disadvantages of box guideway machining centers:
1. Shorter service life. Under the same maintenance and usage conditions, the service life of box guideways is generally shorter than linear guide machining center, because box guideways operate with sliding friction, while linear guide operate with rolling friction, resulting in greater wear and tear.
2. The repair cost is too high. The maintenance of box guideway machining center is much more difficult and costly than linear guideway machining center. If there is insufficient scraping allowance, it may involve disassembling all the large parts of the machine tool, performing quenching and mechanical processing again, and even more importantly, recasting the large parts. The wire gauge only needs to replace the corresponding linear guide, which will not greatly affect the use of related large parts.
3. The running speed of machine is low, and box guideways machining center usually cannot withstand too fast running speed due to their movement mode and the excessive friction they bear, which contradicts the current machining concept to a certain extent. Especially many factory workers do not have the corresponding maintenance knowledge for machine tools. Many times, they only know how to use the machine tool, but largely neglect the maintenance of the machine tool. The maintenance of the machine tool track is of utmost importance. Once the lubrication of the track is insufficient, it can cause the track to burn or wear excessively, which is fatal to the accuracy of the machine tool.
