Anqing central station has to go to Henan Gushi

1. Yes, to Huaining railway station, which is anqing west station. It's the original minibus. The fare is still 6 yuan.

2. The reason why the machining center will rust is because the cutting fluid used is water-based, which will not only lead to metal rust and corrosion, but also has no rust resistance, which will lead to machining center rust. In case of this problem, we should choose antirust cutting fluid. For example, the antirust cutting fluid of China Federation machining center is a kind of metal processing fluid specially developed for CNC machine tools. It consists of sulfurized lard, sulfurized fatty acid ester, chlorinated paraffin, epoxy soybean oil as the main extreme pressure lubricant, and is compounded with different proportions of antirust agent, surfactant, epoxy soybean oil It is a new generation of special synthetic cutting fluid for CNC. It is suitable for cutting and grinding of various machine tools and machining centers. It has excellent antirust, lubricity and cooling properties.

3. The most basic function of cutting fluid is to prevent rust. If not, it's better to use tap water directly
in your case, the proportion of cutting fluid is less, which can be solved by adding more.

4. As long as there is no problem with the quality of the spindle, normal use, spot check and maintenance are done, generally there will be no problem
usually, the problem of the spindle is e to the program problem and improper operation, which leads to Tool Collision and machine collision. Cause the spindle abnormal noise, bearing problems, belt fracture and other problems.

5. CNC lathe concentric hole (later "center drill" term) and drill center hole 60; 1 center drill 60; The center hole of CNC lathe is drilled by common center drill
the size of the center hole is based on the diameter D of the cylindrical hole. The center hole of the CNC lathe with the diameter less than 6.3 mm is usually drilled directly with the center drill made of high-speed steel, and there are two kinds of center drills commonly used: type A and type B.

6. At present, China's metal processing technology and milling process capacity has been greatly improved. The development of high-speed spindle in machining center also makes the CNC system of CNC machine tools more automatic. It plays a very important role in China's instrial and processed procts proction, and the service life of various high-speed cutting equipment and spindle equipment in machining center is long< Br > as the spindle of machining center needs to run at high speed for a long time, in order to improve its service life, special attention should be paid to the selection of main parts and auxiliary materials. By integrating the anti-corrosion and wear-resistant technology into the design process, the service life of the spindle of machining center can be greatly improved, and the long-term high-precision and high-speed operation can be realized< No matter the spindle of machining center or other high-speed cutting equipment of common machining center, it is necessary to ensure the scientific design of internal composition and the compactness of internal structure in the setting process, so it can resist the vibration ring operation and adapt to the change of environment at the same time. Scientific internal design is also an important reason for the long service life of machining center spindle< Br > of course, heat dissipation is extremely important for high-speed equipment, especially in summer. If the heat dissipation problem is ignored, the running speed of the equipment will decrease or the equipment will fail, so the spindle of the machining center is also designed with an independent heat dissipation system, Even in the summer when the temperature is high, it can keep the spindle of machining center running smoothly to prevent parts from being damaged e to high temperature< Although the spindle of machining center has a long service life and simple maintenance in the later stage, in the early stage, the spindle company of machining center provides new requirements in the design process, including higher requirements for processing equipment and technology< In general, the spindle components of machine tool will release heat e to energy loss such as friction and oil stirring ring working. When the heat received by the spindle is equal to the heat dissipated by the spindle, the time required for the process is a function of the surface area, surface heat transfer coefficient, specific heat capacity and mass of the spindle< Br > the temperature rise of spindle components includes the temperature rise of related parts inside the headstock, such as the spindle, bearing, transmission gear, box, etc. The research shows that the temperature rise of the spindle plays a leading role in the thermal deformation of the machine tool, and the temperature rise also has different effects on the normal operation and machining accuracy of the machine tool< Br > firstly, the temperature rise of the spindle makes the temperature of each part change with time, which affects the size of the workpiece to be processed; At the same time, the temperature rise also changes the bearing clearance, which affects the machining accuracy. The temperature rise makes the temperature distribution uneven, and causes the change of the position relationship between the parts or parts, resulting in the displacement or distortion of the parts< To rece the thermal deformation of spindle components, we can rece the heat source, heat dissipation, make the temperature rise stable and evenly distributed. Therefore, when the spindle reaches a stable temperature at the maximum speed, the sliding bearing temperature should not exceed 60 ℃, and the rolling bearing temperature should not exceed 70 ℃; High precision machine tools, such as coordinate boring machine spindle bearing temperature should not exceed room temperature 10 ℃< Br > selecting high-quality machine tool spindle has many advantages. At the same time, controlling the temperature rise in the process of use can make the machine tool spindle maintain good working condition and show excellent performance, which is concive to the better operation of the machine tool, so as to play a greater role.
