The hydraulic oil is controlled by a fine temperature-controlled oil tank to ensure that the machine tool operates in a constant temperature environment for a long time. The hydrostatic spindle of the lower grinding disc of the refrigerated trimmer has a high-precision movement, which is a necessary condition for the completion of non-touch grinding. On the one hand, it ensures that the parts and the grinding plate move smoothly under a certain gap, and at the same time creates conditions for the flatness trimming of the lower grinding plate by using the fine turning method. The selection of polishing liquid for polishing machine is very important, it is directly related to the processing quality of polishing machine, so when choosing polishing night, it is necessary to check the quality and function of polishing liquid. In addition, the selection of polishing liquid is also directly related to the processing process of the entire technology and the processing requirements of the product. Therefore, when selecting the polishing liquid, it is necessary to consider multiple practical factors.
The main shaft of the ultra-fine polishing machine adopts ultra-fine hydrostatic bearings, while the main shaft of the lower polishing disc adopts the large-end hydrostatic bearing to support. Compared with the rolling bearings generally used in traditional polishing machines, the motion accuracy of the hydrostatic bearing can be improved by an order of magnitude. From a few microns to a few tenths of a micron, and to improve the motion stability of the machine tool, reduce vibration, the large end face hydrostatic bearing with a diameter of 300mm ensures high bearing capacity and rigidity.
The ultra-fine polishing machine should be installed before use, and the installation of the equipment should be carried out according to the basic map. It is necessary to lay the foundation 10-15 days in advance. When the equipment is installed on the foundation, it is necessary to align the equipment upright, and finally tighten the bare feet.
1. Jet system: At the embrittlement temperature of the product flash, the jet system de-flashes the product, and uses frozen particles to hit the product. Because the frozen particles are small and elastic, they will not be removed after the flash is removed. It will damage the surface of the product, and sometimes it also has a polishing effect on the product;
2. Cooling system: control the cooling temperature of the working chamber, so that the temperature is controlled at the optimum temperature where the product flash is brittle and the product itself is not brittle, and the refrigerant is liquid nitrogen;
3. Input and take-out system: After the product flash is removed, the equipment can intelligently prompt the completion of processing, and the one-button operation mode is adopted, which can quickly take out and put in the product, and the operation is simple;
4. Screening system: in the process of removing product flash, the frozen particles enter the screening system together with the large flash and powder flash, and the screening system will distinguish the large flash, powder flash and frozen particles, and the large flash And powder flash is discharged into a special flash bag, which can be recycled, and the frozen particles continue to be put into use to remove product flash;
5. Circulation system: The circulation system can make the frozen particles enter the ejection system again, so as to be recycled, and also make the whole particle ejection circulation system run continuously and stably, ensure the internal pressure balance of the equipment, and make the equipment run smoothly and continuously.
