The specific replacement time mainly depends on the water quality. If the water is clean, the replacement period can be extended appropriately. At the same time, the equipment itself has the backwashing function, which further extends the replacement cycle of the filter element of the filtering system. I list an approximate replacement cycle for reference below, and the replacement frequency should be determined according to the actual situation. 1. PP cotton filter element. It is usually used as a primary filter, mainly to filter large sediment particles and iron pillars, and needs to be replaced after 3 to 6 months of normal use. 2. Granular activated carbon filter element. Usually used as secondary filtration, it is mainly used to adsorb various chemical substances, such as residual chlorine and pesticide residues in tap water. Generally, it needs to be replaced every 6~12 months after normal use. 3. Ultrafiltration membrane filter element. This is an important filter element in the ultrafiltration machine, which is mainly used to filter bacteria in water. Generally, it needs to be replaced after 1~2 years of normal use. 4.

The technical scheme adopted is: a central effluent filtering device, which is characterized in that it comprises a water tank, a chip removal water tank, a filtering mechanism, an input pipeline, a connecting pipeline, an output pipeline, a low-pressure delivery pump and a high-pressure delivery pump, and the filtering mechanism comprises a filter and a second filter; One end of the input pipe is connected with the outlet of the waste water recovery channel of the machine tool workbench; The other end of the input pipe is connected with the chip conveyor water tank; Both ends of the connecting pipe are respectively connected with the water tank. The filter and the low-pressure delivery pump are connected and installed on the connecting pipeline. One end of the output pipeline is connected with the water tank, and the other end is connected with the end of the machine tool spindle through a rotary joint; The filter and high-pressure delivery pump are connected and installed on the output pipe. The cooling water in the water tank is delivered to the central through-hole of the main shaft through the high-pressure delivery pump to cool the main shaft. The inclined high-level overflow pipe is connected to the side wall of the water tank, and the bottom end of the high-level overflow pipe is located in the chip cleaning water tank. When the liquid level in the water tank is higher than the top of the high-level overflow pipe, the cooling water will automatically flow into the chip cleaning water tank from the high-level overflow pipe to prevent the water tank from being filled. As a supplement and improvement of the above technical scheme, the utility model also includes the following technical features. The filter is a coarse filter and the second filter is a fine filter. The wastewater recovered from the wastewater recovery channel of the machine tool workbench enters the central through-hole of the spindle through two filters, effectively improving the purity of the cooling water. The wood chip cleaning water tank is separated into two chambers by the filter screen. The input pipe is connected with one chamber, and the connecting pipe and the high-level overflow pipe are connected with the other chamber. The recycled wastewater is filtered by the filter screen first, extending the service life of the filter and the second filter. The central effluent filtering device also includes a liquid level sensor, which is installed in the chip cleaning water tank to detect the liquid level in the chip cleaning water tank. A pressure gauge is connected to the output pipe to detect the pressure of cooling water in the output pipe at any time. By setting a coarse filter and a fine filter, the utility model can achieve the following beneficial effects: 1. The used cooling liquid is filtered twice, the filtering effect of the cooling liquid is good, and the utilization rate of the cooling liquid is improved; 2.

A large number of practices have proved that every 1 degree change in the workpiece temperature during the processing will result in several micrometers of change within the range of 1 meter. The temperature of iron filings produced in high-speed cutting of workpiece on CNC machining center is up to several hundred degrees. In order to avoid the deformation of the workpiece caused by these high-temperature iron chips falling on the surface of the workpiece, it is necessary to quickly reduce the temperature of the iron chips. Generally, the measure we take is coolant, also called cutting fluid. The selection principle of cutting fluid must meet the requirements of cutting performance and service performance, that is, it should have good lubrication, cooling, rust prevention and cleaning performance, and can meet the process requirements during the processing, reduce tool loss, reduce the temperature and roughness of the processing surface, etc. Therefore, the selection of cutting fluid should follow the following principles: First of all, the cutting fluid shall meet the requirements for rust prevention between work procedures and shall not corrode the work pieces. It shall also meet the requirements of equipment lubrication and protection management. In other words, the cutting fluid cannot leave hard colloidal deposits on the guide rail of the CNC machining center, so as to ensure the safety and normal operation of the equipment used. In addition, the coolant selected for CNC machining center shall be free of irritating smell and harmful additives to ensure the safety of users. It also has a good waste liquid treatment method to minimize the impact on the surrounding environment. In terms of service performance, it is necessary to adapt to various processing methods and cooling of various workpiece materials as much as possible, in addition, it should have a long service life. In terms of tools, the production is more smooth. Improve cutting speed and tap more productivity in production. The tool wear is reduced. Reduce the local temperature generated by high temperature during machining, and extend the tool life. Reduce tool replacement frequency and tool consumption.

液压卡盘在日常的应用中压力不能太大也不能太小，太大容易导致内部配件断裂，太小则会导致夹不紧工件。 所以我们日常在使用的过程中压力到底是调整到多大才比较适合呢， 一般来讲我们液压卡盘内部配件承受压力极限为3.5Mpa 所以液压卡盘压力4-18寸之间压力不超过2.5Mpa最为适合， 使用加高爪时候则压力需要调整到原有的一半比较适合了。

液压卡盘和油压卡盘区别是什么，油压也成为液压，所以液压卡盘和油压卡盘指的是同一个东西，哪一种卡盘精度好？其实这个要看你用途而定，如果单卡盘精度气动卡盘精度是最好的，目前最好的可以打到0.5um但是其夹持力很弱。所以目前使用较广的为液压卡盘，就是油压卡盘
