CNC工厂注意！40kHz洗不掉切削液？选对全自动超声波清洗机才省钱

　　Attention CNC factory! Can't the cutting fluid be washed away at 40kHz? Choosing the right fully automatic ultrasonic cleaning machine saves money

　　对CNC工厂的老板们来说，零件清洗是生产环节里绕不开的一环，而全自动超声波清洗机更是不少工厂的标配设备。但很多老板都遇到过同一个头疼问题：用40kHz的超声波清洗机处理零件上的切削液，怎么洗都洗不干净，工件表面残留的油污不仅影响后续加工精度，还得反复清洗浪费水电和时间，相当于白烧钱。其实问题的核心根本不是设备不行，而是频率选错了！今天就专门给CNC工厂老板们科普，聊聊全自动超声波清洗机的频率选型，教大家一招解决切削液清洗难题，还能省成本。

　　For CNC factory owners, part cleaning is an indispensable part of the production process, and fully automatic ultrasonic cleaning machines are standard equipment in many factories. But many bosses have encountered the same headache problem: using a 40kHz ultrasonic cleaning machine to treat cutting fluid on parts, no matter how hard it is washed, it cannot be cleaned completely. The residual oil stains on the surface of the workpiece not only affect the subsequent machining accuracy, but also require repeated cleaning, wasting water, electricity, and time, which is equivalent to wasting money. In fact, the core of the problem is not that the equipment is not working, but that the frequency selection is wrong! Today, we will specifically educate CNC factory owners on the frequency selection of fully automatic ultrasonic cleaning machines, teach them a solution to the problem of cutting fluid cleaning, and save costs.

　　先说说为啥40kHz的全自动超声波清洗机洗不掉切削液。咱们机加工用的切削液可不是普通油污，它粘性大、附着力强，还常常夹杂着金属碎屑，属于典型的顽固重油污。而40kHz虽然也属于低频段，但它的空化效应强度和冲击力，刚好达不到剥离这类顽固污渍的要求。很多工厂老板跟风选40kHz机型，觉得它通用性强，却没考虑到CNC零件清洗的特殊性，结果就是清洗效果差、返工率高，看似省了设备钱，实则在水电、人工和返工成本上亏了不少。

　　Let's first explain why a 40kHz fully automatic ultrasonic cleaning machine cannot remove cutting fluid. The cutting fluid we use for machining is not ordinary oil stains. It has high viscosity, strong adhesion, and often contains metal debris, which is a typical stubborn heavy oil stain. Although 40kHz belongs to the low frequency range, its cavitation effect intensity and impact force just cannot meet the requirements for peeling off such stubborn stains. Many factory owners and wind select 40kHz models think that it has strong universality, but they do not consider the special nature of CNC part cleaning. As a result, the cleaning effect is poor and the rework rate is high. Although it seems to save equipment money, it actually loses a lot in water, electricity, labor, and rework costs.

　　给大家支个关键招数：换成28kHz的全自动超声波清洗机，就能轻松解决这个问题，一年下来还能省不少钱。为啥是28kHz？因为28kHz属于低频段中冲击力更强的档位，它产生的空化气泡破裂时释放的能量，比40kHz大得多，能直接穿透切削液的粘性层，快速剥离零件表面、缝隙甚至微孔里的切削液和金属碎屑，清洗得更彻底。而且全自动机型能实现上料、清洗、漂洗、烘干一体化操作，不用人工值守，清洗效率比40kHz机型高不少，原来要反复洗2-3遍的零件，现在一遍就能达标。

　　Here's a key trick for everyone: switching to a 28kHz fully automatic ultrasonic cleaning machine can easily solve this problem and save a lot of money over the course of a year. Why 28kHz? Because 28kHz belongs to the lower frequency range with stronger impact force, the energy released when the cavitation bubbles break is much greater than 40kHz. It can directly penetrate the viscous layer of the cutting fluid, quickly peel off the cutting fluid and metal debris on the surface, gaps, and even micropores of the part, and clean them more thoroughly. Moreover, the fully automatic model can achieve integrated operations of feeding, cleaning, rinsing, and drying, without the need for manual supervision. The cleaning efficiency is much higher than that of the 40kHz model. Parts that used to need to be washed 2-3 times can now meet the standard with just one wash.

　　可能有老板会问，换个频率真能省那么多钱？咱们算笔明白账：原来用40kHz机型，每批零件清洗+返工要花30分钟，水电成本20元；换成28kHz全自动机型后，每批零件10分钟就能洗干净，水电成本只要8元，单批就能省12元。按每天加工10批零件算，一天就能省120元，一个月就是3600元，一年下来至少能省2万元。更重要的是，清洗干净的零件后续加工时，刀具磨损减少、加工精度提高，废品率也会下降，这些隐性的成本节省更可观。

　　Some bosses may ask, can changing the frequency really save so much money? Let's figure it out: originally using a 40kHz model, it took 30 minutes to clean and rework each batch of parts, and the cost of water and electricity was 20 yuan; After switching to a 28kHz fully automatic model, each batch of parts can be cleaned in 10 minutes, and the cost of water and electricity is only 8 yuan, saving 12 yuan per batch. By processing 10 batches of parts per day, we can save 120 yuan per day, which is 3600 yuan per month, and at least 20000 yuan per year. More importantly, during the subsequent processing of cleaned parts, tool wear is reduced, machining accuracy is improved, and the scrap rate is also reduced, resulting in more significant hidden cost savings.

　　这里要提醒各位CNC工厂老板，选全自动超声波清洗机时，千万别盲目跟风选高频。很多商家推荐高频机型，说它清洗精度高，但对机加工零件的重油污清洗来说，高频的冲击力根本不够，反而会因为清洗不彻底耽误生产。选机型的核心原则是“按污渍类型匹配频率”：像切削液、机油这类顽固重油污，优先选28kHz这类低频强冲击的机型；如果是清洗精密零件上的细小微粒，再考虑高频机型。

　　Here is a reminder to CNC factory owners that when choosing a fully automatic ultrasonic cleaning machine, do not blindly follow the wind and select high frequencies. Many businesses recommend high-frequency models, saying that they have high cleaning accuracy, but for heavy oil pollution cleaning of machined parts, the impact force of high-frequency is simply not enough, and it can actually delay production due to incomplete cleaning. The core principle of selecting a model is to "match the frequency according to the type of stain": for stubborn heavy oil stains such as cutting fluid and engine oil, priority should be given to low-frequency and strong impact models such as 28kHz; If cleaning fine particles on precision parts, then consider high-frequency models.

　　除了频率，选全自动超声波清洗机还有两个实用要点要注意。一是看清洗槽容量和工装设计，要匹配自家CNC零件的尺寸和批量，避免因工装不合适导致清洗死角；二是看加热和过滤功能，加热能提升切削液的溶解速度，过滤系统能及时分离清洗下来的金属碎屑，避免碎屑二次污染工件，这两个功能能进一步提升清洗效果和效率。

　　In addition to frequency, there are two practical points to pay attention to when choosing a fully automatic ultrasonic cleaning machine. One is to look at the capacity of the cleaning tank and the design of the tooling, to match the size and batch size of our own CNC parts, to avoid cleaning blind spots caused by inappropriate tooling; The second is to consider the heating and filtering functions. Heating can improve the dissolution rate of cutting fluid, while the filtering system can timely separate and clean metal debris, avoiding secondary contamination of the workpiece. These two functions can further enhance the cleaning effect and efficiency.

　　总结下来，CNC工厂用全自动超声波清洗机洗不掉切削液，问题根源就是频率选错了。别再执着于40kHz机型，换成28kHz低频强冲击机型，既能彻底解决清洗难题，又能一年省2万以上的成本。选全自动超声波清洗机的核心是“匹配污渍类型”，而非盲目追高频。如果大家还不确定自家零件该选哪种频率的机型，建议带着零件样品找厂家做试洗，根据试洗效果再做决定，避免买错设备白烧钱。

　　In summary, CNC factories cannot remove cutting fluid with fully automatic ultrasonic cleaning machines, and the root cause of the problem is the wrong frequency selection. Don't stick to the 40kHz model anymore, switch to the 28kHz low-frequency strong impact model, which can completely solve the cleaning problem and save more than 20000 yuan in costs per year. The core of choosing a fully automatic ultrasonic cleaning machine is to "match the type of stain", rather than blindly chasing high frequencies. If you are still unsure about which frequency model to choose for your own parts, it is recommended to bring a sample of the parts to the manufacturer for a trial wash. Based on the results of the trial wash, make a decision to avoid buying the wrong equipment and wasting money.
