Detailed Knowledge Of Shenzhen Grinding Fluid

Detailed knowledge of Shenzhen grinding fluid

By selecting the appropriate grinding fluid, the machining efficiency and tool life can indeed be doubled. Shenzhen's detailed knowledge of grinding fluid is a secret that many people do not know. Today I will explain it thoroughly to you.

In what processing situations can grinding fluid be used?

Whether you are using stainless steel, alloy steel, or non-ferrous metals such as copper and aluminum, grinding fluid can play its role. In 2025, we conducted a survey in the Yangtze River Delta region and found that more than 80% of mechanical processing plants are still using general-purpose cutting fluids, which results in extremely fast tool wear when processing titanium alloys.

Not to mention ordinary processes such as cutting, milling, and sanding. Even in difficult manufacturing such as tapping and gear hobbing, sanding fluid can play a great role. After a precision parts factory in Hangzhou replaced this abrasive fluid last year, the breakage rate of tapping tools was reduced from 15% to less than 3%.

In processes such as drilling and broaching that are prone to high temperatures, the cooling effect of the grinding fluid is extremely significant. A mold factory in Suzhou conducted actual measurements. When using this product when processing HRC45 mold steel, the surface temperature of the workpiece was reduced by more than 30 degrees compared with ordinary cutting fluid.

Four major performance advantages make processing twice the result with half the effort

The trump card of this grinding fluid is its lubrication and anti-wear properties. We did a comparative test at a bearing factory in Wuxi. When the same grinder was grinding GCr15 bearing steel, after adding the grinding fluid, the surface roughness of the workpiece was reduced from Ra0.8 to below Ra0.4.

Cooling and rust prevention are carried out at the same time, which is particularly important in the humid weather in the south. A hardware factory in Guangzhou reported that the parts processed with this product will not rust when placed in the workshop for three days. However, in the past, products from other brands could only last for one day at most.

Processing accuracy is directly related to cleaning capabilities. An operator working at a CNC machining center in Dongguan told me that after replacing this grinding fluid, grinding debris and oil stains were suspended above the fluid surface, and they no longer adhered to the workpiece and fixture.

Physical and chemical indicators determine the real performance of the product

It is a bright green transparent liquid that allows the operator to clearly see the cutting status. A master craftsman in Ningbo said that in the past, when milky white cutting fluid was used, it was difficult to see the cutting area clearly, and the knife often burned, but now the machining process is clearly displayed.

The pH value is stable between 8.0 and 10.0, which not only ensures the anti-rust effect, but also does not cause irritation to the skin. We tracked 20 users, and after three months of continuous use, no one reported that the operators had skin allergies.

The anti-rust performance test reached 144 hours, which is extremely hard-core data. There is an auto parts factory in Chongqing. With this data, they successfully convinced their German customers and won a total of 2 million orders for the whole year.

Use it correctly to achieve maximum effect

It's not that the dilution ratio is better. A machinery factory in Chengdu initially used a ratio of 1:20 to save costs. However, the tool life actually decreased. Afterwards, it was adjusted to 1:15, and the processing efficiency immediately improved.

If you want to add working fluid, you must add the original solution or a high-concentration diluent. There is a factory in Nanjing that simply added water to save trouble when replenishing the working fluid. As a result, after half a month, the workpieces began to rust, and several batches of products suffered losses.

Can the liquid supply method be selected flexibly? We give this suggestion. For heavy-duty machining, the high-pressure method is used, while for precision machining, the overflow method is used. There is a gear factory in Zhengzhou that uses boring processing efficiency improvement techniques . It uses the spray method to process small-module gears, which ultimately improves the machining accuracy. The improvement is by one level.

These precautions must be kept in mind

Water quality is indeed critical. There is a factory in Qingdao that uses tap water to prepare liquid. As a result, the liquid it prepared deteriorated and smelled in less than a week. After switching to demineralized water, a barrel of working fluid remained as clear as new after two months.

The key to extending the service life is to keep it clean. A precision machinery factory in Shanghai has specially formulated operating regulations. The regulations prohibit the use of working fluid for hand washing and boring processing efficiency improvement techniques , and the debris in the fluid tank must be cleaned regularly. As a result, a barrel of fluid can now be used for three months.

Anti-rust measures must be taken when the machine is shut down for a long time. One factory in Wuhan failed to wipe the machine tools clean before the Spring Festival holiday. When they returned after the holiday, the guide rails were already corroded, and it cost 80,000 yuan to replace the guide rails.

Enhanced program for special occasions

When processing heavy loads, extreme pressure anti-wear agents are used to achieve the most ideal results. There was a heavy machinery factory in Shenyang that added extreme pressure agents when processing high-strength steel, and the depth of one pass was increased from 2mm to 3.5mm.

For materials that are difficult to cut, the concentration can be appropriately increased. There is an aerospace parts factory in Xi'an. When processing titanium alloy, the concentration was adjusted to 1:8, and the tool life was doubled.

When switching between different materials, you need to pay attention to cleaning. There is a factory in Beijing that is engaged in small-batch production of many varieties. Every time before changing materials, cleaning agents are used to thoroughly clean the liquid tank to prevent cross-contamination from affecting the processing quality.

When choosing grinding fluid every day, which indicator do you pay most attention to, the lubricity or the anti-rust ability? You are welcome to share your own experience in the comment area. If you find it useful, please give it a like so that more peers can see it.
