Wrong choice of cutting fluid will cost you half the processing cost

When many factories perform machining operations on metal parts, they only care about the tool and speed, but they ignore the important function of cutting fluid. In 2025, there was a mold factory in Dongguan. Due to the use of poor quality cutting fluid, the surface roughness of the workpiece exceeded the standard, resulting in the scrapping of a total of 3,000 parts, resulting in a loss of 150,000 yuan. The correct selection of cutting fluid will have a direct impact on product qualification rate and tool life.

The more expensive the cutting fluid, the better, but the more matching it is, the better

The cutting fluid used in cast iron machining is completely different from the cutting fluid used in aluminum alloy machining. When machining cast iron, you need a cutting fluid with strong cleaning and anti-rust functions. However, when machining aluminum alloy, you need to use an anti-oxidation cutting fluid. There is a precision parts factory in Shenzhen that used general-purpose cutting fluids without thinking during work. Eventually, some white spots appeared on the surface of the aluminum parts and corroded, causing the rework rate to suddenly soar to 30%!

Three crimes of inferior cutting fluid destroying equipment and damaging products

Let’s talk about the first case first. Insufficient lubrication caused the tool to wear faster. There was a drill bit that could have been used for 8 hours, but it was scrapped and thrown away after 3 hours. Let’s talk about the second case, its anti-rust ability is not enough. In 2024, there was a hardware factory in Foshan that used low-priced cutting fluid . The processed screws were rusty after only two days of storage, causing all transactions that the customer had reached to be returned. Finally, let’s talk about the third case. Its service life is too short and the frequency of odor emission is too high. It needs to be replaced in less than a week. As a result, the cost of labor and waste treatment costs have doubled.

Zhonglian Gongrun supplies directly from the source, eliminating the need for intermediate links

In the Pearl River Delta Metal Parts Processing Cutting Fluid Selection Guide , we have a physical warehouse with an area of ​​5,000 square meters, including hydraulic oil, gear oil, cutting fluid and other products. Previously, an auto parts factory in Panyu, Guangzhou had been purchasing goods from agents. At that time, the price of a barrel of cutting fluid was 80 yuan more expensive than now. Since receiving the direct supply service, the factory has saved more than 30,000 yuan in fuel costs within a year, and the product quality is stable and reliable. The frequency of waste liquid treatment has also been significantly reduced from twice a month to once every six months.

Accumulated practical experience in serving more than 1,000 factories for ten years

There are guides on the selection of cutting fluids for processing metal parts after the mold steel is quenched and then cooled, to lubricated during tapping of stainless steel. We have handled hundreds of various processing scenarios. In 2023, there was a pump and valve factory in Zhongshan. Due to insufficient cooling of the cutting fluid, problems such as thermal deformation of the workpiece occurred. After we went to the site for debugging operations, we adjusted the concentration of the cutting fluid from 5% to 8% and switched to a specialized extreme pressure product. Ultimately, the scrap rate dropped directly from 12% to less than 1%.

You just need to tell me the equipment and materials and I will prepare a plan

It is unnecessary to study professional parameters such as viscosity and additives yourself. As long as you explain what metal material you are processing and what kind of machine tool you are using, I will be able to give you a matching solution. Just like when machining titanium alloy, what is needed is a high extreme pressure cutting fluid, but for ordinary carbon steel, a general-purpose cutting fluid will suffice. We provide a service of sending free samples for testing. If you are not sure, try it first before purchasing.
