What cutting fluid is used for machining stainless steel?

Stainless steel cutting fluid reference.

Ingredients: Feeding ratio: N46, mineral oil, 22-28, di-butyl phosphite, 20-25, trimethylphenol phosphate, 20-25, potassium borate, 8-12, alkylbenzoic acid, 4-6, sodium sulfated fatty acid esters, 2-4, alkylphenol, ethylene oxide, 5-8.

Preparation method of stainless steel cutting fluid:

After heating the base oil to 45 50, add compound phosphate, potassium borate and rust inhibitor in turn, and keep the temperature at 40 50 and stir for 10min, and keep the stirring speed at 100 120r min, then add surfactant to maintain the original stirring speed, stir until completely transparent, and package after natural cooling.

Stainless steel has high tensile strength, yield strength, elongation and impact value in terms of mechanical properties, as well as corrosion resistance and high temperature resistance, as well as high thermal conductivity. So what kind of cutting fluid should be selected to be suitable for stainless steel machining? From the performance characteristics of stainless steel, it can be seen that the cooling, lubrication and penetration of cutting fluid are relatively high.

In terms of coolability, the cooling efficiency of oil-soluble cutting fluid is very low. For stainless steel cutting, due to its own characteristics of low conduction points, it is not easy to carry out effective cooling of oily cutting fluids. In actual operation, the cutting oil often smokes due to the large machining allowance and the failure to dissipate heat in time due to the large machining allowance, which affects the machining.

The water-soluble cutting fluid quickly dissipates the heat generated during cutting to achieve the ideal cooling effect.

Water-soluble cutting fluids are divided into emulsion, semi-synthetic cutting fluids, and fully synthetic synthetic fluids, although the fully synthetic fluids are the best in terms of cooling performance. However, its lubrication is poor, it is difficult to form an ideal lubricating film in processing, and it is easy to produce direct contact between the tool surface and the workpiece to form the so-called dry friction, so that the contact length between the tool and the chip becomes longer, and the shear angle becomes smaller, thereby increasing the cutting difficulty. Therefore, it is difficult to meet the requirements of stainless steel cutting processing with boundary lubrication as the main focus during cutting.

The oil content of the emulsion is 50%-70%, and the lubrication performance is excellent, but the life is short and it is easy to smell. Semi-synthetic cutting fluid DC-507

It combines the performance of emulsion and fully synthetic cutting fluid, which is the most cost-effective, and is also the most commonly used one by cutting fluid manufacturers and processing plants.

You should be talking about green cutting fluid, most of the green cutting fluid is semi-synthetic or fully synthetic, and the milky white is the emulsion.

Emulsion DC-503: oil content is greater than 50%, performance: good lubrication and anti-rust performance, but poor cooling performance, poor stability and short life.

Semi-synthetic cutting fluid DC-507: oil content 5%-30%, performance: excellent lubricity, rust resistance, cooling, long life, good comprehensive performance, wide range of use.

Fully synthetic cutting fluid DC-505: zero oil content, performance: good cooling performance, good stability, long service life, but poor lubrication and anti-rust performance.

In response to your question, if there is nothing wrong with the emulsified oil you are using now, then there is no need to change the oil. If the emulsion oil used is not effective, it is recommended to replace it with a semi-synthetic cutting fluid.

Stainless steel has poor thermal conductivity, and can be cooled with aqueous coolant.

Answer: You can choose stainless steel drilling fluid, SCC310 stainless steel drilling fluid is designed for high-speed extreme pressure processing process, can adapt to stainless steel, stainless steel strap drilling processing of cutting fluid. SCC310 stainless steel drilling cutting fluid effectively and quickly precipitates the finest chips and improves surface finish.

Stainless steel has high resistance and high cutting temperature during cutting, which leads to serious tool wear, reduces productivity and increases processing costs. At the same time, it is easy to stick to the knife, resulting in built-up edge, which affects the accuracy and surface finish of the processed workpiece.

1. Excellent cooling performance to ensure that it can effectively reduce the heat during machining and cutting.

2. Stainless steel has great toughness, and it is easy to produce nodules and deteriorate the machined surface during cutting, which requires stainless steel cutting fluid to have excellent lubrication performance and play a good lubricating role.

3. Stainless steel cutting oil should have good permeability, and can play a good role in wedge, diffusion and internal lubrication for chips that are not easy to be cut off.

For high-strength stainless steel machining, choosing the appropriate special stainless steel cutting oil, as well as professional lubrication technical guidance, can not only effectively extend the tool life, improve processing efficiency, and reduce the production cost of enterprises! Moreover, in terms of workpiece processing accuracy, it can effectively improve the processing accuracy, greatly meet the needs of processing, and improve the technical competitiveness of enterprises.

Stainless steel drilling, tapping using edible vinegar is good, you can also use copper sulfate solution is also good.

What cutting fluid is used for machining stainless steel materials? First of all, if you only process stainless steel, if you only process stainless steel, it is recommended that you use a special cutting fluid for stainless steel, the effect will be better. Secondly, if you also have other materials such as copper, aluminum, iron and other metal materials, it is recommended that you use a universal cutting fluid, which is easy to operate.

This requires the use of stainless steel special cutting fluid, and choosing the right cutting fluid is not only for the protection of the workpiece, but also for the protection of the machine tool. Linqing City, Shandong Province Tianqi special oil production of cutting fluid variety, stable quality, mature technology, products for more than ten years committed to China's largest bearing market - tobacco shop customers, and sent to all parts of the country, easy to dilute, durable, in the specified concentration of use, diluent life in more than 1 year.
