Fine milling of an engine block plane, what cutting fluid is used for HT200

Liannuo SCC730I water-based cutting fluid is a high-performance multi-purpose cutting and grinding fluid made of special high-performance extreme pressure additives, rust inhibitors and other additives. When mixed with water, a stable and transparent solution is formed. SCC730I water-based cutting fluid has good extreme pressure lubricity, rust resistance, cooling and cleaning properties.

SCC730I waterborne cutting fluid has strong resistance to microbial decomposition, and can still maintain its stability under different water hardness conditions, and its service life is more than 5 times that of ordinary emulsified oil.

Choosing the right cutting fluid is not only the protection of the workpiece, but also the protection of the machine tool, the cutting fluid produced by Tianqi special oil in Linqing City, Shandong Province has been committed to China's largest bearing market for more than ten years - smoke shop customers, and sent to all parts of the country, the product variety is complete, the technology is mature, easy to dilute, durable, used at the specified concentration, the life of the diluent is more than 1 year. It has good anti-rust performance and has the function of removing rust. The cooling performance is good, and the tool is more durable.

The diluent is transparent or translucent, and there is no foam during use, and the machine table is non-greasy and the processing visibility is high. This product is clean, environmentally friendly, non-odorous, gives the operator a cleaner working environment, and has no corrosion and swelling effect on the paint and sealing parts of the machine tool. This product is non-toxic and tasteless, and has no adverse reactions to **.

Milling machine processing should be based on fully synthetic cutting fluid, while lathe is fully synthetic, semi-synthetic, and emulsion can be used. The main attention to when choosing a cutting fluid: cooling the heat of the tool, lubrication, and rust prevention.

According to the chemical composition of the oil, cutting fluids are divided into two categories: non-water-soluble (oil-based) fluids and water-soluble (water-based) fluids.

Water-based cutting fluids can be divided into emulsions, semi-synthetic cutting fluids and fully synthetic cutting fluids.

The classification of emulsions, semi-synthetic and fully synthetic usually depends on the type of base oil in the product: emulsions are water-soluble cutting fluids that use only mineral oil as the base oil; Semi-synthetic cutting fluids are water-soluble cutting fluids that contain both mineral oil and chemically synthesized base oil; Fully synthetic cutting fluids are water-soluble cutting fluids that use only chemically synthesized base oils (i.e., no mineral oils).

Each type of cutting fluid will contain a variety of additives in addition to base oils: rust inhibitors, non-ferrous metal corrosion passivators, defoamers, etc., and the selection of cutting fluids can be based on the needs of different metal material processing.

At present, most of the molds for high-strength equipment are processed and manufactured by milling technology, and the high-speed rotating milling cutter is used by the CNC milling machine to pass the knife on the fixed metal blank to cut out the required shape and features. When choosing the content of CNC milling mold, we should give full play to the advantages and key role of CNC milling machine, and at the same time select the appropriate milling cutting fluid to plug in the wings for processing and manufacturing.

First, the type of milling process.

1) Circumferential milling and end milling.

Circumferential milling is milling with a cutter tooth on the circumference of the cutter body, and its peripheral edge plays a cutting role, and the axis of the milling cutter is parallel to the surface of the workpiece. End milling is milling with the cutter teeth on the end face of the cutter body, the peripheral edge and the end face edge play a cutting role at the same time, and the axis of the milling cutter is perpendicular to the surface.

2) Conventional milling and climb milling.

In conventional milling, the cutting thickness of each tooth of the milling cutter gradually increases from zero, which has an adverse effect on the life of the milling cutter and the surface quality of the milled workpiece. Climb milling can improve the life of the milling cutter and the quality of the milling surface, but the cutting impact force of the milling cutter is greater during the climb milling.

Second, the material of the milling process.

1) Milling of composite materials.

Carbon fiber composites are extremely wear-resistant and strong, so they require the use of hard, sharp, solid carbide milling cutters with a special surface coating. In addition, the fiber content and fiber orientation have a significant impact on the process, which determines the cutting speed, feed rate and toolpath.

2) Milling of titanium alloys.

Titanium alloys have low thermal conductivity, process hardening and other factors. Titanium cutting tools offer excellent performance, but they can be less versatile when dealing with a wide range of different materials. When the workpiece geometry is extremely complex, carbide tools should be used.

3) Inconel milling.

Inconel (nickel-base superalloy) is the most difficult material to cut. They have extremely low heat conductivity and extremely high strain hardening, even higher than titanium alloys. As a result, the more abrasion occurs on the tool, the tool is coated with titanium aluminum nitride, which has an extremely smooth and fine surface roughness.

3. Milling cutting fluid.

The factors affecting the ultra-high-speed cutting accuracy are mainly the performance of cutting benchmark, cutting tool, cutting pass, workpiece raw material, cutting fluid, etc., and how to choose cutting fluid is also an important topic in metal cutting technology

The advantage of milling is that it can be used for metal cutting with complex shapes and high precision requirements, but milling is largely affected by the tool material, workpiece hardness, cutting fluid properties, etc., so it needs to be adjusted many times to meet the process requirements when milling. Zhongfeng special cutting fluid series has good applicability, can be used in turning, drilling, boring, milling, planing, broaching and sawing and other processes, excellent extreme pressure and anti-wear performance can effectively protect the props and improve the accuracy of the workpiece, in the actual use has been widely recognized and highly praised in the industry.

Three points to note:1Knife wiper blade. 2.The rotational speed should be high. 3.The feed should be slow.

Coarse turning, retention 1-2mm, fine turning retention, grinding.

Shaft end face: rough turning, fine turning, grinding;

General planes: rough milling, fine milling, grinding.

Milling machine for processing aluminum alloy:

Aluminum alloy has low density, but relatively high strength, close to or more than steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, is widely used in industry, and the amount of use is second only to steel. In general, it is easy to process, but due to its high plasticity, it is easy to form cutting chips, and black spot corrosion or white spot oxides may be formed. It can be seen that the requirements for cutting fluid in aluminum alloy processing are very tricky, and special aluminum alloy cutting fluid DC-508A must be used.

It is recommended to use micro emulsions or emulsified oils with medium and high oil content that do not corrode aluminum alloys for aluminum alloy milling to protect aluminum alloys and tools, and process efficiency blocks.

High-speed milling because the cutting fluid is easy to produce foam if the speed is fast, so you should choose a cutting fluid with good defoaming, emulsion or microemulsion, and then choose the right cutting fluid according to your processing material and processing difficulty.

Milling machine lathe selection of cutting fluid, there is no difference in cutting fluid, according to the machine tool with the selection, more according to the selection of processing materials, milling machine processing should be fully fit, cutting fluid, the main lathe is full, half-combined, emulsion are used to choose cutting fluid, the main attention: cooling, tool heat and lubrication, prevention.

Stainless steel processing technology generally adopts turning, milling, drilling, reaming, boring, etc.

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

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

Fully synthetic cutting fluids:The oil content is zero, and the performance: good cooling performance, good stability, long service life, but poor lubrication and anti-rust performance.

According to the requirements and characteristics of the machining process, select the appropriate stainless steel cutting fluid for trial.

Stainless steel has poor thermal conductivity, and it is better to use aqueous coolant.
