General steps to cut the selection of the liquid
Selecting the cutting fluid must be determined taking into account complete factors such as machine tools, tools and treatment technology. Before selecting the cutting fluid according to the treatment and precision methods required, restrictions on safety and treatment of waste liquids are implemented. If fire protection and safety are underlined, a water -based cutting liquid should be taken into account. When choosing the water -based liquid cutting, waste liquid emissions must be taken into account and companies should have waste liquid treatment facilities.
For certain processes, such as crushing, water -based cutting fluid can only be used for cutting using carbide tools, oil -based cutting liquid is generally taken into account . Certain machine tools require the use of oil-based cutting fluid when using high synchronization, so do not easily switch to a water-based cutting liquid to avoid affecting the performance of the machine tool. By weighing these conditions, it may be determined to choose oil -based cutting liquid or water -based cutting fluid. After having determined the main element of the cutting fluid, the second step can be carried out as a function of the treatment method, the required treatment accuracy, surface roughness and other elements and characteristics of the cutting fluid , then the selection and cutting fluid can meet the expected requirements. If there is a problem, comments will be made to discover the cause of the problem and improve it, and finally a clear conclusion of selection.
Opportunities applicable for oil -based and water -based cutting fluids
Currently, there are many varieties of cutting liquids, and their performance is good and bad. Generally, the water -based cutting fluid should be used under the following questions:
① Places where the potential risk of the oil -based cutting liquid;
② High -speed feeding cuts and large cutting zones exceed high temperature, produce intense smoke and risk fire.
③ Given the front and rear process process, the use of water -based cutting fluid is necessary.
④ We hope to reduce pollution and dirt around the machine-tool due to oil splashes, oil mist and diffusion surfaces, thus keeping the clean operating environment.
⑤ From the point of view of the price, for the reduction of treatment which requires a low quality of surface of materials and parts that are easy to transform, the use of the cutting liquid with general water can meet the needs of use and can considerably reduce the cost of cutting the liquid.
The oil -based cutting fluid should be taken into account in the following situations:
① When the sustainability of the tool represents a large part of the cutting economy (such as expensive tools, difficult sharp tools, long loading and unloading time, etc.).
② The machine tool has high precision and water is absolutely not allowed to be mixed (to avoid corrosion).
③ When the lubrication system and the machine-tool cooling system are subject to collusion and where the equipment and conditions of treatment of liquid waste are not available
Precautions to cut the liquid
⑴ The cutting fluid should not have an irritating odor and do not contain additives harmful to the human body to ensure the safety of the user.
⑵ The cutting fluid must meet the requirements of lubricating and protecting the equipment, that is to say that the cut of the liquid should not corrode the metallic parts of the machine tool, n ‘Do not damage the joints of the machine and painting, and will not leave hard gelatinous deposits on the machine guide of rails tools, ensuring the safety of the equipment.
⑶ The cutting fluid must guarantee the effect of anti -ist oil between the room process and the part is not colored. When processing copper alloys, the cutting fluid containing sulfur should not be used. When processing aluminum alloys, you should use cutting fluid with neutral pH value.
⑷ The cutting fluid must have excellent lubrication and cleaning performance. Select a cutting fluid with a maximum non -blocking load value value and a small surface voltage, and the effect is good after cutting tests.
(5) The cutting fluid must have a long service life at service and the machining center is particularly important at the moment.
⑹The cutting fluid must be adapted to a variety of treatment methods and a variety of room materials as much as possible.
⑺The cutting liquid must be low in pollution and there should be methods of treatment of waste liquids.
⑻The cutting fluid should be assessed and easy to prepare. To summarize, when users select cutting liquids, they can first select 2 to 3 types of liquids which are considered to have better complete performance on the basis of specific treatment conditions.
