Cutting fluid not only effectively reduces friction and temperature during the machining process of CNC honing machines, but also improves machining quality, prolongs tool life, and improves surface quality. Therefore, it plays a crucial role in CNC honing machining. In high demand machining scenarios, the correct use and management of cutting fluid are particularly important.

1、 The function of cutting fluid

The main functions of cutting fluid can be summarized as follows:

1. Cooling effect: During the cutting process, a large amount of heat is generated between the tool and the workpiece, especially during high-speed cutting and hard material processing. The temperature rise seriously affects the machining quality. Cutting fluid can effectively remove heat during the machining process, preventing deformation or premature wear of tools and workpieces due to high temperatures.

2. Lubrication effect: Form a thin film in the cutting area, reduce the friction coefficient between the tool and the workpiece, reduce friction and wear, thereby improving tool life and surface quality during machining.

3. Cleaning function: It can wash away the debris, heat, abrasives and other pollutants generated during the cutting process, keep the cutting area clean, and avoid the adverse effects of pollutants on the machining quality.

4. Rust prevention effect: Rust prevention components can effectively prevent metal surfaces from rusting, protect equipment and workpieces from oxidation and corrosion.

5. Improve machining quality: Through cooling, lubrication, and cleaning, cutting fluid can improve the smoothness of the machined surface and reduce possible defects during the machining process, such as burns, cracks, deformations, etc.

2、 Types and selection of cutting fluids

There are various types of cutting fluids, and choosing the appropriate cutting fluid is crucial for the machining effect of CNC honing machines. Common types include oil-based cutting fluids, water-based cutting fluids, and semi synthetic cutting fluids.

1. Oil based cutting fluid:

Oil based cutting fluid is based on mineral oil or synthetic oil and has good lubricating properties. Due to its excellent lubrication effect, oil-based cutting fluid is suitable for most heavy-duty and high-temperature cutting processes.

2. Water based cutting fluid:

Water based cutting fluid is mainly composed of water and additives, with good cooling performance, suitable for high-speed cutting and light load machining.

3. Semi synthetic cutting fluid:

Semi synthetic cutting fluid is a mixture of oil-based cutting fluid and water-based cutting fluid, which has both lubricating and cooling properties and is suitable for medium load cutting. Its comprehensive performance is relatively balanced and performs well in many applications.

When selecting cutting fluid, it is necessary to make a reasonable choice based on the machining process, machining materials, equipment characteristics, and machining requirements. For example, in CNC honing machining, as honing is a precision machining process, it is often required that the cutting fluid has good cooling, lubrication, and cleanliness to ensure machining quality and improve workpiece surface accuracy.

3、 Instructions for using cutting fluid

The use of cutting fluid directly affects the machining effect and tool life. When using, the following principles should be followed:

1. Moderate use:

Using too much cutting fluid not only wastes resources, but may also lead to excessive lubrication, which in turn affects temperature control during the cutting process. However, if used too little, it cannot effectively remove heat and cause the tool to overheat, so the amount needs to be controlled according to the specific processing situation.

2. Choose appropriate flow rate and pressure:

The flow rate and pressure will directly affect the cooling and cleaning effects. Excessive flow may lead to waste, while insufficient flow may result in ineffective cooling. Therefore, the flow rate and pressure should be adjusted according to the machining process and cutting conditions.

3. Injection position of cutting fluid:

The injection position of cutting fluid is very important in the operation of CNC honing machine. Generally speaking, it should be directly sprayed onto the cutting area, especially the contact surface between the cutting point and the cutting area, to achieve cooling, lubrication, and cleaning effects.

4. Temperature control:

The temperature of the cutting fluid has a significant impact on the cutting effect. Excessive temperature can reduce its lubrication and cooling properties, and may even lead to problems such as excessive oil stains and mold growth. By circulating cooling, it can be maintained within a temperature range to ensure its stable performance.

4、 Maintenance and Management

The maintenance and management of cutting fluid are not only related to machining quality, but also to environmental protection and production costs. Good management can extend its service life, reduce resource waste, and maintain the surface quality of workpieces. The following are the main maintenance and management measures:

1. Regular inspection:

It is necessary to regularly check its concentration, pH value, cleanliness and other indicators. The concentration should be adjusted according to processing requirements and material types. Excessive or insufficient pH value can affect the performance of cutting fluid, and even lead to metal corrosion or tool damage.

2. Replacement and cleaning:

During use, some performance may be lost due to the accumulation of impurities, debris, oil stains, and other pollutants. Therefore, it is necessary to regularly replace cutting fluid or clean and filter it to ensure its stable performance.

3. Recycling and reuse of cutting fluid:

In order to reduce production costs and minimize environmental pollution, it is possible to consider recycling and reusing waste cutting fluids. By means of filtration, separation, and other methods, pollutants and impurities can be removed to restore some of its performance.

4. Environmental management:

The management of cutting fluid should also involve its impact on the environment. Used ones should be disposed of in accordance with relevant environmental regulations to avoid discharge into the environment and causing water source pollution.

Reasonable selection, use, and management of cutting fluids can improve machining quality, reduce costs, and extend the service life of equipment and tools. Therefore, the management of cutting fluid should become an important link in the production process.
