What are the advantages of using minimum quantity lubrication in machining centers?

1. Advantages:

1. Compatible with high-speed cutting of machining centers

The machining center is a high-speed, high-efficiency processing equipment, which is very convenient in terms of operating speed and response speed. Therefore, the supporting minimum quantity lubrication system also needs to have a fast response time.

2. Reduce costs

The lubricant consumption in minimum quantity lubrication is about one ten thousandth of the lubricant consumption in wet cutting, which reduces the cost of lubricant. At the same time, the power of the minimum quantity lubrication system is compressed air, and the energy consumption is greatly reduced compared with the cutting fluid circulation system. On the other hand, after minimal quantity lubrication replaces the cutting fluid system, it can directly reduce the manufacturing cost of the machine tool itself.

3.Environmental improvement

The use of minimum quantity lubrication will not cause the emulsion to splash when using cutting fluid, and it can protect the cleaning of the working environment and the machine tool itself.

4. Improvement of overall efficiency

Minimum quantity lubrication processing is quasi-dry processing, which can eliminate the workpiece cleaning process during wet cutting, shorten the process chain, and improve the overall efficiency of the production line.

2. Issues that require attention

1. Cooperation between minimum quantity lubrication equipment and machining center: The machining center is a high-speed, high-efficiency cutting equipment, so the minimum quantity lubrication equipment must be seamlessly connected to the machine tool, that is, the equipment must be able to quickly supply oil mist when cutting starts. , but there will be delays.

2. Adaptability: When using internal cooling type minimum quantity lubrication processing, each cutting tool has different internal cooling holes, and the required amount of oil mist will also be different. Since machining centers often replace cutting tools, this will involve adjusting the amount of oil mist. Therefore, it is necessary to require that the amount of oil mist generated by the minimum quantity lubrication equipment has an automatic adjustment function and can be equipped with different cutting tools.

3. The structure of the nozzle: Since the machining center frequently changes tools, and the size of each tool is different, when using external spray type MQL, it is necessary to pay attention to the structure of the nozzle to provide reliable lubrication for each cutting tool.
