Environmental Protection and Energy Saving of Cutting Technology

Metal cutting machines must take environmental protection and energy saving as important work in the 21st century, namely, realizing green cutting technology. At present, the current green machining process is mainly concentrated on not using cutting fluid, which is mainly because cutting fluid is easily to cause environmental pollution and harm to health workers, and increases the consumption of resources and energy.

Dry cutting is often done in air atmosphere, but also in special gas atmosphere, including nitrogen, cold wind or dry electrostatic cooling technology, without cutting fluid in cutting. However, for some processing methods and workpieces, dry cutting without cutting fluid is difficult to be used in practical application, so Near-Dry cutting - minimal quantities lubricant (MQL) dry cutting appears.

10 ~ 15% of large quantities of mechanical processing in Europe has adopted dry cutting and near-dry cutting. For a variety of processing methods or machine tools, they mainly use near-dry cutting. It usually makes trace amounts cutting oil and a mixture of compressed air gone through machine tool spindle and the hollow passage inside the tools into the cutting zone. In various types of metal cutting machines, gear hobbing machine mostly uses dry cutting.

In short, the progress and development of CNC machine tool technology provide good condition for the development of modern manufacturing, which promotes manufacturing toward high efficiency, high quality and personalized direction. Predictably, as the development of NC machine tool technology and CNC machine tool are widely used, manufacturing industry will have a profound revolution that will be enough to shake the traditional manufacturing mode.
