Hazardous material classification for machining byproducts

Hazardous Material Classification for Machining Byproducts In the精密零件加工 industry, the classification of hazardous materials generated during machining processes is a critical concern. Machining byproducts, such as metal chips, grinding swarf, and coolingants, often contain harmful substances like carbide, chromium, and nickel. These materials can pose significant risks to human health and the environment if not properly managed. According to international standards, such as the Globally Harmonized System (GHS) and the European Classification, substances like hexavalent chromium (Cr(VI)) are classified as carcinogenic and mutagenic. Similarly, cobalt and nickel-containing byproducts are recognized as toxic and allergenic. In the United States, the Occupational Safety and Health Administration (OSHA) regulates these materials under the Hazard Communication Standard (HCS). In China, the Environmental Protection Law and the Regulation on the Control of Pollution by Heavy Metals provide guidelines for handling such hazardous materials. Proper classification involves identifying the physical, health, and environmental hazards associated with each byproduct. For instance, tungsten carbide (WC) dust is classified as a respiratory hazard, while oil-based cutting fluids may contain polycyclic aromatic hydrocarbons (PAHs), which are carcinogenic. Industries must adhere to local and international regulations to ensure safe handling, storage, and disposal of these materials. To mitigate risks, companies should implement waste segregation, use personal protective equipment (PPE), and adopt environmentally friendly machining practices. Compliance with these standards not only protects workers and the environment but also enhances the company’s reputation and sustainability goals.



What is the difference between cnc and CNC lathe there?


CNC (Computer Numerical Control) and CNC lathe are two important concepts in the field of machining and there are many differences between them.Firstly, on a conceptual level, CNC is a type of control. It uses computer programmes to precisely control the movements of the machine tool, including tool trajectories, speeds, feeds, and many other parameters.CNC technology is like an intelligent brain that can e...

Difference between CNC lathe and machining centre？


1. Functional aspectsCNC lathe: mainly used for processing rotary body parts, such as shafts and disc parts. It is processed around the workpiece rotating spindle. For example, processing a cylindrical shaft, CNC lathe can accurately turn the outer circle, inner hole, tapered surface, threads, and so on. The shape of its machining is mainly achieved by the linear or arc movement of the tool on the surface o...
