Not all metalworking shops deal with the same materials and applications, so it makes sense that metalworking fluid isn\u2019t a one-size-fits-all purchase. Some shops require fluid that can meet the strict standards of specific aerospace customers; others can be more flexible with what they choose to use in their metalworking applications. What\u2019s important to consider is how metalworking fluid affects machine performance, and the fluid you choose can either keep your machines running smoothly \u2014 or require you to constantly change the fluid and replace machine parts.<\/p>\n\n\n\n

Using the wrong metalworking fluid can create foam. If you have fine foam that looks like shaving cream or the head on Guinness beer, that\u2019s caused mechanically by pumps or machines. Foam can be difficult to break up and run coolant out on the floor, creating a safety concern around the machine. The other problem caused by foam is that, if you try to cut with it, it will not carry the heat away from the tool and cause it to wear down faster.<\/p>\n\n\n\n

Another problem that can arise with the wrong or low-quality metalworking fluid is that it can create rust on the machinery. Corrosion can form on chucks, vises, and ball screws the table and other surfaces in the machine and also on the metal being machined.<\/p>\n\n\n\n

Poor metalworking fluid can also leave residue on the machine. This can cause the plates to get sticky and gums up the switches. If it gets really bad, the residue can build up in tool holders and the tools could fall out, slowing production, breaking inserts or drill tips on the tools, and potentially injuring workers.<\/p>\n\n\n\n

While odors aren\u2019t strictly related to machine performance, it does affect operator performance, which in turn impacts production. The odor might be caused by the metalworking fluid itself, or from the machining lubricants leaking into the coolant. Metalworking fluids tend to start smelling bad as it ages, not maintained properly, and as workers treat sumps poorly by using it as a substitute for a trash can or spittoon. The metalworking fluid used needs to resist contamination to prevent this performance issue.<\/p>\n\n\n\n
