Although some machining methods are dry these days, most take some type of lubricant or coolant. Cutting fluids from coolant suppliers make it easier to machine parts, and they can greatly speed up the process. They improve your machine’s cutting ability and make it possible to work with a wide range of materials including plastics. However, cutting fluids are sometimes a major shop expense and here are some things you can do to increase efficiency and cut coolant cost.
Coolant Recycling
Do you have a coolant recovery system in place? If so, you might want to consider installing one. Talk to a trusted coolant supplier about the different systems available and find out which coolants work best for them. When you recycle cutting fluids, you save a lot of money on disposal costs, plus you lower the amount of cutting fluids you have to buy for your shop. Over time, the money you save is significant.
Problems with Bacteria
As cutting fluids collect impurities, it can create the perfect environment for bacterial growth. These tiny organisms love many of the ingredients in modern shop fluids from your coolant supplier, including mineral oils and corrosion inhibiting additives. Bacteria can cause your cutting fluids to emit nasty odors as they create hydrogen sulfide.
Bacteria can ruin your coolants and make them less effective. Also, they can expose your workers to problems like skin irritations and infections.
Limiting Bacteria
When you limit what bacteria can feed on, you limit their growth. Make sure your coolant recovery system stays clean with frequent cleanings. Talk to your coolant supplier about coolant additives that fight bacteria. You can also use a pasteurization process or try keeping the PH balanced.
Try to keep your entire shop as clean as possible and only use coolants when they are truly necessary. This will give you a more efficient shop.
