Contamination of coolants and loss of cutting fluid through chip waste is one of the most time consuming and costly situations for a company. That is where fluid management comes into play. There are many ways to fight contamination and fluid loss. Loss of cutting fluid and coolants through chip waste can be solved with a briquetter. A briquetter is a machine that compresses your chips and turnings into a briquette squeezing out ninety percent of your expensive cutting oils and coolants. After being removed the fluids contain suspended solids which are small particles released when the scrap is compressed. These particles are filtered out through a filter bag.
Contamination control is important to maintain peak efficiency of the coolant and minimize the time lost from a bacteria breakout. Setting a scheduled test of the coolant and cleaning of the machine is the first step to preventing a bacterial breakout. . Mix your coolants correctly; follow the manufacturer’s directions and proper equipment. Such as a positive displacement proportioner Use of distilled or deionized water is important. Tap water can leave behind calcium, magnesium, silica, and other dissolved solids, which allow bacteria to grow. Remove Tramp oil, which is oil from the hydraulics of the machine or from the stock. If this oil becomes contaminated with bacteria it can turn your coolant into an acid bath. Mechanical skimmers, a coalesce, or a plain old shop vac can be used to remove tramp oil. The use of bactericides and filters is the most common form of prevention. There is a wide variety of filters and coolant additives. Choose the proper products for your coolants and machines.
By taking the steps to manage your coolant and cutting fluids you can prolong the life of your coolants and cutting fluids, control loss through scrap, and save time and money due to contamination.
