Ways To Avoid Coolant Contamination

Tramp oils (including way lube and hydraulic oil leaks by machinery), minerals in the water and other contaminates in machine coolants are food for bacteria and fungi that cause odors and lower pH.  As bacteria multiply it causes increased corrosion and reduced lubricity.  You’ve heard it said – that the best defense is a strong offense. A way to successfully control bacteria is to skim the waste oil and contaminants with a surface skimming device(C-Thru Separator) to collect waste oil and return the coolant back to the sump.  This can extend the life of the coolant by 50 percent.  Remember you cannot recycle a rancid coolant.  (See Machine Side Filter Unit.)

3 Products to Best Reduce Contaminants

  1. The C-Thru Separator is a unique, patented unit designed to remove solid and liquid contamination from coolants and cleaners throughout the metalworking industries.
  2. Machine Side Filter Unit is a portable filter cart that can be easily moved from machine to machine.  It is effective in reducing the amount of particulate circulating in the machine sump.  With regular fluid maintenance, you can extend the life of your coolant and help minimize coolant waste.
  3. Bag Mag – magnetic filtration for bag filter housings.  Magnetic filtration involves placing high intensity permanent magnetic rods in the fluid path, positioned such that all fluid must pass around the rod. This provides sufficient contact to extract ferrous contamination from the fluids.  The rods are periodically removed cleaned and put back into position.

Why Standardizing Coolants Makes Sense

WalloverCoolantIt is very seldom that you can use one coolant formulation for all types of metal and metalworking operations.  But what most people overlook is that using multiple coolant variations is a mistake as well.  In most shops, the general rule is no more than three coolant mixes.  If you consider using different concentrations of the same coolant you will find it will be more cost effective.

With every coolant mix on the shop floor there is also a price tag in addition to the cost per gallon.  For each coolant mix added you must take into consideration more labor and more capital equipment is required to prepare, monitor, store and reclaim each additional mix.  Streamlining your coolant mixes will also reduce freight charges, storage in the warehouse, and reduce the amount of coolant mixers required.  Not to mention the efficiency of the coolant recycling systems when fewer coolant variations are processed.

Quality coolants really do make the difference in your machining operation.

Most companies do not know the actual cost of their machine coolants. They can tell you their price per gallon of the coolant they are using, they even know the cost of disposal, but it goes even further than that – it affects production as well.

It is wise for companies to track the quality of the coolant they use for several reasons. Tool life for example – how often they sharpen or replace worn tools, directly links to the effectiveness of the coolant they are machining with.

Choosing the proper formulation and maintaining the coolant ratio can double, or even triple tool life.

Take into consideration the quality of the surface finish – it is closely related to the tool life on the work piece. Inadequate lubricity and corrosion resistance package in the coolant being used will result in a poor finish. Choosing the best coolant for the application will produce smooth finishes that are free of stains.

Everybody knows the sound that good coolant produces; it’s the “hum” the metalworking equipment makes. Production stays steady and is predictable. On the other hand, improperly formulated or “dirty” coolant will cause erratic, unpredictable production output.

Nobody likes to talk about down time – Frequency of machine adjustment to hold dimensional tolerances, sharpening or replacing worn tools and draining and cleaning the coolant system will dramatically increase when the “right” coolant is not being used.

The last and final consideration on the list is disposal. The amount of coolant disposal is directly related to the number of times the coolant is reused. Each time you are able to reuse that coolant, the disposal costs are cut. All of these cost saving tips should be taken into account when investment in coolant recycling equipment is being considered.
