| How to Know when to change out your Grinding Coolant
First, check your coolant strength with a refractomer and adjust accordingly to bring the strength back to the recommended specs. Generally, you'll need to be adding water to the mix as it evaporates off faster- not your coolant concentrate. Here are some things to look for: 1) A rancid smell indicates contaminated or spent coolant. Empty & Clean the tank and re-fill with a high quality lubricant. Both Safety Cool and Syntilo coolants Wood Tech supllys offer superior bio-resistant additives to better reduce the coolant from turning rancid. 2) Old contaminated coolant can be a health risk to you and your operators, due to the airborne bateria carried by the mist from your grinder. Symptoms of this include: sore throat , repiratory problems, itchy shin or dermitits. These symptoms are also associated with coolant that is too "rich". Again, the proper use of a refractometer will help you in maintaining proper coolant-to-water ratios. 3) In addition to pre-mature machine wear, old coolant can reduce gringing wheel life expectancy considerably. Old coolant also holds grinding particles in suspension longer, resulting in poorer finish quality and accurancy. 4) Using a high quality water-based grinding coolant will help alleviate these problems. That's why thousands of customers world wide rely on Wood Tech's coolants for increased cost-effective performance results! Click here to go to Grinding Coolant's Main Page.
