Course: WISE Grant MFGT 244 - Preventative Maintenance > Section: Week 2 Reading Industrial Maintenance S5C29 Preventive Maintenance

Complete and submit the 10 question lab assignment for full credit.

Coolant management and maintenance can have a big economic impact on a machine shop. Properly managed it can improve the quality of manufacturing and reduce wear on the machines. It also has the potential to generate large volumes of chemical waste which can be very expensive to dispose of.  Recycling and waste reduction methods will be discussed.

1. coolant concentration
2. refractometer measurements
3. disk oil skimmers used to remove tramp oil from coolant reservoirs
4. handling large volumes of coolant using pneumatic suction and chip filter
5. membrane filtering used coolant to reduce waste products and recycle used coolant
6. "Used" oil management, tramp oil removed from coolant
