One of the key factors in determining the success of a surface grinding process is the correct choice and application of lubrication and coolant. Surface grinding coolant plays an essential role in achieving optimal performance, efficiency, and precision in surface grinding operations. 

It has a range of purposes in the process, including cooling the workpiece where grinding is taking place, lubricating the grinding wheel and workpiece, removing grinding swarf, and preventing damage caused by increased temperatures.

What is surface grinding coolant and how is it used?

What is surface grinding coolant?

Surface grinding coolant is a specialised solution that is applied during surface grinding processes. It lubricates and cools the workpiece and grinding machinery, facilitating efficient material removal and improving the workpiece surface finish quality. It has been developed to withstand the high temperatures and pressures that are generated during grinding and provides essential cooling and lubrication to the grinding zone. 

How to choose a surface grinding coolant

Surface grinding coolant can be oil-based, water-based, or synthetic, and the choice of coolant will reflect the requirements of the application and the workpiece material. Grinding conditions, such as ambient temperature, will also be considered. 

The coolant's performance characteristics, such as its cooling efficiency, lubricating properties, chip removal capabilities, and corrosion protection should all be considered to ensure it meets or exceeds the desired performance criteria. The choice of coolant should enhance the grinding performance and improve surface finish quality while extending tool life and protecting the workpiece. 

How to use surface grinding coolant

Using coolant effectively during the surface grinding process requires care and consideration before, during, and after the grinding process:

Check Concentration Levels

The recommended coolant concentration levels should be maintained to ensure consistent cooling, lubrication and performance. This can be monitored using refractometers or testing kits, with adjustments made to maintain performance and longevity.

Careful Application

Surface grinding coolant should be applied using appropriate coolant delivery systems, such as flood cooling, mist-cooling, or through-the-wheel coolant delivery. The choice of delivery system will depend on the grinding application, machine type, and coolant properties. Coolant should be distributed evenly across the grinding zone.

Monitor & Maintain

The coolant condition, cleanliness, and performance should be monitored through visual inspections, pH testing, and concentration measurements. Coolant maintenance practices should be implemented to remove contaminants, extend the life of the coolant, and ensure optimal grinding performance. 

Safety Precautions

Always follow recommended safety guidelines when handling, mixing, and disposing of surface grinding coolant to reduce health risks and environmental impact. Appropriate PPE should always be used when handling and using chemicals.
