Honing Coolants

                                     Honing Coolant Considerations

• Coolants serve the following functions:

› Carry-away chips to keep tool free-cutting

› Lubricates cutting area, extends tool life

› Dissipates heat, maintains size & geometry

› Rust protection

• Oil-based coolants feature superior lubricity, but do not dissipate heat well and have negative disposal requirements

• Water-based coolants remove heat effectively and work well with diamond abrasive. Water-base coolants do not work well with vitrified abrasives.

• Water-base is emulsions (mixed water-oil), synthetics (water-soluble chemicals) or semi-synthetics (water and chemistry combined)

• Coolant should be chilled to approx. 68-72 degrees F

                                   What Coolant Should be Used?

• Lapmaster offers several excellent coolants that handle a wide range of honing applications.

› For Steel and other stringy chip materials we offer a coolant with sulfur content and high lubricity additives to prevent tearing.

› For Cast Iron and other easy to hone materials we offer a light honing oil with just enough lubricity to ensure  clean cutting.

› For Aluminum and Brass we offer a light honing oil with high fat content to ensure clean cutting on soft materials

• Many customers have honing coolants in their plants already.  We work with any coolant that will provide the cutting characteristics they need and the finish they desire.

• Many customers want us to use a cutting fluid they use for boring or other operations.  These usually will not be satisfactory for honing.

• We offer testing and trial services that can determine if an existing coolant is acceptable.
