ABRASIVES

Processes

• Debinding or Burnout: A low temperature process for slowly removing binders and pore creators from a grinding wheel without altering the shape or characteristics of the wheel. These can be naphthalene or other organic materials. Volatiles are usually given off and these need to be treated with thermal oxidizers.
• Firing: A higher temperature process to form strong ceramic bonds which are critical to the strength and performance of abrasive materials and grinding wheels. Uniform firing leads to more consistent fired products which are critical for grinding wheel safety. Volatiles are also given off in this process and they need to be treated with thermal oxidizers.
