Test Tools
A grinding project is like all other operations in a machine shop, in that it may be unadvisable to take
trialcutsonanishproduct.Forthisreasonitisgoodtohavesetuportestcuttingtoolskeptaside

2.2 Organizing Your Grinding Project
1. Determine and separate the HSS tools from the carbide tools. Aluminum Oxide (Al

O

) wheels will
disintegrate if you try to sharpen carbide tools with them and, conversely, diamond wheels will plug up
if used to sharpen high speed steel.
2. CBN wheels can be used to excellent advantage on HSS tools, providing 50 to 100 times the life at
10 times the cost of Al

be-
cause the abrasive and bond/backing materials are thermally conductive, absorbing and dissipating
much of the heat produced.
3. Once you have separated the tools, install the correct wheel for the material you are going to
sharpenonthemachine.Generally,onewillhavebetterresultsusingthenergritwheelsandlighter
cuts versus coarser wheels and heavier cuts.
4. Organize the grinding project by separating the tools into groups by size and condition of the tool.
The tools requiring the most work should be left until last as they require more severe cutting action
andavarietyofoperationssuchasendgashingorotheradditionalendproling.
5. Sharpening tools that require heavy work involves additional setups. It is advisable to consolidate
these setups based on similarity. This method helps produce more uniform results through the job,
reduces operator fatigue from repetitive setup and setup error.
• If the end is broken and needs to be repaired, this is a special project. It is probably best
to leave these cutters to the last, as they should be cut off with a cut off wheel and then
  recongured.
• From a time point of view, be selective about which tools to repair, because it requires
keen skills and the use of different wheels such as a cut-off wheel or the use of a wheel
