Mar 07, 2008 7. I use a camel brown aluminum oxide wheel for the rough grinding of the lathe tools. Then i do the last bit of grinding on a green silicon-carbide wheel. I find that the silicon-carbide leaves a much better finish and will produce a mucher keener edge than A/O alone. But take it for what its worth - i'm essentially a newb.

Feb 02, 2019 This foray into tool grinding theory was educational but the resulting bits cut too well, so well they chattered in the 7x12 and the Rockwell 10 . Chatter was a problem on both machines during deep cuts with high feed rate until I limited the feed rate by reducing the side relief (see below) and reduced the width of the cutting section.

Grinding a thread cutting tool on a pedestal grinder is not that difficult, but you need to inspect the tool carefully. Accuracy in the tool is of great importance to the outcome of the thread. The design of the high-speed, steel cutting tool for cutting 60-degree unified threads is shown in Figure 2 .

Begin by dressing the grinding wheel. Next, look up the typical angles for the workpiece material, and then follow the steps in Figure A–2. Dip the tool in coolant frequently to keep it from overheating and annealing. Any discoloration on the bit indicates it may no longer be hardened. If this happens, consider starting over again from the beginning.
