Bolt_Hobbing_Tool_for_Lathe_post_12mm
thingiverse
This tool post is designed specifically for lathes and measures approximately 1/4 inch in size, roughly equivalent to 12mm. The dimensions of the area where the tool post resides are long 80mm by 12mm wide by 20mm high. Overall, the total dimensions of this tool post measure 103 x 32 x 23mm. To print the hobbing tool, it is recommended that you use a very high infill setting and enable support, as there is only a minimal amount of support required. Once printed, remove any excess support material, press in the 608 bearings, and then insert the bolt through the bearings with any necessary spacers. Tighten two nuts on the bottom of the bolt until it is snug but still allows for easy rotation. Next, place the lathe tool holder into position and begin the hobbing process. A speed range of 200-400rpm seems to be optimal for M3 and M4 hobbing. This intricate tool post was created using Tinkercad, a user-friendly online platform.
