GEAR CUTTING TOOL
« on: August 24, 2008, 10:30:37 AM »
Attached pictures show one of a few gear cutters made on my engraving machine.The
gear was drawn in CAD and the g-code for the cutter generated via DXF export. The temper of the 1/4" tool blank was removed for cutting by a carbide die grinding tool.Then the bit was mounted in an adapter inside a R8 fixture allowing it to be rotated 10 deg to put a relief on the bit. After cutting of the profile it was hardened and tempered. A modified fly cutter holder allows for positioning the gear cutter face on the axis of the spindle. The gear cutting tool was measured / checked for dimensions and noted allowing for easy setup in the Atlas mill for later cutting of the teeth . You'll need to look my second post for additonal pictures of the cut gear and info.

Hi !

When and if I will finish my CNC retrofit on my BP clone, I want to be able to shape my own cutters.
I was thinking to cut my own timing gears out of 6061T.

Thank you for sharing,

Marius
