Machining an Anvil Horn

Steps for machining an anvil horn
True conical horns have the advantage that they can be machine ground or machined to shape. Anvils with conical horns that are not finished are a travesty since it can be done so easily on a machine.

The process is simple. Flame cut the horn to a square or octagonal pyramid and machine the taper. Setup for machining can be done on an angle block OR a special fixture as shown.

Horn Machining Vertical The fixture as shown is horizontal on a lathe but could also be used vertical on a turret lathe or vertical boring mill. This would be the preferred method for production turning large anvils. A combination fixture could easily be used to machine four different sizes of anvil without changing the setup. A similar setup is used for belt grinding cast or forged conical anvil horns. This could be done on a machine tool OR a rotary weld positioner. The belt grinder is supported at the correct angle on a swing arm and only takes seconds to do its job.
