SCOPE:

To design & build a Hard Facing Station for cones of Tri Cone Drilling Bits. These drill bits are used in mining industry. These come in various product variants and are even heavy in sizes. Hard facing is a carbide material deposition process using extreme heat over the surface of the drill bit cone. Three of these cones join to form a Drill Bit Each.

EXISTING PROCESS:

Currently hard facing process is a manual Load / unload process. The cones are manually placed, clamped on the fixture, and rotated at multiple angles to reach desired positions for hard facing.

CHALLENGES:

Product being heavier in weight, makes it difficult to handle manually.
The proposed station needs to accommodate all product variants
All the hard facing locations to be ergonomically accessible
