D3D CNC Torch Table

Hint: See CNC Torch Table Log for build log - pictures from FB posts.

Basics

• A CNC Torch Table that uses a sightly modified version of the D3D Universal Axis
• Can use a gas fuel only torch, a gas fuel-pressurized air torch, a gas fuel-pure pressurized oxygen torch, or a plasma torch

Used For

• Automation of torching/cutting of large parts such as gears for treads
