Three Phase Milling Machine

The two main types of milling machines are vertical milling machines, which feature a vertically oriented spindle ideal for precision drilling and general pocketing, and horizontal milling machines, which use a horizontally mounted arbor built for heavy stock removal and gang-milling operations.

A milling machine typically costs anywhere from $2,500 to $7,500 for small hobbyist benchtop models, $15,000 to $40,000 for professional manual knee mills, and $45,000 to over $100,000+ for industrial CNC machining centers.

The maximum cutting depth of a milling machine depends heavily on the rigidity of the setup, cutter diameter, and material hardness, but standard vertical knee mills typically have a quill travel (Z-axis depth) of about 4 to 5 inches per pass, though multiple passes allow for much deeper total cuts.

Entry-Level & Hobbyist Desktop Units: Small 3-axis routers and engravers (like the Genmitsu 4040-PRO range from $300 to $1,500. Professional & Industrial Machining Centers: Heavy-duty, rigid 3-axis CNC mills (such as toolroom machines from Haas or production vertical mills) typically range from $30,000 to over $80,000 depending on tooling capacity and horsepower.

Yes, owning a CNC machine can be highly profitable—especially in custom manufacturing, prototyping, and small-batch production—because it automates complex fabrication, slashes labor time, and allows you to command high margins on precision metal, wood, and plastic parts.
