Used Alliant CNC Machines & Tool Room Equipment for Sale

Alliant vertical knee mills entered the American machine tool market through the Robert E. Morris Company, one of the largest machinery distributors in the northeastern United States. According to machinist community accounts, the brand was created after Bridgeport announced it would sell factory-direct, prompting Morris to source a Taiwanese-built equivalent that matched Bridgeport geometry while addressing several complaints machinists had raised about the original design. The resulting Alliant line offered comparable capability at a lower price point and quickly found a following in job shops and toolrooms across the country.

The core of the Alliant product line is the vertical knee mill, offered in both step-pulley and variable-speed configurations. Common table sizes run from 9" x 42" to 9" x 54", with variable spindle speeds typically ranging from 60 to 4,500 RPM and a standard R8 spindle taper. Key construction features include Meehanite cast iron frames, chrome-hardened dovetail ways, one-shot lubrication, and swiveling ram heads that tilt up to 45 degrees and rotate 360 degrees. Models such as the RT2, RT2V, 42S, 42VC, and 1-1/2 TMV represent the range most commonly encountered on the used market, and many units were delivered with two-axis digital readouts and power table feeds already installed.

Alliant vertical mills serve a broad cross-section of metalworking industries. General job shops, tool-and-die operations, maintenance and repair facilities, educational machine shops, and small-batch production environments have all relied on these machines for milling, drilling, boring, and contouring work in steel, aluminum, and other common engineering materials. Their Bridgeport-compatible geometry also makes them a natural fit for aerospace component shops and automotive parts manufacturers that already maintain R8 tooling inventories.

Buyers seeking used Alliant vertical mills are drawn primarily to the machines' solid cast iron construction, which holds up well over decades of shop use and resists the vibration that degrades accuracy in lighter-duty equipment. Because the design mirrors Bridgeport geometry so closely, R8 tooling, replacement spindle parts, and aftermarket accessories are widely available and inexpensive. Variable-speed heads eliminate belt-change downtime, and the relatively compact footprint makes these mills easy to fit into crowded shops. All of these factors combine to give used Alliant knee mills strong resale value and a loyal following among buyers who want proven manual milling capability without the premium price of a new machine.
