Used DMG Mori CTX CNC Lathes for Sale 12

DMG Mori CTX series and Gildemeister heritage

The CTX brand traces its lineage to the Gildemeister CTX line that DMG inherited through the merger that consolidated Gildemeister, Deckel, Maho, and later the alliance with Mori Seiki. The CTX line predates the DMG Mori brand consolidation, and the second-hand market reflects this with CTX machines spanning multiple branding eras (original Gildemeister CTX, DMG CTX, and current DMG Mori CTX) sharing the same fundamental architecture.

CTX alpha, beta, gamma sub-ranges

The CTX line covers three principal sub-ranges. The CTX alpha is the entry universal lathe with a 200 to 250-millimetre chuck, addressing small turned parts in subcontracting and contract manufacturing. The CTX beta steps up in chuck size (typically 250 to 300 millimetres), bar capacity, spindle power, and overall machine size; the beta is the most common CTX in European subcontracting inventory and addresses the bulk of mid-size turned part production. The CTX gamma covers the heaviest CTX configurations with chuck sizes above 400 millimetres and bar capacities exceeding 100 millimetres, suiting energy, oilfield, and heavy hydraulic component work.

CTX configuration matrix

A major part of the CTX value proposition is the available configuration matrix. Base CTX machines are two-axis turning centres with a 12-station turret. Higher configurations add live tooling, a Y-axis (typically labelled as the TC suffix in the model name, indicating turn-mill capability), a sub spindle for second-operation work in a single setup, and a counter spindle with synchronised operation for complete part finishing. Each step adds substantially to second-hand value, and listings should clearly itemise these options.

Sinumerik 840D control

The Sinumerik 840D control with the DMG Mori operate user interface is standard across most CTX generations. Older units may carry earlier 840D versions; later units include enhanced cycle libraries and shop-floor programming aids. Some configurations carry the MAPPS or Operate 4.x interface depending on model year and specification.

Used DMG Mori CTX value drivers

Used CTX lathes benefit from the wide installed base across European subcontracting, which supports operator familiarity, spare parts availability through DMG Mori's European service network, and an established trade in used DMG Mori tooling and accessories. CTX machines reach Exapro from production environments rebalancing capacity or trading up to multi-tasking NTX platforms.

Browse used DMG Mori CTX lathes on Exapro to compare CTX alpha, beta, and gamma configurations across pure turning, live-tooling, Y-axis, sub spindle, and counter spindle variants from verified sellers worldwide. When evaluating a used CTX, verify spindle hours from the Sinumerik control, check spindle and counter spindle bearing condition, inspect turret clamping and indexing repeatability, test live tool drives where present, verify Y-axis backlash and travel accuracy, and request the most recent calibration data and maintenance log. Hydraulic chuck condition, tailstock alignment for shaft work, and the bar feeder compatibility against actual spindle bore are additional verification points.
