What to Look for When Buying a Used Cubic Machinery
Cubic machines are built for high-production environments where cycle time and accuracy matter most. Here is what to inspect on used units.
On gang tool lathes, check the gang tool post and linear guides. Verify that each tool station indexes accurately and holds position under cutting loads. Inspect X and Z axis guide rails for scoring or excess play. On GTV models, confirm positional accuracy within the rated 0.00005-inch specification by running a test cut.
On Swiss-type lathes, inspect the guide bushing and sub-spindle. Measure bar stock runout through the bushing at operating speed. On dual-spindle SD and SG models, verify sub-spindle handoff concentricity and reliable part transfer. Confirm simultaneous front and back machining operates cleanly, and test chucker mode conversion if supported.
On machining centers, verify the spindle and ATC. Cubic VL-series VMCs use CT-40 spindles rated at 10,000 RPM. Test spindle runout and listen for bearing noise across the full speed range. Cycle the ATC through every pocket. On double column models, check table flatness and gib adjustments.
Confirm the control platform. Most Cubic machines run Fanuc controls, with Fagor and Mitsubishi on select models. Verify the control boots cleanly, loads programs without error, and communicates with any integrated bar feeders, loaders, or robotic cells.
Cubic Machinery Gang Tool Lathes
GTV Series
The GTV series (GTV-27 and GTV-42) is Cubic's precision gang tool platform with positional accuracy of 0.00005 inches and rapid traverse of 787 IPM. The GTV-27 handles bar stock up to 27mm, while the GTV-42 accepts up to 42mm. Both feature C-axis capability for milling and cross-drilling, widely used in aerospace, medical, and jewelry applications.
GTmini Series
The GTmini and GTmini Plus are compact gang tool lathes for secondary operations and simple turning. The GTmini Plus adds a slant-bed design, longer travel, and Fanuc 0i-mate control.
PLG Series
The PLG series (PLG-42 and PLG-60) scales the gang tool concept to larger workpieces. The PLG-60 accepts bar stock up to 3 inches with a 10-inch chuck and 15 HP spindle motor. Optional turret capability adds flexibility for parts needing more tool stations.
GT Max Multi-Slide
The GT Max delivers up to three simultaneous cuts from three independent tool slides, combining cam-automatic speed with CNC flexibility for high-volume production.
GT Force Auto-Loading
The GT Force-32 pairs a CNC gang tool lathe with a gantry loader and stacker for unattended production.
Cubic Machinery Swiss-Type Lathes
SG Series
The SG-12 and SG-12Y are 7-axis Swiss-type lathes with 12mm bar capacity, 15,000 RPM spindle, simultaneous front and back machining, and built-in motor rotary guide bushing. The SG-20 increases capacity to 20mm. All SG models run Fanuc controls and convert from guide bushing to chucker mode in minutes.
SD Series
The SD-32 and SD-42 handle larger bar capacities (32mm and 42mm) for medical implants, defense components, and oil country fittings. Complete machining in a single setup reduces handling and improves accuracy.
Cubic Machinery Turn-Mill & Machining Centers
GTM Series (Turn-Mill)
The GTM series (GTM-42 and GTM-60, in single-spindle S and dual-spindle D variants) combines a gang tool post with full Y-axis and multiple live tool stations on a polymer concrete base. Available in 42mm and 60mm bar capacities with Fanuc CNC.
VL Series (Vertical Machining Centers)
The VL-600 and VL-800 are high-speed vertical machining centers with CT-40 spindles, 10,000 RPM, and 24-tool ATCs. The VL-800 provides 31.4 inches of X travel, 17.7 inches of Y, and 19.6 inches of Z.

Frequently Asked Questions About Used Cubic Machinery
Are used Cubic Machinery machines reliable?
Yes. Cubic designs, builds, and supports its machines in Chino, California, with over 30 years of production history. Cubic machines are field-tested in demanding defense and aerospace environments.
What CNC control does Cubic Machinery use?
Most Cubic machines run Fanuc controls, the industry standard for parts availability and operator familiarity. Select models offer Fagor or Mitsubishi. Cubic is a Fanuc Authorized System Integrator.
What is the difference between a gang tool lathe and a turret lathe?
A gang tool lathe mounts all cutting tools on a fixed sliding plate rather than a rotating turret, eliminating indexing time for faster tool changes and shorter cycle times. Gang tool lathes excel on small to medium parts where speed and accuracy outweigh the need for large tool counts.
What should I inspect before buying a used Cubic?
Focus on gang tool post alignment and linear guide condition on gang tool models. On Swiss-type lathes, check guide bushing wear and sub-spindle concentricity. On VMCs, test spindle runout and ATC function. Verify Fanuc control operation and check for pending alarms.
What Cubic Machinery models hold their value best?
GTV-series gang tool lathes and SD-series Swiss-type lathes maintain the strongest resale values due to precision and applicability across defense, medical, and aerospace work. Call (844) 478-8181 for current valuations.
