What to Look for When Buying a Used Koike Aronson
Koike Aronson Ransome builds cutting machines and positioning equipment for demanding fabrication environments. Here is what to inspect on used units.
On CNC cutting tables, inspect the gantry, rails, and drive system. Check rail straightness and gear rack condition. Verify drive motors and pinion gears for smooth motion without backlash. On gantry machines (Mastergraph, Versagraph), inspect beam straightness and rigidity. Test CNC controller operation and torch height control tracking. On multi-process machines, verify each station (plasma, oxy-fuel, marking) independently.
On plasma and oxy-fuel stations, test cutting performance. Fire the plasma system and run test cuts on scrap material. Verify clean arc transfer and consistent cut quality. On oxy-fuel stations, check solenoid valves, regulators, and torch condition. Test preheat, pierce, and cutting sequences.
On positioners and turning rolls, check mechanical and electrical components. Test rotation speed, tilt range, and load capacity under representative weight. Verify gear trains, bearings, and drive motors. On turning rolls, confirm wheel alignment and speed control. Check the VFD and pendant controls.
CNC Cutting Machines
ShopPro & ShopProXHD
The ShopPro is Koike's compact CNC plasma and oxy-fuel cutting system, available in sizes from 4x4 ft to 5x10 ft. Built with dual-side drive, precision helical gearboxes, and ground linear bearings, the ShopPro delivers industrial accuracy in a small footprint. The ShopProXHD extends plasma capability with a deeper cutting table, and the Katana variant adds advanced controller integration. These are among the most commonly traded compact Koike tables on the used market.
Mastergraph EX2 & Versagraph Extreme
The Mastergraph EX2 is Koike's industrial-grade gantry cutting machine for high-production plasma and oxy-fuel applications. The Versagraph Extreme adds maximum rigidity with FEA-optimized construction. Both support multi-torch configurations with plasma, oxy-fuel, marking, and bevel cutting. Legacy Mastergraph and Versagraph models remain widely installed in steel service centers.
PlatePro, Plate-Fab & Specialty Machines
The PlatePro provides affordable plasma and oxy-fuel plate cutting with sizes up to 6 ft wide and material capacity to 6 inches. The Plate-Fab integrates a unitized downdraft or water table with precision cutting.
Laser & Waterjet Cutting
The FiberPro CNC fiber laser uses FlashCut Pro controller software and a Precitec cutting head for brass, copper, stainless, mild steel, and aluminum. The FIBERTEX Zero features Koike's first-of-its-kind Dual Beam Controlled fiber laser technology. Legacy Lasertex gantry laser systems with Fanuc resonators remain available on the used market. The ShopJet waterjet inherits the ShopPro platform design with KMT waterjet pump systems and 0.0015-inch repeatability.
Welding Positioners, Turning Rolls & Manipulators
The Aronson line includes universal balance positioners, headstock/tailstock systems, floor turntables, and HT Series Skyhook positioners with powered tilt and continuous rotation for loads from under one pound to over 200 tons. Ransome turning rolls (conventional and self-aligning) handle cylindrical vessel and pipe work across the full size range. Cricket-I and Cricket-II welding manipulators provide column and boom platforms for subarc, GTAW, and GMAW processes.

Frequently Asked Questions About Used Koike Machines
Are used Koike Aronson machines reliable?
Yes. Koike Aronson Ransome has manufactured cutting and positioning equipment for over 100 years. All machines are built at the ISO 9001-certified facility in Arcade, New York. The engineering team brings over 250 combined years of design experience, and machines are built for long service life in demanding fabrication environments.
What is the difference between Koike, Aronson, and Ransome?
They are all part of the same company. Koike Sanso Kogyo (Japan, founded 1918) acquired Aronson Machine Co. (Arcade, NY, founded 1918) and later acquired the Ransome Company, a positioning equipment manufacturer. The combined entity operates as Koike Aronson Inc./Ransome. Used machines may carry the Koike, Aronson, or Ransome name depending on the product line.
What CNC controllers do Koike machines use?
Koike cutting machines use the FlashCut Pro controller, the Katana controller, and legacy Koike CNC systems. Some older machines were equipped with Hypertherm EDGE Pro or Burny controllers. Laser systems may include Fanuc controls. Confirm the controller and software version for parts and support availability.
What should I inspect before buying a used Koike?
On cutting tables, check rail straightness, drive accuracy, torch height control, and CNC function. Test each cutting process on scrap material. On positioners and turning rolls, verify rotation, tilt, load capacity, and motor/gear condition. On all machines, inspect electrical panels, safety interlocks, and limit switches.
What Koike models hold their value best?
Mastergraph and Versagraph gantry cutting machines hold strong values for steel service centers. ShopPro and ShopProXHD compact tables maintain steady demand among smaller fabricators. Aronson heavy-duty positioners and turning rolls hold well due to their robust construction. Call (844) 478-8181 for current valuations.
What industries use Koike equipment?
Koike machines serve steel service centers, heavy equipment manufacturers, structural steel fabricators, energy (oil, gas, wind), shipbuilding, transportation, construction, agriculture, and general metal fabrication. Positioning equipment is used across pressure vessel, pipe, and tank manufacturing.
