What to Look for When Buying a Used Sodick
Verify the linear motor drives and ceramic components. Every Sodick machine uses patented flat rigid linear motors on all axes, so check axis positioning accuracy, acceleration response, and repeatability across full travel. Because there are no ball screws, a healthy Sodick linear drive should perform close to factory spec even with significant hours. On sinker EDMs, inspect the ceramic quill/slider on the Z-axis for cracks or chips, as this component is the foundation of Z-axis accuracy. Confirm Meehanite cast iron structures are intact and hand-scraped surfaces show no scoring.
Test the power supply, dielectric, and wire path. On wire EDMs, verify the SPW Smart Pulse Wire generator or earlier K-SMC produces consistent cut quality across the full power range. Test automatic wire threading, wire tension servo, and break recovery. Check dielectric filtration (triple filtration on most AG models), ion exchange resin, and deionization levels. On sinker EDMs, test the SP Power Supply for discharge stability across roughing through finishing. Inspect dielectric tank, circulation, and temperature management. On AL-G series, confirm the three-sided automatic vertical machining tank operates.
Check the controller, glass scales, and automation. Sodick machines run the proprietary M4-LINK or earlier K-SMC motion controller with absolute linear glass scale feedback. Confirm the controller boots, operates, and all functions are accessible. On high-speed mills (HS, UH series), verify the linear motor spindle, tool changer, and motion control. On machines with SRC80 robot cells, confirm the robot, ITS pallet system, ATC, and JMSPro scheduler are functional.
Sodick Wire EDM Series
AG Series (Production Wire EDM)
The AG400L and AG600L (and taller AG600LH) are Sodick's production wire EDMs with linear motor drives, Smart Pulse generators, automatic wire threading, and triple dielectric filtration. The AG series targets medium to large mold and die, medical, and aerospace work.
AL-P, ALN, AP & AQ Series (Precision, Large, and Nano Wire EDM)
The AL-P series (AL400P, AL600P, AL800P) targets progressive die work with minimal cumulative pitch error. The ALN series (ALN400G, ALN800GH) is the next generation with SPW Smart Pulse Wire control. The AP series (AP250L, AP450L) delivers high-end precision in oil or water dielectric. The AQ series (AQ750L, AQ900L, AQ1500L) covers large work areas and extreme taper, with the AQ1500L offering a 59-inch X axis. The EXC100L is the nano-precision wire EDM for ultra-fine work.
Sodick Sinker EDM Series
AG, AD & AL-G Series (Production and Next-Gen Sinker)
The AG40L, AG60L (best-selling Sodick sinker), AG80L, and AG100L are no-flush production sinker EDMs. The compact AD35L and AD55L target smaller work. The AL40G and AL60G are the next-generation platform with AI functions, SP controller, ceramic slider, precision thermal compensation, and a three-sided automatic vertical machining tank for full automation compatibility.
AP & AQ Series (Micro and Large Sinker)
The AP1L micro-precision sinker reduces EDM time by up to 50% with linear servo motors. The AP3L is a no-flush micro sinker. The AQ15L and AQ20L are Sodick's largest sinker EDMs for automotive-scale molds, aerospace structural parts, and energy components.
Sodick High-Speed Milling, Small Hole & Automation
HS & UH Series Linear Motor VMCs
The HS430L and HS650L are linear motor driven high-speed milling centers for mold and die, electrode machining, and precision components. The HS650L 5-Axis adds A and C axes. The HS150L runs to 40,000 RPM. The UH430L and UH650L extend the platform. The UX series is purpose-built for in-house electrode production to pair with Sodick sinker EDMs.
Small Hole EDM & Automation
The K1C, K1BL, and K3HN small hole EDMs feature the latest servo technologies for high-speed drilling of cooling holes in turbine blades and starter holes for wire EDM. Sodick automation includes the SRC80 articulated robot (80 kg max, ITS pallet positions, JMSPro scheduler), ATC units (ATC-16E, ATC-32E, ATC-12S, Shuttle ATC), and EROWA ITS tooling compatibility.
How to Sell Your Used Sodick
Sodick machines hold strong resale value due to ball-screw-free linear motor technology that maintains accuracy over the machine's life, the broad installed base of AG, AL, and AQ wire and sinker EDMs, and ongoing OEM support through Sodick Inc. in Schaumburg. Low-hour AG600L, AL40G, AL60G, ALN400G, AP250L, and HS650L with current controllers are in high demand.

Frequently Asked Questions About Used Sodick Machines
Are used Sodick EDM machines reliable?
Yes. Sodick has shipped over 50,000 linear motor driven EDMs since the late 1990s. Because Sodick eliminates ball screws, the linear motor drives maintain initial mechanical precision semi-permanently with no wear-related degradation. Parts and service are supported through Sodick Inc. in Schaumburg, Illinois.
What makes Sodick's linear motor technology different?
Sodick uses patented flat rigid (planar) type core linear motors on all X, Y, and Z axes. Unlike ball-screw-driven machines, Sodick's non-contact linear drives have no mechanical wear, no backlash, and no degradation over time. This is combined with absolute linear glass scale feedback, hand-scraped Meehanite cast iron, and in-house ceramic components for Z-axis rigidity and thermal stability.
What should I inspect before buying a used Sodick?
Verify linear motor drive health and axis positioning, ceramic quill/slider condition on sinkers, power supply function (SP or SPW Smart Pulse), dielectric filtration and deionization, wire threading and tension servo on wire EDMs, M4-LINK or K-SMC controller state, glass scale feedback, and automation (SRC80, ATC) if equipped.
Which Sodick models hold their value best?
AG600L and ALN400G wire EDMs, AG60L and AL40G/AL60G sinkers, AP250L high-precision wire, AQ750L large-format wire, and HS650L high-speed mills hold the strongest residual values. Call (844) 478-8181 for valuations.
