Overview
The CHMER G322L is a CNC wire EDM machine designed for precision die cutting, punch and die sets, extrusion tooling, and complex contoured parts across mold making, aerospace, and medical manufacturing sectors. Built at CHMER’s Taiwan facility, the G322L delivers reliable cutting performance and fine-finish capability at a price point that challenges European and Japanese competitors in its travel class.
The G322L features CHMER’s GPMII generator, which provides independent control of pulse frequency, on-time, off-time, and current amplitude to optimize the cutting process for each workpiece material and wire type. The machine’s submerged cutting design maintains the workpiece fully immersed in deionized water dielectric for superior thermal stability and surface finish uniformity, particularly important for tall workpieces where flush consistency is critical.
With X/Y travels of 320 x 220 mm and a maximum workpiece height of 250 mm, the G322L handles a broad range of die plates, cavity inserts, and precision components. The taper cutting capability up to ±15° at 80 mm height enables ejector pin holes, die clearance angles, and reverse-taper features. CHMER’s automatic wire threading system rethreads broken wire without operator intervention, improving unattended operation reliability.
The G322L’s Windows-based CNC control with conversational programming and DXF import simplifies part programming, while its built-in wire consumption management helps operators minimize wire usage. CHMER’s competitive pricing and strong distributor support across Asia, Europe, and the Americas make the G322L a popular choice for shops entering or expanding their wire EDM capacity.

Frequently Asked Questions
01
The G322L accepts wire diameters from 0.10 mm to 0.30 mm, covering the full range from fine-detail cutting with 0.10 mm wire to high-speed roughing with 0.25–0.30 mm brass wire.
02
Yes. The machine’s automatic wire rethreading system and job queue management allow extended unattended operation. Most users program multiple parts or skim passes to run overnight, with the machine rethreading and continuing after any wire breaks.
03
With multiple skim passes, the G322L achieves Ra 0.2 µm or better, suitable for most precision die and mold applications. For mirror-level finishes, additional skim passes with fine parameters approach Ra 0.1 µm.
