Overview
The CHMER ED64QA is a CNC sinker EDM machine from Taiwan-based CHMER, one of Asia's leading EDM specialists. The ED64QA is built for die and mold production, precision toolmaking, and industrial component manufacturing, offering a practical balance of work envelope, surface finish quality, and cost efficiency that has made CHMER a popular choice for job shops and mold manufacturers across Asia, North America, and Europe.
The ED64QA features CHMER's proprietary Q-SERIES adaptive generator, which uses digital spark gap monitoring to continuously adjust discharge energy and frequency for stable, efficient machining across graphite and copper electrode applications. The Q-SERIES generator incorporates automatic arc prevention algorithms that detect and immediately respond to abnormal discharge conditions, protecting both electrode and workpiece from arc damage during complex deep-cavity operations. Technology tables for common electrode and workpiece material combinations are pre-loaded, simplifying machine setup for operators.
The machine's structure combines a precision-cast iron base with hardened and ground guideways on all three linear axes. The large-capacity dielectric tank supports programmable flushing from multiple directions, with independent pressure control for injection and suction circuits. The CNC control system features a color touch-screen interface with parametric programming, automatic electrode wear compensation, and USB and Ethernet connectivity for program transfer and remote monitoring integration.
CHMER's ED-QA series is available in multiple size variants, with the ED64QA offering a mid-size work envelope suited to automotive stamping dies, plastic injection mold cores, and die-casting tool production. CHMER machines are distributed in North America through established distributors and are well-regarded for their reliability and cost-per-part efficiency in production environments.

Strengths & Limitations
Strengths
- Competitive pricing makes high-quality CNC sinker EDM accessible to smaller shops
- Q-SERIES digital adaptive generator with automatic arc prevention for stable deep cavity EDM
- Large 1,000 kg workpiece capacity handles substantial die and mold tooling
- Broad distributor network in North America and Europe provides accessible service
Limitations
- Surface finish capability (Ra < 0.3 µm) trails premium Japanese machines in high-polish applications
- CHMER brand carries less prestige than Sodick, Mitsubishi Electric, or Makino for high-end mold shop customers
- Control software interface less refined than top-tier Japanese and European EDM controls

Frequently Asked Questions
01
CHMER's Q-SERIES digital generator provides solid adaptive gap control and reliable arc prevention, performing well for most production die and mold applications. Premium Japanese generators from Sodick (linear motor + AI control) and Mitsubishi Electric (ADVANCE pulse) offer finer surface finish and lower electrode wear ratios for high-polish or tight-tolerance applications, but at significantly higher machine cost.
02
CHMER has an established distribution and service network in North America through regional distributors. Parts and technical support are available, though response times may vary by region compared to Japanese EDM brands with direct North American subsidiaries.
03
Yes. The ED64QA handles hardened H13, D2, P20, and similar tool steels routinely. Tungsten carbide machining is also possible with appropriate copper or copper-tungsten electrodes and reduced discharge parameters, though cycle times are longer than for steel.
