Overview
Makino is one of the most respected names in sinker EDM, offering a comprehensive lineup that spans from compact precision machines to massive industrial die sinkers. The Japanese manufacturer has been building EDM equipment since the 1960s and has consistently pushed the technology forward with innovations in generator design, spark gap monitoring, and control systems.
Makino's sinker EDM lineup divides into two main tiers. The EDGE series (EDGE2i, EDGE3i) targets value-conscious shops that need solid Makino EDM technology at a mid-range price point, with travel ranges from 350 x 250 mm up to 450 x 350 mm. The premium EDNC series (EDNC-6 through EDNC-20) is built for production environments demanding the highest precision, generator power, and automation capability, scaling from 400 x 300 mm travel up to a massive 1,100 x 800 mm on the flagship EDNC-20.
All current Makino sinker EDMs share key technologies. The HS-Rib generator uses high-speed switching to optimize spark energy, reducing electrode wear while maximizing metal removal rates. ArcFree technology continuously monitors the spark gap and prevents destructive DC arcs that can pit finished surfaces — critical for unattended operation. SGF (Super Geometric Flushing) automatically optimizes dielectric flow based on real-time cavity conditions, eliminating guesswork from one of sinker EDM's most challenging variables.
The Hyper-i touchscreen control is standard across the lineup, providing a consistent operator experience from the smallest EDAC1 to the largest EDNC-20. Guided workflows simplify setup and programming, while advanced users have access to full parameter control. Multi-tool ATC systems range from 16 to 24 positions across the lineup.
Makino sinker EDMs are manufactured at facilities in Japan and Singapore. The company provides global service support through direct offices and authorized distributors. Pricing spans from approximately $80,000 for the compact EDAC1 to over $1,000,000 for a fully configured EDNC-20, with the most popular models (EDNC-6 through EDNC-10) falling in the $200,000-$480,000 range.

Strengths & Limitations
Strengths
- Complete lineup from compact precision to massive industrial machines covers virtually every sinker EDM application
- HS-Rib generator technology delivers industry-leading balance of roughing speed, finishing quality, and low electrode wear
- ArcFree technology provides reliable unattended operation protection across all models in the lineup
- Hyper-i touchscreen control offers consistent operator experience across the entire lineup, simplifying multi-machine shops
- SGF flushing technology eliminates guesswork from dielectric management — one of sinker EDM's most critical and difficult variables
- Strong global service network with direct Makino offices and authorized service centers in major manufacturing regions
- Proven automation integration capability with Erowa, System 3R, and Makino's own robotic cell configurations
Limitations
- Makino EDMs carry a premium price compared to competitors like Sodick and Mitsubishi at equivalent specifications
- Parts and service costs tend to be higher than competitors — budget accordingly for maintenance
- The EDGE series, while more affordable, lacks some of the precision features that define the EDNC platform
- Smaller dealer network than some competitors may limit service accessibility in certain regions

Frequently Asked Questions
01
Makino's current sinker EDM lineup includes the EDAC1 (compact precision), EDGE2i and EDGE3i (mid-range), and the EDNC-6, EDNC-8, EDNC-10, EDNC-15, EDNC-17, and EDNC-20 (production/industrial). The EDGE series targets value and versatility, while the EDNC series delivers production-grade precision and power. Travel ranges from 250 x 200 mm (EDAC1) to 1,100 x 800 mm (EDNC-20).
02
Prices range from approximately $80,000 for a new EDAC1 to over $1,000,000 for a fully configured EDNC-20. The most popular models — EDNC-6 ($200K-$280K), EDNC-8 ($280K-$380K), and EDNC-10 ($350K-$480K) — cover the mid-range production market. Used Makino EDMs offer significant savings, with machines from 2010-2020 available at 40-60% of new pricing.
03
The EDGE series is Makino's mid-range sinker EDM platform targeting value-conscious shops. The EDNC series is the premium production platform. Key differences include generator technology (HS-Rib is more advanced in EDNC), positioning accuracy (±0.001 mm EDNC vs ±0.002 mm EDGE), surface finish capability (VDI 6 EDNC vs VDI 10 EDGE), and ATC capacity (24 positions EDNC vs 16-20 EDGE). The EDNC also includes SGF flushing.
04
Yes, Makino sinker EDMs integrate with both Erowa and System 3R electrode and workpiece holding systems. Most EDNC and EDGE machines can be configured with chuck interfaces for either system. This compatibility is essential for shops running robotic EDM cells, as the standardized tooling interface enables automated electrode and workpiece loading.
05
All three are top-tier sinker EDM manufacturers. Sodick is known for linear motor drives and the LN2W power supply for ultra-fine finishes. Mitsubishi offers excellent value with strong finishing capability. Makino differentiates with ArcFree arc prevention, SGF flushing, and the broadest model range. Price-wise, Makino tends to carry a premium. The best choice depends on specific application requirements, service support, and existing shop infrastructure.
