Overview
The Sodick AZ275Nano is a premium sinker EDM machine from Sodick’s AZ Nano series, combining linear motor drive technology with nano-level discharge control for ultra-precision cavity machining. The AZ275Nano targets the most demanding sinker EDM applications where surface finish quality, electrode wear rates, and dimensional accuracy must meet specifications measured in single-digit micrometers and nanometer-level surface texture.
The machine features X/Y/Z travel of 275 x 200 x 200 mm (10.8 x 7.9 x 7.9 in) with Sodick’s linear motor drives on all axes. The linear motor architecture eliminates the backlash and friction inherent in ballscrew-driven sinker EDM machines, providing sub-micron electrode positioning accuracy that is critical when burning cavities with wall thicknesses below 0.1 mm and feature tolerances in the 2-5 micrometer range.
The Nano designation refers to Sodick’s nano-pulse generator technology, which controls discharge energy at the nanosecond level. This ultra-fine pulse control produces significantly thinner heat-affected zones and re-cast layers compared to conventional sinker EDM generators, resulting in better surface integrity and reduced post-EDM polishing requirements. Combined with Sodick’s PIKA mirror finish option, the AZ275Nano can achieve Ra 0.05 micrometer (2 microinch) surface finishes directly from the EDM process.
The work tank accommodates workpieces up to 400 kg on a 450 x 300 mm (17.7 x 11.8 in) table. The Sodick LN2W intelligent CNC control manages all aspects of the sinker EDM process including adaptive gap monitoring, automatic orbit pattern generation, and multi-electrode sequence programming. The machine weighs approximately 3,200 kg (7,055 lb) and is widely used in Japanese precision connector mold shops, optical component tooling, and medical device mold production. New machines price between $200,000 and $350,000.

Strengths & Limitations
Strengths
- Nano-pulse generator controls discharge energy at the nanosecond level, producing minimal re-cast layer and heat-affected zone for superior surface integrity
- Linear motor drives on all axes eliminate backlash for sub-micron electrode positioning critical to micro-cavity and thin-wall EDM applications
- PIKA mirror finish option achieves Ra 0.05 micrometer surface finishes directly from the EDM process, reducing or eliminating post-EDM polishing
- Compact 275 x 200 mm travel envelope is optimized for precision connector molds, optical tooling, and medical device components where micro-scale accuracy matters most
- LN2W intelligent CNC with adaptive gap monitoring automatically adjusts discharge parameters to prevent arcing and electrode damage during unattended operation
- Proven platform in Japanese precision mold production with extensive track record in connector, optical, and micro-mold applications
Limitations
- 275 x 200 mm travel limits workpiece size to small-to-medium mold inserts, not suitable for large cavity or multi-cavity mold work
- Nano-pulse generator and linear motor technology command a significant price premium over conventional sinker EDM machines at similar travel sizes
- PIKA mirror finish capability requires careful electrode preparation, multi-stage burn sequences, and operator experience to achieve consistent results
- Specialized Sodick service and electrode programming expertise is required for optimal results, limiting the machine to shops with access to trained personnel

Frequently Asked Questions
01
New Sodick AZ275Nano machines typically price between $200,000 and $350,000 depending on the PIKA option, electrode changer configuration, and accessories. The nano-pulse generator and linear motor technology account for the premium over conventional sinker EDM machines with similar travel dimensions.
02
The AZ Nano series uses a nano-pulse generator that controls discharge energy at the nanosecond level, versus microsecond-level control on standard machines. This produces thinner re-cast layers, better surface integrity, and finer surface finishes. The AZ Nano also uses linear motors on all axes versus ballscrews on some standard models.
03
PIKA (meaning glitter in Japanese) is Sodick’s ultra-fine surface finishing generator option that uses extremely low-energy, high-frequency discharges to achieve Ra 0.05 micrometer mirror finishes on cavity surfaces. This capability is most valuable for optical mold inserts, cosmetic consumer product cavities, and lens tooling where mechanical polishing would distort fine features.
04
The AG55L offers a larger work envelope (550 x 350 mm travel) and higher workpiece weight capacity (700 kg) with the LN2 generator. The AZ275Nano has a smaller envelope but uses the more advanced nano-pulse generator for superior surface quality and re-cast layer control. Choose the AG55L for general-purpose precision sinker EDM work; choose the AZ275Nano when surface integrity and micro-precision are the primary requirements.
