Accutex DS-2H CNC Die Sinker Series

Twin-Head and Single-Head Large-Frame CNC Die Sinkers for High-Throughput Cavity Machining

The Accutex DS-2H Series consists of large-frame CNC die sinking EDM machines available in both twin-head (2H) and single-head (SM) configurations. These machines are engineered for mold makers, aerospace tool builders, and industrial manufacturers who require high-accuracy cavity machining on large workpieces, long travel requirements, and the option to dramatically reduce cycle time using dual-ram EDM processing.

Twin-head models feature two independently controlled rams operating inside the same dielectric tank, enabling parallel machining of two cavities, synchronized burning on the same mold, or rough/finish operations performed simultaneously. Single-head SM versions use the same machine platform but provide double the X-axis travel of their twin-head counterparts, giving shops greater flexibility when machining oversized mold bases, long electrodes, or wide-format tooling.

Travel ranges span from 430mm to 1275mm per ram (860mm to 2550mm on SM single-head models), all with 1000mm Y-axis and 600mm Z-axis travel. With table load capacities from 11,000–19,000 kg, the DS-2H Series supports large molds, multi-cavity tools, aerospace dies, and deep 3D cavity structures where rigidity and accuracy are essential.

Key Features

  • Twin-head 2H configuration with two fully independent rams, ballscrews, and servo control channels.
  • Single-head SM configuration with double X-axis travel, ideal for long or wide-format workpieces.
  • Moving-column architecture increases rigidity and stability during heavy or long-duration burning cycles.
  • X-axis travel ranges:
    • Twin-head 2H: 430mm, 775mm, 1075mm, 1275mm
    • Single-head SM: 860mm, 1550mm, 2150mm, 2550mm
  • Y-axis travel: 1000mm
  • Z-axis travel: 600mm
  • Large table sizes up to 3100 × 1100 mm for multi-cavity and large-format tooling.
  • Exceptional load capacity from 11,000–19,000 kg to support oversized molds and aerospace dies.
  • High dielectric tank capacities (3410L to 5910L) stabilize long dual-ram operations.
  • 500 kg electrode weight capacity per ram for large graphite and copper electrodes.
  • Advanced dual-channel CNC control supports independent ram programming, coordinated motion, orbiting, and multi-step burn routines.

Benefits for Metal Cutting Manufacturers

  • Twin-head 2H models allow two cavities—or two areas of a single mold—to be machined at the same time, significantly reducing total EDM time.
  • Independent Z-axis control supports parallel roughing/finishing, cavity duplication, and two-electrode burn strategies.
  • Single-head SM models provide extended X-axis travel for larger molds and long-format tooling on the same rigid platform.
  • High rigidity under load ensures consistent burn quality on large mold bases and aerospace tools.
  • Large workpiece capacity up to 19,000 kg supports major tooling plates, dies, and complex multi-level molds.
  • Thermally stable dual-ram machining provides predictable geometry and uniform electrode wear.
  • Floor space efficiency—one twin-head machine replaces two separate EDMs.
  • Lower total tooling lead time for manufacturers who must deliver molds, dies, and large tools on compressed schedules.

Ideal Cutting Applications

  • Multi-cavity mold production requiring simultaneous cavity burning
  • Large mold bases requiring two active EDM rams to reduce lead time
  • Aerospace tooling such as layup molds, trim dies, and composite forms
  • Deep, complex ribs and tall core features requiring parallel rough/finish EDM
  • Long-format industrial tooling using extended-travel single-head SM models
  • Precision duplication of molds for high-volume injection molding

Production Line Automation & Integration using Accutex’s Manufacturing Execution System (MES)

Accutex’s MES platform brings smart manufacturing capabilities directly to the DS-2H Series, providing real-time visibility and centralized control across multi-machine production environments. The system monitors utilization rates, machine status, and active machining processes, while also managing electrode libraries, workpiece tracking, tooling inventories, and mass-production counts — all from a single interface.

RFID integration is central to how MES manages tooling and scheduling. Each tagged tool can be inserted in any position, with the system automatically scanning, identifying, and sorting tools according to programmed priorities and operational sequences. In robotic cell configurations, this eliminates manual sorting and reduces the risk of loading errors across extended unmanned runs.
