Precision CNC Die Sinker EDM Machine

The CNC850 Precision CNC Die Sinker EDM Machine is designed for medium-to-large mold cavity machining, precision tooling and complex conductive metal components requiring CNC-controlled EDM processing.

With an 850 mm X-axis travel, 500 mm Y-axis travel, 400 mm Z-axis travel, and a maximum workpiece capacity of 3000 kg, the CNC850 provides the working space and load capacity required for larger mold components while maintaining stable CNC-controlled machining.

Its rigid box-type machine structure, precision motion components and intelligent EDM control system make the CNC850 suitable for mold manufacturers that require reliable cavity machining from rough processing through to micro-finishing.

850 × 500 × 400 mm Axis Travel

The CNC850 provides:

• X-axis travel: 850 mm
• Y-axis travel: 500 mm
• Z-axis travel: 400 mm

This machining range makes the machine suitable for larger cavity structures, mold inserts and tooling components that require more travel than compact EDM models.

1150 × 600 mm Worktable

The 1150 × 600 mm worktable provides sufficient space for positioning medium-to-large molds and fixtures.

Combined with a working slot size of 1800 × 1100 × 570 mm, the CNC850 provides flexible setup space for demanding mold machining applications.

3000 kg Workpiece Capacity

The CNC850 supports workpieces weighing up to 3000 kg.

This makes it suitable for:

• Large mold bases
• Heavy mold components
• Die casting molds
• Industrial tooling
• Large precision fixtures

180 kg Electrode Capacity

The maximum electrode weight is 180 kg, allowing the machine to accommodate larger electrodes required for deeper or broader cavity machining.

This is particularly useful for medium-to-large mold manufacturing.

The CNC850 adopts a fixed worktable and full box-type machine frame with dense multi-rib reinforcement.

The structure is designed to provide:

• High rigidity
• Reduced deformation under load
• Stable long-term machining
• Reliable precision retention

For a machine capable of carrying workpieces up to 3000 kg, structural stability is especially important during long EDM cycles.

The X, Y and Z axes use imported linear guide rails.

The machine also incorporates:

• Taiwan HIWIN ball screws
• Japanese NSK precision bearings
• Panasonic full-digital AC servo system and motors

These components support smooth axis movement and reliable positioning during CNC EDM machining.

The CNC850 simplifies parameter setup for different mold machining requirements.

Operators can input:

• Workpiece material
• Machining area
• Machining depth
• Required surface roughness

The CNC system automatically calculates suitable machining parameters and manages the processing cycle from rough machining to micro-finishing.

This helps reduce manual parameter adjustment and makes production more consistent.

The CNC power supply adopts EDM discharge and CNC control technology designed for stable machining performance.

Key electrical components use internationally recognized brands, while other components are selected with emphasis on reliability and long service life.

The system supports:

• Stable electrical discharge
• Automated machining control
• Consistent EDM processing
• Long-term production operation

The CNC850 Precision CNC Die Sinker EDM Machine is suitable for:

Mold Cavity Machining

• Injection mold cavities
• Die casting molds
• Large mold inserts
• Deep cavity structures

Precision Tooling

• Tooling components
• Precision inserts
• Dies
• Fixtures

Heavy Mold Components

With a maximum workpiece capacity of 3000 kg, the CNC850 is suitable for heavier molds that require both larger working space and stable EDM processing.

Complex Internal Profiles

EDM machining is suitable for complex cavities and internal features where conventional cutting tools may have limited accessibility.

The CNC850 is positioned between smaller CNC EDM machines and very large-format models, providing a practical combination of working space, load capacity and CNC automation.

Its key advantages include:

• 850 mm X-axis travel
• 1150 × 600 mm worktable
• 3000 kg maximum workpiece capacity
• 180 kg maximum electrode capacity
• Rigid full box-type structure
• Imported linear guide rails
• HIWIN ball screws
• NSK precision bearings
• Panasonic full-digital AC servo control
• Automatic machining parameter calculation
• Rough-to-micro-finishing CNC machining cycle

For manufacturers processing medium-to-large molds, these features provide a strong balance between machining capacity and CNC-controlled production.

The CNC850 is particularly suitable when a smaller EDM machine no longer provides sufficient workpiece capacity, but an extra-large EDM platform is unnecessary.

Its 1800 × 1100 × 570 mm working slot and 3000 kg workpiece capacity make it suitable for larger mold projects while retaining practical workshop usability.

This makes the machine suitable for:

• Mold manufacturers
• Die casting mold factories
• Automotive tooling suppliers
• Precision machining companies
• Industrial tooling manufacturers
