CNC Vertical Machining Center EV Series
The HIRUNG EV Series is a range of CNC vertical machining centers designed for precision milling, drilling, tapping, boring and multi-process machining.
With X-axis travel covering approximately 600 mm to 1800 mm, the EV Series provides machine sizes for compact parts, medium-sized production workpieces and larger components.
Depending on the selected model and configuration, EV Series machines can be equipped with different spindle speeds, spindle tapers, tool magazines, CNC control systems, chip management systems and rotary-axis solutions.
Instead of selecting a VMC only by machine size, HIRUNG can recommend a configuration according to your workpiece dimensions, required machining processes, fixture space, accuracy and production requirements.
Choose the Right EV Series Vertical Machining Center
The EV Series covers different machining envelopes, table capacities and spindle configurations for different production requirements.
EV640L / EV855L
These models are suitable for small to medium-sized workpieces where compact machine size, fast movement and efficient machining are important.
Typical applications can include:
- Precision machined components
- Small plates and housings
- Fixtures
- Tooling components
- Small mold components
- Repeated production parts
The EV640L and EV855L provide compact VMC solutions while maintaining the basic structure and automatic machining functions required for production use.
EV1060L / EV1165L / EV1270L / EV1370L
These models provide larger X/Y/Z travel and table capacity for manufacturers machining medium-sized workpieces.
They are suitable when production requires a balance of:
- Larger machining envelope
- Increased table capacity
- Stable cutting performance
- Multi-operation machining
- More fixture space
These models provide greater flexibility for general machining, mold work, fixtures and industrial components.
EV1580 / EV1890
For larger and heavier components, the EV1580 and EV1890 provide increased axis travel and table capacity. According to the documented EV Series parameter range, the larger machines extend X-axis travel up to 1800 mm and table load capacity up to 2000 kg, providing additional machining space for larger fixtures and workpieces.
How to Choose a CNC Vertical Machining Center
The right CNC vertical machining center should match the actual workpiece and machining process rather than simply providing the largest possible travel.
X / Y / Z Axis Travel
Start with the maximum workpiece dimensions and the actual machining area required. The machine travel should also provide sufficient room for:
- Fixtures
- Vises
- Tool clearance
- Rotary tables
- Multiple-part setups
Table Size and Load Capacity
Machine travel alone does not determine whether a VMC can handle the workpiece. Check both the table dimensions and maximum table load, especially when machining:
- Larger fixtures
- Mold plates
- Multiple parts in one setup
- Heavy workpieces
Accuracy and Production Requirements
For precision and repeated production, machine selection should also consider:
- Positioning performance
- Repeatability
- Machine rigidity
- Thermal stability
- Fixture design
- Tooling strategy
Spindle Speed and Cutting Requirement
Different machining processes require different spindle characteristics.
Higher-speed spindle configurations can support applications where cutting speed and finishing performance are important, while heavier cutting places greater emphasis on spindle power, torque and machine rigidity.
4-Axis or 5-Axis Requirement
If a workpiece requires machining on multiple faces, angled features or complex surfaces, a rotary table can reduce repeated repositioning.
Selected EV Series machines can be configured with 4-axis or 5-axis rotary tables, depending on machine size and workpiece requirements.
Tool Capacity
Parts requiring several milling, drilling, tapping and boring operations benefit from an automatic tool changer that reduces manual tool changes between processes.
