1. Why Machine Panels Need to Be Rethought

In CNC machinery and automation equipment environments, the operation panel is not merely a collection of buttons, but the control interface most frequently used by operators to interact with the machine. When a traditional integrated panel is still used, with the screen, buttons, handwheel, and emergency stop all fixed in a single location, operators often have to reach too far, lower their heads to read values, or turn their bodies to operate the machine. While these actions may seem acceptable in the short term, over long periods they can place cumulative strain on the shoulders, neck, wrists, and lower back, further affecting operating smoothness, judgment speed, and workforce stability. For equipment builders and procurement teams, panel design is no longer just a matter of appearance, but a key aspect of machine competitiveness directly related to efficiency, safety, and future maintenance.

2. How Separated Design Improves Ergonomics

The core of ergonomics is to make equipment conform to natural human movement. According to common ergonomic principles, display information should be positioned within an operator's natural line of sight, while frequently used controls should be arranged within the arm's natural reach. A separated design divides the panel into a main panel and a secondary panel: the main panel is responsible for status display, alarms, and primary safety functions, and is fixed at an optimal viewing height; the secondary panel integrates the handwheel, axis selection, feedrate override, or frequently used buttons, and can be positioned more conveniently based on machine layout and operating habits. This functional division reduces repetitive reaching and unnatural twisting, making operation more intuitive and better suited for long-duration work.

Practical Advantages of Separated Panels

• Frequently used operating components can be placed closer to the work point, shortening operation paths and response time.
• The clear division of functions between the main and secondary panels helps reduce accidental operation risk and improve information recognition efficiency.
• It provides greater operating flexibility in standing, seated, or multi-directional machining scenarios.
• The modular design is more favorable for maintenance, replacement, and future functional upgrades.

3. Suitable Machine Application Scenarios

Grinding machines, lathes, injection molding machines, and various types of customized automation equipment are typical examples. When operators need to observe the machining point while making fine adjustments with the handwheel or switching functions, a fixed panel often cannot accommodate both visual focus and hand movement at the same time. A separated design allows the display area to remain in the clearest position for overall monitoring, while placing the secondary panel near the tool setting area, machining area, or mold change area, so operators do not need to change posture just to reach the buttons. This design is also particularly valuable for retrofit projects involving older machines, because it can improve the actual operating experience without requiring major changes to the existing machine structure, while preserving room for future expansion.

4. Key Planning Considerations for Main and Secondary Panel Function Allocation

In practice, the main panel usually houses the industrial display, status indicators, alarm signals, and emergency stop button to ensure operators can quickly grasp machine status. The secondary panel is better suited for integrating high-frequency operating components such as the MPG electronic handwheel, rotary selector switch, feedrate override, and axis selection. If the equipment also involves coolant, lighting, tool compensation, or auxiliary controls, these can be assigned to either the main or secondary panel based on frequency of use. The real key is not simply to 'separate' the panel, but to reconfigure functions according to the operating process so that visual flow, hand movement, and safety logic are aligned with one another.

5. Evaluation Points for Buyers and Equipment Builders Before Implementation

When planning a separated panel, it is recommended to first confirm three points: first, the operator's primary standing position and most frequent movements; second, whether the available installation space, cable routing paths, and protection requirements of the machine are clearly defined; third, whether future integration of a handwheel, I/O modules, or replacement interfaces for older machines will be required. YEU-LIAN has long served customers in the machine tool and automation equipment industries, and can help plan ergonomic solutions better suited to on-site needs based on machine type, mounting hole conditions, and control requirements. For procurement personnel, choosing a separated design is not only about improving comfort, but also about reducing operator error, shortening downtime for adjustment, and preserving greater maintenance and customization flexibility for the equipment.

6. Conclusion

As machine operation evolves from simple usability toward greater emphasis on ergonomics, safety, and maintenance efficiency, separated design has become a control interface direction worth prioritizing. It enables machine operation to better align with ergonomic principles, while also giving equipment greater flexibility in actual delivery, long-term use, and future upgrades. If you are currently evaluating CNC operation panel upgrades, retrofitting older machines, or optimizing automation equipment interfaces, a separated panel is an important option that balances practicality with integration efficiency.
