As domestic CNC control systems continue to advance, many reliable and easy-to-use solutions have become available for modern press brake applications. In this guide, we will introduce Techmation SCS700, the new standard CNC system equipped on LIANGJI electro-hydraulic CNC press brakes.

Techmation SCS700 is a highly functional and cost-effective control system that combines key advantages of Delem DA53TX and Cybelec CT12. With strong overall capability, intuitive operation, and practical bending functions, it provides an efficient solution for precision sheet metal processing.

1. Advanced Y1/Y2 Closed-Loop Control: Eradicating Angle Deviations

The foundational engineering advantage of an Electro-Hydraulic CNC Press Brake is its ability to govern the left and right hydraulic cylinders independently via proportional valves. However, maintaining perfect parallelism under intense tonnage or off-center loads requires millisecond-level processing.

The Techmation SCS700 acts as the ultimate supervisor for this hydraulic balance:

• Real-Time Linear Encoder Feedback: The system continuously reads data from the machine’s scales to monitor the precise positions of the Y1 and Y2 axes.
• Velocity Closed-Loop Control: It delivers precision closed-loop control over the proportional valves, adjusting oil flow on-the-fly to correct misalignment.
• Parallelism Safety Guardrails: According to the machine parameter settings, if the deviation between Y1 and Y2 exceeds the “Y Tilt Allow” threshold (typically set up to 10.00 mm for safety limits), the system instantly triggers an alarm to protect your Electro-Hydraulic CNC Press Brake frame from structural twisting.

2. Multi-Axis Backgauge Mastery (Standard 6+1, Expandable to 8+1)

A premium Electro-Hydraulic CNC Press Brake relies heavily on its backgauge to execute intricate, multi-step sheet metal profiles without manual resetting. The SCS700 natively supports a wide array of motorized axes to automate backstop manipulation:

• X-Axis Depth Control: Automatically calculates the precise horizontal positioning based on whether the user selects “Internal Dimension” or “External Dimension” in the step editor.
• R-Axis Vertical Tracking: Automatically adjusts the height of the backstop fingers to perfectly align with the top edge of varying die V-openings.
• Z1/Z2 Lateral Positioning: Calculates symmetrical or custom asymmetrical finger offsets parallel to the die, perfectly adapting to variable sheet widths.
• The Palletizing Mode (Holding Material): For exceptionally long sheets prone to downward bending under gravity, the SCS700 calculates specialized X and R trajectories so the backgauge fingers act as a forward-holding support platform.
• Intelligent Retract Functionality: To eliminate material jamming or severe collision risks as the upper punch deforms the metal, the system commands the X-axis to retreat a relative distance the moment the ram hits the “clamping point”.

3. Simplified Tooling and the Interactive Mold Library

As showcased in SCS700, rapid tooling changes are vital for reducing machine idle time. The Techmation SCS700 features dedicated, comprehensive libraries for Punches, Dies, and Materials:

• Punch and Die Library: Operators can create, edit, store, and read custom tool geometry. Input parameters include tool height, width, angle, radius, and safety ranges.
• Material Compensation Profiles: The Material Library stores structural variables like tensile strength (Rm) and elasticity (E) for various metals (such as STAINLESS, SPCC, AL, or ZINC).
• Semi-Automated Tool Setting (CAL Pinch & CAL MaxOpen): Installing new tooling on an Electro-Hydraulic CNC Press Brake can be tedious. The SCS700 offers a dedicated “Tool Setting” interface. Using a hand crank wheel at a safe “low speed” gear, the operator lowers the punch until it safely contacts the die and applies a pre-set calibration tonnage. The system captures this exact reference point instantly, automatically establishing the software’s lower dead center (BDC).

4. Advanced Bending Modes: Free, Bottoming, Flattening & Large Arcs

An industrial-grade Electro-Hydraulic CNC Press Brake must be highly versatile. The Techmation SCS700 processing screen allows operators to seamlessly toggle between distinct bending methodologies within a single program:

Free Bending (Air Bending)

The system automatically calculates the required penetration depth of the Y-axis to achieve target angles, factoring in material springback based on the selected die V-opening.

Pressed Bottom Bending & Flattening

For specialized profiles requiring sharp coining or total flattening (hemming), the controller commands the ram to descend to the absolute bottom of the die or the pressure plate point, minus sheet thickness, allowing precise manual correction values (Corr).

The Large Arc Bending Feature

Instead of relying on guesswork for radius bending, the SCS700 includes a dedicated “Arc” editing suite. By simply entering the chord length (D), target angle, radius (R), and desired bending pitch, the system calculates the exact number of hits and incremental X/Y positions required. It even supports continuous foot-pedal processing so the Electro-Hydraulic CNC Press Brake operates fluidly without cycle interruption.

5. Proactive Process Commissioning & Troubleshooting

Even on a top-tier Electro-Hydraulic CNC Press Brake, variations in sheet metal batches can cause angle drift. The Techmation SCS700 resolves this through advanced software tuning and transparent error mapping:

• Three-Point Process Commissioning: If a new batch of material shows poor angular consistency, operators can execute a commissioning cycle by bending three separate test angles (ideally wide intervals like 100°, 135°, and 170°. By inputting the actual measured outcomes and clicking “Auto Adj”, the system reconstructs the angle-to-depth calculation curve for flawless long-term accuracy.
• Granular Error Codes for Instant Diagnostic: Rather than halting without explanation, the SCS700 logs and actively maps faults to precise mechanical or software origins. For example, Err14 indicates a Y-axis tilt anomaly, Err21 flags a collision risk in backstop settings, and Err34 warns that a soft limit has been reached. This ensures your Electro-Hydraulic CNC Press Brake experiences minimal downtime.

6. Industry 4.0 Readiness and Production Management

Beyond machine control, the SCS700 positions your Electro-Hydraulic CNC Press Brake for modern smart factory integration. The system includes a robust “Production Record” module that tracks production plans, positive or negative part counting, and logs good versus defective numbers. With full Ethernet connectivity, custom IP configurations, and cloud platform tracking compatibility, managers can remotely analyze yield rates, calculate OEE, and synchronize live workshop data to master screens.

Conclusion

Investing in a high-caliber Electro-Hydraulic CNC Press Brake is a major capital commitment. To maximize the return on that investment, the machine must be paired with a controller capable of micro-second hydraulic precision and macro-level process automation.

The Techmation SCS700 provides exactly that—making it the ultimate control choice for next-generation sheet metal processing. Whether you are a machine builder looking to empower your hardware, or an end-user seeking flawless accuracy, the SCS700 ensures your Electro-Hydraulic CNC Press Brake runs faster, smarter, and with absolute precision
