4. Persediaan dan Pemasangan
4.1 Mounting the DRO
- Select a suitable location on your machine (lathe or mill) that provides clear visibility and easy access to the keypad.
- Use the provided mounting bracket and hardware to securely attach the DRO display. Ensure it is stable and free from vibration.
4.2 Sambungan Elektrik
- Sambungan Kuasa: Connect the provided power cable to the AC 80-260V input port on the rear of the DRO. Plug the other end into a compatible power outlet.
- Axis Connections: Connect your linear scales (X, Y, Z axes) to the corresponding DB9 TTL signal input ports on the rear of the DRO. Ensure each scale is connected to its correct axis port.
- Sambungan Pilihan: If applicable, connect EDM and RS232 cables to their respective ports.
After all connections are made, switch on the power using the ON/OFF switch located on the rear panel.
5. Arahan Operasi
The SNS-3V DRO offers a comprehensive set of functions for precise machining operations. Familiarize yourself with the keypad layout and the following functions:
5.1 Operasi Asas
- Zero Point Clear: Press the '0' button for the desired axis to set the current position as zero.
- Tetapkan semula: Resets all axis readings to zero.
- Millimeter/Inch Switching: Toggle between metric (mm) and imperial (inch) units using the 'MM/INCH' button.
- Absolute/Incremental Coordinate Conversion: Switch between absolute (ABS) and incremental (INC) measurement modes. Absolute mode measures from a fixed origin, while incremental mode measures from the last set zero point.
5.2 Fungsi Lanjutan
- 200 Groups of Sub-Datums: The system can store and recall up to 200 sub-datum points, allowing for complex part setups and quick transitions between different reference points.
- Memori Matikan: The DRO retains its last settings and coordinate values even after power is turned off, ensuring continuity of work.
- 1/2 Center Function: Quickly find the center point of a workpiece or feature.
- Linear Error Compensation: Compensates for minor inaccuracies in linear scales, improving overall measurement precision.
- Fungsi Kalkulator: Perform basic arithmetic calculations directly on the DRO.
- Radius/Diameter Function: Easily switch between displaying radius and diameter values, particularly useful for lathe operations.
5.3 Machining Specific Functions
- Circular Drilling: Assists in drilling patterns on a circular path.
- Oblique Drilling: Guides drilling operations along an angled line.
- Chamfer Processing: Facilitates the creation of chamfers.
- Arc Processing: Supports machining along an arc path.
- Lathe Function (Matching): Specific functions optimized for lathe operations.
- Rectangular Hole Step-by-Step Processing: Aids in creating rectangular holes with precise step movements.
5.4 Precision Enhancements
- Digital Filtering: Reduces signal noise for more stable readings.
- Vibration Filtering: Minimizes the impact of machine vibrations on measurements.
6. Penyelenggaraan
- Pembersihan: Regularly wipe the display and keypad with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Keadaan Persekitaran: Ensure the DRO is operated within its specified temperature and humidity ranges. Protect it from direct sunlight and excessive heat.
- Pemeriksaan Kabel: Periksa semua kabel secara berkala untuk tanda-tanda haus atau kerosakan. Gantikan sebarang kabel yang rosak dengan segera.
7. Penyelesaian masalah
7.1 Isu dan Penyelesaian Biasa
- Tiada Paparan/Kuasa:
- Check if the power cable is securely connected to both the DRO and the power outlet.
- Verify that the power switch on the rear panel is in the 'ON' position.
- Pastikan salur keluar kuasa berfungsi.
- Bacaan yang salah:
- Check all linear scale connections to ensure they are secure and connected to the correct axis port.
- Verify that the linear scales are clean and free from debris.
- Ensure the correct resolution and compensation settings are applied in the DRO's configuration (refer to the full operation manual for advanced settings).
- Pad kekunci Tidak Menjawab:
- Restart the DRO by turning it off and on.
- Ensure no foreign objects are lodged under the buttons.
