4.2. Mounting the Probe
Mount the MMP25 probe into your machine's spindle or tool holder. Ensure a firm and stable connection to prevent any movement during operation that could affect measurement accuracy.
5. Operating Instructions
The MMP25 3D Photoelectric Edge Detector is used to precisely locate workpiece edges and surfaces. Its operation relies on detecting contact with the workpiece.
5.1. Basic Usage
- Preparation: Ensure the workpiece is securely clamped on the machine table.
- Probe Positioning: Based on the position of the workpiece to be measured, move the probe towards the workpiece.
- Approach: Approach the workpiece in a step-by-step manner. The probe will trigger upon contact, signaling the exact position.
- Measurement: The machine's control system will register the contact point, allowing for precise edge detection, center finding, or Z-axis height measurement.

5.2. Z-axis Measurement
The MMP25 offers enhanced Z-axis measurement capabilities. When performing Z-axis measurements, carefully lower the probe until it makes contact with the surface. The precise trigger mechanism ensures accurate height detection.
5.3. Material Compatibility
Unlike traditional conductive probes, the MMP25 can measure non-conductive materials such as bakelite, wood, and various plastics, in addition to metals. This broadens its application range significantly.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your MMP25 Touch Probe.
- Cleaning: Regularly clean the probe tip and body with a soft, lint-free cloth. Avoid abrasive cleaners or solvents that could damage the probe's surface or internal components.
- Storage: When not in use, store the probe in a clean, dry environment, preferably in its original packaging or a protective case, to prevent dust accumulation and physical damage.
- Battery Replacement: Replace the 14250 3.6V Lithium Battery as needed to ensure consistent performance. Low battery can affect trigger reliability.
- Inspection: Periodically inspect the probe for any signs of wear, damage, or loose connections. Address any issues promptly.
