Precise edge probing for fast, repeatable workpiece alignment
Edge probes and 3D probes are specialised measuring tools used on milling machines and CNC machining centres to determine the exact spatial position of workpiece edges, hole centres or reference faces and thus set the machining datum with micrometre accuracy. They serve to define the zero point for subsequent metalworking operations, reducing setup time and ensuring process-safe positioning by switching the probe into the spindle and contacting the clamped raw part either manually or automatically. Using mechanical, optical or electronic principles, these devices deliver high repeatability and rapid part detection, while advanced 3D probes, edge probes and precision probing systems minimise scrap and support consistent quality in precision CNC production.

Millimetre-accurate workpiece set-up without guesswork
A touch probe (also known as an edge finder or 3D probe) is a high-precision sensing instrument used on milling machines and CNC machining centres to determine the exact spatial position of workpiece edges, hole centres and reference faces relative to the spindle axis. Probing establishes the machine zero point with micrometre accuracy by bringing the probe into physical contact with the raw part, either manually or automatically.
How probing cuts set-up time and raises process reliability
Touch probes work by converting mechanical, optical or electronic contact into a reliable reference signal for the control system. Mechanical edge finders use a spring-mounted stylus that visibly gives when contact is made; electronic variants provide an immediate LED or electronic trigger; full 3D probes permit simultaneous, dial-indicator-supported probing in the X, Y and Z axes without spindle rotation. The result is faster, repeatable set-up, fewer scrap parts and higher machine utilisation.
Key operational benefits:
- Reduced non-productive time through automated reference detection
- Repeatable micrometre-accurate zeroing for first-pass quality
- Compatibility with manual edge finding and automated 3D probing workflows
- Versatile sensing principles: mechanical, optical, electronic
- Decreased risk of irreversible dimensional errors by precise initial referencing

FAQ
What is the difference between a touch probe and an edge finder?
An edge finder is typically a mechanical device used for manual detection of a workpiece edge; a touch probe includes electronic signalling and, in 3D variants, allows automated probing in the X, Y and Z axes. Both types are covered in the Metav range.
Can a 3D probe be used without spindle rotation?
Yes. 3D probes enable simultaneous probing in all three axes without spindle rotation, allowing faster and safer automated set-up cycles on CNC machining centres.
Which sensing principle should I choose for my application?
Select based on process requirements: mechanical edge finders for straightforward edge detection, optical or electronic probes for immediate signalling and repeatability, and 3D probes for full spatial referencing. Metav offers options across all sensing principles.
How precise is the zero-point established by a touch probe?
Probing establishes the zero-point with micrometre-level accuracy, ensuring the dimensional foundation for subsequent machining programmes.
