Whether you're outfitting a coordinate measuring machine (CMM) or expanding your metrology toolkit, our extensive range covers industry-leading probes, high-accuracy styli and all the essential accessories to ensure reliable results and repeatable measurements. With fast shipping from our UK warehouse, expert technical support and a trusted reputation among machine shops and inspection labs, we make it easy to maintain measurement integrity and boost production efficiency.
A CMM probe (Coordinate Measuring Machine probe) is a precision sensor used to accurately measure the geometry of a part by detecting specific points on its surface. It acts as the “touch” component of a CMM system, collecting data that helps verify dimensional accuracy, tolerances, and overall part quality. CMM probes come in various types (including touch-trigger probes, scanning probes, and optical or laser probes), depending on the required accuracy and application. When paired with the right CMM styli and accessories, these probes enable engineers and quality control teams to inspect components quickly and with exceptional repeatability.
A CMM probe works by detecting and recording precise points on a component’s surface as it comes into contact with, or scans, the part. When the stylus tip of the probe touches the workpiece, it sends an electrical or optical signal to the CMM, which then records the exact X, Y, and Z coordinates of that point. By collecting thousands of these measurement points, the CMM creates a detailed 3D map of the part’s surface, which is compared to the original CAD model or design specification to verify dimensions, shapes, and tolerances. Different probe technologies work in slightly different ways; for example, touch-trigger probes register a single point each time the stylus makes contact, while scanning probes continuously measure surfaces for smoother, more detailed data capture. Combined with the right CMM styli and accessories, this process allows manufacturers to achieve exceptional accuracy and consistency in quality control and inspection.
Whether you’re replacing worn components, upgrading your CMM setup, or equipping a new machine, products offered by Cutwel deliver reliability, repeatability, and accuracy for every measurement task.
Our CMM probe bodies are built for consistent performance and compatibility with leading CMM systems. They provide the essential link between your coordinate measuring machine and the stylus, ensuring precise signal transmission and stable measurement results.
Choose from a wide selection of CMM styli and probe inserts in various materials and tip configurations. From ruby ball styli for standard measurements to carbide and ceramic options for demanding applications, each stylus is engineered for durability and precision.
Enhance the flexibility and reach of your CMM setup with our range of probe and stylus accessories, designed to improve access, stability, and measurement accuracy in complex inspection tasks:
Our CMM styli starter kits offer a convenient, cost-effective solution for new setups or maintenance teams. Each kit includes a variety of stylus types and accessories to cover a wide range of inspection needs, helping you stay productive and prepared.
Ensure precision and repeatability in every measurement with our range of CMM workholding solutions. Designed to securely hold components during inspection, these fixtures minimise vibration and movement for accurate, consistent results across all measurements.
Selecting the right CMM probes, styli, and accessories is essential to achieve the highest accuracy and efficiency in your measurement process. The correct setup depends on your application, the type of parts you’re inspecting, and the level of precision required.
When it comes to CMM probes, styli and accessories, choosing the right supplier is just as important as choosing the right tools. At Cutwel, we combine technical expertise, quality products, and outstanding service to support every stage of your measurement and inspection process.
