A CMM is a device that measures the three-dimensional coordinates of an object, allowing for the measurement of three-dimensional shapes such as contours, dimensions, and spatial relationships of various components. While they are all categorized as CMMs, different machines have different features, making it crucial to choose a machine that suits your company's needs.
Here, we classify CMMs into four groups based on their features and showcase products from different manufacturers for each of those groups. If you are considering implementation, please feel free to refer to this information.
Traditional CMMs pose various challenges such as the need to control the temperature and humidity of the measuring environment. Due to this, they often require personnel with specialized knowledge. However, in recent years, CMMs that are easy to use even for beginners have been introduced to the market.
On this page, we showcase CMMs with user-friendly interfaces that are easy to handle, especially for beginners. You can check out detailed information about their features and specifications.
In recent years, easy-to-handle compact CMMs have benn gathering attention. Handheld devices like Keyence's XM Series and WM Series allow measurements from various angles using wireless probes. Since there is no need for a dedicated measurement room, measurements can be taken anytime, anywhere.
On this page, we compile information about compact and space-saving CMMs. If you are considering introducing a compact measuring machine, be sure to have a look.
Portable CMMs offer the advantage of free approach to the workpiece and the ability to measure large workpieces by a single person. Since measurements can be taken directly on-site, portable CMMs reduce the effort and time required for transporting or moving the workpieces.
Recent years have seen the introduction of easily portable CMMs, such as Keyence's WM Series. If you are facing challenges with measuring large workpieces, consider opting for a portable solution.
The increasing demand for high-quality products has led to a surge in the need for high-accuracy CMMs. While the typical accuracy of a CMM is around 1 μm with a contact probe and approximately 10 μm when using non-contact measuring methods, recent models can achieve measurements with an accuracy of up to 0.1 μm.
As CMMs become more accurate, they enable higher-level reverse engineering and quality control.
On the page below, we present a compilation of high-accuracy CMMs. If you are considering the adoption of a high-accuracy measurement device, be sure to check it out.
Laser Coordinate Measuring Machines (Laser CMMs), also known as 3D Scanning CMMs, offer a powerful blend of accuracy, speed, and versatility. Unlike traditional CMMs that use a touch probe, laser CMMs perform non-contact measurements by capturing millions of data points to generate detailed 3D models. This makes them ideal for inspecting complex or delicate parts, as well as for reverse engineering and digital archiving.
Laser CMMs are widely used in industries like aerospace, automotive, and heavy machinery, where precision and efficiency are essential. While slightly less accurate than tactile CMMs, their ability to scan full surfaces quickly makes them a practical solution for most applications. Portable models even allow on-site measurement, reducing downtime and improving workflow.
By combining rapid data capture with flexible usability, Laser CMMs have become an essential tool in modern quality control and metrology.
