Recently, various manufacturers have started selling user-friendly and space-saving types of CMMs in addition to more traditional bridge-type machines.
While larger CMMs require ample space for installation, this is not a concern with compact types. For instance, KEYENCE's XM and WM Series are handheld CMMs. Measurements can be easily performed with a small camera and a handheld probe. Since these machines are compact, they can be used for measurements anytime, anywhere.
Below, we will introduce a compilation of CMMs that can be used without taking up much space. If you are thinking about introducing a compact measuring machine or already have a bridge-type machine and want something more convenient, be sure to check them out.
KEYENCE's XM Series is a compact-sized CMM that can be installed in various locations. With excellent environmental resistance, it can achieve high-precision measurements within a temperature range of 10-35°C and a humidity range of 20-80%.
Because of these features, a dedicated measurement room is not necessary. The XM series can be brought to the site to perform on-machine measurements while keeping large workpieces fixed in place. Additionally, it is suitable for measurements in small spaces such as offices rooms. The camera unit can be detached from the installation stand, allowing for versatile use in various situations, such as placing it on a surface plate or tripod or conducting measurements with the handheld probe while the machine is on the ground.
Despite its compact design, the XM Series boasts high performance. It achieves high-precision measurements with a repeatability of ±3μm by adopting a unique structure that consistently captures the workpiece at the center of the lens.
The WM Series by KEYENCE is a portable CMM that can be carried in a dedicated suitcase. Despite its compact size, it can measure large workpieces up to a maximum size of 15m. The built-in camera of the main unit constantly tracks the position and orientation of the handheld probe, instantly recognizing the location even if the operator moves around. This feature allows for easy measurements of large-sized workpieces by a single person without the need to move the object being measured.
No dedicated measurement room is required, and measurements can be taken immediately on-site. With the use of an elevating tripod, it can handle workpieces with varying heights.
This versatility makes it suitable for a wide range of measurement scenarios, including dimension and strain measurements for sheet and plate work, adjustment and post-assembly measurements of equipment, shape measurements of pressed products, confirmation of cast product replacements, on-site surveys, and sketching of maintenance parts.
The WM series significantly streamlines the measurement and adjustment of large welded products and similar tasks that traditionally required the use of tape majors or large calipers and a team of 2-3 people.
One notable type among compact and portable CMMs is the handheld-type. Handheld-type machines use a handheld probe to take measurements by making contact with the target object. Their significant advantage lies in their compact and lightweight design, allowing for convenient measurements anytime, anywhere. Moreover, because measurement locations are indicated by image navigation, it is easy to make high-precision measurements even without specialized skills or expertise.
With excellent environmental resistance, there's no need for a clean and temperature-controlled measurement room. You can bring the machine to various locations, placing it on a surface plate, on the floor, or on a machine tool.
Handheld-type CMMs excel in measuring objects with sizes or complex shapes that were challenging for arm-type or bridge-type CMMs with fixed ranges. Their initial cost is relatively low, and as they don't have any moving parts, they require minimal maintenance and no running costs.
Handheld CMMs combine compactness, lightness, and user-friendly operation, allowing for easy measurements anywhere. Because they can be used intuitively, they can be effortlessly used by workers who have no experience with CMMs but with vernier calipers or micrometers.
Moreover, due to their reasonable prices, Handheld CMMs are a good option to minimize initial costs. The handheld device can be brought to manufacturing or work sites for measurements - there is no need for a dedicated space for a bridge-type machine.
The key aspect of a compact and space-efficient CMM lies in its high versatility, allowing usage in various locations. The ability to measure large-sized workpieces without moving them significantly enhances measurement efficiency, particularly when conducted by a single person.
Consider factors such as the machine's performance, including accuracy and broad measurement range, as well as beginner-friendlyness when selecting a device that meets the needs of your specific work environment. This site provides recommendations for CMMs that are easy to use and offer high versatility, addressing various challenges in different work scenarios. Please feel free to explore our suggestions.
