This section presents research on KEYENCE Corporation, a company engaged in the development of various measuring machines and FA sensors. We have compiled the features and functions of their representative series of three-dimensional measuring machines. Additionally, the company's approach to its business and initiatives is also introduced.
This handheld CMM is portable and can be used anywhere. The user simply places the machine on a table and uses the image navigator to confirm the measurement point.
This CMM can achieve a repeatability accuracy of ±3 μm through the use of a handheld probe. While some conventional CMMs require users to learn how to operate them, KEYENCE's CMMs can be operated intuitively, like using a hand tool such as a vernier caliper. This makes them a good choice for first-time users.
The CM Series can be used in a variety of ways to suit the needs of the work environment. In addition to measuring on a target stage, the measurement head can be attached to a dedicated pole or tripod and used to make measurements in a manner similar to taking photos with a standard camera.
The reference camera can accurately capture the rotation of the target in all directions, enabling high-precision measurement. The CMM also includes support functions, such as a color map function that compares the measurement results to 3D CAD data, and statistical analysis functions.
KEYENCE's WM series is a CMM developed for the measurement of large products and devices. Despite its compact design, it has a maximum measurement range of 15m. This enables the measurement of large parts and products that are difficult to measure with bridge-type CMMs.
The CMM can be transported in a dedicated case, making it easy to take to the measurement location. After setting up the CMM by pressing the button on the probe, the user can start measuring without having to perform any tedious setup tasks.
After measurement, the user can display the measurement results in a color map and export them to a data file. The measurement data can also be automatically converted into a inspection report, eliminating the need for manual labor.
KEYENCE, a technology-driven Japanese manufacturer, was founded in 1974. The company primarily develops and manufactures sensors, measuring instruments, image processing equipment, and control and measurement instruments. It was listed on the first section of the Tokyo and Osaka Stock Exchanges in 1990 and moved to the Prime Market of the Tokyo Stock Exchange in 2022.
In line with the company's basic philosophy of "continued creation of products with high added value," 70% of its new products are world or Japan firsts. KEYENCE is recognized as a leading company in the global market for its constant innovation and new market development.
KEYENCE's ability to continuously create new value is rooted its employee behavior guidelines and corporate culture. The company has three pillars:
KEYENCE has expanded to 46 countries and 240 locations (as of November 2023) and has established service and support systems in each region. The company is maintaining a high level of service by training local staff and collaborating with local equipment manufacturers.
Outside of Japan, it is not uncommon for products or parts to take time to arrive. However, KEYENCE has a same-day shipping system for support and replacement machines, and all products are shipped free of charge. The company also offers free loan of test machines.
KEYENCE's CMMs are designed to be compact and easy to use for anyone, anywhere. The company's focus on understanding the needs of the field and their target markets has led to the development of products that are well-suited for companies and facilities with limited space, staff, or time.
Therefore, KEYENCE's CMMs are recommended for companies and facilities that:
KEYENCE also offers a comprehensive support system that makes it easy for companies to get started with their CMMs.

This CMM has a caliper-like feel, enabling even beginners to perform high-precision measurements. It can be carried without the need for temperature control, allowing for immediate measurements at any desired location and time. As it doesn't require a large installation space, it's a CMM with a low entry barrier.
