Based on their operation styles, CMMs are divided into "manual-method" and "CNC (Computer Numerical Control)-method" machines. Manual-method CMMs are operated by hand using controllers or other devices.
Here, we will introduce manual-method CMMs from various manufacturers. If you are considering the implementation of a manual-method CMM, this information will be useful for you.
Mitutoyo's Crysta-Plus M500/700 series was designed as a high-precision manual coordinate measuring machine easy to use in manufacturing settings. It guarantees an error of indication of E=(3.5+4.5L/1000) μm. The knobs located on the front of the body allow for clamping in the X, Y, and Z axes, facilitating precise positioning for measurements. It maintains stable precision even in unstable temperature environments like workshop floors, with its temperature compensation function covering a wide range from 16°C to 26°C.
Considering that many users attach a centering microscope, the Crysta-Plus M500/700 series features a fine feed system for X and Y axis adjustments in one location, significantly improving operability. Optional lighting systems can be attached to the end of the Z-axis. These meticulously designed features precisely meet user needs.
Especially suited for process control at production sites and other locations, it allows real-time monitoring of measurement results and detects abnormalities in work processes, preventing the production of defective products. The Crysta-Plus M500/700 series offers flexibility under a wide range of temperature conditions and supports workpiece diagrams, catering to user requirements.
This series, combines usability with high precision in a manual-method CMM, supporting quality control in manufacturing processes and further strengthening Mitutoyo's leadership in manual CMMs.
The ALPHA series from Hexagon Metrology is a flexible CMM suitable for dimensional measurement of large cast iron and machined parts. By equipping it with an 3D scanning laser head and a continuous servo wrist, it can quickly measure complex contour shapes (optional). A bellows cover can also be added, enabling the CMM to operate even in dirty environments. There are two versions: ALPHA Classic and ALPHA Performance.

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.

A CNC CMM that was first developed in 1976.
It features applications that respond to the demand for "Smart Factories" by allowing monitoring of operational status and maintenance management of the machine through the network.
