Digital micrometer provides measuring speed boost

Mitutoyo (UK) product story

The QuantuMike combines a precision 2mm-pitch leadscrew with a high-resolution electromagnetic induction rotary encoder to increase adjustment speed by up to four times.
Mitutoyo has released the QuantuMike digital micrometer.
Conventional digital micrometer leadscrews need a fine pitch, typically 0.5mm, to give enough mechanical magnification for the miniature rotary encoder on the spindle to achieve the required resolution.
This makes the micrometer slow to adjust when taking measurements and checking the origin point.
This can be frustrating for the user and is a factor that limits measurement efficiency.
QuantuMike overcomes this limitation by combining a precision 2mm-pitch leadscrew with a high-resolution electromagnetic induction rotary encoder to increase adjustment speed by up to four times, giving the user a much better measurement experience and enabling a real increase in productivity.
Although productivity gains depend heavily on the type of measurements made and their spacing within the measurement range, the results of tests on a stepped shaft showed that QuantuMike measured this workpiece 2.4 times faster than a standard digital micrometer.
As well as its exceptional speed, QuantuMike offers a number of key features including excellent resistance against oil, water and dust.
With an IP65 protection level, this product can be safely used in machining situations that include splashing coolant fluid.
The ratchet thimble mechanism helps ensure repeatable results by transmitting microvibrations along the spindle to the contact face to provide a constant measuring force and encourage good contact with the workpiece.
The ratchet works from the thimble as well as the speeder so it is always easy to use - even when making measurements one-handed.
The sound of the ratchet provides the user with a sense of confidence and the speeder enables the rapid spindle feed needed when measuring widely different dimensions.
Measurements are made to an accuracy of +/-2um throughout the range.
0-25 and 25-50mm models are available, both with and without data output.
