A Brief History of the Micrometer Part VI: The Future of Micrometers

This article is based on an original publication by Mitutoyo.

A Revolutionary Advancement in Micrometer Technology

The core element of magnification for all micrometers is the same: screw threads transform linear displacements into larger areas, as indicated by the thimble. Thread accuracy is representative of overall micrometer accuracy.

Introduced in 2007, the Mitutoyo QuantuMike is based on a 2mm thread pitch, a configuration which moves four times faster than traditional micrometer designs. Engineered for unsurpassed performance, this innovative tool represents a quantum leap in micrometer technology.

Pioneering Design: 2mm Feed Per Revolution

Traditionally, micrometers require 50 revolutions per 25mm. The QuantuMike's new 2mm screw thread technology enables it to move four times as quickly. Designed for ease of operation, the QuantuMike incorporates a new disc encoder technology for higher resolution along with a host of additional features:

  • Repeatable Measure: With a patented ratchet thimble mechanism, the QuantuMike helps ensure repeatable results by transmitting micro-vibrations along the spindle to the contact face. This ensures consistent measurement and good contact with the object. Working from a thimble as well as the speeder, the ratchet easily performs one-handed measurements and the speeder provides rapid spindle feed for measurement of various dimensions.
  • Function Lock Helps Prevent Error: Designed to prevent the origin point from being inadvertently moved during the measurement process, QuantuMike features an innovative function lock design.
  • Dust/Water Resistance with IP65 Protection Level: A breakthrough in the evolving history of micrometers, the QuantuMike offers excellent resistance against oil, water and dust. It can even be used with applications involving coolants and other fluids. Engineered for performance that exceeds industry expectations, this next-generation micrometer represents the future of cutting edge technology.
