LK Tool Company Limited was founded in Derby, England in 1963 by Norman Key (a former Rolls Royce engineer) and Jim Lowther (Norman’s father-in-law). It was a supplier of granite inspection tooling to the engineering industry and then became the innovator of the “Bridge Type” multi-axis Coordinate Measuring Machine. LK started operations in the USA in 1983 capturing a large part of the automotive market for high volume production inspection systems. Since then, LK has been designing, manufacturing, and deploying CMMs throughout the world.

Throughout its history, LK has been recognized as a market leader and is credited with a long list of “firsts and successes” such as:

  • First to design a Bridge Type CMM
  • First OEM to integrate a computer with a CMM
  • First to develop inspection software specifically for CMM use
  • First to use all air bearing and granite guideways for stability and stiffness
  • First to use carbon fiber composite spindles
  • First to use microprocessor controlled drive systems
  • First to produce a High Accuracy, Horizontal Spindle CMM
  • First to produce a truly thermally stable CMM
  • Worked in partnership with Rolls-Royce Ltd to develop Renishaw’s  First Touch Trigger Probe for use on a CMM.

LK is the world’s oldest manufacturer of CMM. In 2018, as LK celebrated its 55th anniversary as a leader in the CMM Industry, the company returned to be an independent UK CMM manufacturer, thanks to its acquisition byASF Metrology (Torino, Italy), under the ownership and management of Angelo Muscarella, who has a long and proven track record in metrology and especially in the CMM business.

Headquartered in Derby, LK Metrology has Sales and Support offices in the UK, North America, China, Belgium, France, Germany and Italy.

The LK brand is renowned for high quality innovative CMM products and excellent customer service serving industries such as automotive, aerospace, medical and electronics for more than 50 years.
