LK Metrology has been at the forefront of metrology advancements, achieving numerous industry-first milestones:
Founded by Norman Key, a former Rolls-Royce engineer, LK (formerly named as LK Tool) were a supplier of granite inspection tooling and inspection components to the engineering industry.
The name LK was formed by using the initials of Jim Lowther, his father-in-law and owner of Notsa Engineering, and Normans surname, Key.
The first LK Maxi-Check manual CMM was supplied to Rolls-Royce Bristol.
LK continued to expand the size of Coordinate Measuring Machines and became the first manufacturer to offer a system complete with mini-computer and in-house written inspection software.
LK worked in partnership with Rolls-Royce developing the now industry standard Renishaw Touch-Trigger Probe.
Norman Key worked with the Chairman of Renishaw, Dave McMurtry and ordered the first 10 probes to fit to the Maxi-Check CMM replacing the original solid probes. Notice how these first probes carried the LK logo.
After the move to its current Derby site, LK purchased the company Control Systems from Rolls-Royce.
First Motorised/CNC Maxi Check CMM
The first motorised or CNC Maxi-Check machine was supplied to LK’s first overseas customer in Sweden.
LK manufactured the world’s largest moving bridge co-ordinate measuring machine to inspect Mini Metro bodies at Rover Longbridge, England. Interestingly, this machine is still used to inspect car bodies to this day after many upgrades.
LK designed and developed the world’s first horizontal spindled CMM named Metre 4. This machine incorporated a granite spindle. The first machine was sold to Rolls-Royce Hucknall in Nottinghamshire, England.
The ‘little brother’ to the LK Metre 4, the LK Micro 4 was introduced. The first machine was infact manufactured by Leicester based, British United Shoe Machine Co. Ltd.
LK manufactured the world’s first bridge machine incorporating all granite slideways. Replacing the Maxi-Check, the Granite 80 (or G80 as it was called) stayed in manufacture until it was superseded by firstly the ‘G80HA’ and then the ‘Axiom’ range some 12 years later.
A large all granite bridge style CMM was sold to I.U.G in Romania with a measuring volume of 9m x 3m x 2m.
This granite table was so large, two individual tables had to be mated and epoxy bonded together using a special LK developed process.
LK introduced another world’s first, the Carbon Fibre spindled Micro 4. This high accuracy horizontal arm machine was ideal for car body measurement.
The Micro 4 was redesigned incorporating all granite slideways and all air-bearing construction.
LK moved into the American market with the formation of LK Tool USA Inc. initially based in Chicago and then moving on to Phoenix.
A second USA location was opened in 1983 in Flint, Michigan to service the Automotive Industry.
The Ford Motor Company ordered two high speed ‘Twin Column’ Micro 4 CMM’s with automated part loading systems.
LK were chosen as a preferred supplier of coordinate measuring machines for General Motors. Over 50 machines were supplied between 1984 and 1987.
Boeing ordered the world’s largest twin-bridge machine for the measurement of 747 wing structures. This machine, being too large for manufacture in-house, was built at the British Rail Engineering workshops in Derby.
Following continuing success in the world market, LK were awarded the Queen’s Award for Export.
Again, LK were leading the world with it’s use of materials technology and the Axiom range of ceramic spindle machines were introduced.
Another first for LK: the CF90 machine range was introduced. This machine was designed as a truly thermally stable machine utilising Ceramic, Invar and Carbon Fibre in its construction.
The first two machines were sold to GM in Buick City and Hamtrack in the USA. This machine was designed and developed to meet the GM specification for speed, accuracy and shop-floor use.
With the Aerospace Industry using more carbon fibre components, LK introduced the Ultrasonic NDT inspection machines to test for de-lamination.
The re-designed Micro/Metre 4 horizontal arm machines, re-named the HC90, were introduced with a four column machine installed at Rover Longbridge in Birmingham, England.
In the same year, LK Tool USA Inc were relocated in a new facility in Brighton, Michigan.
The Axiom range of bridge machines were re-designed with ceramic beam and spindle components and introduced as the G-90C range.
Another first for LK, the G90K was redesigned using an ‘H’ section ceramic beam and ceramic spindle.
The manufacturing process for the bridge utilised specialist bonding technology for the assembly of the beam.
The first machine was supplied to Argentina (Fric Rot Automotive) and now LK’s global presence covers 37 countries.
Automation reached new heights with the installation of five fully integrated FMS CMM’s in CDC.
LK world support continued to grow with the opening of the LK Hong Kong office.
CMM programming was revolutionised with the use of CAD data. LK introduced the first release of the now world famous CAMIO software incorporating full DMIS support.
Based upon Spatial Technologies ACIS solid modelling kernel, CAMIO software offered both on-line and off-line programming capability.
Increasing the machine portfolio, LK introduced the Ultra range of high accuracy bridge machines. The Ultra offered standards room accuracy at a reduced cost.
Introducing yet another machine range, the LY90S Layout style of horizontal arm machines was released.
Machine controllers form an important part of the measuring system. The advent of continuous contact probing led LK to introduce the LK4000 controller. Controlling up to 9 axis, the LK4000 supported a new range of analogue probes from Renishaw.
After 5 years of continuous growth in the CAMIO software, a new product CAMIO Studio-Inspect introduced a new user-friendly interface with enhanced programming capability. This software paved the way for future-proofing the inspection software from LK.
LK celebrated 40 years of metrology expertise.
Incorporating all this knowledge into the machine design saw the bridge range of machines improved and the Evolution and Integra machines were born, both offering an unprecedented 10 year structural guarantee.
Land Rover placed an order for 14 car body machines for the quality control of the new Discovery.
LK form a joint venture with Chinese company SMTC to produce CMM machines in China.
Shanghai Measuring and Cutting Tool Works begin to produce the LK G-90C range and also the new granite based LK Ascent.
LK enter the automotive powertrain market to compete against Zeiss and the fixed probe.
Primarily designed for the USA market, the PT Scan machine was an evolution of the Ultra offering high-speed analogue scanning, but with volumetric accuracy as low as 1.4+L/500.
LK Libero replaces the PT Scan offering improved accuracy, repeatability and speed performance for powertrain measurement
LK supply, what is still thought to be at 6m, one of the widest CMM ever manufactured. With a working volume of 6m x 6m x 3m, this massive CMM still manages to achieve accuracies of less than 5 microns due entirely to the design and ceramic material technology that has been the trademark of LK for over 20 years.
LK CAMIO software enters into its 7th generation of development. With full simulation, collision detection and multi-sensor support, CAMIO is proving to be the forerunner in multi-sensor DMIS programming
The LK Altera replaces the small volume Integra model. With a major re-design incorporating improved performance, productivity and reliability, the Altera is the first fully Nikon branded CMM.
The LK brand reaches 50 years of age. After 50 years of development, the LK CMM has come a long way since the early days of fixed probe and solid granite construction.
LK controllers update to the latest electronics with the introduction of the NMC300 and the NMC100
LK Altera CMM machines are selected by American aircraft engine manufacturer for turbine blade inspection.
