    Lilley lights-up with Citizen

    As manufacturers of the ‘LILLEY’ range of brass lamp holders, Birmingham based S. Lilley & Son is a company of remarkable pedigree. Founded in 1840 to produce components for the rail industry, S. Lilley became one of the worlds’ first manufacturers of brass lamp holders and lighting accessories soon after. More than 160 years later,  the company is still in the ownership of the founding family, which is now the UK’s leading manufacturer of lamp holders and components for the lighting industry.

     

    With the business now in its sixth generation, Craig Lilley says: “When the company first started, it was mainly parts of the railway industry and then it progressed to parts for crystal radio sets and then with the advent of electricity, we moved into medical parts such as lamp holders and associated parts. This brings us to the present day business.” The modern face of the company undertakes general subcontract work as well as producing parts for its LILLEY lighting range.

    The onset of CNC machine tools has enabled S. Lilley & Son to advance its subcontract machining work as well as reduce the cycle times on lighting products. The company makes more than 4 million lighting parts per annum with subcontract components added to this total; something that Citizen Machinery has a considerable input toward with its five machines on site.

    Some of the Citizen machines on-site include an A20, L32, a Miyano BNA42-MSY and of course the latest acquisition, a second Miyano BNA42-MSY. Discussing why the company invested in this latest machine, Craig Lilley continues: “We bought the machine because we needed a larger capacity machine to replace an existing single-spindle auto machine that we had. The Miyano allows us to manufacture the parts that the previous machine used to produce. It also gives us the flexibility to do subcontract work, as well as machine several other parts and accessories in our lighting range.”

    The Miyano BNA42-MSY has replaced three ageing machines at S. Lilley & Son. “The Miyano BNA42-MSY gives us the automatic ability of the bar changer, so we don’t have to manually replace the bars. It also gives us the ability to run production overnight, or at least into the night unmanned.”

    Looking closer at the work envelope of the new Miyano BNA42-MSY, Craig Lilley says: “The machine has main and sub-spindle as well as a Y-axis on the turret that allows overlap machining. This gives us a lot of flexibility with the parts we produce. This gives us the facility for superimposed machining, so we can do machining with the single turret on the main and sub-spindle at the same time.”

    Alluding to how the company programs the parts on the Miyano BNA42-MSY, Craig Lilley says: “We are fortunate, as we already have a Miyano BNA42-MSY, so we have a number of programs from that machine where we can cherry-pick parts of programs from and then use on the new machine. This is very simple to do and we find the Mitsubishi control very easy to use.”

    Taking a closer look at the cutting tool strategies at S. Lilley & Son, Craig Lilley continues: “There was a lot of tooling on the old single spindle auto machines that we still used. So, we had to resurrect these tools to use on the new machine. This older tooling that has been in use for a long time on our products works as good as new tooling, we just had to resurrect it for use on the new machine. For example, we have an old-style knurling box that is used for a lot of the parts that we still have in our range. It fits on the Miyano machine perfectly.”

    Principally making lamp holders on the machines at S. Lilley & Son, Craig states: “We have an E27 lamp holder and all of the parts for that are made here. We also have an E14 and B22 that are all parts manufactured here in Birmingham. As well as turning, we need to notch the internals of the parts to locate a ceramic interior and a plastic insulation sleeve, as these parts are not allowed to rotate within the bodywork. To support this, we have to broach some notches into the bodywork of the parts to prevent rotation.”

    Concluding on the footprint of the machine, Craig says: “We are somewhat limited for space here and for a 42mm capacity machine, I think the Miyano has quite a small footprint. For us, it was essential to choose a machine that would fit within the floor area we had available. An added plus for us is that we already had one of these machines on-site, so it made sense to get another machine as we already had the crossover of skill sets on-site.”
