    My Mazak QT-10 w/T-Plus started doing that same exact thing it was the control power supply going south.

    Thanks will, I enjoyed your thread.
    "Shop progress report from Will of GB" would have been a good title.so could be found for a search

    Well it has been busy these last few months, a lot on and never enough time. One of our main customer bases is historic race cars. Normally we get a bunch of broken or worn out parts and have to re engineer them back to their original state. This was a fun one, the back vertical bulkhead and engine mount off a Brabham BT49. No drawings available only the original cracked part. Spent half a day measuring it up on the CMM and drawing it, it was then machined in three operations out of solid.

    A new equipment day, well new to us. In order to run the laser with have to hold a number of 15 cylinder banks for nitrogen and oxygen purge gasses. Over the last few years this keeps adding up, combine it with the fact the supplier has reduced their delivery days to our area from 4 days a week to now Tuesdays we can find ourselves running out of gas. We either have to rent extra banks of gas which I guess the supplier is wanting us to do or the options we went with.

    A set of three maxigas nitrogen generators, tanks and high pressure generators.

    First generator installed and being tested.
    We aim to get 99.99% pure nitrogen from these.

    Interesting.

    So - is there an expected payback on the investment, or is it about the same cost with more independence as the main benefit?

    Yes to both really. Being only able to get gas one day a week from a major supplier is ridiculous so this gives us independence as you say, it also fixes our running costs.

    The generators use pressure swing adsorption technology, this works by separating nitrogen molecules from the oxygen molecules within the compressed air. Pressure Swing Adsorption does this by trapping oxygen from the compressed air stream using adsorption. Adsorption takes place when molecules bind themselves to an adsorbent, in this case the oxygen molecules attach to a carbon molecular sieve. This happens in two separate pressure vessels, each filled with a CMS, that switch between the separation process and the regeneration process.

    Each generator uses about 40CFM which generates into the bank of white tanks this then passes through a HP compressor which takes it up to 35bar. The laser requires 20 bar of pressure. As our compressors run all day the generation cost will hardly register, the only increase will be running the HP compressor. At our current rate of gas usage we calculated that the set will pay for it's self in a year and a half. The laser currently runs 4-5 hours each day after set ups and material changes etc. Even if we were to run for double that time the system has enough generation capacity to keep up. The biggest savings is when cutting thick stainless and aluminium (10mm - 20mm)as the pressures and flow rates consume gas at a alarming rate and quite often makes these types of jobs expensive (We can use a 15 bottle 300bar bank in an hour) . Generating our own supply should make these jobs more competitive.
