Locking axis on Sieg SX2 mill

[David Brown 9Participant @davidbrown9]

I cannot figure out how to lock the x and y axis on my Sieg SX2P mini mill from Arceurotrade.

Does anyone have this machine who could let me know how to do this?

I am sure it is obvious, but the design seems a little different to some other Sieg SX2 mini mills and so googling hasn't helped so far.

isn’t by using the long socket head in centre of the X + Y gib strips ? – the Y being a right pain to reach

Well it is the method I use on mine with an appropriate Allen key….

Hi, David , I have this same mill and find the easiest way for me is to just tighten up the nut holding the adjustment handles providing you have no amount of backlash in the leadscrew this is all I ever need to do. Hope this helps.

Thanks a lot. I thought it would be obvious!

It is the socket heads, I tried tightening them before, I just wasn't tightening them enough. Now both axis lock. The Y is indeed a pain to reach!

You So make your self an extended wrench, a length of bms 1/2 in dia.

Bore to take a hex key cut down, silver solder in, cross drill and add a tommy bar….QED….

the same table is used in the ArcEuro SX1 – Graham Meek in EIM has commented on the somewhat poor gib design and suggests replacing with ones that more nearly fill the gap – I bought a 2nd SX1 to use as a base for some digital control (keeping my current working model available for making various addons) and decided to replace the gibs with somewhat wider brass being more easily obtainable, rather than Meek’s suggested cast iron, the originals being steel (which should work well on against a cast iron bed) – one of the original gibs was actually significantly banana shaped would happily spin round on a surface plate – I’d always had some problems with keeping the gibs on my original in good adjustment – easy movement in centre often resulted in too tight a movement at extreme travel whilst easing here tended to give some play in centre thus I suspect one of the gibs on my original is also banana shaped as Meek comments that only a small adjustment no more than hand tight of the centre screw should be needed to fully lock the gib
