Help, New ARC Sieg SX2.7 mill reverse???

Hi all, my new Sieg SX2.7 from Arceurotrade arrived this morning, spent a couple of hours unboxing, taking the column off, moving it down the mancave and putting it back together, all went well.

Had a good look over it and have to say I'm very happy so far, checked the table X axis, maybe 0.005 mm end to end, less for the Y axis, (dti is only 0.01mm) all with no play as far as I could tell, table looks very good, everything moves nice and easy with only the last 10mm of X axis tight at the left end of travel.

Chuck is very stiff to remove from the spindle but the ER32 collet holder is fine.

I did remove the spring from behind the X axis handle that pops the dog clutch out as that would really annoy me also the guard as its far to big!

Run it for 10 mins each @ 500, 1000 and 2000 rpm, spindle was warm at the end but not hot.

This one has the new control panel with the speed knob, emergency stop, start and tapping mode, but nothing for reverse apart from in tapping mode with the green quill buttons, I have tried everything but cannot find how to run it in reverse unless in tapping mode, manual is for the old panel so no help at all.

Do the new ones now not run in reverse or am I being stupid?

Tried a few quick test cuts just on aluminium and all is good.

Few things it will need very soon, X powerfeed and Z powerlift, I would end up lopsided other wise winding them handles so much.

Most mills only run in one direction.

There are a few exceptions as you can get left-handed drills and mills for special purposes.

You have reached the top of the slippery, spendy slope!

A 'phone call to ARC should elicit the definitive answer to your particular query. I think Jason has one, or had one for his book, so maybe he'll chip in.

Oh yes a very slippery slope lol, going to use stepper motors for them, one more axis and it might as well be CNC!!

Will ring and ask Arc.

The push button one did do reverse and still says on the description for it.

What you really need is a good book on the subject that will tell you that on the new panelled machines "Forwards and reverse on these machines can only be operated by pressing one of the green buttons on the spider when in tapping mode"

So no high speed rev but you can make use of it for under 500rpm milling by pressing the tapping mode button on the panel and then one of the green buttons.

Also make sure you use the small stop button to stop the machine unless it's an emergency in which case hit the big red one.

I have a Warco mill with spindle reverse capability. I can't recall any time I have used that feature In the 10 years I've had it.

Yup saw that in the book I have called " Milling for beginners" written by some bloke called Jason Ballamy (whoever he is ) after I have posted and phoned lol.

Probably never need reverse but knew the old version did it.

If you build the Hemingway speed increaser then you will need it! Otherwise only useful for tapping.
