sieg kx3 cnc mill

[John S]

Not miffed at all my son, I don't sell them so no vested interest there.
Looked at the picture you posted but can't see any motors, the OP asked for CNC and in this post the Sieg KX3.

So to post back to the OP there is no reason why a KX3 cannot do what you need.
Biggest limitation on the KX3 for what you require is the Y axis travel is 150mm.
The X3 converted to CNC is 190mm in the Y axis.



This is a stainless steel loco wheel 85mm diameter, 10mm thick cut with a 4mm carbide cutter.



Batch of 12mm square lathe tools in high tensile steel.



Flywheel 80mm diameter in brass, drawn, coded and cut in 40 minutes to prove how easy the concept of CNC is.



Two housings in aluminium approx 5" x 3" for a vintage Alvis car, all CNC machined including the thread milling but not the welded bridge which was done after.



Helical gear done on the 4th axis with simple form tool.



Herringbone gear done in one pass as one piece on the 4th axis.

Kip that picture isn't an X3 SX3 or KX3, it's a special machine made for JET in the US with a sliding Y axis.

I still don't have a vested interest in the KX mills, I worked on them but don't sell them, the quoted post from Helmsworthlad was for the X3 which has actually been discontinued since the appearance of the KX series.
That part of ARC's website hasn't been updated but I am thinking about resurecting the kits as I'm getting about 2 enquiries a month.

I didn't realise that you had to be completely neutral to post on this site, after all I have seen many pointers to people making and selling things.

I haven't hid behind anything, I made it clear I worked with both Seig and ARC, perhaps that has upset some ? I don't know.

The OP, posted asking for advise, all he got to start with was abuse.
If there as anyone else on this group who can truthfully answer with practical experiance of what the poster asked then by all means let him post.
So far I haven't seen any, I was loath to at first because of my links, I even said I could be accused of being biast and instaed of saying how good / bad what features etc I posted actual parts made on one.

Although this post isn't probably relevant anymore i've just purchased a Sieg KX3 and I am really happy with it for a small mill. I purchased it second hand off ebay but it was like new. All I will say there was about 0.07mm backlash in each of the screws consecutively and the chap who had it previously hadn't compensated for that in Mach 3 and he was complaining about the finish on his parts. This was only part of the problem the machine is heavy for a small machine but if you see on the photo the guy had it on the shittiest stand imaginable which was a self build and was causing the majority of his machining issues as literally it would move everytime the machine made a cut. I am currently in the process of building a high quality enclosure and changing the standard R8 to a TTS/ Tormach Tooling System holder with Pneumatic drawbar. I will do a seperate post on that and please check out my Youtube vids.

I have a SIEG KX3 with servo motors and their PC ethernet controller - not sure if the G-code is similar to the MACH controller ones
The biggest issue is I haven't been able to sort out a post for it
I don't have sample G-code to compare with

Can anyone assist please?

For CAM software I am using BOBCAD
