Sieg X2 Mini-Mill Teardown
Couldn't resist taking it apart when it arrived as everything was badly set up and these Chinese tools arrive covered in nasty red shipping grease.
It gives me a chance to spread some rustproofing grease on the back of the iron castings too. Note that both the X and Y feed screws are bone dry! Argh...the Chinese have discovered woodruff keys! I wanted to pack the X feedscrew housing with grease so this came off too. This is the gib strip for the X feed and is clearly in need of lapping - probably the greatest problem of Chinese tools. Needless to say I forgot to photograph the lapped strips! I reckon on about an hour for the longer Y strip and 30 mins for this shorter one. I go in sanding the strip back and forth with 120 Wet/dry on a glass plate. Then I proceed to 240, 400, then 1200 until the surface is super smooth. Some people go further and polish them but fine scratches are fine by me as I reckon they hold lube better. This is what really lets down Chinese tools - note that this X feed screw retaining nut has already been adjusted twice before I got near it! I reckon the machines are set up in the factory and then semi-stripped to repaint them in the specific dealer colours. No wonder I thought the X feed was out of adjustment! I've not done the vertical feed gib strip as I didn't fancy taking the head off just yet - and it's bloomin heavy. I did remove the head stop, raise the head and spray white lithium grease over all the gearbox internals for good measure and I tweaked the motor to gearbox fit to quiet down transmission noise. It's all back together, and after a 10 min 0 - max rpm run in (not mentioned in the manual but recommended for the lathes using the same gearbox) it's running lovely! |

Re: Sieg X2 Mini-Mill Teardown
great to see some pics of the machine. Typical chinese quality but whatever you can get a decent machine out of it if you spend some time on cleaning and adjusting!

Re: Sieg X2 Mini-Mill Teardown
cinqster,
Any plans to cnc this mill. I have had my eyes on one of these for a while but am getting my lathe first. I want to use them both for modelling but I also have a race car so want to make sure it is suitable for both and not too small. |

There are some good conversion kits around and some good user sites if you need more info. My first tweak will be a belt drive conversion as these beasts are notorious for breaking the plastic teeth if a tool stalls. The lathe first is a good idea - I've already had to use mine to turn parts just to install the rotary table on the mill - yep, I've fallen into that model engineers trap from the get-go! More on the install later. |
