What Mill?

Hi all.

I am new to the world of model engineering.

I wish to ask a question, though i feel it as probably been asked a thousand times. I need a small bench top milling machine like the Chester Cobra, Amadeal X12-300 Axminster etc; the choice is bewildering.

Has anyone got any thoughts as to which machine they can recommend? i eventually intend to convert it to CNC.

Regards

Ray

Hi Ray

I have the Chester Cobra. I bought this on a limited budget...

Get ready to spend a lot more than the cost of the mill on the bits needed to "Play"

So the more you spend on the mill will make the bit's seem cheaper

I'm not into cnc make enough mistakes at the moment, but if I was to go that route would buy one that was cnc.

If you do go with the Cobra try and get them to throw in a extra control box my one now has a mind of it's own

Cheers VC

Hi Ray

I bought the axminster version about 10 years ago, and found the length of the table a bit restrictive, so i bought the long table and leadscrew from Arc Euro. I dont know if they still sell these as an "add on", but they sell the same machine with the long table allready fitted (super X1L). The only problem i have had with the machine is a stripped gear,through being a bit to ambitious with a job. New gear was a few quid, and no more problems since. I now have a Chester Champion 20V,but i still use the X1L quite a lot for the smaller jobs, and would not want to part with it.

Cheers Derek

As I have said before, in a reply to a similar question elsewhere on this forum, I bought an XJ12-300 mill from Amadeal some while ago. It cost £412. I reckon that I've spent at least that again on mills, vice, centring kit, collet set and last month, a three-axis DRO set from Arc Eurotrade. Nearly finished fitting it, but have yet to use it "in anger". I'm very pleased with my mill - it does exactly what I want it to do - and that's all you can ask of any machine. Who wouldn't like a Bridgeport or similar, but not everybody can accommodate such a machine in their workshop. I would say, look at all the machines in your price range - let's face it, that's the real deciding factor - and plump for one or the other. Choose the one that best suits your specific requirements. Best of luck!

Think about exactly what you want to do with it. Is your interest in CNC a specific need for mass production or just because it looks interesting and you like computers / electronics? I assume you have a lathe so how much milling have you done with that? If you hold fire for 6 months while reading all of the ten years of ME online you will learn so much the you will know the answer yourself and save far more than th subscription.

The machines you mention both have swivel base columns by the looks of things. That will be a devil to align and you will never use it. Even a swivel head is problematic. Think on the basis that if it can be adjusted it means it will go out of adjustment and need regular work. Round columns are a problem too.

Tooling doesn't have to be a burden. Drill chuck tends to come free. All you need is 1 morse collet say 12mm and 2 end mills both 12mm. One is for Sunday Best ie brass and the other you can ruin on steel and practice.

Hi David,

To insert a hyperlink, type your message, highlight a suitable word as a keyword, then add the link as normal while the keyword is highlighted. It will then be attached to the keyword, like this. You can also set a new target i.e. a new tab or window.

If you discount machines with round columns, tilting slides & swivelling heads you will not find a lot of choice !

I noticed a small ad in the latest issue of MEW for an Axminster 6 speed milling machine (in Derby, I think) - IIRC, these are Taiwanese clones of the Emco FB2 & Axminster marketed them as the "VHM", as the head can be swivelled to place the spindle horizontal for more machining options - the column also rotates in the base to give even more options. It has a 24" by 6" table, with 15" by 5 1/2" travels - 2MT spindle in a quill with 1 5/8" stroke and 6 geared speeds - around 14" maximum clearance between spindle & table - these are compact machines but with a reasonable capacity. Look up the FB2 on the lathes.co.uk site - the clones are all but identical.

While this is a round column mill, it has a full length key to maintain head alignment. It is also swivelling head (as above), but my similar machine is no great problem to align & it doesn't seem move out of position under reasonable machining loads. If I could find any shortcoming, it is the lack of fine feed to the quill. I have an Emco brochure for their original machine which gives the weight as 110kg - the column & head removes easily from the base as a unit, and I could move each part on my own (with a bit of puffing & grunting !).

Get in quick while it's still available !

Hi There

This looks a nice mill (I have seen a photo) only been used for clockmaking.

regards David

ive got the one from machine mart - micro mill.fine for one off small jobs but not suited to anything big. nylon gears constantly shear when warm and electronics burned out long ago. table needs constant adjustment and head flexes. mine is only accurate to 7 thou on a good day.

Thanks Terry,

I knew it must be something like that. I should know not to post when the smaller end of our family is making a distracting cacophony!
