Milling Machines

Hi Alan, maybe not, but I've been told by my boss not to spend too much time or get too fussy with jobs as the customers do not what to pay much, they just want it to work.

Regards Nick.

This is just a general post, not a reply to anyone or directed at anyone.

I'm curious as to the checking of the current machines, which are all usually Chinese, for what is commonly referred to as "Fit for Purpose " [ F f P ]

My curiosity causes me to question if this has gone on from say WWII which will encompass most present users.

The reason being that in this time there have been good and bad made. The 'bad' being the made to a price machines that are in direct comparison to todays Chinese Machines. I think we can include machines such as the Winfield, Pooles, Gamages and the like, not totally rubbish but certainly cut corners so the firm could continue to exist.

In the good section we can include the likes of Myford, Raglan, Tom Senior and a few more.

I don't think anyone will take exception to this loose bundle of machines.

Now I can't recall any posts in ME where the owner used to term F f P or even did a series of test on one. Todays buyers will go out and buy a Tom Senior, post how good it is and everyone should buy one [ Not going to happen, not enough left ] but never tram the column and report on it.

Hi Steve

Sorry you've not hit it off with Ketan. I bought my X3 and my KX3 from him with no regrets. On my last visit he didn't want to sell me an ER11 collet chuck because he did't think it would be fit for the purpose I was going to use it (he hasn't seen my work) but it did the job I wanted. When I am looking to buy something I look on his website first.

This is just to give you some balance from an ARC customer.

Cheers Michael

Just curious here, but I have just been looking through the ISO Standards for milling machines {ISO 1984-2:2001} manually controlled, table of fixed height, vertical spindle. And am curious as to whether the Chinese hobby machines have to adhere to these standards, or because they are for hobby use if the standards do not apply. I am sure that there is somebody on this forum who would be able to answer this.

Regards,

Donald.

A propos John's comments: I think your generalisations are correct. What intrigues me is that when I was looking for a first lathe in 1980ish there were none of the British entry level lathes available from new and yet the far east hadn't really penetrated the market. It would seem that during the 70s the model engineer made do with second hand or bought a Myford (or possibly a Boxford). It would be interesting, if I had the data, to compare the costs relative to the average wage of lathes in each of the decades since the war to the present. I'm sure we would find that today's model engineer is very spoiled compared with his (or hers, Jo) forbears.

I seem to remember Tubal Cain reviewing a Senior E mill in ME when he bought one. I can't remember if the column was out of true though.

Cheers, Rod

Donald,

Few standards (for anything) are compulsory in any legal sense - though of course if the manufacturer claims the product complies with a particular standard then it should do so. Being for hobby use doesn't make any difference.

David, Thanks for clearing that up. I think that 1 that would have to be adhered to [in Europe] would be the CE standard. I would think they would all meet that, It's just that I was curious about the mechanical standards.

Regards,

Donald.

Ketan Swali is gettin here so much undeserved flak that I'll prefer to order some next tools from him. I just have to salute that level of comitment and integrity he is showing.

Have to get some stuf together at the work, that I will be blamed anyways no matter what, but someone has to do the work, othervice the rest would have nothing to complain about.

CE is not a standard - the CE mark is supposed to indicate that the equipment complies with all relevant EU Directives (low volatage, machinery, EMC,...). These typically relate to basic EU wide 'safety' requirements and are rarely anything to do with performance or capability of the equipment.

There is a useful summary of "CE marking" on the hse website.

The final bullet point might be worth further investigation !

I may have missed it in the fire fight, but what the hell machine did the guy who started the war actually buy in the end?

I think he got fed up with the whole thing and took up cross stitch.

.

Yabut how do you get two loose needles to be in tolerance ?

Francis, John I think you have first to define cross stitch, then decide the tolerance and fit of the cross and the stitch, and that is before we get to decide whether the cross and/or the stitch individually and/or combined are fit for purpose. Will the cross and the stitch even fit if they are both from China and what will happen if they are of mixed race?

Am I being silly now? Probably, now where is that corkscrew?

Donald its only relevant to the better companies who will want to flaunt it. If a company doesnt state ISO 1984-2:2001 it stands a very good chance it hasnt been tested and therefore pot luck what you end up wth.

Quite right as well David J i have a certain 3ph inverter that hasnt a CE mark or British Standard on it, neither had the two previous.

Roderik a 92 Harrison VS330 was $20500 plus extras a lot dearer than an equivalent Colchester.

A 1992 TOS 380 was £5400 fully loaded and delivered.

By fully loaded I mean 6" 3 jaw, 8" 3 jaw, 8" 4 jaw, faceplate, catchplate, 5C chuck, all change wheels for special threads, 3 tailstock chucks, fixed and revolving centres. Two speed motor, fixed and travelling staedies.

Spare clutch plates, spare cross slide nut, spare clutch selector, spare drive belts, spare brake pad.

Funnly enough the EXACT same price as a Myford 254 with no chucks, accesories or delivery.

There's a cure for the problem, someone has just got to start building lathes and,or milling machines of a modern design, of reasonable quality, and cheaper than the imported machines. His staff will of course be volunteers, and first class craftsmen,yea right, dream on. Ian S C

TOS, I think, were Czech. Hardly fair to compare the cost of a communist subsidised product with Myford. Looking for model engineers' lathes, the only new models available, AFIR, were Myford, EMCO and the hobbymat from East Germany. I don't know how the price of an EMCO 8 compared with a Myford 7 or EMCO 5 with an ML10.

Hi there

Time to call a halt to this I think.
