Thread: Advice for Myford Mill
02/06/2018 19:29:36

I will have to look at fitting a new lead screw with Ball Screws, although not expensive it might be very time consuming. Funny but I did think the cutter speed should have been higher, not sure where I got the lower figure from. I do sometimes use WD40 as coolant/lubricant but haven't tried parrafin, will give that a go as well, Oh and no more climb milling, although I have always got away with it until now.

Thanks everyone,

Ian

Hi NDIY and Andrew,

Yes I was climb milling, feed rate was a bit slow as I tend to wind in a bit on the slow side, no coolant or cutting fluid in use. The tool seems to have good clean cutting edges laterally but maybe the edge on one of the ends is a little dull.

I was traversing the x axis and both y and z were locked. The vibration deffinitely seemed to be coming from play in the tables x axis. I know from hand feeding (taking out backlash as I go) that there is room for improvement but not sure on the best way to achieve this.

Thanks again for your input gents, I value your views.

Hi,

Having enjoyed using my Myford Mill for a few light jobs I recently tried taking a slightly deeper cut than I normally would. I will point out that I tend to mill only aluminium and this was the case recently.

Spindle speed was 380rpm and tool was a two flute, half inch diameter end mill, intended depth of cut was 1.5mm at 5mm wide, hand fed.

I noticed a little vibration and quickly reduced the DOC. However I am left thinking that I should service the table and try to reduce the backlash in both the x and y axis.

Does anybody have any experience of doing this with this particular machine? If so can you offer any ideas or advice please?

PS, I also think my cutter speed should have been higher ?

Thanks,

Ian

Thread: New Warco Lathe and Mill

If I am not mistaken the WM250 is essentially the same machine as my Chester DB10, and if so there is little you can do to adjust the bed as the mounting holes run laterally (along the lathes length) rather than across the lathes width which would assist in untwisting the bed should you need to.

I got around it by mounting on a very sturdy bench with a solid metal surface, luckily that was all that was need with mine to turn parallel cuts.

I was convinced I had replied to this thread, blimey this is how starts !

I live in Crewe ( believe me that aint anything to brag about now adays ) and I would love to meet up with others, that's how I learn new things. If I can help someone else then I am more than happy to do so.

If the quill's so far out front to rear, why doesn't the clock finger run off the blade in the side to side video?

Something not right here.......

17/05/2018 20:58:06

STK if the head was true to the table as you have already stated, you should not and would not have got a saw tooth cut if milling in a conventional manner. That could only happen if the head was not trammed,or if you had lowered the quill, maybe you did the cut with the quill lowered but you haven't made that clear.

If I was paying hundreds of pounds for a product with a specification, I don't think it's unreasonable to expect the product to be inside that specification, otherwise whats the point?

17/05/2018 20:43:34

mmmmm, so if (IF) the square, was true, the quill is sitting out of azimuth in both x and y axis. This should only effect drilling operations in conventional use but does show that assembly is not correct.

I cannot possibly see how this could simply be adjusted out by the owner and despite Daniels post, I don't believe anyone should accept this level of quality and fix it themselves.

Yes I tested the column to insure it was correct and it was.

I tested it by moving the whole Z axis up and down with the hand wheel I got a reading of about 0.002".

As soon as I touched the quill it went bat crazy 0.025".

I also took Warcos advice and checked the bolts that hold the head onto the column it made no difference what I did ( i had a verdict mounted to see what happend when I loosend and tightend the bolts I got no movemnt in the DTI meaning it was not that knocking it out of play if I had it to tight or to loose).

So let me get this right, the X axis was accurate (within tolerance)? also the Y axis was accurate (again within tolerance)? The z axis was accurate with head to table, however the Z axis of quill to table was not verticly true?

Is that correct?

No problem wink

Page 12, it's history now anyway, maybe time to lay this thread to bed wink

Ketan,

Possibly this chap?

17/05/2018 19:49:06

I don't agree with you David, Warco say that they have corrected the problem and that it was the operator at fault not the machine. However I can not see what the OP was doing wrong? He explained that with the head static there was no issue, however when using the quill in the Z axis, it was not running truely verticle (unless I have misunderstood?).

So how could the OP have simply dialled the movement of the quill withing the casting to correct it?

In essence I am saying that either I have completely not understood the actual nature of the problem, or Warco haven't?

About 18 months ago, I went to an engineering show/event with a view to buying a lathe. I was hoping to get more info about the warco lathes that would be at the show, but once there, the lack of help, answers or interest from the warco team on the day left me in real doubt, so I ended up buying a chester lathe (which so far has been great).

Reading this story leaves me with no doubt that I could have safely bought from warco or could buy without worry from warco in the future, they have not been very quick to respond, but they have fully honoured their obligations and you simply can't ask for more than that.

Well done Warco.

Thread: Drinking and Driving.
02/05/2018 19:49:23

Having seen how well the go soft approach has worked over the last twenty years (failed completely IMHO) I would build more prisons and fill em with drink drivers etc.

My motivation would simply be to keep scum bags away from people like me so that they can no longer inflict misery onto normal members of society, a bit harsh, yeah maybe but all this pussy footing around is an insult to anyone who has ever suffered the injustice of crime to see the offender get handed down a joke sentence.

Oh and before I end, lets remeber that everyone of the offenders chose to walk that path, they were not forced to offend.

I'm another chap that used both the ward and the herbets as an apprentice, great machines and very capable in the right hands. John Mosley, I was part trained by a chap called Herbet Mosley, very nice gent and an extremely good machinist, based in Crewe many years ago, any relation of yours?

Thread: Recommendations for a quality milling vice?
01/01/2018 15:39:45

I bought the same vice (I think) from Arc that Jason is showing, at first I had a nightmare with it, it seemed that everything mounted/gripped would lean down at the front (operator end). I suspected the moving jaw was diving as the fixed one couldnt really go anywhere.

Just to be sure I re-clocked the table, a couple of tenths at worst but not in that plane, so not that, then re-clocked the vice, emmm couldn't se anything more than about 4 tenths, so I assumed my parralells were not true, not sure why as they had been when I tested them. Anyway it turned out to be a very small ridge at the end of the vice base, directly under the fixed jaw. the machining hadn't gone in quite far enough, I milled it and stoned it and now my vice doesn't show any movement or discrepency when tested with paralells soI'm very happy with it.

Lastly cant believe the prices they are asking £2100 for cheap chinese at least 10-18 years old about that price new delivered. Similarly M300 gone through the roof as well, last 12 months £1800 - £2700 now £3 to £4.5k. Mine cost £750 8 yrs ago when generally going for £1600 - £2200, there at the right time.
Even on old worn out early L5 £1K no gearbox, i paid over the odds £900 for a 20 yr younger 140 with Norton gearbox, tooling etc who they kidding.

Yeah I think these companies, who appear to be buying up auction stuff and then trying to flog it at stupid prices, are doing Warco a huge favour, even Chester and the others are benefitting from the ridiculas prices being asked.
