David Sparkes Posted December 6, 2014 Share Posted December 6, 2014 Congratulations - 2 1/2 years eh! You must have looked at a lot of frogs before finding your princess. Is that a Dealer photo, or 'as delivered' to your place? Regards. Quote Link to comment Share on other sites More sharing options...

CwazyWabbit Posted December 7, 2014 Share Posted December 7, 2014 Variable Frequency Drive, runs 3 phase from single phase and allows the frequency of the mains to be altered from 0.1hz to 400hz (usually) as well. If you change the mains frequency supplied to an induction motor you will change the speed it runs at, so it gives you a lot more speed ranges than you have using standard mains frequency. Don't expect a normal induction motor to be happy at 400hz but you will probably get away with running it at between 25hz and 90hz. Most modern ones will do more than just that though, you'll get DC braking, controlled acelleration/decelleration, fault protection, reverse, jog,current monitoring ..... and quite a few more I can't remember. Currently there are some cheap chinese ones on ebay for about £70, they seem to work ok .... proper ones are a couple of hundred quid depending on power required.

zim Posted December 7, 2014 Share Posted December 7, 2014 As above, not sure on the 400 Hz part - mine go from 0 to 50. Also offer a lot of protection to the motor as it trips out before frying the motor. Currently run 1 on the lathe and 2 on the mill.

Hybrid_From_Hell Posted December 7, 2014 Author Share Posted December 7, 2014 Hmmmmm.... Well 1st to sort out the workshop ......... Then mount the convertor and start it up.....

CwazyWabbit Posted December 7, 2014 Share Posted December 7, 2014 VFD's are great for allowing you to change speed whilst in the middle of cutting to get rid of a harmonic/chatter PS. Looking forward to seeing your tooling gloat pictures Quote Link to comment Share on other sites More sharing options...
steve b Posted December 7, 2014 Share Posted December 7, 2014 The collets give a much more accurate run out tolerance/repeatablility gripping the workpiece better than even the best 3 jaw chuck , and will hold tight without marking the surface too. With good tight bed and cross-slide ways internal/external cylindrical grinding (with the appropriate head attachment) can be carried out too A nice bit of kit Nige , worth the wait cheers Steveb Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted December 7, 2014 Author Share Posted December 7, 2014 Love it !Powered it up and after some "WTFing" sorted out the operations. Didn't know it had power feeds on both axsis Yummmmmm and compared to the Boxford, which has done me well for years, this feels like its hewn from solid steel, beautifull feel, and feels grunty powerfull as hell, the boxford I guess was a biggesh "Hobby" lathe, where as this is a smallish "Industrial Lathe" and boy there is a world of difference !! So,.........help ....... I have a box of about 20x of these thingys in various sizes, guessing they are some form of collect, but no holder, can anyone advise what they are / for / holder / will they fit my Lathe ! He is a bit of a squirrel, he had no idea what they were / from / for - but said he just got them with some other stuff !??? Glasses are for size guide as its so bad in the workshop all 8 tape measures have vanished ..Nige Quote Link to comment Share on other sites More sharing options...
ejparrott Posted December 7, 2014 Share Posted December 7, 2014 VFD and collets are brilliant. Can't really tell what collet that is from the photo. As said, they'll hold a part very accurately. I normally use them to hold the first side of a job when I turn them round to do the second end, but also if you're using 'size' bar and you need a hole exactly in the middle or you need to turn a feature on the end exactly true to it. normal 3-jaw chuck jaws rarely run anything like true, unless you have a precision chuck or use soft jaws which you bore every time you use them.

simonr Posted December 7, 2014 Share Posted December 7, 2014 I have a P&B 'Ultra Precision' chuck. It's very good - however, I enquired about some new hard jaws as the ends of mine are quite worn - and the cost was £1500 just for one set of internal Jaws! I decided I could live with the worn ones! I really ought to buy a collet chuck instead. Si Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted December 8, 2014 Author Share Posted December 8, 2014 Yaay. ...lathe in bolted to floor level. ... Powered up.... Just need to gave final er tidy up having made room for it. .. Eeek lol Quote Link to comment Share on other sites More sharing options...
sean f Posted December 9, 2014 Share Posted December 9, 2014 Good buy!, I have an M300 in the garage which I got on recomedation from a friend slightly bigger than the 250 but doesnt make much difference for most things I do. I got it wired up with a digital converter from drivesdirect who I found helpful, if not cheap, they can operate variable speed if connected direct to the motor but I bought a larger size (needed for the start up surge) and wired it to the lathes normal power supply so all the lathes normal controls and cut outs still work, I am sure this can and has been achieved by someone with sufficient electrical knowledge running variable speed but not me. The other advantage I can now run converter as a 3phase 415v ring main if I wanted to power different things provided I only run one at a time so can upgrade the mill to a bridgeport later if I want.

Nige That collet looks to be a watch makers collet. 5C collets are what you want with the appropriate chuck on its own camlock or its own dedicated set of soft jaws in the 3 jaw. Not the clearest picture but this is a gearbox layshaft held in a 5C collet chuck: https://www.facebook.com/photo.php?fbid=1289707235185&set=a.1015788867397.3820.1005341141&type=3&theater You lot seem to underrate the 3 jaw....
