    Default New school,new toys

    Hi Guys,
    My new school has a nice toy for me to play with.

    It looks like this one .
    https://www.machineryhouse.com.au/Pr...ockCode=M629D#

    It has yet to do a job because it would appear there are no milling cutters for it.
    It has a set of Vertex collets on a R8 taper that I have found .

    I will be looking to order the correct set of milling cutters for it. Any suggestions or ideas on the cutter set that I should buy for it?

    I thought I would do the right thing by at least doing a couple of projects on it.

    • The tailstock turret tool ,
    • A ball cutter radius tool with a indexed carbide .
    • and the slotting for sheet metal finger Bender that Simso designed and appears at the head of pages as a sticky.


    After all ,I would be expected to understand the machine before I let students loose on it.
    Thanks
    Grahame

    Are there any restrictions on the type of opperations a student can perform on the Mill.
    If you wish to cover the Basics of Mill use with the students and Finance is not really a problem would go for a suitable clamp kit to suit the Tee slots,an angle plate of substansial size to suit the table,a swivel machine vice 150/200mm,30,50 75/100 face cutter,with the smaller either 2or3 tips the 50 5or 6 tips and the 75/100 6to 10 tips.
    In regards to slot drills and end mills you decide on the smallest and go to maybe 40mm.
    A minimum 8" rotary table or universal divideing head and tailstock.
    If they will be doing advanced machineing a 75/100boring head.
    A few pairs of VEE blocks of different sizes.
    A decent brand Collet chuck and collets to suit.

    At this stage ,I can't answer that one, as I have only been there a week.
    The kids have been with out an instructor for 6 weeks as he left suddenly due to family problems.

    From what I gather its stage 1 & 2 MEM certificate. I am up on the metalfab side but need to catch up on the fitting and turning side.I will check with the Tafe F & T guys on that one to get up to speed with what their standards should be . From what I see,of their job sheets, it not too high as they only machine to .5mm tolerance

    I saw a 150mm vice on the machine ,but did not notice if it swivels.I'll check on Monday.There is a good clamp kit-the big one that H&F sells. Also I spotted a big face cutter 75mm- if you measure them by diameter.I have seen a pair of vee blocks -they would be 50mm square.I could not see a rotary table,tailstock or angles. The other school had them so I would see them as a basic must have.

    We have also got a big hydraulic clamp type band saw (I guess it would cut 150mm diam round bar)
    https://www.machineryhouse.com.au/Pr...stockCode=B034
    a 400mm Thomas cold saw, Water cooled spot welder,Segmented folder, 2 x 20ton hydraulic presses, 4 x oxy weld/cutting bays, stick/mig bays, and 5 x 2mx 14" swing lathes.

    I can stand at the front of the shed and see every student on every machine or in the weld /oxy bays.
    I am told at the moment I will be 5 days a week with the engineering kids next year.

    Basically the enquiry was about the cutting tools needed in the mill.They may well have been purchased as there is a pile of gear I have to go through still .
    It would be good to have an idea of what I am dealing with as I have not used collets for milling in the past.

    We used the end mills with a thread on the end of them,whee as I would think they would be suited to collets.

    Hi Grahame

    I purchased a Hare & Forbes Lathe for my garage and found it to be great value for money, as your new school will find with the mill.

    Pipeclay has just about mentioned all you need,but be carefull if the school intends to buy tooling from them as I found some tooling products I went to buy for my lathe are not ISO standard and I would have not been able to purchase carbide elswhere to fit.

    P.S Just been down to the garage to see if I have any room left for a mill, have had my eyes on those H & F around $5000 for a while now (just can't seem to hide things from my wife these days).

    Regards, Bruce

    I just looked at your last post and you mentioned end mills, if you buy slot drills they have the ability to machine a hole/blind hole vertically as well as your normal milling operation the same as end mills and still fit into the same collet chuck.They are more versitile than end mills and a bit stronger (pupil friendly).

    Regards, Bruce

    Hi Chips,
    There is a technique to be used here.
    It involves dirt,dust and cobwebs.
    A new looking machine is a dead give away.

    No dear ,I have had it for years ,here just look at the dust ,etc,etc.

    I am not a big H&F fan. I reckon most of their stuff comes out of the same factory as the rest of the generic machines.

    We have arranged for one of the local tooling retailers to come and see us and he will give us a demo on the tooling and application, so hopefully I will get to mention this fact to him.
    I am doing an inventory of inserts against his catalogue,so it should be obvious after a while.
    Thanks for the heads up.

    When it comes to you Collets if you move away from a Clarkson type Collet holder go for the ER40 or ER50 .
    The threaded end of the slot drills or end mills go into a posi lock type holder.
    They screw in and the centre in the rear of them will locate on a small centre in the base of the collet holder,they are good but if not fitted correctly when the collet nut is tightened to much force can be applied to the centre in the slot/end mill and they can or will crack around this point.
    You can still use screwed shank milling cutters in ER collet chucks.
    If you are dealing with a Tooling supplier and they are not contracted to the education facility that you are with get a few in to discuss tooling (Sandvik,Kennametal,Iscar etc) should be able to get them to make there quotes a bit more competitive if they no they have competition.
