    Default Rego Fix Collet Nut - Can Anyone Help?

    I've been chasing a new Rego Fix Hi-Q ER32 collet nut for some time. These nuts appear now and again on US Ebay but are often the coolant or bearing type nut and, or, the seller will not ship to Australia.

    I contacted the local agents, K2 Engineering in Malaga and was advised that they would confirm the availability and cost of the nut. Never heard from them again after ringing back a second time. Remember, this is only one nut. I have bought a small amout of Kennametal tooling from them before, but I guess, so what.

    A search online revealed that SEI Australia, located in South Penrith, were Rego Fix agents. Sent an email to a fellow there by the name of Shaun Rees, who told me, yes the nut was in stock, but I would have to order it from their West Australian distributor, K2 Engineering.

    I sent him another email asking if it was possible to purchase the nut directly from SEI to which I received no reply.

    Does anyone out there deal with SEI and would they be prepared to buy one nut on my behalf, all expenses paid by me?

    The Rego Fix part no. is 3432.00000. This is the STANDARD Hi-Q nut.

    Regards
    Bob.

    Thank you for your kind offer, Pipeclay but I have it covered.

    Fellow Schaublin 13 owner, Phillip " Metalman" had sent me an email, offering to call in at SEI.

    I called the firm, in vain, this morning to confirm the price. They must still be on holidays.

    As fate would have it, there is a standard ER32 nut on Ebay at the moment. Unfortunately it is accompanied by two lesser Chinese nuts that push the cost of postage up. The minimum winning bid would be $52 US including the postage. I had asked the seller whether he would ship the Swiss nut alone and his response was that it was too much trouble...

    Even still, knowing how severely we get gouged locally, the Ebay price may not be far off SEI's price.

    Regards
    Bob.

    Hello June,

    Thank you for your reply.

    I purchased the Rego Fix nut, along with it's two Chinese cousins from the United States.

    It was easier than expecting a fellow forum member to do the shopping on my behalf.

    Regards

    Bob.

    Gregory, You had better send me your address,

    The difference I have found with the Rego Fix collet nuts that I have, in both ER25 and ER32 sizes, is that the collet is positively and securely retained in position. The Chinese nuts do not offer the same retention because the opening in the retaining flange within the nut is more elongated. The collet dangles in a lop sided fashion and is very easily dislodged.

    When I acquired the 13 it came with a Schaublin E32 (not ER) ISO30 chuck and no collets. I had read an article on PM about a Volsto angle head in the Bridgeport forum. They were fitted with E collet chucks and one of the blokes had said you could simply swap the nuts to enable the use of ER collets. Which is what I have done on the high speed head (ER20) and the 30 taper chuck. I've been using a Mari Tools ER32 nut till today. The Mari nut suffers from the same Chinese ailment most probably because Frank Mari sources his gear from China. Frank's nut is shown in the last photo.

    I have six ER collet chucks that I have purchased from CTC and with CTC collets there is varying runout. With the Schaublin / Rego Fix combination, I'd have to get out my 1um Millimess indicator to measure it.

    Default I may have been a bit harsh.

    In a post regarding Rego Fix collet nuts I had said that collet chucks along with the collets that I had bought from CTC had displayed varying amounts of runout. I didn't say how much. But I was suggesting it wasn't flash.

    Yesterday I had been using an ER40 NMBT30 chuck in the vertical spindle of my mill.
    The chuck was a CTC purchase. The one inch collet was purchased from Mari Tools in Illinois. I was using a Clarkson 1" shank slot drill.

    I just went and set up a tenth indicator to run on the ground shank of the drill. That's 95mm from the spindle nose. Loosened the nut and moved the cutter a few times.
    Got a bit of a shock. Repeatedly 0.0002" TIR ! Very close to FA.

    Hi Bob...I'll PM my address. Let me know how much and how to pay. Is that 0.0002 runout with the Regofix nut or the CTC?. I have two sets of ER32 and two chucks, all from CTC. I have only checked one chuck/collet combination and it was about the same.

    Do you think the Maritool collets better than CTC's, or about the same?

    Default Runout.

    Gregory,

    The two tenths was with a 1" Mari Tools collet in the CTC chuck. I bought two used Rego Fix ER40 25-24mm collets on US Ebay. I checked the runout. The first collet holding a 25mm slot drill had a TIR of 0.0004". The TIR of the second Swiss collet was a vast improvement, 0.0001". These collets show considerable signs of hard use, one obviously hammered more than the other.

    I then reinstalled the 1" Mari collet and tightened it down onto the 25mm drill shank.
    TIR of 0.0003".

    I don't have any CTC ER40 collets to make a comparison but CTC claim their collets have a maximum runout of 0.0006"

    Most of this doesn't really mean that much to most but it would be a shame to squander the accuracy of a machine by using lesser tooling.

    Still, it's not like I'm making guided missiles.

    Wanting something better than the run-of-the-mill is laudable in my book.

    Greg,

    What I have not mentioned is the accuracy of the CTC chuck.

    0.0001" runout suggests the chuck is doing a pretty good job.

    The ground outer body of the chuck, when mounted in the 13's spindle, has about 0.5mm/0.020" runout. I initially thought that I had a lemon on my hands, but when you think about it from a manufacturer's point of view, why waste money precision grinding the exterior, especially for the price these things are sold for. The external runout might create a balance problem at high speeds but I can't see myself having an issue with that. The 13's highest speed is 2000rpm.

    Send me your address.

    Bob.
