Hello unclesyd,
Well, what a timely question. I just yesterday received our new single blade reamer from Walter Germany. We are now able to produce the items we make to the standard we require.
The reamers you suggest are much too short, by around 80mm, or over 3 inches. We require 200mm...
Matt, if you read the posts, you will find I am in Australia. We don't do phone calls to the USA.
How much and when can you do a reamer? I already sent an RFQ on your website. Any chance of replying?
How would we go with 8 inch depth of cut on the bore with a broach? Would be highly unlikely I would thing that this would be possible with typical workshop equipment. I won't bother looking for a local supplier, have had very poor experiences with almost all suppliers I have dealt with in AU to...
unclesyd said:If your tolerance will allow it you might want to use a Dreamer to finish your holes.
In the Dreamer information they say they can go to 1.5" as their standard size is 5/8" max.
You could buy one at you local tool supplier and check the results.
A dreamer being a drilling reamer...
Hello unclesyd,
What do you mean by "both holes could be broached?" You mean a broach reamer?
We won't be changing our process to include any milling or grinding of the holes - we don't have the gear, and I don't use contractors for such things, we are Australia where manufacturing is almost a...
Oh, and the other issue is the next project we are working on is not a through hole, but not a blind one either - just a reduction. So any tooling with long leads will not work either, as it needs to machine mostly up to an internal shoulder.
Ok, so how do we go from the 21,50mm hole to 22,00mm? A hone won't do this will it? Standard type machine reamers do not work in this material as it tears.
What is the issue with single blade reamers?
Also, we are working with annealed tool steel, not hardened. Process is mostly completed...
Hmmm, this sounds rather close to home for me.
I can't say much but that only those that don't fail, have never achieved anything.....I call failure a learning opportunity :)
Start small. Meaning, really small. Such as bench top gear. It is not the gear, it is the operator. Don't let anyone...
Hello all,
We have a new drilling system, after waiting forever it seems on suppliers to get their lazy arses into gear, we finally have one. It is a Mapal unit, in 21,50mm diameter.
Now we require a single blade type reamer to go with the high speed / high penetration rates we need for...
Yes, even after this long, we are only just getting into drilling a decent hole. We have now acquired a Mapal drilling system, which is awesome.
The Mapal is not like the Allied unit, as it is a complete head, rather than a spade type flat bit. ALso has 4 x guide pads on the sides of the head...
Hello everyone,
Have been keeping an eye on this thread, although not posting. An update of sorts for drilling:
We have now tried a few options, only one so far working: that being a std HSSCo drill. Guhring and other insert drills did not work at all, but I havent tried the allied unit.
We...
Hello all,
We are in the process of manufacturing rifle actions. The firing pin of said actions is driven by a belleville washer stack, rather than the typical helical spring.
We are looking for belleville washers in titanium, but are having some trouble finding them. Any ideas?
Size: 6,2 x...
dgallup,
The steel has been chosen by the designer for its particular suitability to this task, and that it has very little distortion after heat treatment. It also has a high content of nickel and chrome, so is not far from SS itself.
There is only about 0.004" play between the bolt and body...
Fastener? unclesyd, it is a rifle action, the main parts in question here being the action body - 187mm long x 38mm diameter, 22mm bore, and bolt that fits into the body.
The bolt is the part in question - usually hard chrome plated due to many cycles to lock the action in place - many...
