John Stevenson has been showing his new design of ER32 machining blocks on a few sites, and seeing as I managed to obtain a pair today, I thought I would show them on here first.
As most of you most probably know, this is the normal method of quickly machining flats on the ends of bars, but you will only be able to use them if you also use 5C collets.
John S has designed a pair of blocks for use with ER32 collets, as a lot of people now use these as standard on their machinery, so it is good economics to use those rather than having to buy 5C as well.
As you can see, the block is drilled all the way through, so long pieces can be held to have flats machined on or cross holes drilled across their end.
The main block is a lot shorter than the other set, but these new ones also have the threads protruding from the end, so for OAL it is swings and roundabouts on that score.
By having the main blocks much shorter, they sit very nice and square in an upright position on it's back face. This is a 6" vice, and the main block sits fully down into the vice and the collet nut sits above the vice jaws. By using a backstop, holes in the end of bars can easily be drilled in any combination you can configure with these blocks.
Talking about backstops, because the nut is larger than the main block, you can use that as a front stop by pressing it against the side of the chuck jaws. One thing less to worry about.
So these are the blocks, and in the short time I have had them, I gave them a good check over and they really are exceptionally well made.
Rather than having to buy them as a set, you can buy each one individually. Also, because the person buying them will also normally have their own collet nut, they are not supplied, so keeping the cost down, but they are available if needed.
So where can you get them from?
The usual place, about the only retail company doing any R&D to see what we really want, and making them available to the masses.
