I'm in the need for a Dual contact slitting saw arbor.
The largest babbitt bearings we make get split into two equal halves on a Milwaukee model k horizontal with an indexer. We slide the bearings on a close fitting mandrel and tighten down with lid. I'm trying to combine this operation and many other secondary operations into one machine to improve throughput and streamline production.
I currently do some of the smaller bearings on an older cat40 hurco with a 4th axis. Some are also done on an old clausing knee mill. I am limited by the rigidity of these machines to make some of the heavier cuts in the larger bearings. I run these with a 1" arbor keyed holder with a gauge length of 4". The cutters are usually 3-4" in diameter and 3/32 to 7/32 wide.
A semi local machine tool reseller wants to try our largest bearing on their new dual contact Hyundai. But i cant seem to find any dual contact arbor holders with enough length.
The largest bearing is 8-1/4 diameter so i need approximately 4" gauge length with a 1-1/4 arbor. The larger the stem diameter the better, up to 2". The bearing is approximately 7/8" wall, 1026 annealed steel with a .03 babbitt lining.
We have always used HSS staggered tooth cutters to split the bearings. One reason is we can re-sharpen them in house.
I would prefer to use Maritool, but i understand that Frank may not have time to make a one-off.
I'm pulling my hair out trying to find something that suits, I will pay gladly to have one made.
If anyone has any suggestions to improve what we are doing here I'm all ears.
I have though about trying some inserted cutters, but there are so many styles to sort though, and they are prohibitively expensive.
