Using Involute Gear Cutters on a 1100 Series 3

Mill
1

I looking at using an involute gear cutter on my 1100 series 3 with the microarc. However, I am not sure what TTS arbor to hold the gear cutter. Most gear cutters have a 22mm keyed center hole. This does not seem to match up with the TTS line.

Any thoughts on this?

Thanks
Mike

There are FMB22 arbours on eBay (see for one example NEW 3/4 FMB22 1.38 FACE MILL TOOL HOLDER ARBOR USA SELL | eBay) that might work. The key may not be necessary since a gear cutter doesn’t usually require a lot of torque.

Can’t make them for that price. But if push comes to shove, I make mine. I’ve made ER20 and solid holders for my drills. make the blanks on the lathe then drill, bore, then ream in the mill with the tools in a tooling block held in the vise. Very true to the spindle. ER’s are made on Hardinge GS200. Nuts are purchased and runout has never been more that .0003. I imagine that is plenty close enough for gear cutter.

Thanks for the reply. After looking at options, I am getting a 7/8" center hole gear cutter and a SS shank milling arbor (7/8") to 3/4" shaft from Travers.com. I will use a 3/4" ER32 collet to hold the milling arbor. A little cost, but it should be a solid setup.

Bill, thanks for the reply. As you will see in my reply to Ken, I came up with an approach which should work. Hopefully next week I will put it to the test.
