GemPower Right Angle Attachment with Arbor and Arbor Support for Vertical Milling Machine with NMTB40 Spindle
This unit was purchased for our inventory a few years back along with some R8 spindle mount units. I sold all the R8 units and THIS UNIT IS FOR NMTB40 Taper Spindle. This is a rare bird....I could't find this product listed anywhere.
IT is NOT for BT40 taper spindle...
IT is NOT for CT40 taper spindle...
Current NEW price of a NMTB40 RIGHT ANGLE KIT LIKE THIS IS OVER $2,000.00 and it is hard to find, long delivery.
Which milling machine do it fit?
The unit was ordered to fit the large 40 taper Acra made by Je Fong in Taiwan. That probably don't mean anything to you folks, so let me tell you how to figure this out. First, your machine MUST have a NMTB40 Taper spindle. If you have the QC spindle nut, it will have to come off. You must have a regular drawbar in your machine or powered (usually air) drawbar. Second, the OD of your spindle should be about 4.125". If the RIGHT ANGLE attachment will fit on you machine, then you can use it with a stub holder or endmill holder or drill chuck holder that is also NMTB40.
There is a possibility that the RIGHT ANGLE attachment will fit your milling machine spindle, but the arbor support MAY NOT fit. LOOK at the pic of my hand sketch. The angle of the dovetail ways is 50 degrees. Look at the cross section measurements of the dovetail ways. This unit fits on dove tail ways on the bottom of a LARGER ram than is usual for a R8 head.
Information: (Please look at the pics!!!)
* Right angle head mounts to NMTB40 taper using your normal drawbar
* Your quill should be should be about 4.125" in diameter if you have NMTB40 Spindle
* Look at the drawing PIC of the arbor support...will this fit the dovetails under your ram?
* There is a draw bolt to lock in the arbor (included) or you could use a NMTB40 end mill holder or shell mill arbor or even a Jacobs chuck holder, all readily available.
* The included arbor is about 12" long (actual arbor space.)
