Hi Guys,
After a few months using my al-960b and HM-46 I am staring to get a feel for them. I figured now that they have been bed in so to speak it was time to get to know them more intimatley and a good opportunity to set them up and take readings of allignments. It has given me time to gain some knowlegde and tackle things I wasn't so comfortable with at the start.
In regards to the lathe I have started taking readings of headstock to tailstock allignment using a mt3 test bar. I have the chuck off and fitted the mt5 to mt3 adaptor and deadcenter. I have got the horizontal allignment within 0.02 mm however the vetical allignment is approx 0.06-0.08mm rising toward the tailstock with the tailstock fully extended. I have ajusted the tail stock mandrel to within 0.01mm on the vertical.
I have the magbase on the cross slide and am turning the carriage wheel back and forth to attain these readings. The readings are consistent everytime.
I took off the tail stock and gave it a good clean underneath and this had almost no effect on readings.
As far as the mill goes I have issues with the nod this is about 0.1mm front to back when the the head is about 80mm from the table and everything is locked up. When I raise the head to my "normal" work range approx 180-220mm above the table(extend the quill right out) the nod is almost spot on.
The tramming left to right i have got within0.01mm so all good there.
All measurment on the mill are taken with the head, quill and table locked. The lathe measurements are taken with the tailstock and mandrel locked.
Would love some advice especially regarding the lathe vertical tailstock allignment. Anyone on the northshore of Sydney able to maybe come say hello?
Thanks:U
