Title: Boley 5LZ
Post by: smiffy on April 03, 2016, 06:28:00 PM

Had to make a new pin for a local farmers plough . 50mm dia and one end threaded 1-25 pitch on a reduced shank of 45mm. Material is EN24
So set my boley for semi auto screw cutting and this is a video of it working prior to cutting the thread.
The lathe  has 2 micro switches on the bed operated by stops on the apron . As the tool approaches the end of its cut the spindle is electro mechanically braked and reversed at 4x the cutting speed , when it has fully returned the spindle is reversed and cut put on and a the processes repeats itself  The lead screw is anti backlash and always engaged while screw cutting
There is no screw cutting gearbox but a large  selection of gears and it can cut Metric Imperial Modular and DP pitches

Now I get it.  :doh:

Size 3. (same as Camlock D1-3). I wonder how many different flavours of the KK short taper nose the germans came up with?

Certainly a better spindle nose than the threaded one.
