I am looking for an adjustable boring bar holder
Machine: Nakamura WT150
Max RPM = 6000
2 holes – one is brass -- one is bronze
Hole size: .1565+/-.0001
Roundness within .00015
ER-32 collet holder
I am currently using a Criterion TMT-0750 boring bar holder in an ER collet.
Solid carbide boring bar.
I am having a difficult time adjusting size.
I need a super precision adjustable holder so that I can adjust within at least .0001 – preferably adjustable to within .00005
