To make this new range possible with just one boring head, the engineers at BIG KAISER came up with a new, rigid, dynamic center-mounted boring bar/insert holder capable of maintaining consistent precision throughout its full ran
Previously, center-mount boring bars were used to cover a max Ø2.125”, and an outboard insert holder clamped to the side of the head covered Ø3.150”-6.000”. This left a significant gap of over Ø1” that could not be covered, and an additional head from the 310 series was needed to fulfill the full bore range to Ø6”. As a result, this new kit saves users nearly $2,000 when compared to the previous generation kit.
The tooling and carefully selected accessories come stored in a molded plastic carrying case with foam inlay to keep the components organized and protect the instruments when not in use.
The EWN 2-50XL boring head features adjustments of Ø.0002”/div. Coolant through is standard with a max pressure of 300 PSI. When using the outboard insert holders – an included coolant nozzle inserts to the center of the head for direct coolant delivery to the cutting edge. The same outboard insert holders can simply be assembled in reverse to permit back boring.
