Range of Precision Boring with One Head
April 1, 2016
The EWN 2-50XL Boring Kit from BIG Kaiser Precision Tooling Inc. now offers a turnkey precision boring tooling solution for the diameter range of O.700" - 6.000" in its entirety. "To make this new range possible with just one boring head, the engineers at KAISER came up with a new rigid dynamic center-mounted boring bar/insert holder capable of maintaining consistent precision throughout its full range," said a company spokesperson.
Previously, center-mount boring bars were used to cover a max O2.125", and an outboard insert holder clamped to the side of the head covered O3.150" to 6.000". This left a significant gap of over O1" that could not be covered, and an additional head from the 310 series was needed to fulfill the full bore range to O6". "As a result, this new kit saves users nearly $2,000 when compared to the previous generation kit," said the spokesperson.
The tooling and accessories come stored in a molded plastic carrying case with foam inlay to keep the components organized and protected when not in use. Each kit includes:
- A Series 112 EWN 2-50XL finish boring head
- Two center-mount steel boring bars and corresponding screw-on insert holders for O.700"-3.150"
- Three outboard insert holders for O3.150"-6.000"
- Coolant nozzle
- A 10-pack of carbide coated TC11 inserts with a .016 nose radius (for general steel and cast iron)
- Two wrenches.
The EWN 2-50XL boring head features adjustments of O.0002"/div. Coolant through is standard with a maximum 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 be assembled in reverse to permit back boring.
If needed, the system is expandable for deep hole boring with carbide bars and diameters as small as .080", and additional accessories can be ordered for super-fine balancing, O.D. turning and chamfering.
