Product Advantages

Powerful Yet Compact

Take the power of a stationary machine to the job site to solve tough machining challenges in record time.

Using 11.3 in³ (185 cm³) Hydraulic motor, produces 2280 ft-lbs (3090 N•m) of torque at the bar, at 29 rpm.

Compact, modular components, many which can be lifted by hand, allow fast, easy setup, maximizing efficiencies, and minimizing downtime.

Versatile and Flexible

Huge machining range bores from 10.25 – 58.25 inches (260.4 – 1479.6 mm) in diameter, and faces from 9.6 – 62.5 inches (243.8 – 1587.5 mm).

ID and End mount bearings feature spherical taper-lock roller bearings.

End mount can be fine adjusted by +/- 0.625 inches (15.9 mm) to center the bar.

Optional dual action boring/facing arms increase facing range, and allow for both boring and facing without switching equipment. Full-length square ways on boring/facing arms allow for quick positioning anywhere along the arm. Attaches to the net fit tool carrier by compression-clamping, to provide maximum tool stability.

Machine is highly adjustable. The tool carrier, half nut, alignment of boring/facing arm, and tool carriage can each be adjusted to maximize machining performance.

With leading & trailing boring head configuration, 2 boring heads can be used simultaneously.

For even greater facing range and longer continuous stroke, the new boring/facing arms are available. Setup is quick & easy, featuring industry standard quick-change tooling for both boring and facing operations.

Highly versatile tool holder block accepts industry standard tooling with a nominal 1 inch (25.4 mm) square shank.

Tool post on the boring/facing arm can be rotated to provide maximum flexibility in machining setup (including some cantilevered configurations).

Net fit tool carrier can be clamped to bar for facing operations. For boring operations, carrier can be adjusted to remove clearance between carrier and the bar. This flexibility also ensures maximum rigidity for either operation.

Net fit tool carrier designed with a split frame to simplify installation on the boring bar. It can be configured to use either the boring head set for boring or facing, or the new boring/facing arm assembly.

High Quality Design

Features a uniquely-designed modular tool carrier which provides a new level of strength and rigidity by channeling machining forces directly to the boring bar through strategically-located adjustable guide shoes.

Chromed bars, straight to within 0.001 inch per foot (0.0254 per 304.8 mm).

Gun-drilled bars with optical targets available.

Adjustable, removable half nut increases net fit tool carrier flexibility. Easy removal of tool carrier allows for machining of multiple bores.

Backlash adjustment nut allows in-the-field adjustment to eliminate backlash in the tool carrier, and extend the life of the machine.
