The model of versatility, this line boring machine offers easy, flexible setup, a high power-to-weight ratio, and high-speed operation to boost productivity. Adaptable to a huge range of bore diameters, from 14.5 to 85.6 inches (368.3 – 2174.2 mm).
Specifications:Bar Diameter: 8 inches (203.2 mm)
Boring Diameter: 14.5 – 85.6 inches (368.3 – 2174.2 mm)
Max. Stroke: length of bar
Torque at Bar: 3350 – 6068 ft-lb (4542 – 8227 N•m)
Power Option: Hydraulic
Using 11.3 in3 (185.3 cm3) Hydraulic motor, produces 4783 ft•lb (6484.9 N•m) of torque at the bar, at 15.1 rpm.
Compact, modular components allow fast, easy setup, maximizing efficiencies, and minimizing downtime.
ID and End mount bearings feature spherical taper-lock roller bearings.
End mount can be fine adjusted by +/- 0.25 inches (6.35 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.
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.
– With leading & trailing boring head configuration, 2 boring heads can be used simultaneously.
For even greater facing range with longer radial travel, 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).
Hard chromed bars, straight to within 0.001 inch per foot (0.0254 per 304.8 mm).
Optional 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.
