The L-702/L-702SP are Class II diode lasers designed primarily for alignment of spindles to sub spindles or tailstocks. They have 2 axes of angular adjustment to align the laser beam to be co-linear the axis of rotation of a spindle in which the unit is mounted.
The L-702 Spindle Laser comes in 2 configurations:
- L-702 Spindle Alignment Laser – is a straight-line laser for spindle alignments in lathes, turning centers, OD grinders, slant-bed lathes and transfer-line and rotary-dial machines.
- L-702SP Spindle Alignment Laser with Scan Plane – this adds a perpendicular scan plane to the L-702 spindle laser beam for checking cross-slide, turret-axis squareness and other milling axes in multi-axis, mill-turn machines.
- Rotary-Dial Machines
- Transfer-Lines
- Cylindrical, OD/ID Grinders
- Horizontal Boring Mill Indexing Checks for Deep-Bore Applications
- Multi-Turn Machining Centers
- Rotary-Dial Machines
- Transfer-Line Spindle Alignments
- Turning Centers and Lathes
- Twin-Barrel Extruders
- The laser and target both offer a .500 in. (12.7 mm) mounting stud for simple fixturing to hold them in place.
- Center resolution of .00001 in. (0.00025 mm) and angular resolution of .00001 in/ft (0.0008 mm/m).
- Live measurement data in 4 axes (V center, V angle, H center & H angle) simultaneously.
- Windows 7/8/10-based Lathe9 Software with large, color graphics corrects mounting errors, calculates shim values and provides an alignment report showing all the alignment parameters of lathe alignment.
- Windows 7/8/10-based Spindle8 Software with large, easy-to-see alignment displays, live alignment data and spindle graphics, and a 4-step procedure guide users through aligning spindles to master parts on transfer-line spindle applications.
- L-702/L-702SP mounts in the spindle to project its axis of rotation out to 100 ft (30 m).
- Vertical and horizontal angular adjustments to precisely adjust the laser to the spindle’s axis of rotation.
- Rechargeable LiPo battery runs the lasers for up to 8 hours.
- Compact and rugged 4 x 2.9 x 1.7 in. (101 x 74 x 45 mm).
- Only needs 10 in. (254 mm) of space between spindle and tailstock or sub-spindle.
