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.
