L-702SP Spindle Alignment Laser With Scan Plane

Sept. 20, 2018
Hamar's spindle alignment lasers measure in 4 axes simultaneously.

Offering highly accurate and fast alignment of lathes, turning centers, and other machinery, the L-702SP Spindle Alignment Laser with Scan Plane adds a perpendicular scan plane to the spindle laser beam for checking cross-slide, turret axis squareness, and other milling axes in multi-axis, mill-turn machines.


Inserted into spindle chucks and aligned to the spindle's rotation axis, the lathe-bed straightness and parallelism to the headstock are checked. The cross-slide, turret or milling axes can be checked for squareness or parallelism.


The data is sent to Hamar Laser's MultiTurn10 Software for recording and analysis with a very high measurement resolution of .000001 in. (0.00025 mm). The L-702SP can also be used to check machine-bed guideway flatness/leveling.

  • Quick alignment check in 15 minutes and get full alignment data in 25 to 30 minutes
  • Laser and target mount directly into the spindle and tailstock allowing the entire length of even the largest lathes to be quickly and easily aligned without changing setups
  • Ultra-high resolution of up to .00001 in. (0.00025 mm) combined with software to correct mounting errors produces a very accurate alignment, less than .0001 in. (0.0025 mm) and .0001 in/ft (0.0083 mm/m) under good environmental conditions
  • Large, easy-to-see alignment displays, real-time alignment data and spindle graphics, and a 6-step procedure guide users through the alignment with on-screen help instructions. 
  • MultiTurn10 records data for all axes of multiturns, lathes, turning centers, and some machining centers, calculating straightness, flatness, and squareness results and providing a comprehensive report
  • A perpendicular laser plane easily measures the squareness of linear axes without additional setups
  • Mounts directly in the spindle to project its axis of rotation out to 100 ft (30 m)
  • The laser and target both offer a .4995 in. (12.69 mm) mounting stud for simple fixturing to hold them in place
  • Real-time measurement data in 4 axes (V center, V angle, H center & H angle)
  • Measures pitch and yaw angular data for linear axes with a standard resolution of .00008 in/ft. (0.007 mm/m) 
  • Hi-resolution optic provides .00004 in/ft. (0.0035 mm/m)
  • Vertical and horizontal angular adjustments to precisely adjust the laser to the spindle’s axis of rotation or to align the laser plane to reference points
  • Rechargeable battery runs for up to 8 hours
  • Dimensions: 4 x 3 x 2 in. (101 x 74 x 45 mm)
  • Only needs 10 in. (254 mm) of space between the spindle and tailstock or sub-spindle


  • CNC Horizontal Boring Mills
  • CNC Horizontal and Vertical Machining Centers and Gantries
  • CNC MultiTurn Machining Centers
  • Cylindrical, OD/ID Grinders
  • Horizontal Boring Mill Indexing Checks for Deep-Bore Applications
  • Injection Molding Machines
