Our patented 4-axis L-700 Spindle 
Alignment System is a powerful alignment 
tool that will help you to align boring mill, 
cylindrical grinding, lathe and turning-
center applications up to 70% faster than 
conventional or interferometer methods. 
With a resolution of .00002" (.0005 mm), 
live data output and large, color computer 
graphics, the L-700 is the perfect tool to 
align headstocks, spindles, sub-spindles 
and tailstocks quickly 
and accurately.  

 

Turning Center 
Alignment Simplified Even on Large 
Lathes  

The critical alignment of a lathe or other 
turning-type machine is the parallelism of 

the axis of rotation (AOR) of the spindle to the machine bed and alignment to the tailstock, sub-spindle, turret or tool 
holder's AORs.  

 

Conventional methods are very cumbersome and time consuming and are practically useless on large lathes. The L-700 
vastly simplifies the task by inserting the laser right into the spindle chuck  and the T-261 4-Axis Target into the sub-
spindle or tailstock. The laser is aligned to the spindle axis of rotation out to 100' (30.5 M). This becomes the reference 
from which the ways, tool holder and tailstocks can be measured and aligned

 

using the T-261. The software displays a 

live reading of the horizontal and vertical center (offset) readings and the horizontal and vertical angular (slope) readings 
of the tailstock to the headstock. 

 

Live Display of Misalignment Data in 10 minutes  

The L-700 Spindle Alignment System is so easy to set up that 
you can have a quick measurement of misalignment data in 10 
minutes. The Windows-based software speeds setup and data 
taking and even corrects for mechanical mounting errors!  

 
As with all Hamar Laser products, the L-700 provides a live 
display in four  axes of misalignment data, which means you 
can align the tailstock, sub-spindle, etc. while the laser is still 
in the machine. This is especially useful for tailstock 
alignment, as it requires 4-axis calibration (horizontal center 
and angle and vertical center and angle).
