L-720M STUD-MOUNTED MACHINE TOOL LASER

L-720M STUD-MOUNTED MACHINE TOOL LASER

Descriptions

The L-720M was designed specifically to be used for both lathe-type alignments and machining center-type alignments. It is virtually the same as the L-720 except the laser can be removed from the base and inserted into a spindle chuck using a .500" mounting stud. Like the L-720, it has a single, continuously rotating laser plane with a straight-line laser that is plumb to the plane. The laser-tilt base includes split-prism levels that are accurate to1 arc-second. The laser mounts on a machine or stable base so that the laser plane can project the reference out to 100'. The laser may also be mounted at a 90º angle, producing a vertical scan plane to measure column geometry.

APPLICATIONS

  • Turning Applications (Cylindrical, OD/ID Grinders, Lathes)
  • Machining Centers (HBM, VBM, VTL, VMC, HMC, Gantries, Surface Grinders)
  • Rotary Dial Machines
  • Transfer Lines (spindle)
  • Boring Bars

FEATURES

  • Measures and corrects errors in both machine bed flatness and column squareness.
  • Mounts in spindles for headstock-to-tailstock or
    spindle-axis-to-master-part alignment.
  • Laser plane flat to 0.5 arcsec in 180º sweep and 0.25 arcsec in 90º sweep.
  • Plumb beam plus standard continuously rotating laser are square to within 1 arcsec.
  • Specialized base equipped with illuminated, split-prism levels accurate to 1 arcsec.
  • Mounts on machine or stable base, such as the L-106, to project reference out to 100' in radius.
  • Mounts at 90º angle to produce vertical scan plane for measuring column straightness and flatness.
  • Instant with virtually no warm up.
  • Fast, simple set-up.
  • Targets provide live data display.
  • Laser and targets fit into portable carrying case.
