L-733 Precision Triple Scan® Laser

Hamar Laser’s L-733 Precision Triple Scan® Laser Alignment System is a highly accurate and versatile alignment tool. This powerful yet easy-to-use system is ideal for quickly and accurately checking and fixing the geometry of most lower-accuracy machining centers and excels at many other demanding applications. Our Ultra-Precision Series L-743 and Precision Series L-733 are the only alignment systems in the world to offer three automatically rotating laser planes with the extreme high accuracy needed for today’s ever-tightening tolerances. This creates a powerful tool that not only measures surface flatness, squareness and straightness, but fixes complex alignment problems in a fraction of the time needed with conventional methods.

System Highlights

  • Fast: Data updates in real time to align boring mills, gantries and machining centers up to 70% faster than traditional methods or laser interferometers.
  • Easy: Measures the three main axes of a machine at the same time for flatness, straightness and squareness, and checks any additional axes for parallelism usually with the one setup.
  • Accurate: Precision laser planes have a flatness of 2 arc seconds (.00012 in/ft or 0.01 mm/m) in a 180º/360° sweep and 1 arc second (.00006 in/ft or 0.005 mm/m) in a 90º sweep.
  • Versatile: Ideal for nearly all types of lower-accuracy machine tools, as well as many other applications including aircraft assemblyautomotive transfer lines, injection molding machines, roll alignment and laser and water-jet cutting machines.
  • Smart: Powerful Windows-based alignment software, combined with advanced wireless interfaces, makes collecting and analyzing alignment data fast and easy.

L-733 Precision Triple Scan® Laser Alignment System

We designed the L-733 Precision Triple Scan® Laser to bring the innovative power of our high-end machine tool geometry lasers to lower accuracy applications like water jet and laser cutting machines, steel and textile mill roll alignments and large fabrication alignment. It has all of the timesaving and useful features of the L-743, with a few minor exceptions: lower accuracy, lower price and a medium adjustment base.

Usually Only Requires One Setup

Like the L-743, the L-733 offers 3 automatically rotating laser planes that not only MEASURE but it also FIX alignment errors in a fraction of the time needed with conventional methods. In most cases, it can align a machining center with only one setup.

High Accuracy at 30% Lower Price

With a price that is 30% lower, the L-733 is an affordable alternative to our high-accuracy machine tool alignment lasers. It features 2 vertical and 1 horizontal continuously rotating laser planes, a pitch, roll and yaw (medium) adjustment base, for setting the laser planes parallel to reference points, 2-arc-second level vials and a powerful magnet for maximum stability.

One of the critical components of any laser system is the straightness or flatness of the laser beam or plane, as this is the reference from which the measurements are made. The 733’s laser planes are flat (in a 360° sweep) and square to 2 arc seconds (0.00012″/ft or 0.01 mm/M). In a 90° sweep, the laser planes are flat to 1 arc second.

Measure Dimensions with New Wireless Targets

Another critical component of laser alignment systems is the resolution of the targets. This determines how close the measurements can be made.

For higher accuracy applications, our wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) is an ideal alternative. The targets have up to a 1″ (25 mm) measuring range, resolutions as low as 0.00002″ (0.0005 mm) and can be used up to 100 feet (30.5 meters) from the readout (R-1357-2.4ZB), which uses a Ruggedized Trimble Android PDA and color software to display up to five targets simultaneously.

Alignment Applications

For alignments with tolerances of 0.00015″/ft or (0.01 mm/M) or greater, the L-733 can quickly measure and correct machine geometry with minimal setup for the following applications:

  • Machining centers (HBM, VBM, VTL, VMC, HMC, gantries, surface grinders)
  • Water-jet and laser-cutting machines
  • Vertical and horizontal press alignment
  • Roll alignment (rubber, steel, textile and lower accuracy film lines)
  • Aircraft assembly (seat track alignment, setting water, butt and station planes, wing-to-body and body-to-body join alignment, etc.)
  • Saw mills
  • Leveling machine beds and ways
  • Checking the alignment of large bearing surfaces and fabrications
  • Measuring and aligning:
    • The flatness of almost any horizontal or vertical surface (squares, frames, ways, flanges, circles, etc.) or axes.
    • The straightness of vertical and horizontal axes
    • The squareness of any vertical machine axis or surface to a horizontal axis or surface
    • The squareness of any 2 vertical surfaces or axes
    • The parallelism of vertical or horizontal surfaces, even if those surfaces are 100 feet (30.5 meters apart)
    • Way twist and parallelism between vertical surfaces
    • Way twist and parallelism between horizontal surfaces
  • Checking plumb of a vertical surface up to 100 feet (30.5 meters)
  • Measuring surfaces up to 200 feet (61 meters) long with 1 setup

Color Alignment Software

For wireless recording and analyzing alignment data, our color, 3-D flatness and squareness analysis software, Plane5 or Machine Tool Geometry, simplifies and streamlines the data analysis process. Plane5 can measure up to 7 different surfaces in one project setup file and present a color, 3-D graph of the flatness and squareness analysis for each surface. Machine Tool Geometry software can measure and analyze 4 different machining center-type machines. And you can add your own machine configuration as well!.
