Triple Scan Laser Alignment System

Laser Systems for Geometric AlignmentL-730/740 Series Single-Axis/Multi-Axis Precision Alignment and Analysis Geometric Alignment Laser SystemsHow Lasers Work — Principles of OperationLASER is an acronym for LightAmplification by Stimulated Emissionof Radiation. Lasers radiate in a singlewavelength, in one direction and in astraight line, and are detected by posi-tion sensing detectors (PSDs). PSDsdetect and convert the center of ener-gy of the laser spot into a calibrateddigital reading for output to a hand-held readout or computer interface.Continuously sweeping laser planes areproduced by bending a laser beamprecisely 90° using an optical pen-taprism. Hamar Laser applies apatented correction process to thepentaprisms to produce ultra-flat,continuously sweeping laser planes.Laser planes are used as referencesto measure the flatness, straightnessor squareness of surfaces or axes ofmachines. Three points are neededto make the laser plane parallel to asurface. However only 2 points areneeded to measure the straightnessof an axis or a machine way.The laser plane is made parallel(“bucked in”) to a surface or line ofmotion by adjusting the pitch, rollor yaw of the laser base until laserproduces the same reading at eachreference point using 1 target.A Hamar Laser System For EveryAlignment NeedMachine Tool• Horizontal and Vertical MachiningCenters• Horizontal and Vertical Boring Mills• Vertical Turning Lathes• Large Lathe Beds• Floor and Spar Mills• Gantries• Vertical and Horizontal Presses• Transfer-Line Wing Bases• Roll-Forming Machines• Machine Tool Assembly andCalibrationPlastics• Injection Molding Machines• Film Lines• Blown-Film LinesLeveling• Split Joints On Steam Turbines• Machine Bed LevelingRoll Alignment• Paper Mills• Printing Presses• Continuous Casting Machines• Steel Mills• Aluminum Mills• Textile MillsQuality Control• Large-Part Flatness, Straightness and Squareness Checks• Surface Plate Calibration• Calibration of Large Fixtures and Jigs• Checking Flatness when Scraping Machine RailsFabricating Machinery• Tube-Bending Machines• Routers• Water Jet Machines• Laser-Cutting Machines• Woodworking Machines• Saw MillsFabrication Alignment • Wind Turbine Flange Parallelism• Truck Bed Assembly• Agricultural Machinery Assembly• Large Construction MachineryAssembly• Locomotive AssemblyAerospace• Body-to-Body Join Assembly Alignment• Seat-Track Alignment• Aircraft Interior Alignment (Storage Bins, Gallies, etc.)• Wing-to-Body Joining Alignment• Floor Beam Alignment• Jig/Tooling Calibration and LevelingShip Building• LNG Tanker Hull Construction• Section Alignment and Layout• Elevator Shaft Alignment• Gun-Bearing AlignmentApplicationsWhy Laser Alignment?Sooner or later everything goes out of alignment.Machinery and process lines, when properly aligned,run better, last longer, require less maintenance, lowerproduction costs and improve productivity.Hamar Laser systems offer significant advantages overtraditional alignment devices:• Up to 70% faster• Simultaneous multi-axis alignment• Ultra high accuracy and reduced setups• Target data automatically updates with each adjustmentAs the leader in laser alignment technology, weintroduced the world’s first flat laser plane in 1974,and the first automatically sweeping laser plane in1985. Today, no one can match our innovative systems for accuracy, versatility, fast setup, ease of use and the immediate, real-time generation of alignment data.Hamar’s Geometric Alignment CapabilitiesFlatness (Level)• Tables and Separated Surfaces• Machine Beds and Lines of Motion• Rail, Vertical-Column and Cross-Rail Twist• Surface Plates• Pitch and Roll Angular MeasurementsSquareness• Columns to Tables or Rails• X to Y Axis, Z to X Axis and Z to Y Axis• Gantry StaggerStraightness• Machine Beds and Lines of Motion• Column Travel• Yaw Angular Measurement• Beams or Other StructuresParallelism• Master Rail to Slave Rails on Gantries• A, B, C & W Axes to Main Machine Axes• Roll-to-Roll• Platen to Platen, Ram to RamProperly Aligned Machinery AndProcess Lines Run Better, Last LongerStraightnessFlatnessSquarenessRail FlatnessParallelism and Tie-Bar SquarenessRoll ParallelismCase HistoriesAircraft AssemblyAn aerospace company needed a reliable way to keep alarge tooling fixture constantly level during production.They evaluated a laser tracker and Hamar’s L-740Leveling Laser. Since the laser tracker only measuredone point at a time, it required multiple operators andsetups, and took over four hours to measure and adjustall leveling locations. It also had to measure each pointseveral times to verify if adjusting one location hadcaused another to move.Hamar’s L-740, using multiple wireless targetssimultaneously feeding data into a laptop computer(and just one operator), was able to level the fixture in10 minutes Hamar’s system also allowed the levelingprocess to be fully automated by feeding data into thePLC that was driving the actuators and adjustingthe fixture — something that was not possible with atracker. Hamar’s L-740 system did the job 18x fasterthan the laser tracker, and at 1/3 the cost.Adhesive Tape ManufacturingHere’s what a large tape products manufacturer had tosay: “We are getting great results from Hamar’s (L-742)roll alignment system.We trained four technicians howto use it, and they now travel from plant to plant doingalignments. In 10 months, our ROI is 3x, based on thefees we use to pay to optical alignment sub-contractors.And, that doesn’t include all the downtime we’vesaved. Hamar’s system is also more accurate thanother alignment methods we’ve used. Thanks for atop-shelf ‘rubber meets the road’ solution.”Aluminum MillAn ingot-producing machine at an aluminum millneeded aligning, a job normally assigned to an in-houseteam using an optics-based leveling system. Wanting todo the job faster, the mill decided to evaluate Hamar’sL-743 Triplescan™ Laser. Two optics crews workedalongside the Hamar technician using the L-743. Thetask was to align the central ram in the pit to machinerails running parallel along the edge of the pit 15'away, to a tolerance of .005".Hamar’s laser was able to measure five points forevery one the optics crew could measure. Laseralignment did the job in 36 hours compared to thenormal 72 to 96 hours. Using Hamar’s system themill recovered $250,000 in lost production, and ingotquality went up dramatically.123Other DifferencesMachining Center AlignmentHow Lasers Work:Principles of Operation.European Geo.

The dataprovided by the targets is automatically — and instantly — updatedso the machine can be adjusted and the readout will show themovement. When it shows zero, it’s alignedHamar’s multi-plane lasers all feature laser planes that are orthogonalto each other and thus can be used to measure the squareness betweensurfaces or machine axes. In most cases with one setup, the laser canmeasure the squareness between all the axes of the machine tool.Please visit www.hamarlaser.com under “How Lasers Work” for amore detailed description.L-730 Series SystemsHigh-Accuracy,Economically-Priced LaserAlignment SystemsFeatures and BenefitsThe L-730 Series of single, dual and triple-plane laser systems adaptsHamar’s metrology innovations toapplications with less stringent alignment requirements like fabricationalignment, textile roll alignment, wood-working, and the water-jet/laser-cuttingmachine tool industries. You get thebenefits of our high-accuracy laser systems, at a price that is easier to justify.L-730 Series Features:• One, two or three auto-rotating laser planes• Accurate to .00012"/ft or 0.01 mm/M• Laser plane orthogonality:.00012"/ft or 0.01 mm/M• Built-in, backlit level vials with .00012"/ft or 0.01 mm/M accuracy• Dimension measuring capability with target height-gage feature• 3-axis adjustment base for fast setupsIn addition, the L-730 Series lasers feature two target options: a) The A-1532 or A-1533 with a built-inreadout, up to 3" (75mm) measuringrange, and .001" (0.02 mm) resolution, or b) the A-1519 withwireless communication (to PDA),up to 1" (25 mm) measuring range,resolution to .00002" (0.0005 mm) and automatic data downloading intoour machine geometry or surfaceanalysis software.L-730 PrecisionLeveling Laser SystemL-733 Precision Triple Scan®Geometry Alignment SystemLaser System OptionsDifferent applications require different levels of accuracywhich is why we developed two basic families of laseralignment systems:L-730 Series. Ideal for precision-level work but where tolerances are not as critical (e.g. simple fabrication alignment checks, etc.)L-740 Series. Ultra-precise, used for more demanding “mission critical” tasks (e.g. aligning complex machine tool geometry, etc.)Each family of lasers is available in single, dual and triple-planeversions. Many of the features and accessories within the twofamilies are the same. The key difference is the degree ofaccuracy. For example, with the L-730 Series, laser planeflatness is accurate to 2 arc seconds (.00012"/ft or 0.01 mm/M).With the L-740 Series it’s a more stringent 0.5 arcsec(.00003"/ft or 0.0025 mm/M).As would be expected, the tighter the tolerances and greaterthe accuracy level, the higher the price. Accordingly, the L-730Series is an economical choice perfectly suitable for a widerange of alignment applications that do not require theultra-precision attainable in our L-740 Series lasers.L-730 & L-740 Series Features• Live data output to measure — then fix — misalignment,in real time.• Continuously sweeping laser planes with a range of 100'(30.5 m) in radius.• Built-in squareness measuring capability of up to.00006"/ft or 0.005 mm/M (multi-plane lasers only).• Multiple targets displayed simultaneously for fasteralignment and setup.• Collect flatness and straightness data simultaneously.• Work up to 70% faster than interferometers, theodolites,transits and other conventional methods.• Easy to learn how to use, simple to operate.• Able to collect complete geometry data on mostmachines in under 90 minutes.Additional specifications are listed on the back panel, or formore details visit our web-site at: www.hamarlaser.com.L-732 Precision RollAlignment SystemL-740 Series SystemsWhich Laser System Is Right For You?Laser Alignment Systems for Complex,Ultra-Precise ApplicationsFeatures and BenefitsOur ultra-precision L-740 SeriesLaser Alignment Systems representthe pinnacle of achievement in laser alignment technology.
