L-703 Bore & Spindle Alignment Laser System

Our newest laser, the L-703 Bore & Spindle Laser Alignment System is small, compact, highly accurate and simple to use. It can be used on a wide variety of applications from bore alignment to spindle alignments.  It features a .500 in. (12.7 mm) mounting stud for easy insertion into spindles or into our L-112 Laser Stand for bore alignments.  It has 4 alignment kit options for various applications:

 

System Highlights

  • Fast: Do a quick alignment check in 15 minutes and get full alignment data in 25-30 minutes on most machines.
  • Easy: Laser and target mount directly into the spindle and tailstock, respectively, or in laser/target stands, allowing the entire length of even the machines to be quickly and easily aligned without changing setups, replacing cumbersome and impractical alignment test bars. 
  • Versatile:  The L-703 can be combined with different targets and fixturing for other applications, such as bore alignment and guideway straightness applications.
  • Accurate: 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.
  • Time Saving Fixturing:  We have several laser and target stands for various applications, making the laser easier to set up and speeding up laser buck-ins.
  • Bore9 and Lathe10 PC-Based Software: Large, easy-to-see alignment displays, real-time alignment data, machine graphics, and a 6-step procedure guide users through the alignment with on-screen help instructions.

Key Features

  • L-703 Laser and T-1295 Target both have a .500 in. (12.7 mm) mounting stud for simple fixturing to hold them in place. 
  • T-1295 5-Axis Target offset resolution is .00002 in. (0.00025 mm) and angular resolution is .00008 in/ft (0.007 mm/m).  High-resolution T-1296 5-Axis Target has 2x higher resolution and accuracy.
  • Real-time measurement data in 4 axes (V center, V angle, H center & H angle)
  • Windows 7/8/10-based Bore9 and Lathe10 Software with corrects mounting errors, records data, calculates shim values and provides an alignment report showing all the alignment parameters of lathe alignment.
  • L-703 mounts directly in the spindle collet or chuck to project its axis of rotation out to 50 ft. (30 m).  A long-distance version is also available.
  • Laser beam is centered to mounting stud to <.0005 in. (0.013 mm).
  • Vertical and horizontal angular adjustment resolution of .00002 in/ft. (0.0017 mm/m)
  • Optional L-103 Optical Laser Beam Translator can precisely position laser to rotation axis or bore center to .0001 in. (0.0025 m).
  • Rechargeable Li-On battery with 11-hour battery life for laser and targets.
  • Only needs 5.6 in. (142 mm) of space between spindle and tailstock or sub-spindle.
  • 15-minute setup time. 
  • Combine the L-112 Laser Stand and A-510 & A-221 Self-Centering Bore Targets for many different bore alignment apps as well as guideway straightness applications.

L-703 Ideal for Spindle Alignment

The L-703 Bore & Spindle laser is ideal for measuring spindle alignment on lathes, turning centers and ID/OD grinders. Combined with our T-1295 5-Axis Wireless Target and Lathe10 software, the L-703 is a quick and very accurate tool to quickly check spindle-to-subspindle alignment, headstock spindle axis-to-guideway alignment and guideway flatness/straightness.

T-1295/T-1296 5-Axis, Wireless, Multi-Purpose Scan & Spindle Target

The T-1295/1296 5-Axis, Wireless, Multi-Purpose Scan & Spindle Targets have up to .00001 in. (0.00025 mm) resolution and high accuracy for extremely accurate spindle alignments.  Insert an angular optic and the targets measure the angle of the rotation axis relative to the laser, all in real time so realignment is fast and easy.  Switch to Scan Mode and the T-1295/1296 can be used with any of our autorotating lasers.  Bluetooth communication with the PC means data recording is fast and easy.

Simple Fixturing for Fast Setup

The L-703 Laser has been designed with a .4995 in. ( 12.69 mm) mounting stud that can easily be chucked up into a spindle or fits into our L-112 Laser Stand.  The laser beam is concentric to the stud OD to within .0005 in. (0.013 mm).  A simple fixture with a .500 in. (12.7 mm) hole is all that is needed to hold the L-703 in place.

Wide Angular Adjustment Range

The L-703 Laser has an angular adjustment (pitch/yaw) range of ±0.36° (± .075 in./ft or ± 6.3 mm/m) and a resolution of .00002 in/ft. (0.0016 mm/m).  It can be used on applications up to 50 feet (15 m), such as compressor, engine blocks, cylinders and twin-barrel extruders.

Add Bore Alignment Targets

The L-703 can be packaged with our L-112 Laser Stand and our patented, self-centering targets to offer one of the most accurate bore alignment systems on the market.  The ultra-precise L-703  Laser means accuracies down to .0002 in. (0.005 mm) in 10 feet (1 m) are no problem for the L-703 Self-Centering Bore Alignment System.

Patented, Self-Centering Target Bore Adapters

Hamar Laser has developed the world’s first self-centering targets (A-510, A-512, T-220, T-221, T-1240) and bore adapters (A-510STA/A-510LTA, A-512STA/A-512LTA, A-514A/B/C, T-221STA) that use no moving parts to self center in a bore. It takes just seconds to position the target in the barrel for an accurate measurement down to .0002 in. (0.005 mm).  This eliminates the annoying 0 and 180 measurements needed for typical bore targets.

Guideway Straightness & Flatness

Package the L-703 with the L-112 Laser Stand, L-702MB Mag Base Fixture and T-1295/1296 Target and the L-703 can be used for aligning rails or guideways during assembly of machine tools to a very high accuracy.  It will even measure pitch and yaw angular errors!  Ultra fast setups and real-time alignment data means the rails are aligned in no time!
