L-702/L-702SP Spindle & Flatness Systems

Newly designed, the L-702/L-702SP 4-Axis Spindle Alignment Systems are replacements for our workhorse L-700 Spindle laser that has been used to align spindles in lathes, turning centers, transfer-line and rotary-dial machines for over 20 years. 

Prior Hamar’s spindle lasers, spindles were aligned with indicators and alignment bars, which only measure a short portion of the machine, take a long time to use effectively and are subject to mounting and sag errors. For larger lathes, this makes aligning the entire bed very time consuming. 

The L-702 Spindle Laser comes in 2 configurations:

  • L-702 Spindle Alignment Laser – is a straight-line laser for spindle alignments in lathes, turning centers, OD grinders, slant-bed lathes and transfer-line and rotary-dial machines.
  • L-702SP Spindle Alignment Laser with Scan Plane – this adds a perpendicular scan plane to the L-702 spindle laser beam for checking cross-slide, turret-axis squareness and other milling axes in multi-axis, mill-turn machines.

System Highlights

  • Fast: Easy setups let you 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, allowing the entire length of even the largest lathes to be quickly and easily aligned without changing setups, replacing cumbersome and impractical alignment test bars.
  • Accurate: Ultra-high resolution of .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.
  • Lathe9 Software: Large, easy-to-see alignment displays, live alignment data and spindle graphics, and a 6-step procedure guide users through the alignment with on-screen help instructions.
  • Spindle8 Software: Large, easy-to-see alignment displays, live alignment data and spindle graphics, and a 4-step procedure guide users through aligning spindles to master parts on transfer-line spindle applications.

Key Features

  • The laser and target both offer a .500 in. (12.7 mm) mounting stud for simple fixturing to hold them in place. 
  • Center resolution of .00001 in. (0.00025 mm) and angular resolution of .00001 in/ft (0.0008 mm/m).
  • Live measurement data in 4 axes (V center, V angle, H center & H angle) simultaneously.
  • Windows 7/8/10-based Lathe9 Software with large, color graphics corrects mounting errors, calculates shim values and provides an alignment report showing all the alignment parameters of lathe alignment.
  • Windows 7/8/10-based Spindle8 Software with large, easy-to-see alignment displays, live alignment data and spindle graphics, and a 4-step procedure guide users through aligning spindles to master parts on transfer-line spindle applications.
  • L-702/L-702SP mounts in the spindle to project its axis of rotation out to 100 ft (30 m).
  • Vertical and horizontal angular adjustments  to precisely adjust the laser to the spindle’s axis of rotation.
  • Rechargeable LiPo battery runs the lasers for up to 8 hours.
  • Compact and rugged 4 x 2.9 x 1.7 in. (101 x 74 x 45 mm).
  • Only needs 10 in. (254 mm) of space between spindle and tailstock or sub-spindle.

Complicated Lathe Alignment Checks Done with Ease

Measure headstock spindle-axis parallelism with the lathe-bed and saddle guide-rails, headstock-to-tailstock alignment and spindle-to-subspindle alignment. With a measuring range of up to 65 feet (20 m), even the longest lathe bed is easy to measure for parallelism to the spindle axis, eliminating the need for expensive and heavy test bars.

High Resolution and Accuracy Improves Part Quality

The L-702’s ultra-high resolution of .00001 in. (0.00025 mm) combined with Lathe9 software to correct mounting errors produces a very accurate alignment, less than .0001 in. (0.0025 mm) under good environmental conditions. This extremely high level of accuracy can dramatically improve machine performance and reduce scrap rates.

Measure Cross-Slide or Turret-Slide Squareness with Ease

Use the L-702SP Spindle Laser with it perpendicular scan plan and our A-1519-2.4ZB Single-Axis Scan Target to measure the squareness of the cross slide, turret travel or other axes on multi-turn machines.

Live 4-Axis Data Speeds Alignment by 70%

The T-261A’s 4 alignment values update in real time, so without changing the setup, alignment errors can be quickly fixed, while watching Lathe9 software’s 4-axis display update with each adjustment. Lathe9 software also quickly collects the lathe bed’s straightness data, analyzes it, recommends shim and moves values for headstock and tailstock alignments. In most cases, alignment times can be reduced by 60-70%.

Simultaneous 4-Axis Target

The T-261A 4-axis target measures both the horizontal and vertical center and horizontal and vertical angular readings simultaneously. This combined with Lathe9 Software allows you to see all 4 alignment axes updating as you make mores to the headstock or tailstocki.  This makes checking and correcting the alignment of the lathe’s components much easier and faster.

Alignment Data in 15 Minutes

The L-702 Spindle Alignment System is so easy to set up that you can do a quick alignment check in 15 minutes and the full alignment data in 25–30 minutes on most lathes. Our Lathe9 Software even corrects for mechanical mounting errors to provide the most accurate lathe alignment on the market today!

Lathe9 Built-In, 6-Step Alignment Procedure

An easy-to-follow, 6-step alignment procedure is built right into Lathe9, along with popup instructions, that makes what can be a complicated alignment much simpler and easier to learn. Large color graphical displays allow the alignment data to be seen up to 20 feet (6.5 m) away.
