A-510 2-AXIS SELF-CENTERING BORE TARGET

DESCRIPTION

The A-510 Target is a general-purpose, 2-axis bore target comprised of a target and an insertion pole. It is used with customized adapters to measure bores from 1.5" to 18" (40 mm to 450 mm). The adapter can be attached to the target in either Self-Centering Mode or Measurement Mode. In Self-Centering Mode, the target automatically centers itself in any bore size that is +/- .060" (1.52 mm) from the adapter bore diameter. It self-centers by carefully centering the target PSD cell axially between the feet. This puts the target cell on the pivot point and allows it to vary by up to 45º without affecting the center. The adapter is actually slightly larger than the bore, so when it is inserted in the bore (by pulling on the cord and tipping it forward) and the cord is released, it "jams" in the bore, centering itself.

In Measurement Mode, the target will measure the bore diameter. First, a reference diameter is measured with an inside micrometer. The target is placed in the reference bore and the reading is noted. The target is then inverted and the readings averaged to calculate the target centering error. The corrected reading becomes the benchmark diameter. Subsequent measurement points in the bore are compared to the benchmark and the difference in target readings is the increase or decrease in bore diameter.

APPLICATIONS

• Any bore application with minimum of 1.5" (38 mm) diameter
• Extruders-single or twin barrel
• Boring bar bearing supports
• Engine block crankcase bores
• Cylinder bores

FEATURES

• Self-centering, 2-axis target accurate to .0005" (.013 mm) with a resolution of .0001" (.0025 mm).
• Measures bore straightness in Self-Centering Mode, or bore diameters in Measuring Mode.
• Tips on adapter feet use hardened carbide steel balls that rarely wear out.
• Target with adapters can handle diameter variations of +/- .060" (1.52 mm).
• Rugged, portable and very lightweight.
• Uses the following bore adapters:
  - A-510A 2" to 4" (50 mm to 100 mm)
  - A-510B 4" to 8" (100 mm to 200 mm)
  - A-510C 8" to 12" (200 mm to 300 mm)
  - A-510D 12" to 18" (300 mm to 450 mm)

A-511 WAND BORE TARGET

DESCRIPTION
The Model A-511 Wand Bore Target is a single-axis, micrometer-adjustable target designed for measuring the center of large bores. It uses a fixture with two legs: a measuring leg, with an adjustable measuring tip, and a brace leg that is perpendicular to the measuring leg and ending in a T-shaped tip. The legs are supplied by the user, made from hollow steel tubing and cut to a length so that the distance from the tip of the measuring leg to the target center is approximately equal to the radius of the bore. The target's micrometer provides the fine centering adjustment. The target head swivels to face the beam regardless of its direction, and the unit has a ten-foot cable that can be used with target extension cables to fit any size bore or working environment.

To take bore alignment readings, the A-511 is set horizontally to the same side of each bore to be measured and is "zeroed out" using the micrometer. For vertical center measurements, the target measuring leg is then positioned vertically and the bore center measurement is taken by sweeping the target through "top-dead center". For the horizontal measurement, the target measuring leg is set horizontally to the side opposite where the target was "zeroed out". To find "top-dead center" the A-511 is swept though the "high point"; in other words, the target is moved toward and away from the laser, along the centerline, and the highest reading is recorded.

APPLICATIONS

• Turbine and other bore alignment

FEATURES

• Light weight and capable of measuring bore radii from 6" to 48"+ (150 mm to 1.2 M).
• Fast set up with very repeatable measurements.
• .0001" (.0025 mm) resolution.
• Provides live measurement data to show alignment moves as they are being made.
• Uses standard, easy-to-locate conduit for measurement and brace legs.
• Comes with 3 measurement tips for variations in measurement surface. Each tip has 4" (101 mm) of adjustment range.

T-212 4-AXIS TARGET

DESCRIPTION

The T-212 4-Axis Target is a general-purpose target that provides both 2-axis centering and squareness (pitch and yaw) measurements. To switch from center mode to squareness mode, a precision lens (1" focal length) is inserted into the face of the target. The target is extremely useful for aligning headstocks to tailstocks on lathes, measuring squareness on machining centers and aligning spindles in transfer lines. It can be used with the L-700, L-705, L-720, and L-720M lasers. A .500" (12.7 mm) diameter stud at the rear of the T-212 allows easy mounting and simplified fixture design.

APPLICATIONS

• Rotary dial machines
• Vertical and horizontal machining centers
• Lathe alignment
• Printing press side frames
• Transfer-line spindle alignment
• Boring-bar bearings
• Bar feeders

FEATURES

• Fast, easy 2-axis measurement of both center and angle with one setup.
• The .500" (12.7 mm) diameter stud allows easy mounting and simplified fixture design.
• Can be used with the R-307 Dual-Axis Readout, the R-307V Large LED Dual-Axis Readout, the R-355 and
  R-358 Computer Interfaces and with future readout designs.

T-218 UNIVERSAL"SEE-THROUGH" TARGET

DESCRIPTION

The T-218 Universal Target is a two-axis, "see-through" target designed for multiple-target, centering applications, like turbine or other large bore applications. A small mirror directs the beam to the target cell that is 90º to the centerline; this mirror can be flipped out of the way to allow the laser beam to pass through the target body without optical interference. The T-218T can be used with the T-225(L) flange(s) adapter(s), tooling sphere, turbine mounting fixtures, the T-230 target stand, or custom fixtures. Used with the L-700, L-705, and L-720M lasers. T-218T has an adapter flange for turbine alignment applications.

APPLICATIONS

• Turbine Bores
• Hinge Lines
• General Bores, large and small
• Cam/Crankshaft/Cylinder Bore Alignment/Inspection
• Bar Feeders

FEATURES

• "See-through" target with small mirror that flips out allowing the beam to pass entirely through the target.
• Compatible with the R-307 Dual-Axis Readout, R-307V Large LED Dual-Axis Readout and the R-355/R-358 Computer Interface and with future readout designs.
• Three flanges adapter for bores, centerlines, and tooling spheres make designing and building fixtures easy.

T-261A SIMULTANEOUS 4-AXIS SPINDLE TARGET

DESCRIPTION

The T-261A Four-Axis Spindle Target has the most angular sensitivity of any Hamar Laser target. It reads both center and angle (pitch and yaw) simultaneously, allowing a real-time display of alignment. Readings are accurate to .0001"/ft. (.0083 mm/M) in angle mode and .0001" (.0025 mm) in center mode. Two levels, top and bottom, provide easy indexing when inverting the target for error correction readings. The standard .500" (12.7 mm) mounting stud simplifies fixture design, and removes easily for attaching custom mounting hardware.

The T-261A can be used in a wide range of alignment/measurement applications. For use with L-700, L-705, L-720 and L-720M. For the most efficient alignment, we highly recommend that the T-261A be used with the R-355/R-358 Interfaces and Spindle 8 Software; although it can be used with two R-307 Dual-Axis Readouts or two R-307V Large-Number LED Readouts.

APPLICATIONS

• Transfer Lines (Spindle)
• Rotary Dial Spindle Alignment
• Turning Applications (Cylindrical, OD/ID Grinders, Lathes)
• Machining Centers with L-720(M) (HBM, VBM, VTL, VMC, HMC, Gantries, Surface Grinders)

FEATURES

• Simultaneously measures 4 axes - horizontal and vertical center and angle (pitch and yaw).
• .0001"(.0025 mm) center resolution and .0001"/ft (.008 mm/M) angular resolution.
• When used with Hamar Laser's computer interface and software, the T-261A. Provides continuous, real-time information to a "live" graphic display that enables the user to see changes and adjustments in all 4 axes as they are made.
• Two levels, top and bottom, provide repeatability in rotational positioning when performing the NORMIN procedure.
• The .500" (12.7 mm) diameter mounting stud simplifies fixture design and building and can be easily replaced with custom mounting fixtures.
