Features

Horizontal Alignment
Measures and helps correct misalignment while dual sensors maintain the true position of the shafts, even as unintended movements are experienced during the alignment process
Vertical Alignment
Same power and ease of use as the Horizontal Alignment program. The vertical alignment program is used when aligning flanged-mounted machines
Verti-Zontal
Allows for the vertical and horizontal adjustments to be made together in one pass, saving valuable time and ensuring accuracy the first time around
Machine Train
Machine Train routine simplifies the complexity of aligning multiple units with connecting shafts
Flatness
Geometric routines for circular and rectangular flatness across flanged connections, bases, foundations, etc
Straightness
With the Straightness application, straightness can be measured in two axes
Spacer Shaft
The Spacer Shaft program simplifies spacer shaft alignment by showing both ends of the spacer shaft coupling with an angle/angle display
OL2R
Add the OL2R software and patented fixtures to deliver the most accurate measurement of a machine’s thermal growth possible
Cardan Shaft
Using the Fixturlaser NXA equipped with NXA Offset Software together with the Fixturlaser Offset Fixtures, you can precision align any offset mounted machine as fast as you align any other shafts

Quick Tips

Horizontal and Vertical Machines

The NXA Ultimate is perfect for measuring horizontal alignment conditions but its real power is in helping correct misalignment. The dual sensors allow the NXA to maintain the true position of the shafts, even as unintended movements are experienced during the alignment process. The benefit of this “true positon sensing” is that it allows the user to complete the alignment using the Verti-Zontal™ compound move, adjusting in both the vertical and horizontal planes without remeasuring between moves. A Verti-Zontal™ alignment is a great time saver since alignments can be completed in just one or two tries. The NXA Ultimate also comes with a number of utility programs to make the alignment process easier. These include Softcheck™ to control for soft foot conditions, FeetLock™ to deal with base and bolt bound situations, HotCheck™ to calculate the difference between measurements taken in a cold state versus a hot condition, and Target Values, which automatically adjusts the readings to compensate for pre-determined alignment targets based on thermal growth or dynamic movement data.

The same power and ease of use found of the horizontal alignment program can be found in the vertical alignment program. The vertical alignment program is used when aligning flanged-mounted machines.

Machine Train

The NXA’s machine train routine simplifies the complexity of aligning multiple units with connecting shafts. The software includes a “minimal moves” function which identifies the best reference machine to minimize the number of moves required to complete the alignment.

Spacer Shaft

With spacer shafts there are two power planes of transmission that need to be aligned to the correct tolerances. The NXA spacer shaft program simplifies the process showing both ends of the spacer shaft coupling with an angle/angle display. The alignment is completed using the Verti-Zontal™ move.

Shaft alignment

The NXA Ultimate comes with technology enabling functions and capabilities, which in many cases are industry firsts, for example:

  • CCD detectors with ultra high definition resolution.
  • New sensor units with Bluetooth incorporated are the industry’s most compact, yet, they feature a 30 mm detector surface and line lasers.
  • The OmniView™ feature keeps track of the position of both the user and the machine to show the screen display from the user’s perspective, thanks to the built-in gyroscope (6-axis MEMS Inertial Motion Sensor) in the display unit.
  • Ability to keep track of the position of the sensors in both the vertical and horizontal orientation, and any inclination in-between, when performing a shaft alignment, thanks to the built-in gyroscope in the sensor units. Hence, you are then able to perform a shaft alignment on vertically mounted machines where it is not possible to do a 180° shaft rotation.
  • Excellent power management – 10 hours on one charge.

Geometric Measurements

Acoem’s laser-based geometry system is characterized by its user-friendliness and versatility, such as :

  • The graphic user interface is intuitive and 3D animated, with icons and color-coded symbols to guide you throughout the measurement and alignment process.
  • Live values during measurement and simultaneous live adjustment, in both vertical and horizontal orientation (X and Y values), during the adjustment process.
  • Measurement results in micron resolution.
  • Post-measurement evaluation means that you can process saved measurement results in order to choose the best reference. This will result in as few corrections as possible.

Ultimate Measurement Tool for Optimal Operation Conditions

With a mix of shaft alignment and geometry applications, you are safeguarding your machinery’s operation condition. Regular maintenance checks or installations of new machinery, you have what you need in the NXA Ultimate.

Machine foundations need to be checked for any flatness faults, before the machine is actually installed, hence the flatness application. And once installed, the machine’s alignment status must be measured. With everything verified to be perfectly aligned, you can also ensure the machinery’s optimal operation conditions.
