Complete system for measurement and alignment of machine tools

Easy-Laser® E940 Machine tool system is the market’s most complete measurement system for measuring and aligning machine tools. You can measure straightness, flatness, squareness, spindle pointing direction, level and much more.
The transmitter's laser beam can be compared to an absolutely straight and weightless ruler, that is to say a perfect starting point for precision measurement. The measurement programs guide the user step-by-step through the measurement process* with clear graphics and instructions on the large 5.7” colour display. It is also possible to use the measurement values directly and measure and adjust as required.

Measures all kind of machine tools

The system can handle most tasks in this field, despite the fact that there is considerable variation in machine design: different types of lathe, milling machines, automatic drills, presses, water cutting machines etc. Some examples of what you can check:

  • Straightness of machine axis 
  • Spindle direction 
  • Spindle to spindle/tail stock 
  • Squareness between machine axis
  • Flatness on machine table or machine bed
  • Bearing play check
  • Bearing condition (g)

A laser system is a profitable investment

Compared to conventional methods, such as dial gauges, mandrels and stones, work can be carried out much more quickly using a laser measurement system. And don't forget, the measurement result can be documented and compared to ISO10791-1 and 10791-2 used for machine tools. There are lots of good reasons for investing in a laser system. One is that, because it is so quick to set up, the operator can check a machine much more often - if there has been an accidental collision in the machine for example. Then compare with the machine documentation to see if everything is ok before continuing production. This can prevent costly production of parts that are out of tolerance. It can also extend the life of the tools. 

0.0001 mm HyperPSD™ resolution

With Easy-Laser® E940, the user can perform almost any kind of measurement thanks to the very versatile design of the D22 laser transmitter, the measuring units and brackets. For example, the measuring unit can also act as a compact and light-weight laser transmitter. Mounted on the cleverly designed spindle bracket it can even point the laser through the clamping pin, through the spindle. The measuring units delivered with this system have our new HyperPSD™ precision detectors, making it possible to display a resolution of 0.0001 mm [0.000005”/0.005 mils].

  • Light and easy-to-use equipment = shorter time for preparations and measurements
  • Possible to measure and align at long distances = greater accuracy
  • Possible to measure both X and Y (Z) directions at the same time = saves time
  • The reference (laser beam) is always 100% straight
  • Possible to document the measurement results as PDF and transfer to a PC

PROGRAMS AND FUNCTIONS

The key to a quick and reliable measurement are programs that guide you through the measurement process. The Easy-Laser® systems support you with smart functions and a clear user interface. Still, it is not our products that do the job, but you as a professional technician!
image description

Machine Train

Regardless of what machines you have and in which order they were assembled, you can build your own machine train with theoretically as many machines as you like. You can pick the reference machine manually, or let the program choose one that will minimize the need for adjustments. 

image description

VERTICAL/FLANGE MOUNTED MACHINES

This program is used for alignment of vertical and flange-mounted machines, e.g. pumps, motors, gear boxes. Shows centre offset, angular error and shim value at each bolt.

image description

VALUES - DIGITAL DIAL INDICATOR

The Values program can be used e.g. when one wants to measure as with dial gauges and to check bearing play or shaft load. With the standard equipment and completely normal set up on the machine!

image description

CARDAN/OFFSET MOUNTED MACHINES

Alignment of cardan/offset mounted machines. (Accessory Cardan fixture, Part No. 12-0615 is required.)

image description

BELT ALIGNMENT

Using the system you can align sheaves and pulleys with digital precision. Adjustment of the machines is displayed in real time on the screen, with readings for angle and axial displacement in both the vertical and horizontal axes, as well as an adjustment value for the front or rear foot pair. The result can be documented as normal. (Requires the E180 BTA accessory.)

image description

VIBRATION MEASUREMENT

The Vibration Measurement program allows you to measure vibration levels (mm/s, inch/s) and bearing condition (g-value). The program guides the user through the vertical, horizontal and axial points to measure on the machine. The result can be documented as usual. (Requires the E285 Vibrometer probe accessory.)

image description

SOFT FOOT CHECK

Alignment work begins with a soft foot check. The soft foot check ensures that the machine is resting evenly on all its feet by indicating which foot/feet should be adjusted. This is an important part of securing a reliable alignment. After the soft foot check is com- plete, you can go directly to the alignment program with all of the machine’s distance values saved.

image description

EASYTURN™ FUNCTION

The EasyTurn™ function allows you to begin the measurement process from anywhere on the turn. You can turn the shaft to any three positions with as little as 20° between each position to register the measurement values. Voila! Measurement is complete!

image description

Result table

The result table shows how well your readings repeat and lets you save comments for each one.

image description

MEASUREMENT VALUE FILTER

An advanced electronic filter function can be used to achieve reliable results even under poor measuring conditions. Air turbulence and vibrations from adjacent machines are no match for the Easy-Laser® filter function!

image description

STRAIGHTNESS MEASUREMENT

With our program for measuring straightness, you can easily measure long shafts, rolls, bearings, bases, machine structures etc. All you have to do is define a number of measuring points, in advance or while measuring. You will be able to get the result for both the horizontal and vertical alignment, graphically as well as digitally.

MEASURING UNIT ES-H / EM-H

Laser diode and PSD detector in one compact housing. In system E940 these units have got the HyperPSD™ technology. This makes it possible to display a resolution of 0.0001 mm [0.000005"/0.005 mils]. The units have 2-axis PSD which reads the position in two directions at the same time.

For alignment of two to each other pointing shafts both units, EMH and ESH, are used.

The EMH-unit is used as detector when measuring with a separate laser transmitters, but then without turning the laser on. Most common is to mount the unit on a magnet base (see D to the right).

The ESH-unit can act as a laser transmitter (see E), and together with the spindle bracket be used for measurement of pointing direction. The laser beam can be pointed through the clamping pin (F), making it possible to align bar feeders for example.

The Bluetooth® unit for wireless communication is compact and makes the measurement work easier than using cables, especially when rotating the units in the spindle.

The measuring units conform with IP class 66 and 67.
