MEAX MT20  – Effective checks on turning centres

MEAX MT20  – Effective checks on turning centres

With MEAX MT20 you can carry out a full check of the geometric status of a turning centre in less than 30 minutes. The instrument measures the machine's geometry and movements in four simple steps.
The tailored software takes you through the measurements, allowing MEAX MT20 to be used by anyone. The measurements are performed with four sensors wirelessly connected to the MEAX display unit, which displays the result directly. The measurements are saved and can then be transferred to create additional documentation.
MEAX MT20 sensors are high-precision instruments and will provide accurate measurements down to 0.001 mm.
The complete system comes supplied in a small robust case which is easy to carry around with you.

Machine tool measurments with instant results and high accuracy













STREVEL- Check machine's movements and geometryiStraightnessAndLevel


To check that the machine’s movements run straight without any pitch and roll, a solution with multiple sensors is required.
The MEAX LR sensor is positioned on the machine bed and the LM sensor is fitted to the tool holder using the attachment supplied. The SR sensor is mounted in the main spindle and the MEAX SM sensor in the tool holder.
The result is displayed as a set of measured points along the length of the movement.
In this way MEAX MT20 checks the straightness of the machine’s movement, at the same time as measuring the angular deviation of the movement in relation to the machine bed. The result is displayed in both graphic and text form, and can easily be exported via USB.


Spindle Alignment

Measuring turning of the machine centres
Because deviations in spindle alignment impact on the machined part, it is
important that this can be easily measured.
You check the deviation via four measured points in two positions along the Z axis.
By rotating the laser in the spindle and moving the MEAX SM sensor along the Z axis, you obtain result for parallel alignment between the rotational axis of the spindle to the 2-axis movement. The results are displayed in graphic form in two directions: at square and parallell to the machine bed and in parallel with it.

Measuring and adjusting the tool holder
Using the MEAX SR and SM sensors, you can measure alignment
between the main spindle and the tool holder to quickly set a zero point in the tool holder.
The measuring instrument guides you through the entire measuring
process. The software shows you how to take measurements in four
rotation positions and then calculates a result that shows the angular error and centre deviation between spindle and tool holder. Adjustments can then be made in the live function unique to MEAX.



Measuring machine squerenessiSquareness

Measuring squareness
By fitting a prism to MEAX SR, you can measure whether the machine’s movements are square with each other. The measurement is performed in two steps: first by measuring the X axis and then the Z axis. The software helps you perform the measurement; you will see the angle deviation
directly. The customized fixture makes it easy to fit the sensors, thus
ensuring a correct result.
