The Marsurf UD 120 roughness profile measuring instrument is randomly equipped with the XCR 20 CNC software package, providing a wide range of measurement and evaluation functions, especially for profiles and roughness. The drive shaft and column lifting shaft can be controlled by sitting on the same operating lever or through program control.
·Explanation
-Complete roughness and contour evaluation in one measurement
Less time, faster operation, more reliable results, and more efficient work, all roughness and contour parameters can be obtained with just one measurement. Leave you more time to complete other tasks!
-The most modern conversion technology is more suitable for small tolerance workpieces
Due to the device's ability to achieve high-precision measurements with high resolution over a large measurement range, you can leave smaller allowable errors for your machining tasks and take on new challenges.
-Innovative arm movement concept achieves maximum stability
The mobile measuring arm adopts a bridge structure design, ensuring maximum rigidity, minimum measurement vibration, and flatness; In this way, during use, you can construct bridge structures of any size!
-Magnetic suspension bracket for measuring arm
Magnetic installation design can ensure high-frequency use of the system, collision safety protection, and achieve long service life.

·Components of the measuring station
Drive MarSurf UD 120/LD 120
The Marsurf UD 120/LD 120 driver can easily achieve a measurement stroke of 0.1mm to 120mm, with speed control within 0.1 to 2mm/s. Due to the high-precision grating ruler used on the X-axis, automatic positioning can be achieved.
·Working principle of probe system
The working principle of the probe is based on a joystick system with a measuring tip, and the other end of the joystick is a diffraction grid, which can measure the swing angle of the joystick. The light emitted by the light-emitting diode shines on the diffraction grid, producing an interference pattern. The rise and fall of the measuring tip will cause changes in the interference pattern at the receiving end, and the subsequent evaluation circuit can determine the position of the grid, which in turn determines the position of the measuring tip.
A mobile rotary motor is used for Z-direction probe positioning to determine the direction of probe movement and achieve force control.
To meet most common applications, the Marsurf LD120 probe set is equipped with LD A14-10-2 90 ° by default, LD A14-10-500 (LD 120), Several measuring arms, including LD A14-10-2 60 ° (UD 120). The rigid skeleton structure of the measuring head ensures high linearity, high accuracy, and high reliability during measurement.
In order to meet other different measurement tasks, there are various geometric sizes of measuring heads and tips available for selection. Depending on your measurement task, you can use a 2 μ m diamond measuring tip for roughness measurement, a 25 μ m carbon steel measuring tip for contour measurement, or a ruby measuring ball. By using these different probe selections, both short wave and long wave profile components can be recorded and evaluated after a single measurement.

Simple and accurate arm replacement on MarSurf UD 120/LD 120
For most workpieces, standard measuring heads can be used to measure contours and roughness at various measurement positions. However, not all measurement tasks can be completed with one measuring arm, such as measurements in small holes, measurements in deep grooves, bidirectional measurements, and other measurement tasks. At this point, replacing the measuring arm is also very simple. No tools are needed, the magnetic clamping measuring arm can be easily removed by hand and replaced with another measuring arm in just a few seconds. A spherical locator can ensure precise positioning in micrometers.
As long as the replaced measuring arm has been calibrated, the calibration parameters have been saved, which means that there is no need to recalibrate after replacing the measuring arm!
From the perspective of easy operation and time-saving, this is a substantial advantage of Marsurf UD 120!
