Monitoring the clamping position in machine tools
clamping position in machine tools is an extremely important and critical
measurement task. In order to avoid incorrect machining and the high resulting
costs, the position of the tool must be detected. Here, the induSENSOR LVP
displacement sensor is used. This compact and wear-free sensor supplies a
continuous analog signal according to the stroke motion of the drawbar when clamping
In modern machine
tools, the tool is normally changed fully automatically. When changing the
tools, the machine automatically removes the appropriate holder and places it
on the spindle whose clamping system locks the holder in position. If the tool
is incorrectly positioned, this can lead to faulty processing. If the tool is
tilted, the worst case scenario is that it can loosen which would result in
high machine damage.
In order to avoid damage and processing errors, it is necessary to monitor the tool position. Often, initiators and switching rings are used for monitoring tasks. However, these are difficult to adjust. With the inductive induSENSOR LVP displacement sensor, Micro-Epsilon offers a significantl...
In order to avoid
damage and processing errors, it is necessary to monitor the tool position.
Often, initiators and switching rings are used for monitoring tasks. However,
these are difficult to adjust. With the inductive induSENSOR LVP displacement
sensor, Micro-Epsilon offers a significantly easier and more reliable solution
based for continuous monitoring of the clamping position. The cylindrical
sensor is integrated into the release device of the clamping system. A ring,
which serves as a target for the sensor, is simply glued onto the drawbar. Due
to its compact size, the LVP sensor can be integrated in different tool types.
In addition, it’s a long-life device as measurements are performed on a
non-contact, wear-free basis.
The sensor enables continuous monitoring of the clamping position and supplies an analog signal according to the stroke motion of the drawbar when clamping the tool. Therefore, it is not necessary to laboriously set the switching point mechanically. The miniature sensor controller can either be accommodated at the point of measurement or in the control cabinet.
Together with the induSENSOR MSC7401 controller, this measuring system provides a favorable price/performance ratio at high resolution combined with ease of use.

How measurement sensors improve the performance of tooling machines
Faster, more precise, higher productivity - these are the key requirements when developing new machine tools. In many cases, improvements can only be achieved using sophisticated sensor technologies. Micro-Epsilon demonstrates this with a wide range of applications that are ideally suited to the machine tool industry.
A Comparison of Blue and Red Laser Triangulation Sensors
Red laser sensors have been in use for over 20 years now and are known to perform well and have improved in recent years to provide good measurement stability on a wide range of dynamically changing surfaces, including low reflectivity and matt surfaces, as well as on fast-moving objects. However, on certain materials, red laser sensors perform less well. So when is it best to use a blue laser triangulation sensor over a red one? To answer this, a number of factors need to be considered.
Learn Why Eddy-Current Sensors Are Now Replacing Inductive Sensors and Switches
Both eddy-current sensors as well as inductive switches and displacement sensors have been used for many years, each having their respective advantages when it comes to measuring position and displacement of objects in harsh environments. However, recent advances in eddy-current sensor design, integration and packaging, as well as overall cost reduction, have made these sensors a much more attractive option. This is especially true where high linearity, high-speed measurements and high resolution are critical requirements.
How to Reach Unrivaled Precision in Distance and Thickness Measurements with Confocal Sensors
Confocal chromatic measuring systems are increasingly used for fast distance and thickness measurements. Different sensor and controller models open versatile fields of application, e.g. in the semiconductor industry, glass industry, medical engineering and plastics production. The unique optical confocalDT measurement system from Micro-Epsilon is based on the optical measuring principle, which specifically takes advantage of the so-called chromatic aberration of light. This refers to the different refraction of light in relation to its wavelengths. It measures distances by means of wavelength (spectrometry).
Non-contact temperature measurement of plastics
In plastics processing where thermal processes play a particularly important role, temperature is the crucial measurement parameter. Only precise temperature control ensures high, consistent product quality. Micro-Epsilon provides suitable measurement technology from a single source for almost any material or polymer.
Learn how capacitive sensors open up new perspectives
Conventional capacitive sensors are known from simple tasks e.g. as proximity sensor or for fill level measurements. With corresponding design and evaluation electronics, these sensors can also be used for high precision displacement and position measurements, achieving resolutions well below one nanometer. Capacitive displacement sensors are typically used in applications where fast displacement changes have to be acquired, where no forces can be exerted on the measurement object, where highly sensitive surfaces do not allow any contact, or where a long service life of the sensor is required. Capacitive displacement sensors from Micro-Epsilon have proven themselves in various industries and measurement tasks.
