Metal processing

For the metal processing, sensors are used in order to control or to detect the product itself on the one hand, on the other hand to check the movement of the processing machine. In this process, precision is often less emphasized than huge resistance regarding keen environmental conditions. Concerning the metallurgy, Micro-Epsilon in particular provides various systems in order to be able to check the quality.

Aluminum forge - temperature measurement

Useful, reproducible measurement conditions for infrared temperature sensors are produced during the forming of aluminum by forging or forging presses. The semi-finished products are usually measured after the heating ...

Aluminum – temperature measurement

For aluminum processing, temperatures are measured for the melting, casting, rolling and in many other production steps. Even machine parts which are used in the aluminum industry can be monitored for temperature. Micro-Epsilon ...

Aluminum rolling - temperature measurement

Very different temperatures often occur in the various process stages. The corresponding Micro-Epsilon temperature sensors are used depending on the temperature range and application area.

Tempering - temperature measurement

Stresses can occur during induction hardening which can be counteracted by heating up again to the tempering temperature. However, temperatures lower than those used for hardening are involved. The temperatures are measured with ...

Sheet thickness

It is often the case for sheet machining that sheets must be transported individually in machines. Therefore, it is essential that only one sheet gets into the machine. If two sheets are on top of each other, the process will be ...

Bolts – temperature measurement

Bolts are preheated to 400 °C - 500 °C in order to be pressed easily by the die. Micro-Epsilon pyrometers are used to measure the temperature. Maintenance of the optimum preheating temperature is important in order to ensure a ...

Coil unwinding

Rolled strips in the metal industry are wound on coils for transport. For the later processing when the coils are unwound, it is important to know how much material has already been unrolled. This task is simple to solve by using ...

Coil diameter

Rolled strips in the metal industry are wound on coils for transport. For the later processing when the coils are unwound, it is important to know how much material has already been unrolled. This task is simple to solve by using ...

Coil edge

Rolled sheets in the metal industry are wound on coils for transport. It is important that directly before and also after the coiling, to check the position and the edge condition of the metal strip. optoCONTROL optical micrometers ...

Hardening – temperature measurement

In order to manufacture constant high quality products, the temperature of the workpieces must be precisely measured during the hardening. Non-contact infrared sensors from Micro-Epsilon are suitable for hardening processes due to their ...

Cooling process - temperature measurement

After pressing, the heated metal object is subjected to the cooling process. In order to guarantee a high quality finished product, a controlled cooling rate is necessary. Non-contact thermometers from Micro-Epsilon are particularly suitable ...

Thickness measurement using displacement sensors

Thickness measurement using displacement sensors is a wide application area. Basically there are distinctions between non-destructive/destructive, non-contact/with contact and one-side/two-sided thickness measurement. The Micro-Epsilon measuring ...

Measurement of the zinc strip color in the production plant

In the production of high-quality material strips and boards made out of titanium zinc, the surfaces receive specific treatment. Therefore, the coloring of the zinc products is already determined during the production process.

Strip width when trimming metal strips

As different widths are frequently required during the production of metal strips, the strips must be trimmed after the rolling process and both the cutters must be movable electrically. The distance is now measured by difference measurement using ...

Automatic positioning of synchronizer discs

Synchronizer discs are used as a synchronizer package in automatic transmissions. Behr Systems in Germany created a handling and processing plant for deburring the front side of the synchronizer discs using a laser. An essential part of this plant ...

Double-sheet detection before pressing

To prevent damage, laser-based optical displacement sensors are employed in front of the inlet for profiled sheets in presses to enable the detection of double sheets. The sensors are mounted opposite one another, above and below the passing sheets. ...

Reliable quality control in the rolling mill

One of the profile rolling mills processes profile steel in reversing operation. The rod center is then measured and evaluated using a  optoNCDT 1700-750BL.    

Thickness monitoring in straightening factories

Optical laser displacement sensors are employed in front of the inlet for panels on straightening machines to prevent damage to the machine. The sensors enable the detection of double sheets and an accurate acquisition of upright edges.

Lubrication gap

Sliding bearings are used for crankshaft bearings in the engine. A specific minimum distance is required so that the bearing operates as wear-free as possible. Miniature eddy current sensors are integrated in the bearing for this. They measure the distance ...

Cutting edge measurement

Carbide specialist company Ceratizit uses a semi-automatic measuring machine for production control. This device checks cutting plates for dimensional stability. The cutting plates are moved horizontally for each linear axis and pass through the light beam of ...

Weld seam inspection on pipes

A perfect weld seam is essential in a leak tight pipe. scanCONTROL laser scanners are therefore used during spiral welding to align the weld flanks. This results in a much more reliable welding process. The long base distance of 600mm and the protective housing ...

Extrusion - temperature measurement

Precise temperature measurement at several places is necessary for extrusion: after preheating the bolt, for the discharge of the profile from the die and for quenching the extruded product. An additional check of the tool temperature is usually carried out in order ...

Roller levitation height

The distance of both rollers from each other or from the roller to the support surface is the crucial dimension for rolling processes for metals, plastics or other materials. In the case of sensitive processes and high material accuracies, the lift of the upper roller ...

Roller runout

The runout of the roller is a crucial criterion for rolling processes of metals, plastics or other materials. An imbalance is even dangerous for rollers which have to rotate at high speeds. Therefore, the roundness of the roller must be measured before and also during ...

Roller clearance

The distance of both rollers from each other or from the roller to the support surface is the crucial dimension for rolling processes for metals, plastics or other materials. In the case of sensitive processes and high material accuracies, the clearance must be checked ...
