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.

Bending/smoothness of Aluminum cast covers

After AL covers have been cast and prior to milling of the sealing surface the covers must be manually straightened and sorted into OK/NOK. This operation takes place in a rough environment (casting bay). ...

Non-contact thickness measurement of aluminum

For the prompt detection of incorrect thickness on aluminum strip, patented laser triangulation sensors are employed as a modern alternative solution to isotope measurement systems. To save costs the places ...

Aluminum rim dimension

Maximum quality is required for the production of aluminum rims so that the necessary smooth running is achieved in the subsequent use. In contrast to tactile methods, laser scanners from the 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 ...

Measuring system for strip position monitoring in a coating tank

In the electrolytic refinement of thin sheets electrical losses are minimised by a small distance between strip and anode. This requires exact strip guidance. Before the strip enters the coating tank it ...

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 ...

Sheet edge measurement prior to laser welding

The company „Paul von der Bank“ in Hilden (Germany) develops and manufactures modular-designed robotic welding cells and fully automatic production and processing lines. To ensure high production quality ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 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 ...

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 ...

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 ...

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 ...

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 ...

Damage prevention during production of locking cylinder

The company Aumat (Germany) develops and produces complex production systems for locking cylinders. In order to prevent any damage occurring, the operator must feed the correct blank into the production ...

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 ...

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 ...

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. ...

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 ...

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 ...

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, ...

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 ...

Flatness measurement in rolling mills

The requirements on the surface quality of rolled sheet metal are continually increasing. This may be steel sheet which is used, for example, for stainless steel fronts in kitchens, or also aluminum sheet ...

Angle

It is important to know the angle of a surface for many processes. Contacting measurement is not expedient in automated processes. scanCONTROL 2800 or scanCONTROL 2700 non-contact sensors measure any angle ...
