eldec Quality Control – eQC

eldec Quality Control is a package of modules that build on and complement each other. In combination, they guarantee to customers a fully monitored hardening process. The data of the eQC modules can also be saved in relation to the components in the optional process database, which ensures a seamless documentation of process data.

eQC Flux

Measuring inductor base voltage and magnetic flow

eQC Flux monitors both the inductor base voltage and the magnetic flow. By these parameters, a wide range of error sources can be analyzed, such as faulty workpiece geometries or improper materials, and appropriate remedial action can be taken.


Inductor checking and status monitoring

eQC RFID is used before production start to verify if the correct inductor has been inserted for the preselected machining program, and to monitor the tool status. To do so, the system reads important performance data, such as remaining tool life and impending maintenance intervals, from an RFID chip in the tool. After the hardening process is completed, the relevant operating data is written to the RFID chip. For this purpose, a read-write unit is installed in the connection system of the machine. In the event of tool faults or errors, the process will not start again. Information on production tolerances for the inductor can also be included, allowing automatic repositioning of axes if necessary.

eQC Quench
Viscosity monitoring of quenching medium

The quality and stability of the hardening process are also greatly influenced by the condition of the quenching medium. It changes during the process, since the polymer chains it contains will gradually break up under the influence of light and heat. The quality of the quenching medium must therefore be checked regularly. At present, this is often still done by measuring the light refraction index. However, this does not indicate the condition of the polymer chains and is therefore inaccurate. The testing method offered by eldec is based on an ultrasonic sensor that continuously monitors the viscosity of the quenching medium, and provides very precise information regarding its quality.
