Measurement and Testing

There is a CMM device in order to determine the measurement accuracy of the parts produced in MEGEM. WENZEL brand LH 1512 model CMM device (Figure 3) performs measurements of parts with maximum dimensions of 1400x2000x1200 mm and a weight of 3500 kg.

In the test laboratory, there are tensile, charpy impact test, vickers hardness measurement, microscope and spectral analysis devices. In addition, the necessary sample preparation tools are also available in the laboratory in order to prepare suitable parts for test equipment. The tensile test is performed on the Alşa brand MCK 600 model device (Figure 4). It can apply tensile force up to 600 kN. The tensile tester has hydraulic clamping. Round materials with a diameter of 6-40 mm and flat materials with a thickness of 0-30 mm can be connected to the test device. The tests that can be performed on the device are tensile, compression, bending, holding in the load.

Şekil 5. Alşa 300J Çentik Darbe Test Cihazı

For the charpy impact test, the Alşa brand 300J (Figure 5) model is located in the laboratory. The fall speed of the test device is 5.5 m/s, and the fall angle is 160°. Thanks to the cooling cabinet in the laboratory, experiments can be carried out down to -40°.

There are macro and micro hardness testers to measure the hardness of the parts. The macro hardness tester is the Duroline-V (Figure 6) model of the Metkon brand. It measures hardness using the Vickers method. The device can measure the vickers hardness of products under a load of 1,2, 3, 5,10,20,30 kg.
