- The mechanical properties of the track shoe for Liebherr undercarriage after heat treatment, usually using CSS44300 universal tensile testing machine
- Surface cleaning refers to steam-cutting wind gun gates, risers, and sand cleaning sand cores with windguns
- Normalizing is mainly to eliminate internal stress and reduce the hardness of the workpiece.
- Surface treatment refers to the sharp corners, burrs, etc. remaining on the surface after the work workpiecepiece is normalized.
- Quenching and tempering are mainly to improve the comprehensive mechanical properties of the workpiece
- Shot blasting refers to the shot blasting after the workpiece is quenched and tempered to achieve a smooth surface.
- The contact position between the track shoe and the wheel body tread and the intermediate stage quenching treatment at the boss
- Processing according to the drawings
- Grinding is to polish the Liebherr track shoes after quenching or quenching, and the smoothing needs to be smoothed.
