Cutting Test Rig HXS 1000-50

The cutting test rig HXS 1000-50 was designed and manufactured by the ASW GmbH Naumburg company exclusively for TU Bergakademie Freiberg in 2008. The rig enables the investigation of the rock cutting process with the use of a big variety of cutting tools and in a wide range of cutting parameters. The installed power of the rig of 60 kW allows the cutting of a rock block (max. 0.6 x 1.2 x 0.5 m in size) with a maximum cutting speed of 1.75 m/s. Four piezoelectric sensors provide the precise measurement of three components of the force acting on the cutting tool (the cutting and normal forces – up to 50 kN, the side force – up to 30 kN). The DEWE 5000 data acquisition system provides the data sampling with a frequency of up to 10 kHz. A high-speed camera might be installed additionally. An in-built laser scanner is used for scanning a profile of the cut face with an accuracy of ≤ 70 µm.

The rig is used for determining the force components while cutting the rock of interest with specified cutting tools and cutting parameters, the volume of cut material, the tool wear, the size distribution of cut chips, dust and noise emissions, etc. As a result, optimum cutting parameters (e.g. providing the minimum specific energy consumption) might be found.
