PONAR TARNÓW RUP-28 universal grinding machine

PONAR TARNÓW RUP-28 universal grinding machine was built in 1979 in Poland by the Fabryka Obrabiarek Specjalizowanych Ponar-Tarnów. The machine is used for precise grinding of both external and internal cylindrical surfaces in order to achieve the appropriate class of surface roughness and the desired shape. The grinding process is performed on a large work table by means of a grinding wheel that reaches a speed of 45 m/s. The machine’s design has been developed to ensure the highest stability and accuracy of the performed operations during many years of intensive use. All this makes the offered RUP 28 cylindrical and internal grinding machine an excellent choice for production plants, tool shops or workshops specialised in the reconditioning of machine parts. The total weight of the machine is 2600 kg.
