JOTES SPD 40 surface grinding machine

JOTES SPD 40 surface grinding machine was built in 1988 in Poland by PONAR-JOTES Łódź. The machine, designed for precision grinding of workpieces, is an excellent choice for professional production applications. Workpieces placed on a large magnetic plate are ground by means of a spindle with a grinding wheel, which moves transversally and vertically. This solution, combined with the ability to automatically/manually adjust the height of the grinding wheel, significantly increases the accuracy and precision of the machining process. The SPD 40 magnetic surface grinding machine weighs 4800 kg.
