JOTES SPD 30B surface grinding machine was built in 1978 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 or directly
on the work table are machined by means of a spindle with a grinding
wheel which moves transversely and vertically. The grinding wheel,
driven by an electric motor, reaches a maximum speed of 26 m/s.
The work table, on the other hand, is hydraulically driven and allows
stepless adjustment of the feed rate in a range of 2 to 30 m/min.
Changing the table’s travel direction is done automatically using
stops or manually by switching the appropriate lever. The SPD 30B
magnetic surface grinding machine weighs 5000 kg.
