The 72780 series is a heavy-duty design abrasive backstand belt grinding and polishing machine for multi-purpose applications. It can be configured with motor rating per spindle from 2.2 to 7.5 kW and is therefore ideal for industrial applications with high stock removal whilst minimizing vibration exposure.
Due to its double-sided design with optional combination of belt grinding and polishing, only belt grinding or only polishing, the 72780 series is a versatile belt grinder machine. Thanks to its robust, low-vibration design, it guarantees a long service life and precise work without shatter marks. The use of heavy cast iron components and welded machine base make it the most durable and strongest belt sander and buffing/polishing jack in the market. The 72780 series has the lowest vibration values ever recorded in any backstand grinder.  Standard sanding belts with a length of 3,500 or 4,000 mm and a maximum width of 100 mm can be used on the machine. The maximum contact wheel dimensions are 450 x 100 mm with a bore of 35 mm. Max. polishing wheel diameter is 500 mm, with special covers up to 1.000 mm.
