On March 8th Josh Jones visited The Heim Group in ChicagoIL. The Heim Group manufactures large stamping presses and has a need to productively and effectively clean the steel before it can be welded and painted. The prior cleaning process consisted of using a hand grinder and stone wheel; a 200 square feet sheet was taking 3 days to completely prepare for welding. Using the 2807 Prep/Master outfitted with 50/60 grit 2" stones we were able to completely remove the mill scale in about 2 hours.
