THE FUTURE OF ON SITE MACHINING Cutting Machine for Heat Exchanger Tubes Standard Capacity: 59.05" - 118.11" (1500mm - 3000mm) The machine is used during the heat exchanger manufacturing process when they pass the tubes across the tube sheet. The tubes that are not the same length out of the tube sheet will be cut to 0.197" (5mm) from the tube sheet. The tubes are not clamped on the tube sheet, there is a small gap of 0.0039" (0.1 mm). The machine is based on a frame of XP machine but without a machining head. It uses two milling heads with saw blades. The arms with milling heads perform the cut of all the tubes on the same tube sheet with a 180° rotation. After the cut, a PROTEM SM8 is used to face the tubes precisely. By hand (with a grinder), they needed more than 3 days to make all the cuts and now, with the machine, less than 1 day is enough.
