Enshu SH350

The Enshu SH350 is a compact horizontal machining center with a number 30 spindle taper, built on a floor space of 1,650 x 2,250 mm and weighing 3,500 kg. Travels are 500 mm in X and 400 mm in both Y and Z, the table is 650 x 400 mm and the spindle runs to 12,000 min-1.

The spindle motor ratings say most of what the machine is for. Enshu lists 5.5 kW for 5 min, 3.7 kW for 10 min and 1.5 kW continuous. Those are small figures. They fit drilling, tapping and light milling in aluminium and other easily cut materials, where the tool is in the cut for seconds at a time and the motor works in short bursts. Sustained roughing would run on the 1.5 kW continuous rating, so this is not a machine for taking heavy stock off steel.

The table is rectangular, 650 x 400 mm, and carries 300 kg (661 lb). X travel of 500 mm is shorter than the 650 mm table length, so the outer ends of a long fixture are clamp space, not cutting range. The tool magazine holds 16 tools, or 21 as an option. On a machine doing one operation in a line, 16 tools is often enough; a shop running complete parts will want the larger magazine.

At 2,000 mm high and 3,500 kg the SH350 is easy to place, though door height and floor loading still deserve a check. The larger GE30H gives 500 mm (19.7 in) on all three axes, 60,000 mm/min (2,362.2 in/min) rapids and a 500 kg (1,102.3 lbs) table load. The SH350 table lists no rapid traverse or feed figures.
