Nicolas Correa NORMA MGT

The Nicolas Correa NORMA MGT swaps the rotary table of the NORMA MG for a turning table. Diameter is 1,600 / 2,000 mm, table speed is 250 rpm and the load row reads 6 / 5 Tm. On the NORMA MG the table is square, from 1,250 x 1,250 mm to 2,000 x 2,000 mm, and positions the part; on the MGT it spins the part for turning.

Note the order of the load figures. Diameter is printed as 1,600 / 2,000 mm and load as 6 / 5 Tm, which reads as the larger table carrying less. That is plausible for a table that has to reach 250 rpm at a bigger diameter, but it is worth a direct question. In both cases the rating is below the top of the 5 - 10 Tm range given for the NORMA MG.

Only two machine sizes exist, with X travel of 2,500 mm and 3,500 mm. The NORMA MG adds a 4,500 mm version. Cross travel is 1,250 / 1,500 mm and vertical travel 1,500 / 2,000 mm, each fed at 30 m/min. A 2,000 mm table under 1,500 mm of Y means the spindle works from the rim toward the centre while the table brings the rest of the part round.

The spindle is the one found on the NORMA PIT: HSK-100 T taper, 6,000 rpm, 24 - 33 kW and 840 - 990 Nm. The table makes the difference between the two. The NORMA PIT stops at 1,250 mm of turning diameter, so the MGT is the bed type choice once a part outgrows that.
