PAMA Speedmat

The PAMA Speedmat is a T-type boring and milling center: the table travels on X in front of a column that moves toward it on Z, and the headstock climbs the column on Y. Unlike the maker's floor-type machines, the workpiece sits on a rotating table that is part of the machine, which makes four-sided machining in one clamping the normal way of working.

The table defines the size. Swing diameter is 2,200 - 5,000 mm. Milling tables or pallets run from 1,250 x 1,250 to 3,000 x 3,000 mm and carry up to 50,000 kg, on a hydrostatic rotating B axis with rapid feed up to 6 rpm. Travels are 2,200 - 5,000 mm in X, 1,750 - 4,000 mm in Y and 1,500 - 4,000 mm in Z.

Three headstocks are tabulated, and the choice sets the character of the machine. The W headstock has a boring spindle of 130 - 160 mm with 800 mm (31.5 in) of W travel, driven through 2 ranges for 1,389 - 3,451 Nm at 3,000 - 4,000 rpm. The WD headstock is the Direct Drive bar, 120 - 160 mm, with 1,175 - 2,494 Nm at 4,000 - 5,000 rpm. The MD headstock drops the bar for a Direct Drive unit at 4,000 - 6,000 rpm and 66 - 90 kW.

There is a multitasking version as well. PAMA's TTR turning tables, Ø1,250 - Ø3,500 mm, take up to 32,000 kg and turn at up to 300 rpm, on the same hydrostatic principle as the milling tables.

Linear rapids are up to 50,000 mm/min. Pallet systems, attachment heads and automatic tool and head changers extend the machine, with Siemens, Heidenhain or Fanuc control.
