GF Mikron MILL S 600 U

The Mikron MILL S 600 U is a pallet-fed 5-axis high-speed mill with 800 mm of X, 600 mm of Y and 500 mm of Z, a 120 kg table load and 61 m/min linear rapids. It belongs to GF Machining Solutions' MILL S/X U series, where GF names aerospace, medical and mold making as the target work, and it is the standard-dynamics counterpart of the Mikron MILL X 600 U, which is listed at 100 m/min on an otherwise identical table.

Most buyers will weigh it against the Mikron MILL E 700 U, which has a similar 700 × 600 × 500 mm envelope. The two take opposite routes. The Mikron MILL E 700 U carries 450 kg on a T-slot table Ø630 mm with spindles up to 20,000 rpm. The S 600 U carries 120 kg on pallet surfaces only, Dynafix 280 x 280/350 x 350, GPS 240 x 240 or UPC 320 x 320, and spins far faster. Heavy steel blocks point to the E; small, accurate parts run in batches from pallets point to the S.

Three spindles are listed. The 24,000 rpm HSK-A63 unit is rated 30 kW; a 36,000 rpm HSK-E50 and a 42,000 rpm HSK-E40, the latter with 8.8 Nm, cover smaller tools. Magazine sizes follow the interface and run up to 220 pockets on HSK-A63 and HSK-E50, and to 168 on HSK-E40.

The swivel axis travels +30° / -110° and rotary n x 360°, at 60 / 150 rpm. Control is Heidenhain TNC 7 or Siemens SINUMERIK ONE with GF's Smart Machine modules. The machine weighs 9,900 kg.
