Pioneers in Machining Technology
Availability in the UK and Ireland of a large, portal, 5-axis machining centre, built by the Italian company Mecof, is announced by sole agent NCMT. Called UMILL 1800, the versatile machine has a 1,800 mm x 2,150 mm x 1,250 mm working volume and does not require special foundations. It is suitable for 5-axis and 5-sided metalcutting applications in industries as diverse as aerospace, oil and gas, power generation and automotive.
The machine can be supplied with either an HSK 100-A/T, 58 kW, 12,000 rpm spindle delivering up to 372 Nm of torque, an HSK 63-A, 63 kW, 20,000 rpm, 125 Nm alternative, or an ISO 50, 48 kW, 6,000 rpm, 750 Nm mechanical spindle. A-axis head positioning is in a plane at an angle to the table, allowing deployment of the spindle from horizontal to vertical as well as undercutting at up to 15 degrees.
There is a choice of two torque motor-driven rotary tables for accepting workpieces weighing up to 10 tonnes. The 1,700 mm x 1,400 mm milling table has a 10 rpm drive with a maximum torque of 6,000 Nm, while a 1,800 mm diameter mill-turn table offers 250 rpm and 4,000 Nm.
Despite its large size, the machine is highly productive with up to 60 m/min feed rate in the linear axes. The tool magazine can have 80, 120 or 200 pockets. Control is by either the Heidenhain 640HSCI or Siemens 840D sl.
