MAG Giddings&Lewis offers horizontal boring mills to heavy-equipment manufacturers. The mills include the RT 1250 series of rotary-table types; the PT series of plain-table mills; the MC series, which includes automation features such as pallet shuttle and toolchangers; and the FT and FTR series of floor-type or traveling-column boring mills.
All mills are modular in design for quick delivery. Choices include various table styles and sizes, headstocks, controls, attachments and X-, Y- and W-axis travel options. The PT, RT and MC series offer three headstock choices that include a live spindle to allow for drilling and tapping as well as added reach for boring. The two- or four-speed headstocks have 130- or 155-mm diameter spindles with 3,500- to 4,000-rpm spindles.
Other options include programmable boring bars and contouring head systems. CH heads and NC-feedout bars reduce the number of setups, adding lathe capabilities such as turning, boring and grooving and allowing the machining of parts that might be too awkward to rotate on a lathe, the company says.
