New Floor-type Boring Mill from MAG


MAG’s new FTR 3500 floor-type horizontal boring mill (HBM) is a versatile, mid-sized job-shop machine, capable of a full 2 m reach inside parts with a ram-supported spindle. The workhorse machine tool is ideal for “heavy metal” milling, as well as precision multi-axis contouring, boring, drilling, and tapping on large parts for the construction, oil field, and wind energy industries.

The machine’s collinear ram, made from ductile iron, adds a 1-meter W-axis reach to the spindle’s existing 1-meter extension. It provides maximum rigidity for full-power cuts by minimizing spindle extension. The ram’s 400 x 500 mm cross section is ideally sized for extended reach with rigid support to enable the machine to perform additional operations, helping to reduce time-consuming large-part setups for faster cycle times and less work-in-process. The machine’s ram displacement compensation system uses a hydraulically actuated tension rod system to counteract the static loads of attachments, and control ram displacement caused by variations in ram extension and attachment weight. Like all MAG boring mills, the FTR 3500 includes W and Z-axis thermal compensation software to dynamically offset spindle growth.

The FTR 3500 is available in column heights of 2 to 5 meters (6.6 to 16.4 ft) in half-meter increments. Traveling-column design allows virtually unlimited X-axis travel for processing of large and long workpieces or multiple batch parts, while 20 m/min (787 ipm) rapid traverse rates reduce cycle times. The choice of spindle power trains includes two four-speed versions available with spindle diameters of 130 and 155 mm (5 and 6 in). Available horsepower is 56 kW (75hp). Modular design allows economical customization of the FTR 3500, along with industry’s fastest machine build and delivery. The machine can be fitted with choice of travels, headstocks, spindle diameters and spindle power, controls, coolant systems, workholding and tool magazines. Front-end options include a range of indexing and rotary tables, auxiliary slides and floor plates. An optional attachment rack enables storage and quick change of contouring heads, programmable boring bars, right angle heads and more to speed production. Optional cartridge-style ram allows for a fixed attachment or attachment changing operations.
