MAG FTR 3500 horizontal borer
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 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 m W-axis reach to the spindle's existing 1 m extension. It provides maximum rigidity for full-power cuts by minimising spindle extension.
The ram's 400 by 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 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 m in half-metre increments. Travelling-column design allows virtually unlimited X-axis travel for processing of large and long workpieces or multiple batch parts, while 20 m/min 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. Available horsepower is 56 kW.
