According to machine tool builder Mag, a sidehead option for its vertical turning centers (VTCs) uses a 250-mm-square (10") ram to deliver 34,000-N (7,600-lbs) thrust from an optimized angle to efficiently turn tall or flanged parts in vertical orientation. The sidehead option is available on machines with table sizes ranging from 1,250 to 3,500 mm (49.2" to 137.7") that accommodate parts ranging to 3,700 mm (145.6") in diameter and 3,300 mm (129.9") in height. The sidehead provides a 1,250-mm (49.2") X-axis span and 1,900-mm (74.8") Z axis with a traverse rate of 20,000 mm/min. (787 ipm). It is equipped with a 40-tool chain magazine for automatic tool change and is available with modular Capto C8 or KM tool interface.
With tall, shaft-type parts mounted on the machine table and supported by a live center in the main ram, the approach angle of the sidehead minimizes bending forces on the part and machine components during maximum-thrust cuts to enable faster, more efficient and accurate metal removal. The sidehead also improves access for undercutting flanges or reaching features beneath them. It is suited for producing parts for the energy/power industry, heavy machinery, transportation and off-road equipment.
