lbs. can be processed on the MTV 1250 (up to 6,613 lbs. on the MTV 1000) within the machines’ X, Y and Z axes travels of 67 x 82 x 74 inches (MTV 1000) and 86 x 82 x 74 inches (MTV 1250), and both machines offer rapid traverse rates of 1,770 inches/min. Additionally, component diameters of up to 74 inches and 94 inches on the MTV 1000 and MTV 1250 can be ac- commodated.
High metal removal rates are guar- anteed with the all-geared A axis spin- dle drive, where the compact 1D-head with minimal distance between the spindle nose and A axis enables the use of very short tools and large bearings.
A specially coated damping disk in the 1D-head, combined with optimal
parameter settings from the Siemens 840D CNC, makes heavy roughing possible, semi-finishing and finishing in 5-axis operation.
Integrated high-pressure coolant permits efficient one-hit turning and the machines’ 30 HP angular automatic milling head enables easy access to internal surfaces and features. The angle head is loaded automatically from the tool magazine and tools can also be automatically changed into/out of the head.
The C axis CNC rotary table offers 500/400 rpm with torque ratings of 2,950/4,425 ft lbs. on the MTV 1000 and MTV 1250.
