The biggest feature is equipped with opposing main and auxiliary spindles,and the workpiece can be automatically transferred between the main and auxiliary spindles,achieving dual end machining.The milling spindle(B-axis)is integrated on the turret or independent,with Y-axis offset function,which can achieve milling and drilling off center line.The power cutting tool is driven by an independent servo motor with high torque.The machine tool adopts an integral bed and thermal symmetry design,with excellent thermal stability.A multi-channel high-end CNC system can simultaneously control multiple axis groups,achieving complex synchronous machining and interpolation movements.Equipped with online measuring probes and tool breakage detection function.
The main spindle and auxiliary spindle usually adopt a through-hole structure with a diameter of aboutΦ65 mm.The turning accuracy can reach IT6 level,and the surface roughness Ra is 0.8μm.The milling spindle power is about 5.5 kW.The B-axis positioning accuracy can reach±0.001°.The fast moving speed of each axis can reach 24-30 m/min.Knife towers are mostly servo driven,with short tool changing time.Control systems such as Fanuc 31i-B or Siemens 828D/840D.The machine tool has a complex structure with a net weight of approximately 8000 kg.
Specially designed for complex,high-precision,and multi-faceted machining parts,such as core components of automotive turbochargers,aerospace fasteners,high-precision valves,complex hydraulic joints,precision medical equipment,communication parts,etc.It is also increasingly popular in the processing of small precision parts such as clocks and jewelry.The concept of"one-time clamping,complete everything"greatly reduces the cumulative errors and production assistance time caused by multiple machine tools and multiple clamping,making it a key equipment for achieving intelligent manufacturing and lean production.
