BOCHI CK7550 CNC LATHES

Technical Description

The QUICK TURN 450M is a mid-range CNC turning center engineered for high-precision production machining of complex rotational components. This machine features a maximum turning diameter of 29.48 inches with a swing clearance of 33.4 inches, accommodating large-diameter workpieces typical in aerospace and automotive manufacturing. The extended machining length of 78.6 inches enables efficient production of elongated shafts and cylindrical parts without repositioning. The bar capacity of 5.31 inches supports automated feeding of bar stock for continuous production runs, minimizing setup time and material waste. Equipped with an 18-inch chuck and CNC control system, this turning center delivers repeatable accuracy within ±0.0001 inches, meeting stringent industry tolerances. The machine incorporates a rigid construction with roller guides and an integral motor spindle to minimize vibration during high-speed machining, ensuring excellent surface finish and dimensional consistency. Advanced features include a high-speed drum turret with multiple tool positions, Y-axis capability for complex geometry machining, and optional C-axis indexing for precision contouring operations. The turning center integrates both turning and milling capabilities through its turret-mounted milling spindle, enabling multi-tasking machining to reduce cycle times and part handling. Its robust architecture supports heavy-duty cutting operations while maintaining high-speed feedrates, making it suitable for demanding applications in aerospace engine components, transmission systems, and precision industrial parts requiring tight tolerances and superior surface quality.
