KAC-4500B Heavy-Duty Profile Machining Center
The KAC-4500B/G is a high-performance, long-bed vertical machining center designed specifically for the heavy-duty processing of industrial steel profiles.
Advanced Product Features
Powerful BT50 Spindle System: The machine is equipped with a high-torque BT50 spindle (available in Belt or Direct drive) capable of speeds up to 6,000 rpm. This configuration supports larger diameter milling cutters and drills, making it effortless to machine hardened heavy steel.
High-Efficiency Feed & Loading: The X-axis utilizes a high-speed Rack and Pinion system reaching 40 m/min. Combined with a maximum table load of 1,000 kg/m², the machine handles heavy structural profiles with ease.
Automated Maintenance & Reliability: Every unit comes standard with an Automatic Grease Lubrication System and a Chain Plate Chip Conveyor. These features significantly reduce manual labor and maintenance costs while maintaining a clean, efficient production environment.
Integrated Tool Management: A 24-tool Disc Type magazine is included as standard, supporting complex, multi-process machining in a single cycle.
Primary Industry Applications
Structural Steel Construction: Precision milling and drilling for H-beams, I-beams, and large-scale architectural steel frameworks.
Transportation Infrastructure: Machining of long chassis components for trucks, trailers, and high-speed railway structural sections.
Energy Sector: Manufacturing of solar tracking rails, wind turbine structural parts, and large-scale power transmission components.
Heavy Machinery: Production of long boom arms and chassis frames for cranes and excavators.
Aerospace & Shipbuilding: Processing of extra-long aluminum or steel stringers and bulkheads.
