Five axis horizontal machining centre
- December 2, 2018
Makino has introduced a five axis horizontal machining centre, the a500Z.
The new machine builds on Makino’s nx-series 4-axis HMC. It adds a factory-built and fully-integrated “Z-type” fifth axis to accommodate today’s more complex part geometry challenges in a minimum number of work-holding setups and machining operations. The unique kinematic arrangement of the a500Z minimizes the force path lengths through the spindle and through the workpiece. This transfers both cutting loads and reactive forces into the machine’s three-point leveled bed, maximizing metal removal rates and perishable tool life due to enhanced system rigidity.
All axes on the a500Z have closed loop active temperature control standard. This provides not only superior dimensional control but also extended component life even in demanding production environments. With rapid rates for all linear axes of 2,362 inches per minute (60 metres per minute) and a B-axis rotation rapid rate of 45,000 degrees per minute, the a500Z enables more efficient machine movements.
The a500Z’s standard 14,000 RPM high-power spindle offers output capabilities of 49.6 HP (37 kW) peak power and 223 ft-lbs (303 N-m) peak torque, making it ideal for wide-ranging material applications. Tool changer magazine sizes range from the standard 60 tool capacity ring to a 313 matrix magazine.
The standard automatic pallet changer on the a500Z increases machine utilization, allowing work-holding fixture tending on one pallet while the other pallet’s workpiece is being machined.
