Kitamura Machinery’s compact MedCenter5AX vertical machining center is designed for high-precision, accurate and fast machining of complex, multi-sided parts in one setup. The machine employs an X, Y and Z axis, a tilting A axis (±120 degrees) and a rotary C axis (360 degrees) with 0.001-degree minimum indexing control. Machining complicated parts like orthopedic implants or aerospace parts can be completed in one operation, according to the company, reducing overall machining time. Maximum workpiece size is 220 mm in diameter by 175 mm in hight (8.7" × 6.9"), with a maximum table load capacity of 20 kg (44 lbs). The direct-driven fourth- and fifth-axis rotary tables provide smooth simultaneous five-axis movement.
Kitamura’s 30,000-rpm, 24.5-hp, direct-drive HSK-E40 spindle offers rigidity and stiffness while allowing for superfine finish capabilities. Ideal for small-diameter tools and hard milling, the MedCenter5AX offers a standard air-through-spindle feature for dry cutting and is also equipped to handle up to 1,000-psi through-spindle coolant for deep-hole drilling requirements.
The MedCenter5AX may be compact, but it is equipped with a large 40-tool magazine capable of changing tools in 1.5 sec., according to the company.
The machine uses Kitamura’s Arumatik-Mi control, which is said to feature intuitive touchscreen technology as well as dedicated five-axis functions and advanced NC simulation and verification software.
This Atlanta shop succeeded at becoming an aircraft-industry parts supplier. The lessons of its success have a lot to do with commitment and enthusiasm.
Different machines offer different approaches to rotary travel, and each design has its own strengths. Here's how they compare.
Another type of tool engages comparatively more of the work to facilitate larger stepovers for improved efficiency and surface finish in five-axis finishing operations.
