Mazak designed the Variaxis i-300 AWC for complex, high-mix part production in a compact, automation-ready platform. The vertical machining center is engineered for precision and flexibility. For example, it features a fully integrated automatic work changer CNC system t0 maximize machine utilization and minimize manual intervention. In addition, it can perform high-speed multi-surface CNC milling with complex surfaces and tight tolerances. These features make it an ideal manufacturing solution for aerospace, medical, and advanced job shop environments.
As a compact CNC machining center, the Variaxis i-300 AWC delivers powerful performance in a space-saving footprint. For example, its rotary/tilt table and high-speed spindle support simultaneous 5-axis operations to machine complex parts in one setup. Powered by Mazak’s SmoothX CNC control, the system delivers intuitive programming, rapid processing, and advanced motion control for consistent accuracy and repeatability. In addition, the integrated automatic work changer CNC function significantly boosts productivity with unattended, multi-job operation. This machining center also features intelligent scheduling, which can seamlessly handle a variety of workpieces across different materials. This capability makes it ideal for high-mix, low-volume environments, with the scalability needed for mid-volume manufacturing.
Mazak optimized the Variaxis i-300 AWC for high-speed multi-surface CNC milling across a broad range of part geometries. In addition, its compact design supports everything from prototyping to mid-volume manufacturing with reduced setup times, improved part consistency, and superior tolerance control. This 5-axis vertical machining center, is ideal for manufacturers aiming to modernize their operations with automation and precision-focused performance.

The Mazak Variaxis i-300 AWC combines simultaneous 5-axis machining with an automatic work changer for small, complex parts produced in changing quantities. Multiple work holders can be staged and scheduled so different part numbers move through the same cell with less manual intervention, making the platform relevant to high-mix production rather than only long runs of one component. A.W. Miller Technical Sales is an authorized Mazak distributor serving manufacturers throughout New York, Pennsylvania, Maryland, Delaware, Southern New Jersey, and Quebec, with applications engineering, installation, training, and factory-certified service.
Published capacity includes a 350 mm-diameter by 315 mm-high workpiece, a 65 kg maximum load, a 130 mm work-holder diameter, and a 32-position work stocker. The machine has 350 mm X-axis, 550 mm Y-axis, and 510 mm Z-axis travels, a 12,000 RPM BT40 spindle, and standard storage for 145 tools. The final configuration should be checked against the part, fixture, tooling, spindle demand, and automation plan.
Applications that use the Mazak Variaxis i-300 AWC work zone effectively include:
The 32-position work stocker stores work holders for scheduled exchange, allowing multiple jobs or repeat orders to be queued around available fixtures and tools.
Smooth AWC software manages work-holder and production information so a cell can organize different part numbers without treating every change as a manual machine setup.
The tilt-rotary work zone supports multi-face and contoured machining of small components while keeping the automated cell within a comparatively compact footprint.
Standard 145-tool storage gives the cell room for diverse processes, sister tools, and multiple part families; the actual tool matrix should be developed with expected job mix and tool life.
AWC means automatic work changer. The system stores and exchanges work holders so scheduled jobs can move into the machining area without an operator manually loading every fixture between cycles.
A.W. Miller publishes a 32-position work stocker and standard storage for 145 tools. The usable production mix depends on how many holders each job requires, tool commonality, sister-tool needs, inspection intervals, and the planned replenishment method.
The published maximum workpiece envelope is 350 mm in diameter by 315 mm high, with a 65 kg maximum load including the work holder. Fixture hardware, clamps, tool length, and rotary clearance must be included when confirming an application.
No. Its work stocker and large tool magazine can support high-mix, lower-volume production by staging different fixtures and part programs. It can also run repeat work, but the economic case depends on job frequency, setup content, cycle time, and unattended-production goals.
Work-holder location, part loading, program control, tool-life limits, broken-tool response, probing, chip control, coolant management, and exception handling must be defined. Reliable unattended operation comes from the complete process, not the work changer alone.
