The Mazak VARIAXIS i-300 AWC is a compact, high-performance simultaneous 5-axis vertical machining center designed specifically for automated production of small, complex components. What distinguishes this model is its integrated Auto Work Changer (AWC), which allows continuous unmanned operation by automatically loading and unloading workpieces from a stocker system. The machine can handle up to 32–40 workpieces in its storage system, making it ideal for high-mix, low-volume production environments.
The machine supports full 5-axis machining with a rigid trunnion-style table capable of indexing in extremely fine increments, ensuring high precision for complex geometries. It accommodates workpieces up to approximately 350 mm in diameter and 315 mm in height, with a maximum weight of around 65 kg. A standard 12,000 rpm spindle is available, with optional high-speed configurations up to 30,000 rpm and high-torque options for difficult materials.
The VARIAXIS i-300 AWC also features a large-capacity tool magazine system that can expand up to 500+ tools, enabling uninterrupted production across multiple part types. Combined with MAZATROL SmoothAi control and Smooth AWC software, the machine offers intelligent automation, reduced setup time, and consistent high-precision machining, making it a powerful solution for lights-out manufacturing.

WHY BUY USED MAZAK VARIAXIS I-300 AWC
Buying a used Mazak VARIAXIS i-300 AWC is a highly strategic move for manufacturers aiming to adopt automation without the significant capital investment required for a new system. One of the biggest advantages of this machine is its integrated automation capability—something that is typically very expensive to implement separately. Even in the used market, the AWC system provides substantial productivity gains through unattended machining and reduced operator dependency.
A critical factor when evaluating a used i-300 AWC is cutting time rather than just the manufacturing year. Machines used in continuous production environments, especially for small-part batch manufacturing, often accumulate high spindle hours due to the machine’s ability to run unattended for long periods. This can lead to wear in the spindle, tool changer, and automation components, which may require maintenance or refurbishment.
On the other hand, machines used in flexible job shop environments or prototype production tend to have lower cutting hours and better-preserved accuracy, making them more valuable despite being older. Another key advantage is that many used units come with high-capacity tool magazines and fully configured AWC systems, which significantly enhance production capability.
Overall, a used VARIAXIS i-300 AWC offers a rare combination of 5-axis precision and automation, making it an excellent investment for shops looking to scale production efficiently.
HOW MUCH DOES A USED MAZAK VARIAXIS I-300 AWCCOST?
The cost of a used Mazak VARIAXIS i-300 AWC depends on several factors, including year of manufacture, automation configuration, tool capacity, and most importantly, cutting hours. Since the i-300 AWC is a relatively modern machine introduced in the late 2010s, there are no units available before 2000, and even the 2000–2010 category does not apply directly. However, comparable early automated 5-axis systems may range between $120,000 and $250,000, typically with outdated controls and higher cutting hours.
For machines effectively in the 2010–2020 range (early availability of AWC-equipped systems), prices generally range from $250,000 to $400,000 depending on condition, number of pallets/work stockers, and spindle configuration. Machines with lower cutting hours and well-maintained automation systems command higher prices within this range.
For newer machines from 2020 to 2025, prices typically range from $400,000 to $800,000 or more, especially for units equipped with full AWC systems (32–40 stockers), large-capacity tool magazines, and high-speed spindle options. These machines are highly valued due to their ability to run unattended production cycles.
Cutting hours are the most critical pricing factor. Machines with low spindle hours and well-maintained automation systems command premium pricing, while heavily used machines are discounted due to potential refurbishment costs, particularly in the spindle, tool magazine, and AWC system components.
