The Doosan S310MLY is an advanced CNC turning center designed for high-precision and multi-tasking machining. Manufactured by Doosan Machine Tools, this model combines traditional turning with milling capabilities through live tooling and Y-axis functionality, making it ideal for complex parts production.
The S310MLY typically offers a maximum turning diameter of around 310 mm and a turning length up to 750 mm. It is equipped with a high-speed spindle capable of reaching up to 4,500 RPM and a spindle motor in the 15–22 HP range. The machine includes a 12-station turret and sub-spindle capability, allowing simultaneous machining and reduced cycle times.
A key feature of the S310MLY is its Y-axis capability, which enables off-center milling, drilling, and tapping operations. Combined with a sub-spindle, it allows complete machining of parts in a single setup, significantly improving productivity and accuracy.
Overall, the S310MLY is a versatile and efficient solution for shops requiring both turning and milling capabilities in one machine, especially for complex and high-precision components.

WHY BUY USED DOOSAN S310MLY
Buying a used Doosan S310MLY is a strategic investment for manufacturers looking to expand multi-tasking capabilities without the cost of a new machine. One of the biggest advantages is cost savings—used machines provide turning, milling, and sub-spindle functionality at a significantly lower investment compared to new multi-axis systems.
The S310MLY is built on a rigid and durable platform from Doosan Machine Tools, ensuring long-term reliability. Even machines with higher cutting hours can continue to perform efficiently when properly maintained, making them suitable for long production cycles.
Another key benefit is productivity. With live tooling, Y-axis, and sub-spindle capability, the machine can complete complex parts in a single setup. This reduces handling time, minimizes errors, and improves overall throughput—especially valuable in batch production and precision industries.
Additionally, used machines are typically available immediately, avoiding long lead times. Widely used CNC systems like Fanuc also make maintenance easier, with readily available spare parts and service support.
For businesses aiming to increase capability while controlling costs, a used S310MLY offers excellent value and flexibility.
HOW MUCH DOES A USED DOOSAN S310MLYCOST?
The cost of a used Doosan S310MLY depends on factors such as year of manufacture, condition, configuration, and cutting hours. Machines built before 2000 are rare for this model, but when available, they typically range from $15,000 to $35,000. These units usually have high cutting hours and older CNC systems.
Machines from 2000 to 2010 are the most common and generally fall within the $30,000 to $70,000 range. These machines often include Fanuc controls, live tooling, and moderate to high cutting hours (typically 8,000–20,000+ hours). They offer a strong balance between price and multi-tasking capability.
For machines produced between 2010 and 2025, prices usually range from $70,000 to $130,000 or more, depending on configuration, tooling, and condition. Machines with lower cutting hours (under 5,000–8,000 hours) command premium pricing, especially if equipped with sub-spindle and advanced live tooling.
Cutting time is a critical pricing factor—low-hour machines retain higher value, while high-hour machines are more affordable but may require maintenance, particularly in live tooling systems, spindle assemblies, and Y-axis components.
