The Doosan S310SML is an advanced multi-tasking CNC turning center designed for high-precision and complex part machining. Built by Doosan Machine Tools, this model combines turning, milling, and sub-spindle operations into a single platform, significantly improving productivity and reducing setup time.
The S310SML typically offers a maximum turning diameter of around 310–350 mm and a turning length of up to 750 mm. It is equipped with a high-speed spindle capable of reaching approximately 4,500 RPM and a spindle motor around 15 kW, delivering consistent cutting performance across various materials.
A key feature of the S310SML is its sub-spindle and live tooling capability, along with full C-axis control, allowing simultaneous machining on both sides of the part. This enables complete machining in a single setup, reducing handling time and improving accuracy. The machine also includes a 12-station turret and is commonly fitted with reliable CNC controls such as Fanuc.
Overall, the S310SML is a powerful and versatile turn-mill solution, ideal for manufacturers producing complex components with tight tolerances.

WHY BUY USED DOOSAN S310SML
Purchasing a used Doosan S310SML is an excellent investment for manufacturers seeking multi-tasking machining capabilities at a reduced cost. One of the biggest advantages is cost efficiency—used machines offer turning, milling, and sub-spindle functionality at a fraction of the cost of new multi-axis machines.
The S310SML is built on a rigid and durable platform from Doosan Machine Tools, ensuring long-term reliability even under demanding production conditions. Many machines remain highly productive even after years of operation, especially when properly maintained.
Another major benefit is productivity. With dual spindles, live tooling, and C-axis capability, the machine can complete complex parts in a single setup. This reduces cycle time, minimizes manual handling, and improves overall efficiency—especially valuable for batch production and precision industries.
Additionally, used machines are typically available immediately, eliminating long lead times. Maintenance is also straightforward due to widely used control systems like Fanuc, with easily accessible spare parts and service support.
Overall, a used S310SML provides a strong balance of capability, efficiency, and value for modern machining needs.
HOW MUCH DOES A USED DOOSAN S310SMLCOST?
The cost of a used Doosan S310SML 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 generally have high cutting hours and older CNC systems.
Machines from 2000 to 2010 are the most common in the market and typically range from $30,000 to $70,000. These machines usually include live tooling, sub-spindle capability, and moderate to high cutting hours (often 8,000–20,000+ hours), offering a strong balance between price and functionality.
For machines produced between 2010 and 2025, prices generally range from $70,000 to $140,000 or more, depending on configuration, tooling, and condition. Machines with lower cutting hours (under 5,000–8,000 hours) command higher prices, especially those with well-maintained sub-spindle and live tooling systems.
Cutting time is a critical factor—low-hour machines retain premium value, while high-hour machines are more affordable but may require maintenance, particularly in spindle assemblies, live tooling units, and synchronization systems between the main and sub-spindle.
