WHY BUY USED DOOSAN S700
Purchasing a used Doosan S700 is a practical investment for manufacturers needing large-part machining capability at a lower cost. One of the main advantages is significant cost savings—used machines can deliver heavy-duty performance at a fraction of the price of new CNC lathes.
The S700 is built on a robust platform from Doosan Machine Tools, known for durability and long service life. Even machines with high cutting hours can continue to perform reliably when properly maintained, making them suitable for demanding production environments.
Another key benefit is capacity. With its large turning diameter and long bed length, the S700 allows machining of oversized shafts, pipes, and industrial components that smaller machines cannot handle. This expands a shop’s capabilities and job range.
Additionally, used machines are typically available for immediate delivery, reducing downtime compared to new machine lead times. Maintenance is also straightforward due to widely used CNC systems like Fanuc, with readily available spare parts and service support.
Overall, a used S700 offers strong performance, reliability, and excellent value for heavy turning applications.
HOW MUCH DOES A USED DOOSAN S700COST?
The cost of a used Doosan S700 varies based on year of manufacture, condition, configuration, and cutting hours. Machines built before 2000 are limited but typically range from $25,000 to $55,000. These units often have higher cutting hours and older CNC systems but can still handle heavy-duty operations effectively.
Machines from 2000 to 2010 are the most commonly available and generally fall within the $50,000 to $110,000 range. These machines typically include Fanuc controls, improved spindle performance, and moderate to high cutting hours (often 8,000–20,000+ hours), offering a strong balance between cost and capability.
For machines produced between 2010 and 2025, prices typically range from $110,000 to $220,000 or more, depending on condition, tooling, and upgrades. Machines with lower cutting hours (for example, under 5,000–8,000 hours) command premium pricing due to reduced wear and better overall condition.
Cutting time is one of the most important pricing factors—low-hour machines retain higher value, while high-hour machines are more affordable but may require maintenance such as spindle servicing, turret alignment, or guideway inspection to maintain optimal performance.
