WHY BUY USED DOOSAN S670L

Purchasing a used Doosan S670L is a smart investment for manufacturers needing large-part turning capability at a lower cost. One of the biggest advantages is significant cost savings—these machines were originally priced between $200,000 and $300,000 when new, making used units highly attractive from a value perspective.

The S670L is built with a heavy-duty structure and high-quality components from Doosan Machine Tools, ensuring long service life. Even machines with higher cutting hours can continue to perform reliably with proper maintenance, making them suitable for long production cycles.

Another key benefit is capacity. With its large turning diameter and extended bed length, the machine allows shops to handle bigger and longer components that smaller lathes cannot accommodate. This expands production capability and job opportunities.

Used machines are typically available immediately, reducing downtime compared to new machine lead times. Additionally, widely used CNC systems like Fanuc ensure easy maintenance, with readily available spare parts and service support.

Overall, a used S670L provides a strong combination of performance, capacity, and cost efficiency.

HOW MUCH DOES A USED DOOSAN S670L COST?

The cost of a used Doosan S670L depends on year of manufacture, condition, configuration, and cutting hours. Machines manufactured before 2000 are relatively uncommon, but when available, they typically range from $25,000 to $55,000. These machines often have higher cutting hours and older CNC systems but can still perform heavy-duty operations effectively.

Machines built between 2000 and 2010 are the most commonly available and generally range from $50,000 to $110,000. These units usually feature Fanuc controls, improved spindle performance, and moderate to high cutting hours (often 8,000–20,000+ hours). They offer a strong balance between cost and capability for most machining applications.

For machines produced between 2010 and 2025, prices typically range from $110,000 to $200,000 or more, depending on condition, tooling, and upgrades. Machines with lower cutting hours (under 5,000–8,000 hours) command premium prices due to reduced wear and better overall condition.

Cutting time is a critical factor in valuation—low-hour machines retain higher value, while high-hour machines are more affordable but may require maintenance such as spindle servicing, turret alignment, or ball screw replacement to maintain optimal performance.
