USED MAZAK SLANT TURN 550

The Mazak Slant Turn 550 is a heavy-duty CNC turning center designed for large-capacity machining of oversized components requiring high torque, long-bed flexibility, and stable cutting performance. It is part of Mazak’s Slant Turn 500/550/600 series and is widely used in oil & gas, power generation, shipbuilding, railways, and heavy engineering industries where large shafts, pipes, and forged components must be machined under continuous heavy loads.

The machine is built on a rigid slant-bed structure that enhances chip evacuation and improves stability during aggressive roughing operations. It typically features a 21-inch chuck and supports a maximum swing of approximately 1040 mm, with a maximum machining diameter of around 910 mm, making it suitable for very large industrial workpieces.

Depending on configuration, the Slant Turn 550 offers multiple bed lengths, with machining lengths ranging from approximately 1016 mm up to over 4000 mm, allowing flexibility for both medium and extra-long shaft machining applications.

The spindle system is designed for high torque output rather than high-speed machining, typically delivering around 45 kW (60 HP) power in many configurations, making it ideal for heavy roughing and continuous material removal in tough materials like alloy steel and forgings.

The machine is equipped with a 12-station heavy-duty turret, designed for rigid tool holding and stable indexing under load. Depending on configuration, it may include milling capability (M version), enabling drilling, tapping, and light milling operations directly on the lathe. This improves productivity by reducing secondary setups while maintaining a strong focus on rigidity and durability.

Control systems typically include Mazatrol Matrix or Mazatrol Smooth series depending on machine generation, offering conversational programming, simulation, and efficient setup tools for complex part machining.

Overall, the Mazak Slant Turn 550 is a true heavy-industrial CNC lathe designed for maximum rigidity, torque, and reliable performance in demanding large-part production environments.

WHY BUY USED MAZAK SLANT TURN 550

Buying a used Mazak Slant Turn 550 is a strong investment for manufacturers who require a large-capacity, high-torque CNC lathe at a significantly reduced capital cost. This machine is built for extreme-duty machining, making it highly valuable in industries such as oil & gas, power plants, and heavy fabrication where large shafts, pipes, and structural components are produced in continuous cycles.

A key evaluation factor is cutting hours. Machines with low usage (under 5,000–10,000 hours) generally maintain excellent spindle torque, stable machining accuracy, and strong structural integrity. These are ideal for high-precision production environments. Mid-hour machines (10,000–25,000 hours) are commonly found in industrial use and can still perform reliably if properly maintained. High-hour machines (25,000+ hours) may require inspection of spindle bearings, gearbox wear, turret alignment, and guideway condition, but can still be used effectively for rough machining or less critical applications.

A major advantage of buying used is cost efficiency. Since most depreciation occurs early in the machine’s lifecycle, buyers can access Mazak’s heavy-duty turning capability at a fraction of the original price. This significantly improves ROI for companies machining large and heavy components.

Mazak machines also benefit from strong global service support and widely used Mazatrol controls, which simplify programming and reduce operator training time. Even older Slant Turn 550 machines remain highly respected due to their rigid construction and long service life.

Additionally, many used machines include valuable accessories such as tailstocks, steady rests, large hydraulic chucks, and chip conveyors, improving productivity without additional investment.

Overall, the Slant Turn 550 remains a strong used CNC option due to its durability, extreme torque capability, and ability to handle some of the most demanding large-part machining applications in heavy industry.

HOW MUCH DOES A USED MAZAK SLANT TURN 550 COST?

The price of a used Mazak Slant Turn 550 depends on manufacturing year, machine condition, cutting hours, bed length, spindle condition, and installed options such as milling capability, tailstock, steady rests, or automation systems. As a large-capacity heavy-duty CNC lathe, it is widely used in demanding industrial environments.

For newer machines (approximately 2010–2020 or well-maintained units), prices typically range from $95,000 to $180,000. These machines generally have lower cutting hours, strong spindle performance, and Mazatrol Matrix or Smooth controls. Fully equipped machines with long bed lengths (up to 4000 mm class) and full accessory packages tend to be at the upper end of this range.

For mid-generation machines (around 2000–2010), typical prices fall between $50,000 and $110,000. These machines generally have moderate cutting hours (10,000–25,000 hours) and remain widely used in production environments. They are reliable but require careful inspection of spindle wear, gearbox condition, turret accuracy, and axis alignment before purchase.

Older machines (pre-2000 models) are generally priced between $25,000 and $60,000 depending on condition and usage history. These units often exceed 25,000–40,000 cutting hours and may require maintenance such as spindle rebuilding, control upgrades, or ball screw replacement. However, they can still be useful for rough machining or lower-precision heavy work.

Cutting hours are a key pricing factor because they directly affect spindle life, machining accuracy, and long-term stability. Lower-hour machines provide better precision and faster cycle performance, while higher-hour machines are more affordable but may require increased maintenance and show reduced accuracy under continuous heavy-load operations.

Overall, the Slant Turn 550 holds strong resale value due to its heavy-duty construction, large machining capacity, and proven reliability in high-load industrial production environments.
