USED MAZAK QUICK TURN NEXUS 400-II M – 2016

The 2016 MAZAK QUICK TURN NEXUS 400-II M is a heavy-duty CNC turning center designed for manufacturers requiring substantial turning capacity combined with live-tool machining capability, rigid construction, and efficient multi-operation production. Manufactured by Yamazaki Mazak, the QUICK TURN NEXUS 400-II M expands the standard QUICK TURN NEXUS 400-II platform by incorporating a live-tool turret, allowing manufacturers to perform turning, drilling, milling, tapping, and other secondary machining operations on the same machine. This multi-tasking capability can reduce workpiece transfers, improve positional accuracy between operations, and streamline production workflows.

The QUICK TURN NEXUS 400-II M utilizes a rigid slant-bed construction engineered to provide stable machining performance during demanding cutting operations. Its substantial machine structure helps control vibration and cutting deflection when machining large-diameter components or removing significant amounts of material. The machine is particularly well suited for industrial applications involving steel, stainless steel, cast iron, aluminum, alloy steels, and other engineering materials commonly found in heavy manufacturing environments.

The machine provides a maximum swing of approximately 33.27 inches and a maximum machining diameter of approximately 23 inches. Depending on the bed-length configuration, maximum machining length can reach approximately 40.4 inches on the shorter configuration, with longer-bed versions available for substantially longer components. The 400-II M platform is therefore capable of handling a broad range of medium and large cylindrical components while providing the rigidity needed for demanding production machining.

One of the major advantages of the QUICK TURN NEXUS 400-II M is its powerful main spindle.

The QUICK TURN NEXUS 400-II M incorporates a 12-station turret designed to support both conventional turning tools and powered rotary tooling. The live-tooling system can provide approximately 4,000 RPM rotary tool speed, with approximately 10 HP and 8 kW output listed for the rotary tooling spindle. This enables the machine to perform cross-drilling, end drilling, tapping, milling, slotting, and other secondary operations without requiring the workpiece to be moved to another machining center.

The X-axis provides approximately 12.13 inches of travel, while the Z-axis provides approximately 42.13 inches on the 40-inch bed configuration. Longer-bed versions of the machine can provide approximately 83.5 or 124.75 inches of Z-axis travel depending on the selected configuration. This makes it important to verify the individual bed length when evaluating a used QUICK TURN NEXUS 400-II M because work envelope specifications vary significantly between machine configurations.

The machine’s live tooling capability is particularly valuable for manufacturers producing complex components that require turning and secondary milling operations. Instead of transferring the workpiece between a lathe and machining center, operators can complete multiple operations within a single setup. This can reduce setup time and improve the relationship between turned and milled features.

The QUICK TURN NEXUS 400-II M can machine a wide range of materials including carbon steel, stainless steel, alloy steel, cast iron, aluminum, brass, bronze, and engineering plastics. Appropriate tooling, cutting parameters, coolant delivery, and workholding are required depending on the specific material and production application.

WHY CHOOSE MAZAK QUICK TURN NEXUS 400-II M

The MAZAK QUICK TURN NEXUS 400-II M is designed for manufacturers requiring substantial CNC turning capability combined with live-tool machining flexibility. Its large maximum swing, approximately 23-inch maximum machining diameter, 12-inch chuck, and powerful spindle provide a substantial platform for machining medium and large industrial components.

One of the machine’s most important advantages is the live-tool turret. Traditional CNC turning centers require a second machine for operations such as cross-drilling, tapping, slotting, and milling. The QTN 400-II M can perform many of these secondary operations directly on the turning center, reducing workpiece transfers and improving production efficiency.

The 12-station turret provides space for a useful combination of conventional turning tools and powered tooling. Published specifications identify approximately 4,000 RPM rotary-tool speed and approximately 10 HP output for the live-tool system, giving the machine useful secondary machining capability.

Another major advantage is the machine’s spindle capacity. With approximately 2,500 RPM maximum spindle speed and substantial motor output, the machine is optimized for applications requiring strong cutting performance and material removal. This makes it particularly useful for steel, stainless steel, cast iron, and other industrial materials.

The approximately 4-inch bar-work capacity also gives manufacturers flexibility when machining components directly from bar stock. This can be particularly useful for shafts, sleeves, fittings, bushings, and other cylindrical production components.

The machine’s rigid slant-bed design contributes to machining stability during demanding turning operations. Structural rigidity becomes increasingly important when machining large-diameter components because cutting forces can increase significantly compared with smaller turning applications.

Another advantage is the variety of available bed lengths. The QUICK TURN NEXUS 400-II M platform was offered with multiple bed-length configurations, allowing manufacturers to select a machine according to the required component length. Buyers of used equipment should verify the exact bed length because it directly affects Z-axis travel, machine footprint, and maximum machining length.

The machine’s combination of a 12-inch chuck, approximately 33.27-inch maximum swing, approximately 23-inch maximum machining diameter, and powerful spindle makes it particularly attractive for shops that routinely handle larger cylindrical components.

One of the biggest advantages of buying used CNC equipment is the opportunity to increase manufacturing capacity without committing the full cost of new equipment. A properly maintained QTN 400-II M can continue providing productive machining capability for many years when its spindle, guideways, ballscrews, turret, control, coolant system, and other major components are maintained correctly.

The live-tool capability is another important reason manufacturers may consider a used QTN 400-II M. Instead of purchasing a separate machining center for secondary operations, manufacturers can complete many milling, drilling, tapping, and slotting operations directly on the turning center.

This can reduce workpiece handling and improve consistency between turning and secondary features. For complex components, keeping the workpiece in one setup can be particularly useful.

Used machines may also be available with valuable accessories already installed. Depending on the individual machine, buyers may find chip conveyors, bar feeders, hydraulic workholding, live-tool holders, parts catchers, tooling packages, coolant systems, and other production equipment included with the purchase.

These accessories can represent significant additional value because purchasing and installing them separately can increase the total cost of putting a machine into production.

Another benefit is potentially faster availability compared with ordering new equipment. Manufacturers that need additional turning capacity may be able to purchase an available used machine and begin the installation process much sooner than waiting for a new-machine production schedule.

Mazak equipment is also widely recognized throughout the machining industry, meaning many shops already have operators, programmers, and maintenance personnel familiar with Mazak CNC systems.

Before purchasing a used QTN 400-II M, buyers should carefully inspect spindle condition, chuck operation, turret indexing, live-tool operation, X- and Z-axis movement, ballscrews, guideways, hydraulic systems, lubrication, coolant delivery, electrical systems, and CNC control operation.

Spindle hours and machine operating hours should be reviewed whenever available. Maintenance documentation can also help buyers understand previous service intervals and identify major components that may have been replaced.

The live-tool system deserves particular attention because rotary-tool performance can affect the machine’s overall multi-tasking capability. Buyers should verify live-tool spindle operation, tooling interfaces, indexing accuracy, and any unusual noise or vibration.

The exact bed length should also be confirmed. The QTN 400-II M was available in multiple configurations, and a longer-bed machine will have a substantially different footprint and machining envelope than a shorter-bed model.

For manufacturers seeking a large CNC turning center with live-tool capability and substantial spindle power, a used 2016 MAZAK QUICK TURN NEXUS 400-II M can provide significant production flexibility while avoiding the full acquisition cost of a new machine.

HOW MUCH DOES A USED MAZAK QUICK TURN NEXUS 400-II M COST?

The price of a used 2016 MAZAK QUICK TURN NEXUS 400-II M depends on machine condition, spindle hours, bed length, control configuration, live-tooling condition, installed options, chuck condition, tooling packages, maintenance history, geographic location, and current used CNC machinery market conditions.

A typical used 2016 MAZAK QUICK TURN NEXUS 400-II M may be offered in the approximate $70,000 to $135,000 range depending on machine configuration, condition, installed accessories, and seller. Machines with low operating hours, strong maintenance records, desirable automation equipment, and production-ready tooling may be priced above this range.

Machine condition remains one of the most important factors when determining the value of a used QTN 400-II M. Buyers should inspect the main spindle, chuck, turret, live-tool system, axis movement, ballscrews, guideways, hydraulic system, lubrication system, coolant system, and CNC control.

The spindle deserves particular attention because the machine is designed for substantial cutting performance. Buyers should inspect spindle noise, vibration, temperature behavior, taper or chuck condition, runout, and overall performance under load.

The live-tool system can also influence value significantly. A machine with a fully operational live-tool turret and a good selection of rotary holders may provide considerably more production capability than a machine requiring extensive tooling replacement.

Bed length is another major pricing consideration. The QTN 400-II M platform was offered with multiple bed configurations, including approximately 40-, 80-, and 120-inch versions. Longer-bed machines provide significantly more Z-axis capability but also require additional floor space and transportation considerations.

Installed accessories can also affect pricing. Bar feeders, chip conveyors, parts catchers, probing systems, tooling packages, high-pressure coolant, and additional live-tool holders may increase the overall value of a used machine.

Transportation should also be included when calculating the total acquisition cost. Large QTN 400-II M configurations can be substantial machines, and professional rigging, loading, transportation, unloading, leveling, and installation may represent a significant additional expense.

Buyers should also consider tooling and workholding. A machine purchased without adequate live-tool holders, boring bars, turning holders, chucks, or production tooling may require additional investment before it can begin normal production.

Dealer-supplied machines can sometimes command higher asking prices than privately sold equipment because the transaction may include inspection, installation assistance, financing, warranty coverage, or technical support.

The 2016 model year means buyers should place particular emphasis on actual machine condition rather than relying only on the year of manufacture.
