USED MAZAK QUICK TURN NEXUS 350

The MAZAK QUICK TURN NEXUS 350 is a heavy-duty CNC turning center designed for manufacturers that need substantial turning capacity, high spindle power, large bar capacity, and the rigidity required for machining medium- to large-sized cylindrical components. The QUICK TURN NEXUS 350 platform was developed as part of Mazak’s QUICK TURN NEXUS family, combining a rigid CNC turning structure with the MAZATROL NEXUS control system and multiple bed-length options. Depending on the specific configuration, the machine can be equipped for relatively short components or long workpieces requiring machining lengths approaching 80 inches.

The standard QUICK TURN NEXUS 350 is built primarily for two-axis CNC turning, with X- and Z-axis movement controlling the cutting tool relative to the rotating workpiece. The machine provides a maximum swing of approximately 26.77 inches, while maximum machining diameter is approximately 16.54 inches on the standard 350 configuration. Maximum machining length depends on bed length, with published specifications showing approximately 23.8 inches for the 26-inch bed, 60.72 inches for the 60-inch bed, and 80.92 inches for the 80-inch bed. This range allows manufacturers to select a configuration appropriate for the size and length of their components.

One of the major strengths of the QUICK TURN NEXUS 350 is its spindle system. The standard platform provides a 4-inch maximum bar work capacity, making it appropriate for substantially larger bar stock than many compact CNC turning centers. Published specifications for the 350-II show a maximum spindle speed of approximately 3,300 RPM, a spindle bore of approximately 4.41 inches, and a main spindle motor rated around 40/30 HP. This combination gives the machine the power and torque required for aggressive turning operations on steel, stainless steel, cast iron, aluminum, and other engineering materials.

The machine’s large work envelope makes it particularly suitable for manufacturers producing shafts, sleeves, flanges, housings, hubs, bushings, rollers, hydraulic components, and other cylindrical parts. A long-bed configuration can accommodate components with machining lengths of approximately 60 inches or more, while shorter-bed versions are better suited to large-diameter parts where length is less critical. The ability to choose among different bed lengths is one of the useful characteristics of the QUICK TURN NEXUS 350 family.

The 12-station turret provides the tool capacity needed for multi-operation turning. A typical setup can include roughing tools, finishing tools, boring bars, threading tools, grooving tools, cutoff tools, and other application-specific tooling. The turret can therefore support multiple operations within a single setup, helping manufacturers maintain consistent workholding and reduce manual intervention between machining processes. Documented QTN 350-II machines use a 12-position drum-type turret.

The QUICK TURN NEXUS 350 is also available in configurations that add milling and other multi-axis capabilities. The 350M, 350MY, and 350MSY variants add different combinations of driven tooling, Y-axis, and sub-spindle functionality. The standard QUICK TURN NEXUS 350 should therefore be distinguished from the M, MY, and MSY versions when evaluating a used machine. The 350M, for example, adds milling capability, while the MSY configuration combines milling, Y-axis capability, and a second spindle.

The MAZATROL NEXUS control is another defining characteristic of the machine family. Documented QUICK TURN NEXUS 350-II machines use the MAZATROL NEXUS Matrix control, while other machines in the broader Nexus family may use different generations of Mazak control depending on production year and configuration. The control provides conversational programming capabilities as well as conventional CNC programming functionality, giving shops flexibility when programming repeat production work and more complex components.

For manufacturers that require a robust CNC lathe for larger components, the MAZAK QUICK TURN NEXUS 350 provides a combination of large swing, substantial bar capacity, high spindle power, multiple bed lengths, a 12-station turret, tailstock support, and Mazak CNC control technology. Its configuration options make it suitable for job shops, production manufacturers, industrial equipment producers, automotive suppliers, oilfield component manufacturers, hydraulic equipment companies, and other businesses machining medium- to large-sized cylindrical parts.

INDUSTRIES THAT USE MAZAK QUICK TURN NEXUS 350

The oil and gas industry is an important application for large-capacity CNC turning centers. Components used in oilfield equipment can involve large diameters, substantial bar stock and long cylindrical geometries. The QUICK TURN NEXUS 350’s 4-inch bar capacity and long-bed options can be useful for shafts, sleeves, connections, valve components and other oilfield-related parts.

The automotive industry can use the machine for medium- and large-sized production components. Shafts, hubs, bushings, brake-related components, drivetrain parts and other cylindrical components can be produced when their dimensions fall within the selected machine configuration.

The heavy equipment industry is another natural application. Construction, mining, agricultural and industrial equipment frequently require large pins, shafts, bushings, hubs and sleeves. The combination of substantial spindle power and tailstock support makes the machine suitable for components where rigidity and workholding are important.

The industrial machinery industry can use the QUICK TURN NEXUS 350 for manufacturing shafts, rollers, couplings, housings, sleeves and other rotating components. The multiple bed-length options allow manufacturers to select a configuration based on component length.

The hydraulic and pneumatic equipment industry can use the machine for cylinders, sleeves, valve components, fittings, adapters and other precision cylindrical parts. The large bar capacity is useful when components require substantial stock diameters.

The power generation industry can use large CNC turning equipment for selected shafts, sleeves, couplings, rings and other rotating components. Long-bed configurations are particularly relevant when components have substantial overall lengths.

The general job shop and contract manufacturing industry can benefit from the machine’s flexibility. A shop can use the QUICK TURN NEXUS 350 for different part families rather than dedicating the machine to only one component. The 12-station turret allows tooling to be changed between jobs while maintaining CNC control over the machining process.

The aerospace and defense industries can also use this class of CNC turning center for selected larger cylindrical components. Although many aerospace components require specialized multi-axis machining, large shafts, housings, sleeves, rings and other turned components can be produced on a properly configured QUICK TURN NEXUS 350.

WHY CHOOSE MAZAK QUICK TURN NEXUS 350

One of the primary reasons to choose the MAZAK QUICK TURN NEXUS 350 is its combination of work envelope and spindle capacity. With approximately 26.77 inches of swing and approximately 16.54 inches of maximum machining diameter on the standard 350 configuration, the machine can accommodate components larger than those typically handled by compact CNC lathes.

The 4-inch bar capacity is another major advantage. Manufacturers working with larger bar stock can load substantially more material through the spindle than would be possible on a smaller CNC lathe. This makes the machine particularly useful for shaft, sleeve, bushing and other large cylindrical components.

The 40/30 HP spindle provides the power required for aggressive turning operations. Heavy roughing of steel and other difficult materials can generate substantial cutting loads, and the machine’s large spindle and rigid structure are designed for this type of work.

The different bed-length configurations make the platform flexible. A 26-inch bed can be used for shorter components, while 60- and 80-inch versions provide much greater capacity for long shafts and other extended workpieces.

The 12-station turret provides sufficient tooling flexibility for most conventional turning applications. Roughing, finishing, boring, threading, grooving and cutoff operations can all be incorporated into the same CNC setup.

The tailstock is especially useful when machining long components. Supporting the free end of a shaft or similar workpiece can help reduce deflection and improve machining stability.

The MAZATROL NEXUS control is another reason manufacturers choose the platform. Conversational programming can simplify setup for certain applications, while EIA/ISO programming allows programs generated through conventional CNC workflows or CAM systems to be used.

Finally, the QUICK TURN NEXUS 350 provides a proven platform for shops that need a dedicated large-capacity CNC lathe. Its combination of spindle power, bar capacity, work envelope, turret capacity and long-bed options makes it adaptable to many production environments.

WHY BUY USED MAZAK QUICK TURN NEXUS 350

Buying a used MAZAK QUICK TURN NEXUS 350 can provide manufacturers with access to substantial CNC turning capacity without the capital requirement of a new large-capacity turning center.

One of the main benefits is the machine’s physical machining capability. Features such as the large spindle bore, 4-inch bar capacity, 40/30 HP spindle and large swing remain valuable regardless of whether the machine is new or used.

A used machine may also already include production equipment such as a hydraulic chuck, tailstock, chip conveyor, tool presetting system and tooling. A documented QTN 350-II machine, for example, includes a 15-inch hydraulic chuck, 12-position turret, tailstock, chip conveyor, ToolEye and toolholders.

The machine can be particularly attractive to job shops expanding into larger work. A shop that already has several smaller CNC lathes can add a QTN 350 to handle larger components without replacing its existing equipment.

The multiple bed-length configurations also make it possible to find a used machine that is appropriate for a specific production requirement. Buyers can compare shorter-bed and long-bed machines according to the length of the parts they expect to produce.

The Mazak control system can be another advantage for shops already familiar with Mazatrol programming. Operators who have experience with Mazak equipment may require less training than they would when moving to a completely different CNC platform.

However, used buyers should inspect the machine carefully. Spindle condition, chuck condition, turret indexing, ballscrews, guideways, tailstock operation, hydraulic systems, coolant system, chip conveyor and CNC control should all be checked.

For long-bed machines, buyers should also inspect the machine’s alignment and axis movement across the complete travel range. A machine that has been heavily used for long-part machining should be evaluated carefully before purchase.

The overall value of a used QUICK TURN NEXUS 350 therefore depends on more than its model and year. Condition, configuration, bed length, hours, included tooling and accessories, service history and installation requirements should all be considered when evaluating a specific machine.

HOW MUCH DOES A USED MAZAK QUICK TURN NEXUS 350 COST?

The price of a used MAZAK QUICK TURN NEXUS 350 can vary substantially depending on year, bed length, machine condition, spindle hours, control generation, chuck size, tooling, tailstock, chip conveyor and other installed options.

Public used-machine listings provide examples of the price variation. One documented 2008 MAZAK QUICK TURN NEXUS 350-II/1500 is currently listed at $64,500, with a 60.672-inch machining length, 15-inch hydraulic chuck, 40/30 HP spindle, MAZATROL NEXUS Matrix control, tailstock, chip conveyor and ToolEye. This is an asking price for one particular machine and should not be treated as a general market value for every QTN 350.

Configuration is one of the most important factors affecting price. A long-bed machine capable of machining approximately 60 or 80 inches is not directly comparable with a shorter 26-inch-bed machine. The included workholding and production accessories can also make a substantial difference.

Spindle condition should be evaluated carefully. Buyers should check spindle noise, vibration, temperature, runout, bearings and performance under load. A machine with a healthy spindle can have a very different ownership cost from one requiring major spindle repair.

The condition of the turret and axis system is equally important. Buyers should verify turret indexing, tool clamping, X- and Z-axis movement, ballscrew condition and positioning accuracy.

The CNC control should also be inspected. Display condition, memory, drives, operator controls, alarms, communications and program storage should be checked before purchase.

Included accessories can significantly increase the practical value of a used machine. A chip conveyor, hydraulic chuck, programmable tailstock, tool presetter, tooling package and other production equipment can reduce the additional investment required to place the machine into service.

Transportation and installation costs should also be included in the purchase budget. Depending on the bed length and configuration, the machine can weigh approximately 15,000–17,000 pounds or more, and long-bed configurations require substantial floor space and professional rigging.

For that reason, buyers should compare used MAZAK QUICK TURN NEXUS 350 machines based on the complete machine package, not simply the advertised machine price. Year, configuration, bed length, spindle condition, control, tooling, workholding, accessories and service history all contribute to the final value of the machine.
