Vertical Center Nexus Compact 5X VMC

December 01, 2013

Mazak now offers its space-saving, highperformance VERTICAL CENTER NEXUS COMPACT 5X Vertical Machining Center as part of a self-contained, prefabricated automated cell that provides efficient, lights-out manufacturing for small-to-medium sized parts. The cell incorporates, in addition to the full 5-axis VMC, a standalone robot and palletizer system for automated processing of up to 72 individual workpieces.

The automated cell handles a wide scope of workpiece sizes measuring up to 3.9" wide x 3.9" deep x 3.9" tall (75mm x 75mm x 75mm) and weighing as much as 8.8 lbs (4 kg). For maximum production within a minimal amount of manufacturing floor real estate, the VCN COMPACT Automation Cell occupies 59" x 116.3" (1,498mm x 2,946mm) of floor space and the robot with stacker only 48" x 60" (1,219mm x 1,524mm).

Operators, from outside the automated cell, use a two-position rotary carousel to load and unload workpieces mounted on System 3R pallets for storage in the cell's 72- position magazine. A FANUC LRMate 6-axis robot with two-jaw parallel gripper accesses any position in the pallet magazine, as well as the load/unload turntable, to load workpiece into the machine from either location for immediate production.

Once parts are loaded into the VERTICAL CENTER NEXUS COMPACT, which is available in 3- and 5-axis versions, the machine delivers absolute precise machining capability and superior part surface finishes. For power and versatility, the machine's robust, high torque 12,000-rpm, 25-hp, CAT 40 spindle provides the aggressive performance required for tough materials, such as stainless steel, Inconel and titanium. An optional 40-hp, 20,000-rpm spindle, or 42,000-rpm, HSK E40 ultrahigh-speed spindle, are both also available.

Reduced part cycle times result from the machine's three linear axes that attain high-speed rapid traverse rates of 1,417 ipm (36 m/min) and fast feedrates of 315 ipm (8 m/min). Plus, the VERTICAL CENTER NEXUS COMPACT accommodates 20 tools in its tool magazine (30 tools optional) to further increase part production versatility.

For rigid and precise 5-axis machining, Mazak's rotary/tilt table on the VERTICAL CENTER NEXUS COMPACT is constructed with durable high-speed, backlash-free roller cam drive technology, allowing the table to rotate and tilt at speeds of 100 rpm and 75 rpm, respectively. The table, with an O.D size measuring 3.94" (100mm) and I.D. of 1.57" (40mm), tilts at angles from -20 degrees to 120 degrees and provides a holding torque of 249 ft-lbs and machining torque of 63 ft-lbs.

The VERTICAL CENTER NEXUS COMPACT features Mazak's MX Hybrid Roller Guide System to deliver levels of durability and reliability that result in long-term accuracy. The MX Hybrid Roller Guide System dampens vibration to extend tool life, handles higher load capacities, accelerates and decelerates faster to shorten cycle times, eliminates tramp oil in the coolant by utilizing a greener grease-based lubrication system, and lasts longer with less required maintenance.

Mazak equips the VERTICAL CENTER NEXUS COMPACT with its advanced MATRIX 2 CNC control specifically for optimized 5-axis machining (3-axis machine versions are equipped with Mazak's MATRIX NEXUS 2 CNC control). Within the MATRIX 2 control are both enhanced hardware and software functionalities that make the control easy to use while also delivering high accuracy and increased productivity. Control hardware performance is much faster with higher processing speeds for small increment operation, and a 5-axis spline interpolation function included in the control's software provides smooth toolpaths from long block-by-block programs, easy tool vector control and shorter cycle times as well as superior 5-axis surface finishes.

Related Glossary Terms

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • computer-aided manufacturing ( CAM)

    computer-aided manufacturing ( CAM)

    Use of computers to control machining and manufacturing processes.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • inches per minute ( ipm)

    inches per minute ( ipm)

    Value that refers to how far the workpiece or cutter advances linearly in 1 minute, defined as: ipm = ipt 5 number of effective teeth 5 rpm. Also known as the table feed or machine feed.

  • interpolation


    Process of generating a sufficient number of positioning commands for the servomotors driving the machine tool so the path of the tool closely approximates the ideal path. See CNC, computer numerical control; NC, numerical control.

  • machining center

    machining center

    CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.

  • parallel


    Strip or block of precision-ground stock used to elevate a workpiece, while keeping it parallel to the worktable, to prevent cutter/table contact.

  • rapid traverse

    rapid traverse

    Movement on a CNC mill or lathe that is from point to point at full speed but, usually, without linear interpolation.

  • tramp oil

    tramp oil

    Oil that is present in a metalworking fluid mix that is not from the product concentrate. The usual sources are machine tool lubrication system leaks.
