High-Precision, High-Speed Medical Machining Center

The Vertical Center Nexus (VCN) Compact vertical machining center looks to meet and exceed the medical industry’s growing demand for lean manufacturing through the use of small-footprint machines with strong cutting capabilities.

The Vertical Center Nexus (VCN) Compact vertical machining center looks to meet and exceed the medical industry’s growing demand for lean manufacturing through the use of small-footprint machines with strong cutting capabilities. The machine efficiently and accurately produces the medical industry’s typically small, extremely complex, and high-precision components requiring superior surface finishes. The compact size maximizes the use of valuable shopfloor space, allowing the grouping of multiple machines, closely together, for optimizing part production operations.

Mazak engineers built the VCN Compact with components and features specifically for optimizing that process. These include high-rpm, high-power spindles, extremely fast machine axis travels, and high-performance CNC machine controls, all combined on a compact, yet heavy and robust machine base requiring only about 47.7ft² (59.1" x 116.3") of floor space. Its space-saving size makes the VCN Compact the smallest vertical machining center in its class equipped with the strength of 40-taper spindles to handle the toughest medical materials.

Additionally, to better accommodate specific high-speed medical machining needs, Mazak offers the VCN Compact in 3- and 5-axis models, both of which can be equipped with either high-speed 12,000rpm or 20,000rpm spindles. The 5-axis model comes standard with a compact NC rotary/tilt table for high-precision contouring. The rotary/tilt table provides backlash-free, high-accuracy C-axis and A-axis movement that further adds to the machine’s ability to produce superior part surface finishes.

A double-arm-style automatic tool changer quickly exchanges tools in the VCN Compact’s spindle in just 1.3 seconds. In addition, for a machine of its size, the VCN Compact provides as much tool storage capacity as possible for part production versatility and continuous operation. The machine’s tool magazine accommodates 20 tools measuring up to 3.15" in diameter and as much as 7.8" long. Mazak also offers the option to increase that capacity to 30 tools for even more versatility and continuous operation.
 

Stable, Fast, Precise

  • Three linear axes rapid traverse at speeds up to 1,417ipm and feeds at 315ipm
  • Ample machine axis travels provide 19.69", 15.75", 12.99" in X, Y, Z
  • Machine linear axes ride on Mazak’s MX Hybrid Roller Guide System working in tandem with double-end supported ballscrews
  • Mazak MX Hybrid Roller Guide System dampens vibration to extend tool life, handle higher load capacities, accelerate and decelerate faster to shorten cycle times, consumes less oil for greener operations
  • Tables rotate in the C-axis at speeds up to 100rpm
  • Tilt in the A-axis is from -20° to +120° at 75rpm

Advanced Controls

  • 5-axis VCN Compact uses Mazak’s Matrix 2 CNC control
  • 3-axis VCN Compact uses Mazak’s Matrix Nexus CNC control
  • 5-axis Spline Interpolation Function enables the Matrix 2 to reduce cycle times by optimizing corner decelerations
  • 5-axis Spline Interpolation creates seamless toolpaths from long block-by-block programs
  • Matrix 2’s Volumetric Compensation works to compensate volumetric axis position errors within the full stroke area of the VCN Compact
  • Matrix 2 offers EIA/ISO and programming for versatility and user-friendly operation
