The GX 1300 and GX 1600 Performance VMCs offer large-scale machining capability for automotive, aerospace, medical, mold and die and general applications. These VMCs feature a thermally-stable spindle; a C-frame, fixed-column design; and fixed pre-tensioned, double-nut ballscrews on all axes. They have two guideways and six guide trucks on their X and Z axes and two guideways and four guide trucks on their Y axis. The linear guide and truck configuration is said to provide added stiffness and effective vibration damping.   The GX 1300 has X-, Y- and Z-axis travels of 51.18" × 27.55" × 25"; the GX 1600 has travels of 62.99" × 27.55" × 25". The table sizes for the GX 1300 and GX 1600 are 56" × 27.55" and 63.93" × 27.55", respectively. Table weight capacity for both is 3,300 lbs.   Both versions have a 34.8-hp spindle that provides 110 foot-pounds of torque and speed of 10,000-rpm (an optional 12,000-rpm spindle is available). Their 30-tool, side-mount/swing-arm ATC features random access, bidirectional indexing and chip-to-chip time of 4.5 seconds.

    The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.

    Years of trial and error combined with the appropriate machining technology allow this company to produce custom parts made of alumina, zirconia, boron nitride and other advanced ceramic materials. One example of key machining technology is a five-axis machining center used exclusively to produce the complex, tightly toleranced geometry that fire-hardened workpieces require.
