Gmc-ar/gmcu-ar

Overview

Model Gmc-ar/gmcu-ar is listed at https://www.zayer.com/en/product/gantry/gmc-argmcu-ar/21. Drives of X,Y,Z axes are specified as X: R / 6, Y: R / 4, Z: B / 80. Positioning and repeatability accuracy - mm are 0,008/4.000 and 0,005/4.000. Working dimensions include moving cross beam displacement 1.200 (1.700-2.200)* mm, table length 5.000  31.000 mm, table width 2.000 (2.500-3.000-3.500)* mm, distance between columns 3.300 (3.800-4.300-4.800)* mm, longitudinal travel 4.000 - 30.000 mm, cross travel 4.050 (4.550-5.050-5.550)* mm, vertical travel 1.250 (1.500)* mm, and max. distance from table to spindle nose 2.015 (2.515-3.015)* mm. Axis capacities and power figures are Working Feed - mm/min: 6 - 10.000, Rapid feed - mm/min: 25.000, Power - kW: 60 (with quill 40), and Speed of the spindle head - rpm: 4.500. Tool magazine capacity is 30 (40 - 60)*, allowed weight on the table is 15.000 / m2, and approx. net weight is 70.000 - 260.000 kg. Designed for machining large-format parts and assemblies where long longitudinal travel and high table load capacity are required. The table is rated for 15.000 / m2 and the machine net weight range (70.000 - 260.000 kg) reflects a heavy-duty structure suited to high-material-removal operations. Drive and performance details support both heavy traverse and precise vertical positioning: X and Y axes use rack drives (X: R / 6; Y: R / 4) for long, robust travel while the Z axis uses a ball screw (Z: B / 80) for vertical accuracy. Spindle power is 60 kW (with quill 40) and spindle head speed is 4.500 rpm; working feed is 6 - 10.000 mm/min with a rapid feed of 25.000 mm/min. Tool handling is provided by a tool magazine of 30 (optional 40 - 60), enabling automated tool changes for production or R&D cell integration. Configuration options for table size, travel ranges and moving cross beam displacement make this machine suitable for heavy industries and applications such as large mold and die machining, structural frames, turbine casings and other large workpieces where a mix of high removal rates and repeatable positioning is required. Positioning accuracy is 0,008/4.000 mm with repeatability 0,005/4.000 mm, supporting precision finishing after roughing passes.
