GT428-5XG (Double-Column 5-Face Machining Center)

The GT428-5XG from PRIMINER, presented by Maxinren, is a robust double-column 5-face machining center engineered for precise, efficient processing of large and heavy workpieces. This advanced CNC machine features an expansive table, a powerful spindle, and an auto-indexing milling head, delivering maximum flexibility and productivity for demanding industrial applications.

Key features of the GT428-5XG include Heidenhain linear scales on the X, Y, and Z axes for superior accuracy, and four linear guides on the Z-axis to ensure exceptional rigidity and precision. The Z-axis is equipped with dual-drive technology and two ball screws, providing highly dynamic machining capabilities. Three linear guides on the Y-axis further enhance stability, while an extra-wide machine column and base guarantee outstanding rigidity and support for heavy-duty machining tasks.

With its innovative design and advanced features, the GT428-5XG 5-face machining center optimizes performance, accuracy, and durability, making it an ideal solution for large-scale industrial production requirements.
