2008 AMERA SEIKI A3R VERTICAL MACHINING CENTERS

Technical Description

The Amera Seiki A3R is a 3-axis vertical machining center from Amera-Seiki's A series, representing the R-designated variant of the A3 platform. The R suffix on Amera-Seiki models typically denotes an enhanced or revised configuration, potentially including extended axis travels, higher spindle speed options, or additional standard features compared to the base A3 model. The A3R features box-way construction on all axes for high-rigidity cutting of ferrous materials, with a CAT-40 spindle taper and gearbox drive. A Fanuc CNC control and automatic tool changer are standard. The machine was distributed in North America as part of Amera-Seiki's lineup of affordable, rigid Taiwanese VMCs suitable for steel, cast iron, and aluminum machining in job shop and toolroom environments. The box-way design provides excellent vibration damping for interrupted cuts and heavy roughing passes that would be more challenging on linear guideway machines. Detailed OEM specification data for the A3R including axis travel, table dimensions, spindle power, and weight are not broadly documented in publicly available English-language sources. Prospective buyers should confirm all specifications directly with the specific unit's documentation.
