2020 ACER EMC2240 VERTICAL MACHINING CENTERS

Technical Description

The Acer EMC-2240 is a 3-axis vertical machining center from Acer Machine Tools, a Taiwanese builder with strong distribution in the North American market. The EMC (Economy Machining Center) designation places this model in Acer's entry-to-mid tier, targeting job shops, training facilities, and general production environments where proven reliability and cost-effective operation are the primary requirements. Axis travels are 40" (1,016mm) in X, 20" (508mm) in Y, and 20" (508mm) in Z. The 42" × 19.6" worktable supports a maximum load of 1,320 lbs (600 kg) and features three T-slots spaced 9.9" apart at 0.708" (18mm) width. Spindle nose-to-table distance ranges from 4.72" to 24.8". The spindle motor is rated at 15 HP (30-min) / 10 HP (continuous) and drives through a #40 taper (CAT40/BT40) across a speed range of 60–8,000 RPM. The 8,000 RPM maximum is characteristic of this economy-class platform and is best suited to conventional steel, cast iron, and aluminum milling at moderate speeds. Rapid traverse is 945 IPM on all three axes, with a 1,181 IPM high-speed option available. Cutting feed rate reaches 200 IPM. Positioning accuracy is ±0.0002" with repeatability of ±0.00012". The standard ATC holds 20 tools, with a 24-tool configuration also available. Machine footprint is 98" × 94" with an overall height of 102", and net weight is approximately 12,100 lbs (5,489 kg) — a robust casting weight for this travel class that contributes to machining stability and vibration damping under heavy cuts.
