Acer E-MILL 3VK VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a **50" x 10" manual table** with an optional width of 9", capable of supporting workpieces up to **1,000 lbs**. It is equipped with a **vertical spindle with an R8 taper**, standard in many milling applications, facilitating rigid, precise tool holding. The spindle delivers up to **4,500 RPM** with a 3 HP rating (upgraded option to 5 HP), suitable for various milling tasks requiring moderate speeds and power. The single manual tool carrier supports one tool, enabling simple setups without automatic tool changes, ideal for versatile or prototyping work. The machine operates with **five axes of movement**: linear travels along Y and Z axes extend 16" each, while rotational axes A and B provide 90° and 45° of motion, respectively, enhancing the capability for complex part contours and multi-sided machining. The X-axis travel is unspecified but presumed complementary. Rapid traverse and maximum feed rates are not listed but likely optimized for precision. The R8 spindle taper conforms to a 3.5" per foot taper ratio (approximately 16.26° angle), known for secure clamping and ease of tool changes via drawbar tightening. This combination of vertical spindle, five axes, and robust table size makes the machine well suited for precision milling of medium-sized components, accommodating sizable and heavy workpieces in industries such as toolmaking and prototyping. Manual tool handling limits high-speed production but offers flexibility for specialized machining operations requiring accuracy and adaptability.
