Atrump E320 VERTICAL MACHINING CENTER

This CNC vertical machining center features a **41" x 16" work table** capable of supporting workpieces up to **1,500 lbs**, with optional support for both index and rotary tables. It is equipped with a vertical spindle with a standard **CAT 40 taper** and an optional **BT 40 taper**, delivering a standard top speed of **6,000 RPM** with an optional upgrade to **8,000 RPM**. The spindle motor offers a powerful **10 HP (30-min rating)** with an optional increase to **15 HP**, providing robust cutting capability. Tooling is managed via a 16-position armless automatic tool changer (ATC), which can be optionally expanded to hold 20 tools, with a tool change time of approximately 9 seconds. The machine operates on a **3-axis configuration** (X, Y, Z axes) with an optional 4th axis available. Axial travel distances include **33.9" (X), 20" (Y), and 24" (Z)**, each with a maximum feed rate of **150 IPM** and a rapid traverse rate of **360 IPM**. The machine is capable of full 360° rotation on the B-axis. The spindle tapers comply with industry standards, ensuring compatibility with a wide range of tooling; CAT40 and BT40 tapers differ primarily in pull stud design but share the same taper angle of 7/24 (approximately 7°), providing a balance of rigidity and versatility. The armless ATC reduces tool change interruptions, enhancing machining efficiency. This setup accommodates high-precision milling suitable for heavy workpieces and complex three- or four-axis machining tasks, achieving high accuracy and productivity in metalworking and manufacturing environments.
