C.R. Onsrud Inc. 6 SERIES - WIDE PRO SERIES VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features **dual main spindles**, each with a vertical orientation and equipped with **HSK 63F tapers**. The spindles can operate up to **24,000 RPM** and deliver a power rating of **18 HP (30-minute rating)**, enabling high-speed, high-precision machining. The machine employs a **12-station automatic tool changer (ATC)**, facilitating efficient tool switching without manual intervention. It operates with a **3-axis configuration (X, Y, Z)**, with an optional 4th axis capability; the axes travel distances are X: 2,500 mm, Y: 89 inches (~2,261 mm), and Z: 11 inches (~279 mm), all with a maximum feed rate of 2,500 inches per minute and rapid traverse rate of 3,500 inches per minute. The absence of a rotary table or pallet changer indicates the machine is optimized for workpieces not requiring rotary indexing or quick part swaps. Its spindle taper standard, HSK 63F, supports high rigidity and precision, suitable for demanding applications in aerospace, automotive, and mold making. The combination of high-speed spindles, precise axis control, and multi-tool ATC ensures versatility for complex milling operations, including metals and advanced composites. The fast feed and rapid traverse rates enhance productivity and surface finish quality during machining cycles. This setup is ideal for precision vertical milling tasks requiring dual simultaneous spindle use and quick tool changes, without rotary or pallet handling features.
