Haas Automation, Inc. GR-712 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large table measuring 144" by 72" capable of supporting workpieces up to 6,000 lbs, making it suitable for heavy-duty machining tasks. It is equipped with a vertical spindle offering a CT40 taper with an optional BT40 taper, providing versatility for tooling systems. The spindle delivers a maximum speed of 8,100 RPM and a 15 HP motor rated for 30 minutes, ensuring ample power for diverse milling, drilling, and boring operations. The machine operates on 3 linear axes (X, Y, Z) with travels of 145", 85", and 11" respectively, all running at a maximum feed rate and rapid traverse of 800 inches per minute, allowing for efficient and precise material removal. Tooling is handled via a 10-position carousel tool changer, optimized for quick tool changes but without pallet changing capabilities. The design excludes a U axis, focusing on a streamlined 3-axis machining process. This machine’s robust size, heavy load capacity, and powerful spindle motor make it ideal for large-scale machining in industries demanding high precision and durability such as aerospace, power generation, and heavy machinery manufacturing. The CT40 and BT40 spindle tapers are standard in CNC machining, with BT40 offering balanced, stable, and metric-based tooling compatibility, suitable for medium to heavy-duty milling applications. Overall, this machine provides a strong combination of table size, spindle power, and travel capability for demanding vertical machining center applications.
