HARTFORD HSA-836EAY VERTICAL MACHINING CENTER

Technical Description

The HARTFORD HSA-836EAY Vertical Machining Center is a heavy-duty, high-precision CNC double-column bridge mill designed for large-scale machining applications. It features an expansive X-axis table travel of 314.96 inches, Y-axis spindle head travel of 196.85 inches, and a vertical Z-axis travel of 47.24 inches, supporting large workpieces with a table size of 318.89" x 137.79" and a robust load capacity of 66,000 lbs. The machine’s distance between columns is 165.35 inches, allowing for flexibility and support during machining. Equipped with a BT 50 spindle taper and a gear-type spindle running up to 6,000 RPM, it is powered by a spindle motor delivering between 24.6 to 29 HP, optimized for diverse materials and cutting conditions. The system supports rapid traverse rates of 314.96 IPM (X), 629.92 IPM (Y), and 590.55 IPM (Z), along with cutting feed rates of 236.22 IPM (X) and 393.70 IPM (Y/Z), ensuring high productivity and efficiency. Advanced features include Fanuc OiMF CNC control, a 32-station automatic tool changer, an automatic universal head with A/C axis auto-indexing for five-degree positional adjustment, and an extension head capable of 4,000 RPM. Precision is enhanced by X/Y/Z roller linear guideways and linear scales, with a centralized automatic lubrication system. Additional utilities like spindle air blow, oil coolers, chip conveyor, and oil skimmer improve operation stability and chip management. The machine occupies approximately 340.55" by 82.67" of floor space and weighs around 163,900 lbs, making it suitable for demanding industrial environments requiring large capacity and precision machining.
