HARTFORD HSA-423EAY VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a large work table sized 157.5” x 86.6” with T-slots measuring 1.1” width by 9.84” pitch, supporting a maximum table load of 26,500 lbs. It offers extensive travel capabilities with an X-axis stroke of 157.5”, Y-axis of 122.1”, and Z-axis of 39.4”, complemented by a spindle-to-table clearance adjustable between 13.8” and 53.2”. The machine’s rigid structure spans a column width of 90.55”, providing stability and accommodating large workpieces. Precision is a key attribute, with a positioning accuracy of ±0.0004” and repeatability accuracy of ±0.0001”, ensuring tight adherence to programmed paths and consistent machining results. High-speed cutting is enabled by a 50 HP spindle motor with a BT 50 taper spindle nose, capable of speeds up to 6,000 RPM. Feed rates are robust, with cutting feed rates of 393.7”/min on X and up to 472.4”/min on Y and Z axes, and rapid traverse rates reaching 787.4”/min on X. Tool handling is efficient, featuring a 32-tool magazine supporting tools up to 44.1 lbs and 4.92” diameter by 15.75” length, suitable for varied machining tasks. The machine operates on a 220 V, 3-phase, 60 Hz electrical supply at 60 KVA, and requires compressed air at 92.5 psi for pneumatic functions. Overall machine dimensions are 511.8” by 267.7”, weighing 81,800 lbs, indicating a heavy-duty industrial CNC milling platform optimized for large-scale, high-precision manufacturing applications.
