TONGTAI HB-500II HORIZONTAL MACHINING CENTER

The TongTai HB-500II is a robust horizontal machining center designed for heavy-duty precision milling. It features a 20" x 20" (500 mm x 500 mm) work table with a maximum load capacity of 1,320 lbs (600 kg), supporting substantial workpieces. The machine has a 4-axis configuration including a full 360° B-axis rotary table with hydraulic locking for exceptional stability under heavy cutting loads. The horizontal spindle utilizes a #50 taper with a top speed of 10,000 RPM, powered by a 40 HP motor rated for 30-minute duty cycles, delivering high torque (up to 420 Nm at 500 RPM) to handle tough materials like cast iron and steel efficiently. Equipped with an Automatic Tool Changer (ATC), it holds 60 tools as standard, expandable to 240, allowing for versatile tooling setups and reducing downtime with a 2.4-second tool change time. The machine includes a standard pallet changer system with two pallets to maximize productivity through continuous loading/unloading operations. The X, Y, and Z axes each offer substantial travels of 32", 28", and 28" respectively, all capable of rapid traverses up to 2,362 inches per minute, enabling fast and precise positioning. The spindle and table system deliver heavy-duty cutting performance with a hydraulic full-circle braking rotary table providing stable machining conditions. This unit is ideal for complex, high-volume manufacturing environments requiring accuracy, flexibility, and durability.
