The TongTai HG-800 is a horizontal machining center featuring a robust 4-axis configuration with travels of 44" (X), 38" (Y), and 34" (Z), plus a full 360° B-axis rotation for versatile machining capabilities. It supports a large table measuring 32" x 32" and can handle workpieces up to 3,600 lbs, making it suitable for heavy-duty manufacturing tasks. The horizontal spindle utilizes a #50 taper with a maximum speed of 6,000 RPM powered by a 35 HP motor rated for 30 minutes, providing sufficient power for medium-to-large part machining. Tool handling is managed by a 60-tool Automatic Tool Changer (ATC) with a fast tool change time of 2.1 seconds; an optional expansion increases capacity to 240 tools. The machine also includes a standard pallet changer with two pallets to support efficient production cycles. Rapid traverse rates reach 787 inches per minute along all linear axes, facilitating fast repositioning and reduced cycle times. The model does not feature U-axis capability or rotary/support index tables, focusing on core horizontal machining functionality. Overall, the HG-800 balances large work envelope, substantial workpiece capacity, and productive tooling automation, making it well-suited to applications requiring precision horizontal milling, drilling, and boring operations on heavy and large components.
