The LEI3021 is a heavy-duty fixed table gantry machining center designed for high-precision machining of large-scale metal components. It adopts a robust gantry frame structure with high-strength cast iron (HT300) bed, column, and crossbeam, providing exceptional rigidity and stability for heavy-load cutting operations.

The machine features a 3200*1800mm worktable with a maximum load capacity of 8 tons. The XYZ axes have a travel range of 3200*2100*850mm, equipped with high-precision C3 class ball screws (X: Φ63mm, Y/Z: Φ50mm) and imported roller linear guides, ensuring smooth and accurate movement. The rapid feed rate is 15m/min for X/Y axes and 12m/min for Z axis, improving production efficiency.

The spindle uses a BT50 taper with a maximum speed of 6000rpm, powered by an 18.5kW Fanuc AC servo motor. It adopts a belt drive system with nitrogen counterbalance, ensuring stable spindle operation and long service life. The machine is controlled by the Fanuc MP5 CNC system, offering advanced programming and diagnostic functions for complex machining operations.

Equipped with a full set of auxiliary systems: a 50L/min coolant pump, spiral chip removal system, quantitative lubrication system, and IP54 protected CNC cabinet with air conditioning. It also includes safety protection devices such as anti-collision mechanisms, overload protection, and warning lights, ensuring safe and reliable operation.

• Install the machine on a reinforced concrete foundation with a bearing capacity of 8~10T/m².
• Connect to a three-phase AC380V±10% 50Hz±2% power supply, and follow local electrical safety regulations for proper grounding to ensure safe operation.
• Prepare a stable air supply of ≥0.6MPa and ≥500L/min for pneumatic functions.
• Before operation, check the lubrication system, coolant level, and tool clamping to ensure normal function.
• Confirm workpiece clamping, tool installation, and program correctness before starting automatic machining.
• Keep hands and foreign objects away from the spindle, worktable, and chip removal system during operation.
• Regularly clean chips from the worktable, guideways, and chip removal system to maintain accuracy and prevent wear.
• Perform periodic calibration of the machine tool accuracy to ensure processing quality.
• When the machine is idle for a long time, turn off the main power and carry out rust prevention and dust protection.
