DXH50-4218D Heavy-Duty Moving Gantry Machining Center-Qi Fa (Jiangsu) Machinery Co., Ltd.

DXH50-4218D Heavy-Duty Moving Gantry Machining Center is widely used for:

· Large mold machining
· Energy equipment components
· Heavy mechanical parts
· Plate and box type components
· Precision structural parts manufacturing

Heavy-Duty HT300 Machine Structure
The slide, saddle, bed, crossbeam, columns and base use HT300 high-strength cast iron, providing strong structural support and stability during heavy cutting.

High-Torque Spindle Assembly
The spindle assembly uses specialized NSK spindle bearings and is designed for high precision, high performance, high torque and smooth transmission, supporting demanding machining operations.

Modular Spindle Head Configuration
The modular structure supports manual and automatic spindle head changes, with special spindle angle heads available for customer-specific applications such as five-axis machining.

Rigid Servo Feed System
The three-axis feed drives use HNC Huada series AC servo feed motors, supporting rigid and precise ball screw feeding. The guideways also feature automatic lubrication for extended operation.

Reliable Cooling and Chip Removal
A large-capacity cooling pump provides cooling for the spindle, tools and workpieces. A configurable dual-row hinged chip conveyor and chip collection box support efficient chip removal during machining.
