High-Speed Gantry Machining Center
High-Speed Gantry Machining Center
Engineered specifically for small-scale mold processing and precision component manufacturing, the CHARLES DC Series delivers unparalleled structural rigidity and exceptional machining stability. With a robust bridge-type gantry architecture, this series is the ultimate solution for high-speed, high-accuracy industrial operations.
Key Features & Structural Advantages
- High-Rigidity Gantry Architecture: The machine's main structure and crossbeam are cast from premium Meehanite iron and undergo complete stress-relief heat treatment. This effectively eliminates internal casting stress, ensuring long-term deformation-free stability.
- Heavy-Duty Linear Guideways: The X, Y, and Z axes are fully equipped with heavy-duty roller-type linear guideways, allowing the machine to withstand immense loads while maintaining an incredibly low friction coefficient.
- High-Speed Feedrates: The rapid traverse rate for both the X and Y axes reaches up to 36 m/min, perfectly satisfying the fast-paced requirements of modern high-speed cutting applications.
- Advanced High-Speed Spindles: The standard configuration comes with a #40 direct-drive high-speed spindle designed for elevated RPM demands. For specialized machining, a high-performance built-in type spindle is also available as an option.
- Ultra-Fast Tool Transitions: Features an optimized automatic tool changer (ATC) capable of completing rapid tool-to-tool switches in just 2.3 seconds.
- Optimized Internal Rib Design: The structural castings adopt a box-type layout coupled with scientific internal rib reinforcement to optimize mechanical rigidity and suppress dynamic cutting vibrations.

Premium Tool Magazines & System Accessories
Various High-Speed Tool Magazines
- Precision Cam Indexing: The tool magazine utilizes a reliable cylindrical cam indexing mechanism that ensures fast, seamless, and highly stable tool swaps.
- Double Servo-Drive Magazine Upgrade: Specifically engineered with an extra servomotor dedicated to the tool compartment. This layout dynamically eliminates vibration on the column caused by inertial forces during high-speed tool disk rotation, preserving absolute machining accuracy.
High-Efficiency Chip & Coolant Handling Devices
- Coolant Ring: Positions a circumferential blast around the spindle nose to flush away chips directly from the cutting zone, enhancing cooling efficiency and surface finish.
- Coolant Through Spindle (CTS): Delivers pressurized coolant straight through the cutting tool core. Ideal for deep-hole drilling, pocket milling, and drastically extending tool lifespan.
- Coolant Flushing System: Strategically outfits the internal cabin with at least 3 high-volume flushing nozzles on each side of the table to thoroughly wash chips into the conveyor.
- Boat-Type Chip Conveyor: Continuously evacuates high-volume chip accumulation straight out into an external collection bucket, keeping your internal workspace spotless.
