GMC1611 CNC Gantry Machining Center – Detailed English Description
1. General Introduction
The GMC1611 is a heavy-duty, high-precision double-column CNC gantry machining center engineered for large-scale, heavy-cutting, and high-accuracy applications. It integrates a robust cast iron structure, high-rigidity linear guideways, and a powerful spindle, delivering exceptional stability, load capacity, and machining precision for large molds, aerospace components, and heavy mechanical parts.
2. Structural Features
Heavy-Duty Cast Iron Frame: The bed, columns, crossbeam, and headstock adopt high-quality HT300 gray iron with an optimized reinforced rib design. Resin sand casting and multiple stress relief treatments ensure minimal deformation and superior vibration damping under heavy loads.
Double-Column & Crossbeam Design: The fixed double-column and moving crossbeam structure provides high rigidity and stability, effectively suppressing vibration during heavy cutting and ensuring long-term accuracy retention.
Precision Linear Guideways: X/Y/Z axes use heavy-duty linear guideways (X-axis with 4 rails, Y/Z with 2 rails) for low friction, high rigidity, and smooth, rapid movement.
High-Precision Drivetrain: All axes are equipped with high-grade C3 precision ball screws, calibrated via laser interferometer and ball bar testing to guarantee excellent positioning and repeat accuracy.
3. Main Technical Specifications
4. Spindle System
High-Torque BT40/BT50 Spindle: Delivers powerful cutting capacity, ideal for heavy metal removal on steel, cast iron, and aluminum alloys.
Precision Bearings & Oil Cooling: High-precision angular contact bearings and a forced oil cooling system minimize thermal deformation during prolonged high-speed operation, ensuring consistent accuracy.
Optional Through-Spindle Coolant: Enhances deep-hole drilling efficiency and extends tool life.
5. Tool Magazine & ATC
Standard 24-Tool Disc-Type Magazine: Equipped with a reliable automatic tool changer (ATC) for fast tool exchange.
Tool Capacity: Max tool diameter φ78mm (φ120mm adjacent empty), max length 300mm, max weight 8kg (18kg optional).
Quick Tool Change: Reduces non-cutting time and boosts productivity for batch production.
6. Control System
Compatible Controllers: FANUC 0i-MF, SIEMENS 808D, MITSUBISHI M70, or GSK systems.
Core Functions: Full 3-axis interpolation, canned cycles, tool wear compensation, real-time monitoring, and DNC communication for flexible manufacturing.
User-Friendly Operation: Simplifies programming and operation for complex 3D contours and multi-step machining processes.
7. Application Range
Mold Industry: Large plastic molds, die-cast molds, forging molds, and mold bases.
Aerospace & Automotive: Large structural components, box-type parts, and heavy-duty flanges.
General Precision Machining: Suitable for steel, aluminum, cast iron, and alloy steel workpieces in heavy mechanical processing.
8. Optional Configurations
4th/5th axis rotary table for multi-axis machining.
High-speed spindle (10,000–15,000rpm).
Chip conveyor and coolant filtration system.
Automatic door, oil mist collector, and tool setting probe
