Product Detail

Fixed Gantry CNC Machining Center GMC Series | Heavy-Duty Vertical Milling, Drilling & Boring (BT40/BT50)

Engineered for mold makers and heavy machinery manufacturers, the GMC Series combines a fixed gantry frame with a fully connected beam and double-column layout to eliminate vibration and maintain micron-level accuracy under heavy cutting loads. Three models cover X-axis travels from 1300mm to 2000mm, with table capacities up to 3000kg.

Equipped with C3-grade ground ball screws, 45mm roller guides (X/Y) and hard rails (Z), the machine ensures rapid traverses up to 24m/min and repeatability of ±0.004mm (JIS standard). Belt-type spindles (BT40/BT50, 6000–8000rpm) are driven by SYNTEC or FANUC servo systems, handling everything from aggressive roughing to fine finishing in one setup.

Key Highlights:

Ultra-Rigid Fixed Gantry: Integral beam, double columns, and bed connection for maximum anti-vibration and thermal stability.
Precision Motion: C3 ground screws + 45 roller guides deliver ±0.005/300mm positioning and ±0.004mm repeatability.
Heavy-Duty Cutting: Hard rail Z-axis, 15/18.5KW spindle motor, BT50 option for demanding roughing.
Versatile Machining: Mill, drill, tap, bore — ideal for large molds, dies, and structural components.
Global CNC Options: SYNTEC (standard) or FANUC control, 24m/min rapid traverse, 1–10m/min cutting feed.

Product Description

1. Overview

The GMC Series Fixed Gantry CNC Vertical Machining Center is designed for manufacturers requiring exceptional rigidity and precision on large workpieces. The fixed gantry frame — with beams, double columns, and machine sides rigidly connected — provides a stable platform for both heavy roughing and high-accuracy finishing. It efficiently performs milling, drilling, tapping, and boring, making it indispensable in mold & die, energy equipment, aerospace jigs, and general machinery production.

3. Core Design Advantages

① Fixed Gantry Frame — Maximum Structural Rigidity

The integral connection between the beam, double columns, and both sides of the machine bed forms a closed-loop rigid frame. This design eliminates deflection under heavy cutting forces, suppresses vibration, and maintains geometric accuracy over years of operation. Ideal for large mold cavities and thick-plate machining.

② Precision Transmission System

C3 Grade Ground Ball Screws (4012/5012) on all 3 axes ensure backlash-free motion and micron-level positioning.
45mm Roller Linear Guides on X and Y axes provide high load capacity and smooth rapid traverses up to 24m/min.
Hard Rail Z-Axis absorbs heavy cutting thrust, preventing spindle deflection during deep roughing.

③ High-Performance Spindle Options

Belt-driven spindle with BT40 (8000rpm, 11–15KW) or BT50 (6000rpm, 15–18.5KW) taper. BT50 handles large-diameter cutters and heavy roughing; BT40 delivers high-speed finishing. SYNTEC or FANUC servo motors ensure consistent torque output.

④ Comprehensive Machining Capability

One machine performs roughing and finishing of milling, drilling, tapping, and boring. Eliminates multiple setups, reduces handling errors, and shortens lead times for complex parts.

⑤ Reliable & Durable

Built for continuous industrial operation. Imported seals, precision-ground components, and robust castings ensure long service life with minimal maintenance.

4. Application Scope

Mold & Die Manufacturing: Large injection molds, die-casting molds, stamping dies, jigs, and fixtures.
Heavy Machinery: Equipment bases, structural frames, precision housings, and large brackets.
Energy & Infrastructure: Wind power components, transformer parts, valve bodies.
General Precision Machining: Multi-process parts requiring tight tolerances and superior surface finish.
