The Skymach BR3018 CNC Gantry Machining Center is an upgraded heavy-duty double-column bridge machining center featuring an extra-wide 1,600 mm worktable, 1,800 mm gantry portal width, and 2,000 mm Y-axis cross travel. Built on an ultra-heavy HT300 cast iron foundation weighing 17.5 t (17,500 kg), the BR3018 combines heavy 55mm linear roller rails on X and Y axes with induction-hardened rectangular box ways on the Z-axis, powered by a high-torque 22 kW BT50 spindle drive.
Comprehensive Machining Capabilities
- Wide-Format Heavy Milling: The 1,600 mm wide worktable easily accommodates large multi-cavity injection molds, stamping die shoes, and large chassis parts without overhang.
- Extreme Roughing Rigidity: Z-axis induction-hardened box ways with hand-scraped Turcite-B lining absorb heavy cutting shocks during high-feed face milling and deep pocketing.
- ZF Reduction Gearbox Compatibility: Optional German ZF 2-speed reduction gearbox (4:1 ratio) provides colossal torque output at low RPMs for machining hardened tool steels and titanium alloys.
Key Engineering Highlights
- 1600mm Wide High-Payload Worktable: Supports massive workpieces up to 6.0 t (6,000 kg) with 7 continuous 22mm T-slots.
- Monolithic HT300 Cast Bridge: Heavily ribbed portal door bridge and base structure eliminate dynamic deformation under severe cutting loads.
- Hydraulic Counterbalance System: Counterbalances the heavy vertical ram to ensure smooth micro-stepping and prevent ball screw backlash.
