It can process a wide range of metals, including carbon steels, alloy steels, aluminium alloys, mould steels, and cast irons; it also works well with high-strength composite materials. Provides stable, fast processing solution for heavy machinery, large-mould fabrication, Energy equipment, Ship-building industry and Railway transport sector.
Product Advantages
Extra-Large Processing Range & Strong Load-Bearing Capacity
GMC3220 as an advanced large-machining centre has a spacious workspace of 3000x1800 mm and can support heavy loads up to 6 tons; this design specifically accommodates extra-large parts. X/ Y /Z-axis displacement range: 3200 x 2200 x1000 mm; Gantry Width: 2000mm ; Passage Height : 1300 mm; Can stably machine large work-pieces such as large mold bases, wind power brackets and ship-shaped components . To adopt a fixed-beam, moving-table structure to increase its rigidity against vibration and deformation when handling large-sized parts during cutting operations.
Modular Configuration & Versatile Processing Capability
The GMC 3220 uses a modular structure to be configurable in different ways by customers . An additional option of a BT-50 spindle can be selected; it may use direct-drive or gearboxes for both high-speed cutting and heavy-duty purposes. Standard arm-tool-storage system, tool-changing time is within 3s, capable of automatic operation at multiple process links: Milled parts, drilled holes, Bore-tap hole machining, Tapping, and curve surface grinding[1-6]. Optional right-angle milling heads, general-purpose tools that come with the ability to rotate in place, and automatic-relocating tool holders have expanded their applications more extensively.
High Precision & Intelligent Error Compensation
The main parts include the gantry beam, columns and the bed, which are all made of high-grade HT300 grey cast iron by using casting technology after an artificial-aged-Vibration-aged dual-age-stress removal process with a finite-element-analysis optimization design for excellent rigidity and precise long-term performance. With the help of THK and HIWIN heavy-duty linear guides, as well as preloading C3-grade precision ball screws, a laser real-time online measurement system combined with space error automatic adjustment mechanism have been introduced. The Positioning error is less than ±0.0075mm (X/Y) and Z; Repeated measurement errors are below ±0.015mm, respectively.
User-Friendly Operation & Comprehensive Quality Assurance
Has a simple user interface of the CNC system (Fanuc, Siemens or GSK) and supports three axis connection; Can be performed offline via DNC and automatically diagnose faults. It has an automatic concentrated lubrication System and dual-spiral chips discharge line to extend the lifespan of parts while guaranteeing 24 hours' continuous operation reliably . CE, ROHS and ISO 9001 certification are all in place; after dynamic inspection and test cut confirmation at the factory, it can be delivered as required.
