Product Characteristics

• The machine features a gantry frame fixed structure with a moving worktable.
• High-Rigidity Beam: The beam adopts a rectangular large cross-section arch design. The height-to-width ratio is optimized through simulation analysis, significantly enhancing its bending and torsional resistance, ensuring precision stability.
• Large Cross-Section Ram: The ram has a cross-sectional size of 420x420mm, supported by four linear guide rails in a semi-enclosed arrangement. This provides high-strength support with low friction resistance, ensuring zero creep at low speeds, minimal vibration, fast response, and excellent dynamic and static performance, low maintenance requirements, and long service life.
• Multiple Support Table: The table is supported by multiple closely spaced slides, ensuring stable and reliable load-bearing performance with excellent precision retention.
• Various Drive OptionsConfigurable with belt drive, geared head, electric spindle, and automatic right-angle milling head.
• Gear-driven SpindleFeatures a BT50 interface with a maximum speed of 6000rpm and an output torque of up to 1331Nm. The gearbox and main motor are separated from the spindle, effectively minimizing accuracy issues caused by heat generation.
• Motorized spindleHigh-power, heavy-duty BT50-10000rpm electric spindle that delivers high torque, high speed, and low vibration, providing an exceptional machining experience.
• Belt-driven SpindleUtilizes a BT50-6000rpm high-speed spindle unit, offering efficient cutting performance.
• Thermal ControlStandard with an oil cooling system to reduce spindle temperature, prolong bearing life, and minimize the impact of thermal deformation on machining accuracy.
• Three-Line Rails: All three axes (XYZ) use heavy-duty roller linear guide rails, which are easy to maintain, have low friction resistance, fast response from moving parts, zero creep at low speeds, and excellent dynamic and static performance.
• Belt Drive: The XY-axis motors use belt reduction to increase transmission torque, reduce load inertia, improve drive performance, and provide simple and cost-effective maintenance.
• Gear Drive: The motor is reduced through a low-backlash reducer, increasing torque transmission. Combined with larger lead screws, this ensures fast drive speeds, stable performance, and high precision (X-axis ≥ 4200mm / Y-axis ≥ 3700mm).
• Nitrogen Balancing: The Z-axis drive system uses a servo motor directly coupled to a ball screw, with a dual-cylinder balancing system on both sides of the ram to ensure smooth reversal of Z-axis feed and fast dynamic response.
• Thermal Compensation: The ball screw features a pre-tensioned structure at both ends, effectively eliminating precision loss caused by thermal expansion.
• Spiral Chip Conveyor: One set on each side of the worktable, with a 120mm screw diameter and large square steel cross-section, quickly expelling chips outside the machine.
• Chain-type Chip Elevating Conveyor: Located at the machine’s end, with a 45-degree incline, wider chain plate, and sawtooth scraper bars, quickly collecting chips into the small chip conveyor.
• Small Chip Conveyor: Collects and transports chips.
• Coolant Tank: Multi-layer filtration system to filter impurities and ensure smooth machining.
