JW-U500 is a high-performance five-axis linkage machining center, which integrates precision mechanical design, high-quality material selection, advanced processing technology and strict quality control to ensure high stability, high precision and long life of the equipment. Here’s a summary of its core manufacturing processes:
- Fuselage structure design and casting process
Finite Element Analysis Optimization: The airframe structure is mechanically optimized through Finite Element Analysis (FEA) to ensure high rigidity and low deformation.
High-quality cast iron casting: It is made of high-strength cast iron material and annealed by all-cast iron to eliminate internal stress and improve mechanical stability and vibration resistance.
Gantry skeleton strengthening: The reinforced gantry structure is adopted to enhance the overall rigidity, which is suitable for high-speed and high-load processing.
- Five-axis drive system (cradle turntable)
DD Motor: The A/C axis is directly driven by a high-precision torque motor (A-axis swing ± 130°, C-axis infinite rotation), which avoids the backlash problem of traditional gear transmission and improves dynamic response and positioning accuracy.
High rigidity bearing support: The five-axis turntable adopts precision bearings to ensure stable operation under high loads (torque 120/240 N·m for A-axis and 45/135 N·m for C-axis).
- High-precision motion system
THK Lead Screws & Rails:
The X/Y/Z three axes are made of Japanese THK brand ball screws (lead 12mm), and the tail end is pre-pulled to reduce the impact of thermal deformation on accuracy (optional closed-loop control of grating scale).
The guide rail adopts 45# high rigidity roller guide rail, which has strong wear resistance and long life.
Servo drive system:
The X/Y/Z axis motors have a power of 3.9 kW, 3.9 kW and 5.9 kW respectively, ensuring high-speed (30m/min) and high-acceleration movements.
- Spindle system
High-speed motor spindle (12,000 rpm):
High-precision angular contact bearings are used to optimize the shafting arrangement to ensure low vibration and high rigidity.
Circulating cooling system: The spindle has an integrated cooling channel, with an external water cooler, which can quickly dissipate heat, reduce thermal deformation, and improve processing stability.
BT40 taper spindle, suitable for high-precision cutting, rated power 7.5/11kW, torque 32N·m (S1).
- Tool magazine and tool change system
Taiwan brand 24 knife arm type tool magazine:
The tool change time is only 2 seconds, and the maximum tool length is 250mm and the weight is 8kg, which meets the needs of efficient machining.
The high-precision positioning mechanism is used to ensure the accuracy and reliability of tool change.
- Lubrication and protection system
Taiwan brand automatic lubrication system: regular and quantitative lubrication of guide rails and lead screws to reduce wear and prolong service life.
Fully enclosed protective cover:
The three axes are equipped with stainless steel guards to prevent the ingress of iron filings and coolant, improving the cleanliness and life of the equipment.
Workbench slope flushing + centralized chip removal, optimize the processing environment, and reduce the need for manual cleaning.
- CNC system and electrical control
SYNTEC 220MA-5 CNC System (Taiwan Brand):
The 15-inch color touch screen supports five-axis linkage and four-axis semi-machining, and has high-precision interpolation function.
Combined with Schneider electrical components (Sino-French joint venture), it ensures stable power supply and anti-interference capability.
- Assemble and debug the whole machine
Precision assembly process:
Key components (such as lead screws, guide rails, spindles) are detected by laser interferometer + ballbar to ensure motion accuracy.
X/Y/Z axis positioning accuracy 0.005mm, repeatability positioning accuracy 0.003mm; A/C axis accuracy ±8 seconds, repeatability ±6 seconds.
Strict factory test:
Perform dynamic cutting tests to verify machining stability and ensure that the equipment achieves nominal accuracy.
- Environmental adaptability and installation requirements
Temperature control: The working environment temperature is 5~40°C, and it is recommended to install air conditioning to ensure accuracy.
Anti-vibration design: It is required to be far away from vibration sources (such as stamping machines, air compressors), and the height difference of the foundation is ≤ 10mm.
Dustproof and moisture-proof: The ambient humidity is ≤ 80% to avoid corrosive gases and dust.
