- Structural design and materials
Integral bridge gantry structure: adopts a high-rigidity integral gantry design, the bed, beam, slide, headstock and other core components are made of high-strength cast iron (resin sand casting process), and the structure is optimized through finite element analysis to ensure static/dynamic rigidity and long-term thermal stability.
Heat treatment process: All castings undergo a complete heat treatment process to eliminate residual stress and arrange stiffeners to improve stability.
- locomotor system
Linear guide and ball screw:
The X/Y/Z axis adopts 45# roller linear guide, with high rigidity and low friction, and a rapid displacement of up to 36 m/min.
Each axis is directly driven by AC servo motor ball screw (model 4012), fully closed-loop control (optional grating ruler), positioning accuracy ± 0.006mm.
Rotary axis (A/C axis):
Direct drive (DD torque motor), no transmission backlash, A-axis swing range ± 120°, C-axis 360° continuous rotation.
It comes standard with a grating ruler, with a positioning accuracy of ± 5 arcseconds, and oil-cooled heat dissipation to ensure thermal stability.
- Spindle system
High-speed electric spindle: HSK-A63 tool holder, maximum speed 20,000 RPM, power 30kW (S1 working condition), torque 69.4Nm, support rigid tapping and spindle orientation. Built-in motor encoder for stepless speed regulation and precise control.
- Knife magazine and tool changer
24-position chain servo tool magazine: supports automatic tool change (tool change time 1.8 seconds), maximum tool diameter φ75mm, length 300mm, weight ≤8kg.
- Lubrication and cooling
Centralized lubrication system: Quantitative oil injection into the guide rail and lead screw for extended life.
Oil/water cooling systems: The spindle and electrical cabinet are equipped with independent cooling units (e.g. Leide brand) to ensure stability in high-temperature conditions.
- Protection and chip evacuation
Fully enclosed shield: prevents chips from eroding the guide rail and lead screw.
Chain plate type chip conveyor: inclined protective wall design, chips automatically slide into the chip removal groove, economical and practical.
- CNC System (SYNTEC)
It supports five-axis linkage (RTCP function), NURBS interpolation, polar programming, and subprogram nesting (level 4 and above).
Features tool life monitoring, error compensation (clearance/pitch), graphical simulation, and anti-collision protection.
- Testing and calibration
