The YK72/YK73 series adopt topology optimization for high-rigidity integral cast vertical structure design, balancing exceptional rigidity and stable load-bearing capacity to support precision grinding of cylindrical gears, helical gears, and other gear types (worm gear grinding for YK72, forming wheel grinding for YK73).
The YK72/YK73 series are equipped with high-precision high-torque motorized spindles, tailored to match their gear grinding requirements for various moduli, with spindle speeds optimized for efficient gear finishing and stable high-precision cutting performance.
The YK72/YK73 series feature customized multi-axis CNC servo drive solutions (including software-based electronic gearbox for YK72), adapting to the efficiency needs of high-precision gear grinding and batch production scenarios.
Relying on robust integral cast structures, precision guide systems, excellent vibration damping, and thermal stability, the YK72/YK73 series maintain consistent stability and DIN-level precision (high-precision grinding accuracy) in long-term operation.
The YK72/YK73 series are fitted with dedicated lubrication and cooling systems (comprehensive cooling for YK72), supporting continuous batch machining by effectively controlling equipment and spindle thermal deformation.
The YK72/YK73 series use mainstream CNC systems (FANUC/Siemens/Heidenhain for YK72, Siemens 840Dsl for YK73), ensuring precise multi-axis linkage, full closed-loop control, and reliable performance in high-precision gear grinding.
The YK72/YK73 series cover a wide range of gear machining needs, with gear diameter range from 12mm to 4000mm, modulus range from 0.5mm to 40mm, and spiral angle up to ±45°, meeting processing requirements for gears in automotive, aerospace, wind power, and heavy machinery industries.
The YK72/YK73 series are configured with high-precision grinding wheel holders and automatic dressing systems, enabling seamless gear grinding with consistent accuracy (worm wheel grinding for YK72, forming wheel grinding for YK73).
The YK72/YK73 series are equipped with high-efficiency chip conveyors, promptly handling gear grinding chips and debris to keep the precision grinding process smooth.
The YK72/YK73 series’ cutting fluid systems deliver targeted precise supply, aiding cooling, chip removal, and tool life extension during high-precision gear grinding, with optional electrostatic mist extraction for YK73.
