With the idea of "Continuous Improving", NYY constantly imported advanced manufacturing facilities and enhances the machining process to get higher quality precision.

High precision surface grinding equipment and proper frock clamp will get greater gear datum precision. Particularly in vertical CNC inner grinding equipment, with one set-up, grinding the plane and bore in one process ensures the gear orientation datum accuracy.

Profile gear grinding device can make the high precision gear with all types of profile modification, lead modification.



The RAPID 2500 cylindrical gear grinding machine is the expert for large, heavy work-pieces as much as 2,500 mm in diameter and weighing approximately 25 tons. These giants integrate maximum dimensions with absolute accuracy, speed, and flexibility: Topologically correct (a kind of modification compensation) results with reduced grinding times and an optional internal grinding device form the basis for affordable, reliable cylindrical gear production on this scale. Together with the cutting equipment, RAPID equipment in the cylindrical gear technology department provides an ideal system for the cylindrical gear production process.

Wind power plants contain a variety of toothed gear drives for different jobs: semi-rotary drives for adjusting the machine housing, drives for adjusting the rotor blades, and gearboxes for adjusting the rotor speed to the generator speed. To manufacture this variety of toothed gears with optimum efficiency, the market demands devices that can get the most out of the capacity that contemporary carbide tools offer.

Just efficiently cut cylindrical gears are used in wind power. This is because just optimal gear geometry offers optimal transmission of force for extremely efficient wind power plants while guaranteeing exceptionally quiet running behavior. High-precision gearing quality increases the life span of individual gearbox parts, which considerably reduces maintenance costs. Precision measuring centers from Klingelnberg make sure that the optimum gear geometry is kept with a high degree of precision, and that suitable quality accreditation is offered.
