New Models Offer High Precision and Efficiency

Kyoto, Japan – NIDEC Machine Tool Corporation announced the launch of the ZFA Series, a new line of high-precision gear grinders designed to meet global demand for advanced gear machining. The ZFA160 and ZFA260 models offer exceptional performance and efficiency for a wide range of gear sizes.

Designed for high-speed and high-precision finishing of gears, the ZFA Series features a twin-table structure and high-speed rotary performance, resulting in a significantly reduced non-machining time compared to previous models. The ZFA160 and ZFA260 also incorporate advanced features to ensure fast, stable and accurate machining, including stiffer work-table structures, grinding spindles, and dressing units.

The ZFA Series is ideal for machining gears for electric vehicles and robots, offering features like simultaneous double-tooth flank bias adjustment and low-noise machining. Additionally, the models are designed with environmental sustainability in mind, featuring a circular, filter fabric coolant tank that reduces waste generation.

As the demand for high-precision gears continues to grow, NIDEC Machine Tool is committed to providing innovative solutions that meet the evolving needs of the global market. The ZFA Series offers a combination of precision, efficiency, and sustainability, making it a valuable asset for manufacturers worldwide.

*1. By installing two work-accommodating tables onto a machine, one can set up machining on one side while machining is underway on the other side.

*2. A component or material whose natural rock, etc. has been solidified with resin. This material has a low thermal conductivity, is hard to be affected by temperature change, and has a high vibration damping. In addition, unlike cast metals, there is no manufacturing process that discharges a large amount of CO₂.

*3. An index that indirectly represents the precision of a gear’s pitch circle. “O.B.D” stands for “over ball diameter.”

*4. Module: A value that represents the size of a gear’s teeth (i.e., the pitch circle’s diameter (mm) divided by the number of teeth).
