(2) Industry Application Scenarios

- General Machinery Industry: Specifically designed and optimized for machining small crankshafts, a key component widely used in general mechanical equipment. With a high spindle speed of 5000 RPM, the XL & XL2-series CNC lathes realize high-speed precision cutting of 45# carbon steel, achieving an excellent surface roughness of Ra ≤ 0.8 μm. This advanced performance enables the "turning instead of grinding" process, effectively reducing the subsequent polishing procedures, lowering labor costs, and improving the overall production efficiency while ensuring stable machining quality.

- Home Appliance Industry: Focused on the precision machining of crankshafts and core rotating components for home appliances, including washing machine motor shafts, air conditioner compressors, and refrigerator compressor crankshafts. Boasting a high production efficiency of 120 pieces per hour, the series perfectly meets the large-scale, million-unit production capacity requirements of leading domestic home appliance brands such as Midea, providing reliable and high-quality machining support for the mass production of home appliances.

(3) Description of Machined Part Examples

- Home Appliance Motor Shaft: A critical core component for household washing machine motors, with a total length of 150 mm and a maximum diameter of Φ35 mm. The rotor position of the motor shaft adopts a strict tolerance standard of h6 to ensure precise matching with the motor rotor and stable operation. The part is made of 45# carbon steel (40Cr) and undergoes a black oxide surface treatment, which enhances its corrosion resistance and wear resistance, extending the service life of the motor shaft. Machined by the XL2-8D model of the XL2 series, the motor shaft achieves exceptional machining accuracy: the circular runout at the mounting position is strictly controlled within ≤ 0.005 mm, ensuring smooth rotation of the motor, and the motor efficiency is guaranteed to be ≥ 85%, meeting the energy-saving and high-efficiency requirements of modern home appliances.

(4) Domestic Customer Cases

- Electrical Machinery Sector: Guangdong ** Electric Motor Co., Ltd., a wholly-owned subsidiary of Midea Group (a global leading home appliance brand), has deployed 22 sets of XL2-8D CNC lathes for the mass production of high-precision motor shafts. These machines operate stably and efficiently, fully meeting the company’s annual production demand for 1 million washing machines, and laying a solid foundation for the stable supply of core components for Midea’s washing machine production line.

- Home Appliance Sector: Guangdong ** New Electric Co., Ltd., a key enterprise engaged in the production of home appliance core components in China, purchased 81 sets of XL2-8M CNC lathes specifically for motor shaft production. With a high production efficiency of 120 pieces per hour, the production line formed by these machines can stably meet the company’s annual demand for 6 million home appliances. The motor shafts machined by the XL2-8M are of excellent quality and stable performance, and are widely used in various home appliances, with part of the products exported to Southeast Asia and other overseas markets, winning recognition from international customers.
