Recently, Nanjing Chunxin Automation Equipment Co., Ltd. acquired a new precision machining tool: a high-precision CNC cylindrical grinding machine specifically designed for ball screws. The machine has been successfully installed, commissioned, and put into operation. The introduction of this equipment not only fills a technological gap in the factory's high-end ball screw precision grinding capabilities but also marks a significant leap forward in the factory's precision transmission component processing capabilities, laying a solid hardware foundation for its deep cultivation of the high-end manufacturing market.
The newly purchased ball screw cylindrical grinding machine incorporates advanced technologies in the current CNC grinding field, possessing core advantages such as high precision, high rigidity, high efficiency, and high adaptability. The equipment stably controls dimensional tolerances within the micron range, achieving grinding accuracy up to P3 level, fully complying with international precision standards.
Regarding core component configuration, the equipment's grinding wheel spindle adopts a rear-mounted motor hydrostatic bearing structure, offering high rotational accuracy and strong rigidity. Combined with a maximum grinding wheel linear speed of 45 m/s, this effectively improves the surface finish of the ball screw. Meanwhile, the equipment is equipped with an intelligent grinding wheel dressing system, which automatically dresses and compensates for complex grinding wheel profiles using diamond rollers. Combined with a high-precision ball screw feed mechanism driven by a servo motor, this significantly reduces human intervention errors, ensuring consistency and stability in mass production.
"The deployment of this equipment is an important step for the factory in implementing the concept of 'technology empowering production'," said the factory's production manager. It can easily handle the processing needs of ball screws of different specifications and pitches, with a maximum grindable thread length of 4 meters, providing ample support for customized customer needs.
Ball screws, as core components of precision transmission, are widely used in high-end fields such as machine tools, automation equipment, and aerospace. Their machining accuracy directly determines the operational stability and precision of the end product.
The factory will organize its technical team to conduct in-depth equipment operation and maintenance and skills training, fully explore the equipment's performance potential, empower product upgrades with precise machining, continuously deepen its expertise in the precision manufacturing field, and contribute to the high-quality development of the industry with higher-quality products and services.
