In this feature, we focus on a core phase of the brake disc manufacturing line—the third process involving the precision finish turning of the outer side using our signature LYV-500 single-column vertical lathe with an 8-position turret. By integrating innovative tool configurations with high-rigidity machine structures, Hengga Intelligent Equipment delivers superior performance that redefines standards in precision machining. Explore the video and article below to discover how our engineering expertise drives productivity forward.

In the manufacturing process of automotive braking system components, the finish machining of brake discs plays a critical role in determining the final quality and safety performance of the product. The LYV-500 brake disc vertical lathe, independently developed by Longkou Hengga Intelligent Equipment Co., Ltd., serves as the core processing equipment in the third operation of the brake disc production line, undertaking the precision turning of the outer face of brake discs. Featuring a single-column, single-tool-position structure equipped with an 8-station hydraulic turret, this machine delivers stable and high-precision cutting performance for brake disc outer face machining.

The bed and column of the LYV-500 brake disc CNC vertical lathe adopt a thermally-symmetrical box-type ribbed structure, which effectively minimizes thermal deformation caused by temperature fluctuations during prolonged operation, thereby maintaining consistent machining accuracy. Both the X-axis and Z-axis utilize a wide-span layout, paired with oversized imported high-rigidity linear guideways, ball screws, and heavy-duty enlarged roller sliders. This combination significantly enhances the machine's rigidity and positioning accuracy during cutting operations, ensuring stable performance even under continuous high-load cutting conditions.

The machine spindle is equipped with high-precision P4-class bearings arranged in a two-point support wide-span configuration, ensuring excellent rotational accuracy and rigidity during high-speed operation. The spindle is lubricated with imported high-grade grease in a fully enclosed system, requiring minimal maintenance and effectively reducing both maintenance costs and downtime. The X-axis and Y-axis are fitted with high-precision double-nut preloaded precision ball screws, combined with locked support seats at both ends. This design eliminates transmission backlash and pre-compensates for errors caused by temperature rise, further meeting the stringent positioning accuracy requirements of brake disc finish machining.

During actual processing, the LYV-500 brake disc CNC vertical lathe accomplishes rapid tool changes through its 8-station hydraulic turret. The turret features high reliability, fast tool changing, and precise positioning, making it well-suited for continuous multi-tool, multi-process operations in brake disc outer face finishing. The machine is equipped with a 12-inch 3-jaw hydraulic chuck that provides secure and stable clamping. Combined with the vertical spindle structure, the workpiece experiences uniform forces during machining, effectively ensuring the machining accuracy and surface quality of the brake disc outer face.

The LYV-500 brake disc CNC vertical lathe is suitable for rough and finish machining of various disc-type components, including automotive wheel hubs, brake drums, brake discs, engine end caps, flywheels, and flanges. With its compact footprint and excellent production efficiency, the machine enables one operator to manage multiple units simultaneously, saving factory floor space and reducing overall management costs. Whether used for small-batch, multi-variety production or integrated into automated production lines for high-volume manufacturing, the LYV-500 provides a reliable and efficient solution for automotive component manufacturers seeking to enhance both product quality and production efficiency.
