Product overview
This production line utilizes intelligent manufacturing and flexible changeover technology, capable of producing 66 different product variants. It supports rapid model changeovers (single-station die change time ≤30 minutes) to meet small-batch customization demands. The hybrid welding process combines robotic and manual welding to strictly comply with Cummins welding standards (CES-MANF-13). The integrated smart material handling system features: manual loading/unloading for small parts, robotic handling for large welded components, and manual operations assisted by balancer hoists for critical processes (leak testing, inspection, etc.), ensuring both efficiency and precision.

Product overview
Honing is a method of precision machining of holes or other machined surfaces using an oilstone (also known as a honing bar), and is a special form of grinding.
During honing, the oilstone is installed on the honing head, and the expanding mechanism expands the oilstone radially to press it against the surface of the workpiece. The honing head rotates under the drive of the machine tool spindle and performs reciprocating linear motion, or the workpiece performs reciprocating linear motion, to achieve honing processing of the workpiece.
Rolling is a method that utilizes the cold plasticity characteristics of metals at room temperature to apply pressure to the surface of the workpiece through rolling tools, causing plastic flow of the metal on the surface of the workpiece and achieving the purpose of finishing.
When rolling, rolling tools (such as ball bearings, cylindrical rollers, conical rollers, etc.) roll on the surface of the workpiece, applying pressure to the surface of the workpiece, causing plastic deformation of the metal on the surface of the workpiece, filling in the small bumps and depressions on the surface, and improving the surface smoothness.

Main features of machine tools
1. The machine layout adopts a single-sided movement mode of the guide wheel frame, and the feed guide rail adopts a double V-shaped rolling rigid guide rail (GCR15). The feed mechanism is driven by servo electric drive, achieving sensitive displacement, feed and compensation movements of the guide wheel frame, accurate positioning, long service life, and good system rigidity;
2. The linear speed of the grinding wheel is 45m/s, which has strong cutting ability, low grinding wheel wear rate, and good grinding surface quality. Compared with the linear speed of the 35m/s grinding wheel, the cutting surface ability and the service life of the grinding wheel can be improved by 20% to 30%;
3. The grinding wheel and guide wheel shaft both adopt a suspended structure, making it convenient to replace the grinding wheel and guide wheel;
4. The adjustment of the guide wheel adopts AC variable frequency infinite adjustment;
5. The operation adopts a display screen human-machine dialogue, with an automatic cutting in grinding program, and the feed rate, speed, and time can be adjusted;
6. Yonghua can enhance performance by selecting cutting mechanisms, long workpiece grinding brackets, magnetic separators for cooling systems, and other components through special ordering methods.
