In the Yangtze River Delta, it only takes 4 hours to produce a new energy vehicle. Driven by an increasingly complete industrial system, China's production and sales of new energy vehicles have ranked first in the world for eight consecutive years.
In the first half of this year, the development momentum of China's new energy vehicle industry is good. The three sets of data of production and sales, market share and inventory all hit record highs. New energy vehicles have become a shining new business card made in China.
These achievements are inseparable from the support of the production line, and efficient production and processing naturally cannot do without the cooperation of machine tools, cutting tools and clamping technology. Today, the editor will introduce to you the new energy vehicle processing solutions from SCHUNK, Walter and EMAG.

Cell handling and assembly solutions
In recent years, the rapid development of power batteries has brought new opportunities and challenges to the automotive industry, helping new energy vehicles to run out of "acceleration". SCHUNK can provide battery handling services in every link from battery production to final assembly to the body. and assembly support.
Square cell grabbing
Use the JGP series pneumatic two-finger translational manipulator with spring self-locking function to grab square batteries. JGP universal two-finger translation manipulator adopts T-slot guide rail, high-strength aluminum alloy material, compact structure and light weight. Optional quick claw change system can adapt to different sizes of batteries.

EMAG VL6 inverted single-spindle high-precision lathe
As a typical product of EMAG's inverted turning center, the VL6 machine tool is suitable for combined turning, milling and drilling of disc parts with a diameter of <300mm, including the main reduction gear and intermediate shaft gear in the drive motor of new energy vehicles.
Difficulties in processing
High precision dimensional and geometric tolerance requirements
Efficient parts processing cycle time
processing method
Relying on excellent machine rigidity, unique inverted structure design, and high stability, VL6 can stably achieve gear inner diameter within 120±0.01mm and inner diameter cylindricity within 0.008mm.
Each machine tool of the VL series is a complete production unit, with a unique inverted spindle structure, the spindle is not only used for processing workpieces, but also for external automatic loading and unloading, which saves expenses, floor space and unnecessary External automation equipment, high efficiency and high economy.
