With the increasing popularity of electric vehicles, the issue of quiet and smooth operation has become increasingly important, which has also increased the demand and application of ultra precision machining technology. The overall trend of electric vehicles will be a significant reduction in the number of metal parts, but when machining automotive parts, the requirements for higher quality surface finish and tolerances will increase with the increase in part complexity. Enterprises supplying original equipment manufacturers in the automotive industry need to diversify their customer base and seek other industries to ensure that production capacity does not suffer catastrophic losses. The power battery, chassis, casing, touch screen, motor, and motor of new energy vehicles all involve precision machining. The construction of new energy vehicle production lines has generated a large demand for precision machining centers.

    We have noticed that the demand for ultra precision machining technology has not slowed down with the trend of electric vehicle development, but rather has increased, "explained Mr. Christian Feuchter from the company's technology sales department, For traditional internal combustion engine parts, the demand for ultra precision machining is indeed decreasing, but the demand for machining electric vehicle parts, especially gearbox parts and rotating shafts, is increasing. At the same time, the demand for ultra precision machining is also constantly increasing. In addition to automotive powertrain components, the demand for ultra precision machining is also increasing for other types of driving devices, such as steering gear racks and nuts. Automotive component suppliers are committed to producing related parts such as transmission shafts for electric vehicles, confirming this trend: ultra precision machining is an increasingly needed manufacturing process in the field of electric vehicles, with the aim of improving the load-bearing capacity and surface accuracy of workpieces.

Original equipment manufacturers and their suppliers are changing the components they manufacture and the way they manufacture them, as the driving experience and market demand for profit are disrupting. We have listed some requirements for processing automotive parts in the electric vehicle industry as follows.

Is there a precision machining method that meets all the above requirements? The answer is yes, precision grinding is one of the most representative technical routes.

Unlike internal combustion engines, the operating noise of electric drive devices is inherently very low, which makes the whistling noise emitted by the bearings particularly noticeable. These noises are mainly caused by the machining ripples on the surface of the shaft neck after turning and grinding of the transmission shaft, which are inevitable during the turning and grinding processes. When the transmission components emit this noise, the corresponding friction and energy loss will also increase. Therefore, automotive component manufacturers are continuously improving their requirements for product dimensional accuracy and surface polishing quality. After all, people hope that vehicles can drive quietly on the streets instead of making strange noises. Based on this background, ultra precision machining is becoming a key technology in the production chain of electric drive system components, as only ultra precision machining can eliminate machining ripples on the surface of the journal.

The workpiece is fed through the top hatch of the equipment through a truss robotic arm, and after finishing the ultra precision machining, the workpiece is fed into the subsequent automatic transmission chain system. Mr. Christian Feuchter confidently stated, "This highly flexible equipment platform, with modular design, is a highly cost-effective ultra precision machining solution. This series of equipment, like other high-precision equipment, is manufactured to the same high-quality standards. These ultra precision processed products are highly favored by customers in the market.
