The explosive growth in production and sales of new-energy vehicles will lead to an increase in demand for new-energy lithium-ion battery boxes. Due to its cost reduction and weight reduction characteristics, the use of composite materials has become more and more wide, the composite material battery pack housing adopts micro-foam technology, greatly reduces the part density, can easily achieve the goal of enclosure weight reduction, and at the same time, the key features With the technology can meet the requirements of airtightness test and water settling test. At the same time, it has the characteristics of high strength and high toughness, ensuring sufficient mechanical performance for the enclosure.
The new energy battery outer shell processing mainly USES CNC processing, which has the advantages of stable product quality, high precision and high production efficiency. Milling is the most widely used method in composite machining. Battery housing machining, for example, composite parts with large size and thick outer walls (especially jet engine housings) require a large amount of side milling and fay. Smiling is required, and hole processing usually involves milling. Huiwen zhizao is a machining factory with more than 10 years CNC machining experience, with complete equipment, CNC digital control vehicle/milling/grinding/drilling/machining, we are welcome to offer by phone with our partners who have demand for machining parts .
Due to the particularities of the composite materials, the processing of the new energy battery case needs to pay attention to the following points.
Tool selection: since composite materials are generally strong and hard, it is necessary to select the appropriate tool material and tool geometry to ensure the efficiency and quality of the machining.
Cutting parameters: for the characteristics of the composite material, it is necessary to set cutting parameters such as cutting speed, feed speed, cutting depth reasonably to avoid overheating and tool loss.
3. Tool path planning: battery case since the structure of the machining composite is complex and generally requires multiple cutting, it is necessary to plan the toolpath reasonably to ensure the accuracy and consistency of the machining.
4. Precision control: because the machining accuracy of composite materials is high, it is necessary to ensure the stability and rigidity of the machine tool and the precision que of the control system in order to achieve precise machining.
Overall, CNC machining of composite materials must be adjusted and optimized based on the specific material properties and processing requirements. Before processing, we consult our professional machining engineers or experts in the relevant field to ensure the accuracy and quality of the processing process.
