1. Project background and challenges

ವಸ್ತು ಗುಣಲಕ್ಷಣಗಳು:Bakelite (phenolic resin) is a thermosetting plastic with high insulation and strong heat resistance. However, due to 

its high brittlenessand poor thermal conductivity, it is prone to surface burns, edge cracking and unstable dimensional accuracy during processing.

ಸಂಸ್ಕರಣಾ ಅವಶ್ಯಕತೆಗಳು: 

A new energy electric vehicle manufacturer needs to batch process bakelite sealing rings with an outer diameter of 20mm and a thickness of 10mm. The requirements are that the parallelism of the two end surfaces should be ≤0.005mm, the flatness should be ≤0.1mm, and the surface roughness Ra should be ≤0.4μm.

2. Equipment selection and configuration

ಡಬಲ್ ಮೇಲ್ಮೈ ಗ್ರೈಂಡರ್ ಆಯ್ಕೆ:

ಲಂಬ ಡಿಸ್ಕ್ ಪ್ರಕಾರ ಡಬಲ್ ಡಿಸ್ಕ್ ಗ್ರೈಂಡರ್: vertical structure, strong grinding wheel rigidity, suitable for high-precision thin-sheet workpiece 

ಸಂಸ್ಕರಣೆ.

ಪ್ರಮುಖ ನಿಯತಾಂಕಗಳು:

Grinding wheel speed:150-950 rpm (reduce the risk of thermal damage)

Workpiece speed:1-10Rmp (optimize the speed ratio to improve the uniformity of material removal)

ಶೀತಲೀಕರಣ ವ್ಯವಸ್ಥೆ:high-pressure atomized coolant to reduce thermal deformation of bakelite

Automation integration: can be equipped with automatic loading and unloading devices to achieve continuous feeding and finished 

product sorting, reduce manual intervention and improve efficiency

3. Processing results

ಸಮಾನಾಂತರತೆ:0.004mm (better than customer requirements)

ಮೇಲ್ಮೈ ಬಿರುಸು:ರಾ 0.35μm

4. Industry application promotion value

This case verifies the potential of double-end face grinders in non-metallic material processing, especially for:

ಎಲೆಕ್ಟ್ರಾನಿಕ್ಸ್ ಉದ್ಯಮ:high-precision components such as insulating gaskets and connector housings;

ಆಟೋಮೋಟಿವ್ ಉದ್ಯಮ:heat-resistant sealing rings and sensor components.

Technical extension:By adjusting the grinding wheel parameters and cooling solutions, it can be adapted to the processing of hard and brittle materials such as ceramics and composite materials.

The application of bakelite sealing rings in electric vehicles is mainly reflected in battery seals. Battery seals play a key role in the power battery system of electric vehicles, ensuring the stable operation of the system under various environmental conditions.
