MSK-500-L Semi-Automatic Grooving Machine for 4680, 46120, and 50100 Cylindrical Cells
The MSK-500-L is engineered to facilitate the grooving process of cylindrical battery cells, specifically tailored for 50100 cases but adaptable to 4680 and 46120 sizes through modification. This semi-automatic machine enhances the preparation of cylindrical cells by creating precise grooves on the casing, which is a critical step before sealing and further battery assembly.
Grooving is performed with high accuracy, maintaining a depth range between 0.8 and 2.0 mm and a width adjustable from 0.9 to 1.5 mm, with a standard width of 1.2 mm. The machine ensures consistent groove quality with a tolerance of ±0.1 mm, supporting efficient and reliable battery cell manufacturing workflows.

Typical Applications
The MSK-500-L is used in battery manufacturing and research laboratories for preparing cylindrical battery cells by grooving their casings. This process is essential for ensuring proper sealing and assembly of cells such as 50100, 4680, and 46120 formats, commonly employed in energy storage and electric vehicle applications.
Configuration & Operating Notes
Different grooving die sets are required to accommodate various cylindrical cell sizes; these are not included by default and must be selected according to the cell type. After grooving, sealing the cell cap with a compatible sealing machine (e.g., MSK-510) is necessary to complete cell preparation.
The machine requires a stable compressed air supply exceeding 0.5 MPa. When using a gas cylinder instead of an air compressor, a two-stage pressure regulator must be installed to ensure safe operation within the specified pressure range.
