Vertical Cylindrical Battery Grooving Machine

Product Overview

This vertical cylindrical battery grooving machine provides automated, high-precision circumferential grooving for cylindrical battery steel casings and supercapacitor aluminum housings. By pre-forming a uniform, mechanically sound indentation near the opening of the cylindrical can, the equipment establishes an exact seat for the internal gasket and cap assembly prior to final crimping. Its vertical orientation keeps the internal core stack and insulating components firmly seated throughout rotation, eliminating the cell misalignment and internal short-circuiting risks commonly associated with horizontal loading setups.

Engineered specifically to support both pilot-scale battery manufacturing and cutting-edge electrochemical research, this system accommodates a broad array of cell chemistries and casing form factors. From standard commercial sizes to custom large-format cylindrical cells such as 32700 and 4680 configurations, the unit provides consistent mechanical deformation across lithium-ion, sodium-ion, and supercapacitor product lines. Its compact benchtop footprint allows seamless integration into cleanrooms, dry rooms, and laboratory pilot environments.

Constructed with high-grade industrial components and a durable drive assembly, this unit delivers exceptional repeatable accuracy under continuous processing conditions. The intuitive PLC touchscreen interface provides researchers and production engineers with granular control over machine parameters, ensuring tight dimensional tolerances, reduced scrap rates, and streamlined transitions between varying cell diameters and manufacturing recipes.

Key Features

• Vertical Processing Architecture: The upright workpiece orientation utilizes gravity to stabilize the internal jelly roll, current collectors, and insulating washers, preventing internal component shifting or spacer displacement during high-speed rotation.
• Micrometer-Level Dimensional Precision: High-rigidity grooving assemblies maintain tight machining tolerances of ±0.1 mm, producing uniform channel geometry essential for leak-proof hermetic seals.
• Adjustable Grooving Depth: Continuous depth adjustment from 1.2 mm to 2.0 mm accommodates varying casing thicknesses and structural crimp requirements across different cell designs.
• Tooling-Defined Grooving Width: Channel widths ranging from 1.1 mm to 1.5 mm are determined by precision-ground rotary cutter tooling, ensuring sharp profile definitions and consistent stress distribution.
• Extended Tooling Service Life: Ultra-hardened alloy grooving blades deliver an operational lifespan exceeding 1,000,000 cycles, significantly lowering tooling replacement frequency and production downtime.
• Integrated PLC Touchscreen Control: An intuitive digital interface allows operators to easily configure cycle parameters, monitor system diagnostics, and achieve repeatable batch-to-batch consistency.
• Semi-Automated High Throughput: Capable of processing up to 400 units per hour (EA/H), balancing operational throughput with the strict quality control required for pilot manufacturing lines.
• Broad Form Factor Adaptability: Accommodates standard cylindrical cans and aluminum capacitor shells up to Φ30 mm, with modular tooling packages available for large-format cylindrical cells like 32700 and 4680.
• Pneumatic Clamping Stability: Driven by an industrial 0.5 to 0.7 MPa compressed air supply, the pneumatic chuck provides uniform radial clamping force without deforming thin-walled battery housings.
• Compact Benchtop Footprint: Measuring just L420 x W370 x H550 mm, the space-efficient design allows convenient installation inside standard pilot benches or controlled environment enclosures.
