Cylindrical Battery Grooving Machine Automatic and Manual Benchtop Cylindrical Cell Groover

Product Overview

This benchtop cylindrical battery grooving machine delivers micron-level mechanical precision for pre-crimping cylindrical battery casings and supercapacitor shells. Engineered to form uniform circumferential indentations on metal canisters, this system establishes the vital mechanical seat required for O-rings, gaskets, and cap assemblies prior to final sealing. By combining pneumatic actuation with hardened forming tooling, the equipment ensures leak-tight integrity and repeatable structural geometry across all cell formats.

Designed specifically for electrochemical laboratories, university cleanrooms, and small-batch pilot lines, the equipment bridges the gap between manual prototyping and high-throughput automation. It accommodates a wide spectrum of cylindrical casing dimensions—including standard 18650, 21700, 26650, and 32650 formats, as well as customized cylindrical enclosures. Operators can seamlessly transition between manual setup jogging and rapid automatic cycling to support diverse research requirements and production quotas.

Built on a rigid, vibration-dampened frame constructed from premium chrome steel, this unit withstands corrosive electrolyte environments and continuous mechanical cycling. Its streamlined footprint allows convenient pass-through and operation inside inert gas glovebox workstations. With stepless spindle speed modulation, independent depth and height micrometer adjustments, and integrated cycle timing, this system provides unmatched consistency, operator safety, and process reliability for demanding energy storage development programs.

Key Features

• Micrometer-Accurate Depth and Height Adjustments: Features dedicated mechanical end-stop micro-adjusters on both the clamping and grooving pneumatic cylinders, providing an axial blade adjustment range of 0 to 20 mm and a radial depth adjustment range of 0 to 10 mm with ±0.1 mm repeatability.
• Precision-Ground Tooling Dies: Incorporates ultra-hardened, precision-machined grooving blades and customized internal guide mandrels (1.1 mm to 1.6 mm groove width profiles) that prevent casing deformation, wrinkling, or sidewall thinning during high-speed rotation.
• Dual Manual and Automatic Cycling Modes: Offers a versatile control architecture enabling manual jog mode for rapid prototype alignment, tooling calibration, and trial runs, alongside a single-touch foot-pedal automatic mode for streamlined production cycles.
• Stepless Spindle Speed Control: Driven by an efficient 140W motor capable of stepless spindle speed regulation up to ~300 r/s, enabling optimized surface speeds tailored to varying casing alloys, wall thicknesses, and ductility properties.
• Programmable Grooving Dwell Timer: Integrates a digital cycle timer within the control panel to govern pneumatic feed dwell duration, ensuring consistent deformation across steel, nickel-plated, and aluminum canisters.
• Glovebox-Ready Compact Architecture: Optimized envelope dimensions and sealed pneumatic conduits allow straightforward installation into inert argon or nitrogen gloveboxes for moisture-sensitive next-generation chemistries.
• Industrial Chrome Steel Construction: All critical structural plates and guide shafts are fabricated from high-tensile chrome steel and treated with eco-friendly electroplating and specialized anti-corrosion spray coatings that permanently eliminate rust.
• Quick-Change Guide Socket Mechanism: Features a smooth-sliding spring-loaded tailstock guide assembly that facilitates rapid one-handed canister insertion, concentric alignment, and swift post-process extraction without scratching exterior surfaces.
