Cylindrical Capacitor Casing CNC Grooving and Pre Sealing Machine

Product Overview

This high-precision CNC grooving and pre-sealing system is engineered specifically for cylindrical supercapacitor housings, ultracapacitor shells, and large-format cylindrical battery cell casings. Utilizing synchronized servo-motor ball-screw feed mechanisms instead of conventional pneumatic actuation, this equipment delivers absolute feed distance control and linear stability. It eliminates mechanical rebound under load, ensuring uniform circumferential grooves and repeatable pre-sealing crimps essential for hermetic cell integrity.

Designed for both pilot-scale development and medium-to-high-volume industrial cell manufacturing, the system standardizes production on diameter 60-series cylindrical formats, with adaptable tooling architectures available for custom casing diameters. By integrating intelligent touchscreen parameter configuration with robust sleeve-type clamping fixtures, the machine maintains tight concentricity and dimensional stability across continuous high-throughput shifts.

Built for demanding industrial environments, the equipment combines a heavy structural frame, dual-stage velocity profiling, and fully enclosed smart safety protections. Its high equipment availability and long-life tooling ensure lower total cost of ownership, exceptional batch-to-batch consistency, and compliance with the stringent quality standards required in high-reliability energy storage production.

Key Features

• Precision Dual Servo-Screw Drive: Both grooving and sealing axes are driven by dedicated servo motors coupled with high-precision ball screws, delivering micron-level tool positioning, steady feed rates, and zero pneumatic bounce or rebound under heavy material resistance.
• Two-Stage Controlled Crimping Action: The sealing tool features an automated velocity transition, advancing at high speed toward the casing edge before shifting smoothly to a slow, controlled crimp, preventing material stress cracking and flange deformation.
• Concentric Sleeve-Type Collet Clamping: The specialized circular jacket fixture firmly locks cylindrical shells without radial distortion, maintaining high coaxial alignment to achieve uniform groove depth, superior out-of-roundness tolerances, and zero workpiece wobble during high-speed rotation.
• High-Precision Linear Guideway Assemblies: Tool carriages ride on rigid, preloaded linear guideway sets, eliminating backlash and structural deflection during continuous lateral grooving and downward sealing cycles.
• Digital Recipe Management via PLC & Touchscreen HMI: Operators can digitally configure, store, and recall grooving depths, sealing heights, and feed velocities directly from the graphical interface, drastically minimizing changeover downtime and manual setup errors.
• Long-Life Hardened Tooling: Roller grooving and sealing tooling are fabricated from premium wear-resistant tool steels, engineered to exceed an operational lifespan of 5,000,000 cycles under standard production conditions.
• Comprehensive Interlocked Safety Enclosure: A robust physical enclosure with intelligent safety interlocks fully isolates the rotating spindle and automated tooling during operation, protecting operators while maintaining full process visibility.
• High Operational Efficiency: Designed for robust manufacturing lines, this system delivers an operational uptime rating of 98% with an index cycle rate exceeding 3 parts per minute for consistent production output.

Why Choose This Product

• Elimination of Pneumatic Inconsistencies: Unlike conventional pneumatic grooving machines that suffer from pressure drops and variable tool pushback against hardened metal casings, this system utilizes pure servo-driven ball screws for unyielding, micrometer-precise feed depth.
• Superior Hermetic Integrity: By combining concentric sleeve clamping with a two-stage slow-crimp profile, the machine achieves roundness and uniform wall distribution, eliminating micro-fractures in the casing lip and ensuring high seal reliability.
• Extensive Tooling Longevity: Industrial-grade tooling engineered to withstand 5,000,000 cycles drastically reduces recurring consumable costs and minimizes machine downtime required for tooling replacements.
• Seamless Production Integration: Built-in PLC sequencing and digital parameter storage allow this system to function effectively as a standalone workstation or integrate smoothly into wider automated cell assembly workflows.
• Robust Heavy-Duty Build Quality: Weighing a solid 800 kg, the rigid machine frame absorbs rotational vibration during spindle operation, guaranteeing consistent tolerances across millions of cycles.
