Automatic Cylindrical Battery Grooving Machine for 18650 21700 and 26650 Steel Shells

Product Overview

This automatic cylindrical battery grooving machine is designed to form uniform grooves in cylindrical steel battery shells through automated feeding, processing, and unloading. It combines adjustable groove dimensions, stable forming accuracy, and convenient touch-screen operation in a compact production unit. The integrated process reduces manual handling while supporting repeatable shell preparation for downstream battery assembly.

The equipment is suitable for cylindrical battery research, pilot production, and manufacturing environments working with multiple shell formats. Standard tooling supports the 18650 series, while interchangeable tooling enables processing of other cylindrical battery sizes such as 21700 and 26650. Its compact footprint and straightforward control interface make it practical for laboratories, production workshops, and flexible cell fabrication lines.

Built for consistent daily operation, the unit uses PLC control, a touch interface, and durable grooving tooling rated for more than three million operations. Adjustable process dimensions, a precision of ±0.1 mm, and a production rate of 6 PCS/min provide a balanced combination of repeatability, efficiency, and process control.

Key Features

• Automatic Feeding and Unloading: The system automatically transfers cylindrical steel shells into and out of the grooving station, reducing manual intervention and improving workflow efficiency.

• Adjustable Groove Depth: Groove depth can be set from 1.0 to 3.0 mm, allowing the equipment to accommodate different process requirements and cylindrical shell specifications.

• Stable Groove Dimensions: Groove width is determined by the cutting tool thickness, with a specified range of 1.1 to 1.5 mm. This supports controlled and repeatable forming results.

• High Processing Accuracy: The equipment provides a grooving accuracy of ±0.1 mm, helping maintain consistent shell geometry for subsequent battery assembly operations.

• Interchangeable Tooling: Replacing the forming die allows the unit to process various cylindrical battery formats. Standard tooling is supplied for the 18650 series, with tooling options available for other supported sizes.

• PLC and Touchscreen Control: A PLC-based control system and touch interface simplify parameter setting, machine operation, and adjustment of production conditions.

• Long Tooling Service Life: The grooving cutter has a stated service life of more than three million operations, helping reduce replacement frequency and support stable long-term use.

• Compact Industrial Design: Measuring 550 × 600 × 720 mm, the unit occupies limited floor space while providing an integrated automated grooving process. Its compact and refined structure is well suited to laboratory and workshop environments.

• Efficient Production Rate: A rated capacity of 6 PCS/min supports efficient shell processing for pilot lines and small-scale manufacturing without requiring a large production footprint.

Applications

Technical Specifications

The adjustable 1.0–3.0 mm groove depth provides process flexibility when different shell designs or assembly requirements are involved. Groove width is controlled by the installed cutter thickness within the specified 1.1–1.5 mm range. These adjustment capabilities allow operators to configure the forming process according to the selected cylindrical battery format and tooling arrangement.

The standard 18650-series die allows the equipment to be commissioned for a common cylindrical cell size. When production requirements change, the forming tooling can be replaced to support other formats, including 21700 and 26650 designs. This approach helps laboratories and pilot manufacturers use one compact platform across multiple development programs instead of dedicating separate machines to every shell size.

With a rated accuracy of ±0.1 mm, the unit is intended for applications where groove position and dimensional stability influence the consistency of downstream assembly. The automatic feed and discharge process also creates a more repeatable operating sequence than manual loading and unloading, helping reduce handling variation during continuous work.

The 6 PCS/min capacity provides a practical throughput level for battery research laboratories, pilot production, and small-batch manufacturing. The 0.2 kW power rating and AC220V/50Hz supply requirement simplify integration into standard electrical environments, while the required compressed air supply is 0.5–0.7 MPa. The 550 × 600 × 720 mm dimensions allow the machine to be installed where floor space is limited.

Why Choose This Product
