Precision Slitting Head for Battery Electrode Slitting Machines

Product Specifications

Technical details and manufacturing context for Precision Slitting Head

Definition

The Precision Slitting Head is a core cutting assembly within a battery electrode slitting machine. It performs high-accuracy longitudinal slitting of coated electrode foils (anode or cathode) into multiple, uniform strips of precise width, which are essential for the subsequent winding process in battery cell assembly. Its precision directly impacts electrode quality, material yield, and final battery performance. The head typically houses one or more sets of precision-ground circular slitting knives (or razor blades) mounted on parallel arbors. The electrode web passes between an upper and lower knife set, where the knives overlap to create a shearing action. The cutting width is determined by spacers between the knives. The head may be driven or idle, with precise alignment and minimal runout being critical for clean, burr-free cuts and to prevent foil wrinkling or tearing. The unit is available with a cutting width range of 50–600 mm, slitting speed of 30–120 m/min, and cutting tolerance of ±0.05 mm. Blade diameter ranges from 150–300 mm, with blade material options of HSS or WC (DIN 1.3343). Motor power is 2.2–7.5 kW (IEC 60034), supply voltage 380–480 V AC (IEC 60038), operating pressure 1.0–1.6 MPa, operating temperature 10–40 °C, ingress protection IP54–IP65 (IEC 60529), and weight 350–800 kg. Materials used include tool steel (e.g., D2, M2), carbide for coating or inserts, precision bearings, and aluminum or steel housing. These specifications are directory reference ranges; verify model-specific values with the manufacturer.

Working Principle

The slitting head uses one or more sets of precision-ground circular knives mounted on parallel arbors. The electrode web passes between upper and lower knife sets, where overlapping knives create a shearing action. Cutting width is set by spacers between knives. The head may be driven or idle, with precise alignment and minimal runout essential for clean, burr-free cuts and to prevent foil wrinkling or tearing.

Components / BOM

Upper Arbor Assembly
Holds the upper set of slitting knives. May be driven or idle, and often includes adjustment mechanisms for knife pressure and overlap.

Material: Alloy Steel
Lower Arbor Assembly
Holds the lower set of slitting knives, precisely aligned with the upper arbor to create the shear point.

Material: Alloy Steel
Slitting Knives/Razor Blades Part
The precision-ground circular cutting tools that perform the actual slitting of the electrode material.

Material: Tool Steel or Carbide-Tipped
Knife Spacers Part
Precision shims or rings placed between knives on the arbor to define the slit width.

Material: Hardened Steel
Bearing Housings
Support the arbors with high-precision bearings to ensure smooth, vibration-free rotation and minimal runout.

Material: Steel or Cast Iron
Side Plate/Housing Part
The rigid frame that holds the arbor assemblies in precise alignment and provides mounting points to the slitting machine.

Material: Steel or Aluminum
