{"product_id":"esccbgm","title":"ECS-S Benchtop Grooving Machine for Cylindrical Cells (Ø10-50mm, L20-140mm), ESCCBGM","description":"\u003cp\u003eA cylindrical cell grooving machine is a precision tool used to create a uniform inward \"bead\" or shoulder near the open end of a battery steel case. This groove serves as the structural seat for the gasket and cap (header) and is essential for achieving a hermetic seal during the subsequent crimping process.\u003c\/p\u003e\n\u003cp\u003eWhen selecting a machine for formats like 18650, 21700, or the larger 4680, look for these critical parameters: (1) \u003cstrong\u003eGrooving Depth\u003c\/strong\u003e: Typically adjustable between 1.2 mm and 2.0 mm. For 4680 cells, look for reinforced systems that can handle the thicker steel walls. (2) \u003cstrong\u003eGrooving Width\u003c\/strong\u003e: Standard is 1.1 mm to 1.5 mm, depending on the blade thickness.  (3) \u003cstrong\u003ePrecision\u003c\/strong\u003e: High-end models offer accuracy within ±0.1 mm. (4) \u003cstrong\u003eBlade Durability\u003c\/strong\u003e: Quality tungsten steel or alloy blades should last for \u0026gt;1,000,000 cycles. (5) \u003cstrong\u003eCompatibility\u003c\/strong\u003e: Most R\u0026amp;D units come with an 18650 die but offer swappable molds for 21700, 26650, or 32650.
