LCB vs CB Steel Rule Die Cutting Blades In steel rule die cutting, selecting the right die cutting steel rule is critical to achieve clean edges, stable cutting, and long tool life. Among all die cutting blades, LCB (Long Center Bevel) and CB (Center Bevel) are the two most commonly used profiles, each designed for different materials and cutting requirements. 1.

When manufacturing rotary dies, the quality of the rotary die board (rotary shell) plays a critical role in cutting accuracy, machine stability, and tool lifespan. Poor-quality shells can lead to uneven cutting, vibration, and increased wear on laser or die-cutting equipment. Below is a simple 5-step inspection guide to help you quickly and accurately distinguish high-quality rotary die boards from inferior ones. Step 1: Inspect the Surface Carefully check the outer surface of the rotary shell for wormholes, scars, cracks, or defects. A clean and uniform surface indicates good raw material selection and proper processing. Step 2: Measure the Thickness Use a caliper to measure the shell thickness at multiple points. Inconsistent thickness often leads to cutting deviation during production. Step 3: Check Bottom & Middle Diameters Measure the diameters at both ends and the middle of the rotary shell. This tolerance ensures the shell fits properly onto the rotary
