Stainless Steel Knife Blade Production Line

This line moves stainless steel blanks through five dedicated stations — leveling, double-sided polishing, back polishing, edge grinding, and serration — replacing fragmented manual processes with purpose-built machines that reduce labor requirements and improve part-to-part consistency.

The SM-300A grinder rotates its wheel at 2,054 r/min with a maximum stroke of 450 mm and grinding length of 380 mm, delivering repeatable edge geometry across production runs. An onboard 150W water pump maintains continuous cooling to prevent blade warping or temper loss during grinding.

The BPG-600 polisher’s 17 kW motor and 600×400 mm working area handle large batches of blades efficiently, while φ250 mm polishing wheels provide the contact surface needed for streak-free, mirror-quality finishes on both sides of the blade in a single pass cycle.

The BKC-250 serration machine uses adjustable wheel configurations (φ250 × N) to produce different tooth patterns — from fine micro-serrations to deep bread-knife teeth — without retooling the entire station, giving manufacturers flexibility across product lines.

Machines in this line range from 52 kg (BPG-2) to 2,100 kg (BPG-600), built with painted steel frames, hydraulic control systems, and geared drive trains engineered for continuous factory-floor operation across multiple shifts.
