251 x 8.2 x 2.8 mm Cutter Blade for Shima Seiki Automatic Cutter Parts

The 251 x 8.2 x 2.8 mm cutter blade is designed for compatible Shima Seiki automatic cutting machines using the same blade dimensions and installation structure.

The blade is installed inside the cutter head and performs continuous reciprocating cutting during machine operation. Correct blade dimensions and stable installation help maintain smooth movement, consistent cutting depth and reliable production performance.

This product is suitable for replacing blades that are worn, bent, damaged or no longer providing satisfactory cutting results.

Because different cutter models may use blades with similar appearances but different dimensions, customers should provide the machine model and old blade photos before ordering.

The cutter blade is one of the main consumable parts inside an automatic cutting machine.

During production, the blade moves repeatedly through multiple layers of material according to the cutting path generated by the machine control system.

A correctly matched blade helps maintain stable cutting movement and consistent cutting depth.

When the blade becomes dull, bent or damaged, cutting resistance may increase and the material may not be cut completely. The machine may also produce rough edges, inaccurate cutting lines or abnormal vibration.

Replacing the blade at the correct time helps restore normal cutting performance and reduce unnecessary stress on the cutter head mechanism.

Actual cutting performance depends on the cutting material, lay height, machine condition, blade setting, sharpening condition and operating speed.

• The blade has become dull
• The cutting edge is damaged
• The blade is bent or deformed
• The material cannot be cut completely
• The material edge becomes rough
• Cutting resistance increases
• The cutter head produces abnormal vibration
• The blade requires sharpening too frequently
• Cutting accuracy becomes unstable
