Merely punching out the shape is just the beginning. A blade that withstands the brutal conditions of harvesting requires precision forming, controlled hardening, and a razor-sharp edge. Our Combine Harvester Cutting Blade Production Line integrates four critical stages into one cohesive system, ensuring each blade achieves optimal hardness, precise geometry, and long-lasting performance right on your factory floor.

Step 4: Precision Grinding for a Flat & Sharp Edge

✅ Turnkey Solution: From raw material to finished, hardened, and sharpened blade.

✅ Consistent Quality: Automated and controlled processes eliminate human variability.

✅ Increased Durability: The integrated heat treatment processing directly targets and enhances blade hardness and service life.

✅ Reduced Operational Cost: Streamlined workflow lowers labor dependency and intermediate handling.

J21/J23 power press is widely used in stamping and forming of electronic, communication, computer, household appliances, furniture, transportation, (automobile, motorcycle, bicycle) hardware parts, etc.

·J23 series Open Eccentric Presses is a general-purpose presses, suitable for forming, blanking, punching. bending and other cold stamping process.

·C-frame Casting fuselage,maximum rigidity and minimum deflection for accurate parts and long tool life. body can be tilted, , high rigidity and less deformation Compact. Thick plates and large columns provide you with the stable platform you need for your demanding application.

·The Machine use Rigid rotated bond clutch rigid and well supported. The clutch gives continuous strokes for mass production.

·Crank shaft is made of special alloy steel machined to close accuracy and fitted in bronze bushes for smooth working, longer life & accuracy.

·Properly sized flywheel, is made of high grade cast iron, for storing and releasing adequate energy for the pressing operations, and properly balanced for smooth running.

·Gear are of steel cast or fabricated. Gear teeth are generated by precision hobbing machine.

·Machine is with both hands button and foot switch control: anti-tie down, non-repeat controls with ring guards; conforms to OSHA.

·Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.
