Automatic steel bar cutting machine
Steel Bar Shearing Machine CJ-80
CJ-80, an automatic shearing cutting machine specially designed for round bar cutting. It features high speed and efficiency, making it ideal for use in the fastener manufacturing industry.
Features:
-
Equipped with a fully automatic feeding rack that automatically centers the material. No manual feeding, flipping, or alignment required — one operator can manage multiple machines, reducing labor intensity and saving costs.
-
Adopts a fully enclosed flip-top blade mold design for easy tool change; it can rotate 360° for repeated use, offering longer service life.
-
Reinforced gear made of alloy steel with standardized heat treatment for greater transmission torque.
-
Crankshaft made of high-strength alloy steel with excellent rigidity and fatigue resistance.
-
Professional-grade bimetal sliding guide rails provide superior wear resistance and durability.
-
Automatic oil pump lubrication system for guide rails, with automatic alarm when oil supply is interrupted.
-
Well-designed material stopper mechanism ensures precise cutting length and easy adjustment.
-
Enclosed gearbox with oil-immersed gears and bearings provides reliable lubrication.
-
Optimized stopper design delivers higher cutting accuracy, smaller weight deviation, and smoother cut surfaces.
