Classifications and tips of Cemented Carbide slitter blades


Cemented carbide slitter blades are cutting tools with vital preciseness. It can lessen machine downtime.Tungsten carbide slitter blades are divided into upper knife and lower knife. It is installed on cutter shaft. Cemented Carbide slitter blade cut various material like capacitor paper, aluminum foil, metallized film, foam, mesh and other materials with thickness of 0.01mm-0.1mm under accordance of rolling shear. Cemented carbide slitter blades are separated to square knife slitting and circular knife slitting because of shape is different.


Carbide Square knife slitting refers to fix carbide square blades on cutter frame, drop the knives in the process of material operation, cut material longitudinally to reach purpose of slitting. Cemented carbide square slitting knives including single sided blade and double-sided blade.

Single-sided slitting blade keeps better when cutting thick film with excellent rigidity. On account of hard blade is not easy to shift under high speed of slitting machine, which will guarantee product quality. Single-sided blade is recommended for thickness of 70-130um.


Double-sided blade is softer than single-sided blade.It is fit for slitting some material thinner. In this way smoothness of film edge is ensured and blades' service life can be prolonged. Double-sided blade is recommended for thickness under 70um.


For slitting method, carbide square knife slitting contains slotting and suspended slitting. Slotting means while material is running on grooving roller, drop cutter in the groove, and cutting material longitudinally. At this time, material gets a certain angle in slotting roll, which is not easy to draft. When processing and slitting PP film or thin film with narrow edge material, slotting can improve efficiency. Disadvantage of slotting is that is more troublesome to set the cutter compared to suspended slitting. Suspended slitting refers blades fall down to slit material longitudinally when material passes through the rollers. Material keeps stable at this time. Though its slitting accuracy is lower than slotting, but it is more convenient.

When purchase cemented carbide slitting blades, do not only pursuit imported blades.There is no best tungsten carbide slitter blades, only suitable blades. Key to slitting effect of blades is application. Correctly handle relationship among blade performance, price and stability.

 

Cemented carbide slitter blade is suitable for processing solid wood, density board, gray cast iron, chilled cast iron, stainless steel, non-ferrous metal, etc.

Our tungsten carbide slitting blade has excellent hardness, high hardness, good wear resistance, high modulus of elasticity, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation resistance), low impact toughness, low expansion coefficient, and similar thermal and electrical conductivity with iron and its alloy.
