The circular knife is widely used for slitting paper, plastic films, cloth, foam, rubber, copper foils, aluminum foils, graphite, etc. This kind of knife is ground by professional equipment. Its nice appearance, high precision, and durable life make it has high-cost performance. hoose high-quality raw materials Rough forming Vacuum heat treatment Cooling and tempering Testing hardness Finish grinding size Product testing Anti-rust spray Marking packaging.
The paper cutter blade is one of the important parts of the paper cutter, which is widely used in the papermaking and printing industry. Paper cutter blades are used in papermaking, printing and other industries. The sharpness and service life of the blades greatly affect the working efficiency of the paper cutter.

refiner blade :	1. multi-blade cutter ring 2. single-blade cutter ring 3. smooth cutter ring
Application :	mainly used in paper-making machinery and the paper roll industry
Blade manufacturing process:	The shape of the blade is round, and the blade needs to go through the processes of cutting, forging, shaping, turning shape, heat treatment, grinding outer circle, inner hole, fine grinding, turning knife edge, storage, packaging, storage, etc.

Pneumatic knife holders are operated by using the energy of compressed air provided by an air compressor as the power source.


The pneumatic knife holder adopts one - piece forming design.
And provide good rigidity and strength, and can quickly combine with the knife, to achieve accurate alignment of the knife.
It has the advantages of time-saving, speed, and stability.


In modern high-performance production equipment, operating speed is higher, and cutting is more difficult.

So the need for more innovative, more professional solutions. According to the specific needs of customers, we provide tailor-made products, product life longer, more robust and reliable, better performance, and more convenient operation, to meet their requirements for the maximum return on equipment investment.
