Hollow Rod Circular 7.7 Mm Cigarette Machine Knife

Hollow Rod Specialized Circular Cutter Of Cigarette Assembly Line For Last Cutting Process Of Filters With Cigarette Rod

Filter Knife is a component of cigarette making machines to slice filter rod after being connected to cigarette rod.

Customization

Regular filter Knives are for 108mm - 126mm long filter rods, filled with acetate tows. For hollow filters the knives had to be sharper.

Please provide detailed info. to us if your desired specs is different.

Depending on filter rod diameter and cigarette making machine model and other factors, time needed for manufacturing can vary. Thus details of product and relative lead time must be negotiated beforehand to avoid any discordance.

Heat Treatment Of Martensitic Stainless Steels

Austenitizing, where the steel is heated to a temperature in the range 980–1,050 °C (1,800–1,920 °F), depending on grade. The resulting austenite has a face-centered cubic crystal structure.

Tempering. Martensite would be heated to around 500 °C (932 °F), held at such high temperature, then air-cooled. Higher tempering temperatures decrease yield strength and ultimate tensile strength but increase the elongation and impact resistance.

Quenching. The austenite is transformed into martensite, a hard body-centered tetragonal crystal structure. The quenched martensite is too hard and brittle for most applications. Some residual austenite may remain.

Usages

Ferritic stainless steels are cheaper than austenitic steels and present in many commercial products, which include:

Building components, such as slate hooks, roofing, and chimney ducts

Power plates in solid oxide fuel cells operating at temperatures around 700 °C (1,292 °F) (high-chromium ferritics containing 22% Cr)

Architectural and structural applications (Type 430, which contains 17% Cr)

Household goods, such as kitchenware, sinks, and major appliances

Automobile exhaust pipes (Type 409 and 409 Cb[2] are used in North America; stabilized grades Type 439 and 441 are used in Europe)
