CNC P046/P017-1300 Slitting Machine Steel Parts

What is a slitting machine?
1300FT - P046/P017 - 1300 Slitting machine steel parts are the key parts of the slitting machine.

Slitting machines are used to cut coils longitudinally. They are widely used in metal processing, papermaking, leather and other industries.

They can cut wide materials into narrow materials according to the set width for subsequent processing or use. Their structure includes unwinding, cutting, and winding parts.

Steel parts are usually made of high-quality steel, which is of great significance to the stable and accurate operation of the slitting machine.
They are used to support the structure and operation of the slitting machine, such as carrying knives and transmission parts, which can effectively improve production efficiency and material utilization.

How much precision is required? (For reference only)
The steel parts of the slitting machine have high requirements for dimensional accuracy. For example, the dimensional tolerance of the tool installation part is generally between ±0.05mm - ±0.1mm to ensure the accuracy of the tool installation position and the slitting width. The accuracy requirements of the holes in the key transmission connection parts are also very high, requiring precise processing technology.

Shape accuracy is also critical. The flatness or cylindricity of the surface of the slitting machine coil guide parts is strictly required. The flatness must reach about ±0.02mm/1000mm to ensure the smooth operation of the coil without deviation.

What are the material requirements?
The hardness and toughness of the steel used for slitting machine parts (such as high-strength alloy steel and stainless steel) make processing challenging. High-strength alloy steel has high hardness and causes great wear on the tool during cutting. It is necessary to select appropriate tool materials (such as carbide tools) and cutting parameters (speed, feed rate, cutting depth) to ensure quality and efficiency. Stainless steel has good toughness and viscosity, and it is easy to produce built-up edge during processing, which affects the surface quality. It is necessary to use appropriate cooling and lubrication methods such as emulsion cooling and optimize cutting parameters to avoid it.

What are the process requirements?
First, forging is used to improve the internal structure of steel and enhance the mechanical properties of steel parts. The forged blank is first rough-machined (such as rough milling and rough turning) to remove a large amount of excess, and then fine-machined (fine milling, fine turning, boring, EDM, etc.) to meet the requirements of size and shape accuracy.

Parts with special requirements may require surface treatment processes such as quenching and nitriding to improve surface hardness and wear resistance. Frequent quality inspections during processing (such as three-coordinate measurement, hardness inspection, flaw detection, etc.) increase the complexity of the process.

 In what fields are slitting machines used?
1. Metal processing industry: used for steel, non-ferrous metal coils and plates processing, such as slitting of materials related to automobiles, home appliances, architectural decoration, and hardware products.
2. Papermaking industry: used for paper slitting to meet the width requirements of printing and packaging paper.
3. Textile industry: fabric slitting, used for clothing accessories and home textile products.
4. Leather industry: leather slitting, which is conducive to leather production and reduces waste.
5. Plastic film industry: film slitting, to ensure quality, used in packaging, agriculture and other fields.
