What is a composite material cutting machine

Yuchen CNC cutting machine is suitable for composite materials industry. It can cut various composite materials, such as aramid cloth, carbon fiber, prepreg cloth, glass fiber and ceramic fiber. Therefore, a cutting machine suitable for the composite material industry is also called a composite material cutting machine. Many customers say that I have a lot of materials, how do I choose the configuration and tools of the cutting machine? Because Yuchen has 10 years of experience in serving composite materials customers, the following is how to choose the most suitable configuration for commonly used composite materials when buying a cutting machine

1. First look at which tools are needed for carbon fiber?

Recommended tool selection: Driven Rotary Knife Tool

Blade selection Y025a

Since carbon fiber cloth is the raw material for processed products, the carbon fiber compression molding process mainly includes four steps: preheating, feeding, clamping, curing, and demolding. The produced carbon fiber products are polished and processed into finished products. There is a lot of margin when blanking, so cutting precision is not required! Customers can accept errors within 1 mm

Therefore, it is generally recommended that customers choose belt feeder.

2. Which tool should I choose for cutting prepreg?

It is recommended to use a vibrating knife, and choose different blades according to different material thicknesses

Prepreg processing technology and precision requirements:

Carbon fiber prepreg is made by combining epoxy resin and carbon fiber through high pressure and high temperature technology. The composite material made of carbon fiber yarn, epoxy resin, release paper and other materials through coating, hot pressing, cooling, lamination, winding and other processes is called carbon fiber prepreg, also known as carbon fiber prepreg. Pre-impregnated cloth can be directly processed into products through molds with high precision requirements. Some customers require that the cutting accuracy is less than 5 lines, it is best to choose a rack-mounted machine!

3. What kind of tools do I need to choose for cutting glass fiber?

Glass fiber checkered cloth is a kind of untwisted roving plain weave fabric, which is an important substrate for hand-laid glass fiber. The strength of gingham cloth is mainly in the warp and weft direction of the fabric. For occasions requiring high warp and weft strength, it can also be woven into unidirectional fabric. It can arrange more untwisted rovings in the warp and weft direction. Warp cloth, single weft cloth.

It is recommended to choose a round knife

Fiberglass cloth is usually used as a reinforcing material in the national economy, such as composite materials, electrical insulation materials and thermal insulation materials, and circuit boards. 2. Glass fiber cloth is mainly used in hand lay-up process. Fiberglass cloth is mainly used for ship hulls, storage tanks, cooling towers, ships, vehicles, storage tanks, etc. 3. Glass fiber cloth is widely used for wall reinforcement, external wall insulation, roof waterproofing, etc. Due to the characteristics and uses of the material, cutting accuracy is not required! The customer accepts the error is about 1 mm

Under normal circumstances, it is recommended to use a belt feeder, if the cutting requirements are strict, it is recommended to use a rack-mounted machine.

4. What kind of tool should I choose to cut aramid cloth?

It is recommended to choose a vibrating knife

Prepreg: do not consider carbon fiber, glass fiber or aramid fiber materials

Prepreg is an airtight material, so the cutting machine is a vibrating knife! The width of this material is 1 meter wide, which is basically a roll of 100 meters long. Material. Recommend 1625 automatic feeder (Note: some customers' products have a long single piece length, and the machine can be lengthened according to customer requirements

Other: Carbon cloth recommended vibrating knife

Whether it is carbon fiber cloth, glass fiber cloth or aramid cloth, they are all woven fabrics. These materials are breathable. They are usually cut with a round knife. Carbon fiber cloth is usually no more than one meter wide. Follow-up customers need to have a single manufacturer that can do the most extensive. 2.5 meters wide. The width of fiberglass cloth is usually one meter to two meters, and the width of aramid cloth is usually within 2.5 meters. Therefore, the machine model can be recommended to customers according to their material and width requirements!
