Cemented Carbide Cutting Machine Blade Composition Structure and Development Application

Brief introduction of carbide cutting machine blade:

Commonly known as the cutting foot machine blade, also known as the cutting foot machine blade, the cutting foot knife. Because the shape is round, it is also called disc cutter. It is mainly used for cutting the lead pins of electronic circuit boards on the cutting machine.

Ingredient structure

The specifications of the blades of the cutting foot machine are mainly Φ250Φ703.5 and Φ200Φ703.5, which are commonly referred to as 10 inches and 8 inches. The main material is cemented carbide. The main component of cemented carbide is tungsten carbide, so it is also called tungsten steel, so it is also called tungsten steel cutting machine blade. Cemented carbide is widely used in cutting tool manufacturing industry as a material with high hardness, high strength, wear resistance and corrosion resistance. Due to the brittleness of cemented carbide, it cannot be cut directly, and it is difficult to make integrated tools with complex shapes. Therefore, inserts of different shapes are often made and installed on the cutter body or mold body by welding, bonding, mechanical clamping, etc. use.

Development and Application

With the extensive development of the electronics industry, the market demand for printed circuit boards, the production of cutting blades is also a development of cutting tools. There are two main forms related to circuit board production: one is solder pins with plug-ins, and the other is directly formed by patches. Since the production equipment in the form of patch is relatively high-end and the investment required is relatively high, most of them still use the cutting insert of the foot cutter blade.

The solder pins of the circuit boards with plug-in units are also divided into thickness and softness. According to different job requirements, the performance requirements of the blades of the leg cutter are also different. Of course, the cutting performance is also related to the cutting machine itself. With the continuous development of my country's cemented carbide-related materials, the market will have higher requirements on the blades of the cutting machine to meet the objective needs of the development of the electronics industry.

Use and attention

Cemented carbide has the characteristics of brittleness, improper use or operating errors will often cause accidental damage to the blade, and serious cases will lead to dangerous accidents. In order to use the blade of the foot cutter correctly and safely, the following precautions must be strictly followed (by Zhuzhou Provided by Sanxin Cemented Carbide Production Co., Ltd.):

1. Check by listening: Before installing the blade, hook the blade with a finger and hang it in the air. Use a wooden hammer to tap the blade a few times and listen to the sound. If there is a dull sound, there are often cracks. The use of this blade is forbidden to avoid accidents!

2. Running speed: The working speed of the foot cutter should be limited to 4500 rpm or less.

3. Blade installation: The rotation axis must be accurately aligned with the center of the blade. After the blade is installed, there should be no deception. When installing the blade, the blade and mechanical installation surface should be carefully cleaned, and no cutting materials, dust or other impurities should be left. , Then fix the blade.

4. Install the protective device: The protective cover must be installed before the blade runs (the blade studio should be surrounded by baffles, steel plates, rubber and other protective equipment).

5. Test machine: After the blade is installed, run the machine empty for 5 minutes and observe carefully. Vibration or other abnormal sounds are absolutely not allowed. If there is, stop the machine immediately to check the cause before use.

6. Blade storage method; it is strictly forbidden to write or mark on the blade with electric engraving or other scratching methods. The cutting edge of the blade is very sharp, but it is very brittle. Avoid the blade from being hit. The ready-to-use blade should be stored properly. Don't just put it aside.
