Indoors using a CNC cutting machine should be kept as good as possible, and it is advisable to use a cooling system such as a fan to keep the room cool, and at the same time prevent workers from suffering from heat stroke due to constant high temperature operations.
The steel plate is cut at a high temperature. After the cutting, there is still warmth on the steel plate. This high temperature is enough to scald the skin. After cutting, avoid touching the plate with hands. After the plate is completely cooled, it can be used by hand. After touching or cutting it, it can be removed with mechanical equipment.
When the CNC cutting machine cuts material, its temperature is very high. Some flammable materials such as chemical fiber clothes and documents cannot be placed next to the cutting steel plate or cutting torch to prevent burning. When rails and racks are used, they are prone to heat generation due to friction. Once too high heat is generated, it will affect the material of the parts. In order to prevent the generation of excessive heat, lubrication must be used before use.
Cutting site can not store some of the high-temperature explosive materials, such as gas cylinders, trachea is best not to stay at the cutting site. When using a CNC plasma cutting machine or a CNC flame cutting machine, the trachea and power cord application brackets are suspended in midair and should not be placed on rails or cutting planes to prevent damage and accidents.
When using a cutting machine, it is necessary to concentrate and cannot be diligent. The cause of many production accidents is caused by the lack of energy during operation. Turn off the power supply and air supply after use. The panel should be wiped clean to ensure the next use.
The most important thing in the use of CNC cutting machines in the summer is to focus on the safety and formal operation in accordance with the regulations. At the same time, care for maintenance can also make the service life longer.
1.cylindrical milling cutter
Used for processing flat surfaces on horizontal milling machines. Cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and spiral teeth according to tooth shape. According to the number of teeth and coarse teeth and two kinds of fine teeth. The helical tooth rough tooth milling cutter has fewer teeth, high tooth strength and large chip space, which is suitable for rough machining. Fine-tooth milling cutters are suitable for finishing.
2. face milling cutter
Also known as disc milling cutter, used for vertical milling machine, end milling machine or gantry milling machine processing plane, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. The structure has three kinds: integral type, insert type and transferable type.
3. End milling cutter
Used for processing grooves and step surface, knife teeth in the circumference and end face, can not work along the axial feed. When the end mill has end teeth through the center, axial feed can be provided.
4. Three-side edge milling cutter
Used for processing all kinds of grooves and steps, its two sides and circumference are provided with cutter teeth.
5. Angle milling cutter
For milling grooves at a certain Angle, there are two kinds of single Angle and double Angle milling cutters.
6.Saw Blade milling cutter
Used for machining deep grooves and cutting off workpieces, there are more cutter teeth on the circumference. In order to reduce the friction during milling, there are 15 '~1° auxiliary Angle on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail slot milling cutters, T - shaped slot milling cutters and various forms of milling cutters.
