A good selection of tools can increase the efficiency of the machining center by 30%

The tools selected according to different purposes are also different. Choosing the right tool can not only ensure the stability of processing, but also improve the processing efficiency. Machining centers are widely used in the production of fixtures and molds, mechanical parts processing, handicraft carving, medical device industry manufacturing, and education and training industries. The tools selected according to different uses are also different. Choosing the right tool can not only ensure the processing Stable and can improve processing efficiency. Next, I will introduce several kinds of tools for you to use in different processing occasions.

1. Face milling cutter Face milling cutters are mainly used for processing planes and step surfaces on vertical milling machines. The main cutting edge of the face milling cutter is distributed on the cylindrical surface of the milling cutter or the cone surface of the circular machine tool electrical appliance, and the secondary cutting edge is distributed on the end surface of the milling cutter. According to the structure, face milling cutter can be divided into integral face milling cutter, cemented carbide integral welding face milling cutter, cemented carbide machine clamp broken face milling cutter, cemented carbide indexable face milling cutter and other forms.

2. Cylindrical milling cutters Cylindrical milling cutters are mainly used to process planes on horizontal milling machines. Cylindrical milling cutters are generally integral. The material rod of the milling cutter is high-speed steel, the main cutting edge is distributed on the cylindrical surface, and there is no secondary cutting edge. Milling cutters are divided into coarse and fine knives. The rough tooth milling cutter has a small number of teeth. The tooth strength is large, the chip holding space is also large, and the number of regrinding times is large, which is suitable for rough machining. The fine-tooth milling cutter has a large number of teeth and works smoothly, which is suitable for finishing. (Guide: How to take out a broken screw? Six tips for taking out a broken screw) 3. Keyway milling cutter Keyway milling cutters are mainly used for processing round head closed-key high-speed machining center grooves on vertical milling machines. Chenghai machine tool technical experts explained: the shape of the milling cutter is like an end mill, the end face has no center hole, the end face cutter is opened from the outer circle to stop the center, and the helix angle is small, which enhances the strength of the end face cutter. The cutting edge on the face tooth is the main cutting edge, and the cutting edge on the cylindrical surface is the secondary cutting edge. When processing the keyway, feed a small amount along the axial direction of the milling cutter each time, and then feed it along the radial direction. This is repeated many times, that is, the machine tool electrical appliance can complete the processing of the keyway.

4. End milling cutter End milling cutter is the most widely used milling high-speed machining center cutter in CNC machining center milling processing. It is also the most equipped machining center tool in Chenghai CNC. It is mainly used for processing grooves, step surfaces and forming surfaces on vertical milling machines. The main cutting edge of the end mill is distributed on the cylindrical surface of the milling cutter, and the secondary cutting edge is distributed on the end face of the milling cutter, and there is a central hole in the center of the end face. Therefore, it is generally not possible to make a feed movement in the radial direction of the milling cutter during milling. The feed movement can only be carried out in the radial direction of the milling cutter. End mills also have coarse machine tool electrical teeth and fine teeth. The coarse-tooth milling cutter has 3-6 teeth, which are generally used for rough machining; the fine-tooth milling cutter has 5-10 teeth, which is suitable for finishing. . The diameter range of the end mill is 2-80mm, and its shank has various forms such as straight shank, Morse taper shank and 7:24 taper shank.
