(1) High productivity When milling, the milling cutter rotates continuously and allows high milling speed, so it has high productivity.

(2) Interrupted cutting When milling, each tooth is in intermittent cutting, especially in end milling, the milling force fluctuates greatly, so vibration is unavoidable. When the frequency of vibration is the same as or a multiple of the natural frequency of the machine tool, the vibration is most serious. In addition, when high-speed milling, the cutter teeth are subjected to periodic cold and thermal shocks, which are prone to cracks and chipping, which reduces the durability of the cutter.

(3) Multi-knife and multi-blade cutting The milling cutter has many teeth, and the total length of the cutting edge is large, which is conducive to improving the durability and productivity of the tool, and has many advantages. But there are also the following two problems: First, the cutter teeth are prone to radial runout, which will cause uneven load on the cutter teeth, uneven wear, and affect the quality of the machined surface; second, the chip space of the cutter teeth must be sufficient. , otherwise it will damage the teeth.

(4) Different milling methods According to different processing conditions, in order to improve tool durability and productivity, different milling methods can be selected, such as up-cut milling, climb milling or symmetrical milling, asymmetrical milling.

Taper Shank End Mills

Taper shank end mills are also known as Morse taper shank end mills, with specifications ranging from 6mm to 100mm. It consists of a blade and a Morse taper.

Uses: Morse taper shank end mills (coarse teeth) are used for rough machining of planes, steps, grooves, and mutually perpendicular planes.

Features and accuracy: The number of teeth of the milling cutter is small, the chip space is large, and it is suitable for rough machining.

Climb milling helps prevent edge damage and increases tool life. But there are two points to pay attention to: ① If using ordinary machine tools, try to eliminate the gap of the feed mechanism; ② When the surface of the workpiece is left with an oxide film or other hardened layer formed by the casting or forging process, up-milling should be used.

Keyway milling cutter difference

1. The keyway milling cutter cannot process the plane, while the end mill can process the plane.

2. The keyway milling cutter is mainly used for processing keyway and groove, and the keyway milling cutter is very useful for milling keyway. For example, a 6MM end mill and a keyway milling cutter 6MM are more likely to be slotted than a 6MM end mill, and the end mill is easy to break, while the keyway milling cutter can pass through it in one go.

3. The cutting amount of the keyway milling cutter is larger than that of the end mill.
