How to use Discount micro dia end mills
Discount micro dia end mills are usually coated with anti-rust oil when they leave the factory. If non-water-soluble cutting oil is used for cutting, a misty oil film will also adhere to the inner hole of the tool holder.

1. Clamping of Discount micro dia end mills
Discount micro dia end mills are usually coated with anti-rust oil when they leave the factory. If non-water-soluble cutting oil is used for cutting, a misty oil film will also adhere to the inner hole of the tool holder. The tool holder is difficult to firmly clamp the tool holder, and the end mill is easy to loose and fall off during processing. Therefore, before the end mill is clamped, the shank of the end mill and the inner hole of the tool holder should be cleaned with cleaning fluid, and then dried before clamping.
2. Discount the vibration of micro dia end mills
Due to the tiny gap between the Discount micro dia end mills and the tool holder, the tool may vibrate during machining. Vibration will make the cutting amount of the circumferential edge of the end mill uneven, and the cutting and expansion amount will be larger than the original value, which will affect the machining accuracy and tool life.
3. Discount micro dia end mills for end cutting
In CNC milling of workpiece cavities such as molds, when the point to be cut is a concave part or a deep cavity, it is necessary to lengthen the protrusion of the end mill. If the long-blade type Discount micro dia end mills are used, the deflection of the tool is large, and it is easy to generate vibration and cause tool breakage. Therefore, in the process of machining, if only the cutting edge near the end of the tool is required to participate in the cutting, it is best to use a short-edged and long-shank end mill with a longer overall length of the tool.
4. Selection of cutting parameters
The choice of cutting speed mainly depends on the material of the workpiece to be machined; the choice of feed rate mainly depends on the material of the workpiece to be machined and the diameter of Discount micro dia end mills. The tool samples of some foreign tool manufacturers are attached with a tool cutting parameter selection table for reference.
5. The choice of cutting method
Climb milling helps prevent edge damage and increases tool life. But there are two points to note:
① If using ordinary machine tools, try to eliminate the gap of the feeding mechanism;
② When the surface of the workpiece has an oxide film or other hardened layer formed by the casting or forging process, it is advisable to use up milling.
6. Use of Discount micro dia end mills
Discount micro dia end mills have a wide range of use and requirements, and even if the cutting conditions are slightly inappropriate, there will not be too many problems. Although the cemented carbide end mill has good wear resistance in high-speed cutting, its application range is not as wide as that of the high-speed steel end mill, and the cutting conditions must strictly meet the requirements of the tool.
