Common types of customized cutting tools end mill and precautions for use
customized cutting tools end mill is a kind of milling cutter used very much on CNC machine tools. customized cutting tools end mill has cutting tools on both cylindrical surface and end face, they can cut simultaneously or separately. It is mainly used for flat milling, groove milling, step surface milling and profile milling.
The main types of customized cutting tools end mill.
1、Straight shank end mill
2、Morse taper shank end mill
3、Sleeve type end mill
4、Integrated carbide end mill
5、Straight shank end mill with carbide spiral teeth
6、Morse taper shank carbide spiral tooth end mills
7、Taper shank carbide spiral tooth end mill

Notes on the use of the customized cutting tools end mill.
Most of the customized cutting tools end mill machining is done in a spring-loaded clamping set, which is in a cantilevered state when used. In the milling process, sometimes there may be end mills from the tool holder gradually protrude, or even completely fall off, resulting in the scrapping of the workpiece. The reason for this is generally the existence of oil film between the inner hole of the tool holder and the outer diameter of the end mill shank, resulting in insufficient clamping force.
customized cutting tools end mill factory is usually coated with anti-rust oil, if cutting using non-melting cutting oil, the tool holder bore will also be attached to a layer of foggy oil film, when the shank and the tool holder have oil film, the tool holder is difficult to firmly clamp the shank, in the processing of the end mill is easy to loose fall off. Therefore, before the end mill is clamped, the end mill shank and the inner hole of the tool holder should be cleaned with cleaning solution and dried before clamping.
When the diameter of the customized cutting tools end mill is large, even if the shank and the tool holder are clean, the tool may still fall off, so you should use a shank with a flattened notch and the corresponding side locking method.
customized cutting tools end mill clamping may appear after another problem is the processing of end mills in the tool holder port break, the reason is generally because the tool holder used for too long, the tool holder port has worn into a taper, then should be replaced with a new tool holder. Add the workpiece shape accuracy: change the down milling to reverse milling; reduce the machining allowance; replace the chuck or collet; reduce the tool overhang; improve the cutting speed. Solution of poor straight angle: reduce machining allowance; replace chuck or collet; reduce tool overhang; increase cutting speed; change 2 flute end mill to 4 flute end mill; reduce feed; check tool wear and replace with new tool.
