Does the carbide end mill need to add working fluid?

Carbide milling cutters are milling cutters made of cemented carbide. To understand the cemented carbide milling cutter, we must first know what is a hard alloy. The cemented carbide is based on the carbide (WC, TiC) micron powder of high hardness refractory metal, with cobalt (Co) or nickel (Ni). Molybdenum (Mo) is a binder and is a powder metallurgy product sintered in a vacuum furnace or a hydrogen reduction furnace.

When the carbide indexable milling cutter is used to mill steel, the cutting fluid is generally not cast. When the cutting fluid is sufficient for sufficient cooling, the cutting fluid (generally water-soluble cutting fluid) can also be poured. In the case of finishing, in order to improve the tool life and the surface quality of the workpiece, it is best to use the cutting fluid to cool it sufficiently. Carbide milling cutters must be machined with cutting fluid at the same time or in advance, and do not allow the casting to start in the middle of the cutting.
When milling stainless steel, non-water-soluble cutting fluids are generally used to improve milling performance.
When milling cast iron, the cutting fluid is generally not used, and the cutting fluid is used only in rare cases to solve the dust problem during cutting.
When milling aluminum alloys, cutting fluids can be used, mainly for cooling and improving the surface quality of the workpiece.
When the end mill and the three-face milling cutter are used for the machining of the groove, it is recommended to use a water-soluble cutting fluid or compressed air for sufficient cooling because of the closed cutting and high temperature.

Maintain

When the cemented carbide milling cutter axis line and the workpiece edge line coincide or approach the edge line of the workpiece, the situation will be very serious, the operator should do the relevant equipment maintenance work:
1. Check the power and stiffness of the machine to ensure that the required cutter diameter can be used on the machine.
2. The overhang of the tool on the spindle is as short as possible, reducing the influence of the axis of the milling cutter and the position of the workpiece on the impact load.
3. Use the correct milling pitch suitable for this process to ensure that there are not too many blades to engage the workpiece at the same time to cause vibration during cutting. On the other hand, ensure that there are enough blades when milling narrow workpieces or milling cavities. Engages with the workpiece.
4. Make sure that the feed per blade is used to achieve the correct cutting results when the chips are thick enough to reduce tool wear. The indexable insert with positive rake groove shape provides smooth cutting results and lowest power.
5. Use a milling cutter diameter that is appropriate for the width of the workpiece.
6. Use the correct lead angle.
7. Place the milling cutter correctly.
8. Use cutting fluid only when necessary.
9. Follow tool maintenance and repair rules and monitor tool wear.
Proper maintenance of carbide milling cutters can extend tool life and increase work efficiency.
