Factors that should be considered in the selection of cemented carbide milling cutters
When selecting cemented carbide milling cutters, the dimensional accuracy requirements of cutting processing must first be considered.

1. Machining accuracy
When selecting cemented carbide milling cutters, the dimensional accuracy requirements of cutting processing must first be considered. Generally speaking, the smaller the diameter of the machined hole, the smaller the tolerance. Therefore, milling cutter manufacturers usually classify milling cutters according to the nominal diameter size of the hole being machined.
2. Processing stability
In addition to considering the cutting accuracy requirements, the stability of the machine tool should also be considered when selecting a milling cutter. Machine tool stability is critical to the safe service life and cutting accuracy of milling cutters, so the working conditions of machine tool spindles, fixtures and accessories need to be carefully checked.
3. Chip removal and coolant
Chip removal is a problem that cannot be ignored in cutting. In fact, the most common problem encountered in machining is poor chip removal (especially when machining low-carbon steel workpieces), and this problem cannot be avoided no matter what kind of drill is used. Machining shops often use external injection of coolant to assist in chip removal, but this method is only effective when the depth of the processed hole is smaller than the diameter of the hole and the cutting parameters are reduced.
4. Processing cost per hole
Productivity or cost per hole is the most important factor affecting machining. To increase productivity, milling cutter manufacturers are working on machining methods that can integrate multiple operations and developing cutting tools that can achieve high-feed, high-speed machining.
