UKO end mill can be divided into 45° 55° 65° and etc. According to coating, it can be divided into uncoated, PVD, and CVD. In addition, we can also divide the end mill into a flat ball nose and corner radius cutter. What’s the difference between these types? As a professional manufacturer of end mill, UKO tell you.

Flat end mill

Flat end mill is the most popular end mill for our customers, of which 2-flute, 3-flute, 4-flute, and 6-flute are very common. The less the flute number, the smoother the chip removal, and the more the flute number, the more precise the processing.

The flat end mill is widely used in groove processing, side processing, and step surface processing.

Ball nose end mill

Ball nose end mill is a kind of tool which is assembled on the milling machine with the cutter similar to the ball head and is used for milling various curved surfaces and arc grooves.

The ball nose end mill has the best effect on the machining curved surface, but the chip discharge performance is poor because of the small chip holding groove at the tip.

Corner radius end mill

Corner radius end mill is used for machining the corner R and periodic feeding. In periodic feed machining, even if R is small, it can also be used for end mills with a large diameter for efficient machining.

When the workpiece is large, the narrow concave area is less, the surface change is small, the relatively flat area is suitable for the corner radius end mill, and the narrow concave area is suitable for the ball nose end mill.

Whatever end mills or CNC inserts, customers often purchase the most general model. In fact, according to the performance of processing products and parameters of the CNC machine, selecting the most suitable products can greatly improve the production efficiency. In addition, UKO can provide product customization services.
