What is the difference between end mills and key milling cutters?

The difference between end mills and keyway cutters:
1. The end mill is generally four-bladed and three-bladed, and the keyway cutter is two-blade (favorable to ensure the diameter accuracy after re-grinding);
2. The main cutting edge of the end mill is designed on the circumference. The end face is on the cutting edge, and the main cutting edge of the keyway milling cutter is on the end face, and the cutting edge is on the circumference.
3. Therefore, the end mill should not be constituted axially. It must be used. It can be a tendency into the knife or spirally. The amount is not so large, because the chip pocket on the cutting edge is shallow. The keyway milling cutter feeds in the axial direction.
Therefore, it will wear near the end, mainly re-grind the end, and the cutting edge will not re-grind to ensure the matching precision of the machining groove (H9, N9).

What is a corn milling cutter?

Corn milling cutter, otherwise known as corn cob milling cutter, is also called scaly milling cutter. The surface is dense spiral mesh, and the groove is relatively shallow. It is generally used for material processing such as some functional materials, especially like some composite materials such as carbon fiber Kraft materials (like the outer shell of an airplane’s wing) such as fiberglass! !

Solid carbide scaly milling cutter, the cutting edge is composed of numerous cutting units, the cutting edge is sharp, which greatly reduces the cutting resistance, and can realize high-speed cutting, achieving the effect of milling and grinding, and improving the composite material. Processing efficiency and surface quality extend the life of the milling cutter.

What is the difference between milling cutters and drill bits?

A twist drill is an instrument that cuts a circular hole of a workpiece by rotating relative to a fixed axis. It is so named because its cheap flute is spiral and shaped like a twist.

The main cutting edge of the end mill is a cylindrical surface, and the cutting edge on the end face is a minor cutting edge. At work, an end mill without a center edge cannot go anywhere the axial direction of the milling cutter. According to the national standard: the end mill has a diameter of 2-50mm and can be divided into coarse and fine teeth. Diameters 2-20 are straight shank ranges and diameters 14-50 are tapered shank ranges.
