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! !

Corn milling cutter

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 a corn cutter and Wave edge milling cutter

Wave edge milling cutter, which is based on the spiral rake face of an ordinary high-speed steel end mill, and uses a special milling fixture to reprocess the spiral rake face into a wavy spiral surface, which intersects the flank face into a wavy cutting blade. The peaks and valleys of two adjacent waved edges are staggered along the axis by a certain distance, so that the cutting width is significantly reduced, and the actual cutting thickness of the cutting edge is increased by about three times. The cutting edge avoids the surface hardened layer and cuts into the workpiece. The wavy edge makes the inclination angle, working rake angle and cutting load of the cutting edge different at all points. And the wave blade makes the tooth pitch in the same end section different. These factors greatly reduce the periodicity of cutting force changes, making the cutting process more stable. When milling workpieces with rough surfaces such as gas-cut steel plates, the wave-shaped end mills can especially show their excellent cutting performance.

Wave edge milling cutters are spiral milling cutters. Corn milling cutters generally refer to insert-type milling cutters, and spiral blades refer to integral milling cutters. The general corn milling cutter is suitable for large-scale deep hole machining, while the spiral blade milling cutter is suitable for various face milling, side milling and complex profiling milling

What is the difference between milling cutters and drill bits?


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.
