And face milling cutters, also known as end mills, end mills is a standard machine tool, often used in the horizontal milling, and its shape is like eating "fried the middle of a round hole, " the outer circle, and two near the outer end The site has a round cutting edge, (like the wide jagged) edge on three sides so I have a whole set of teeth, materials commonly used W18Cr4V, size and width by diameter size (Bo Hou) had nearly a hundred species. The knife used in the horizontal milling arbor installed, of course, can also be installed in other machine tools are generally used for milling grooves, and steps.
Classification of end mills
end mills distinguished by use of a variety of common types. ① cylindrical cutter: for horizontal milling machining plane. Distributed in the milling cutter circle, press the tooth is divided into two kinds of spur and helical teeth. Divided by the number of teeth of two coarse teeth and fine teeth. Cutter helical gear teeth less coarse, knife-toothed, high strength, chip space, suitable for rough; a fine-tooth milling cutter for finishing. ② face milling cutter: Used vertical milling machine, end milling machine or, gantry milling machine, the processing plane, the circumference of face and teeth are knives, there are coarse and fine teeth tooth points. The structure of the overall style, inlaid teeth and indexable type 3. ③ cutter: grooves and step surface for processing, etc., in the circular cutter and the side surface, the work can not be along the axial feed. When the cutter on the end through the center when the teeth can be axial feed. ④ and face milling cutters: for processing a variety of grooves and step surface, its surface and the circumference of both sides of knife teeth. ⑤ Angle cutters: milling at an angle to the groove, a single angle and double angle cutters two. ⑥ saws: cut off the workpiece for machining deep grooves and whose circumference there are more knife teeth. In order to reduce friction when milling, cutter on both sides of 15 '~ 1 ° Vice declination. In addition, keyway milling cutter dovetail slot cutters and a variety of T-shaped cutter and so on. end mills is structured into 4. ① integral: cutter body and cutter into one. ② overall welding gear: Carbide cutter or other wear-resistant tool material, and brazing the cutter body. ③ inlaid teeth: a mechanical clamping cutter method of fastening the knife body. This can be for the whole cutter head tool material, tool material can also be the head welding. Head mounted on the cutter blade grinding body grinding style called the body; head in the fixture as a separate grinding of the grinding type in vitro. ④ indexable type: This structure has been widely used for face milling, end mills and face milling cutters and so on.
