vertical milling machine cutter
The main cutting edge of milling cutter is on a cylindrical surface, end surface of the cutting edge is vice blade. Can’t go along with the axis of the milling cutter When operation. In accordance with the provisions of the national standard: vertical milling cutter diameter is 2-50 mm, can be divided into coarse and fine teeth . Straight shank diameter range Diameter 2-20, taper shank. 14-50 range for
Standard mills have fine and coarse teeth . 3~4coarse teeth cutter, spiral angle is larger; 5~8 teeth cutter , spiral angle is the smaller. The cutting part of the materials is high speed steel, shank is 45 steel .
There are many shapes of cutters, milling machines and CNC milling machine. On common groove and straight profile, the boring and milling machining center work cavity, core, surface shape / silhouette.
Milling generally divided into:
1. Flat cutter, fine-milling or roughing, milling grooves, removing a lot of rough, a small area of the horizontal plane or contour finishing;
2. Ball mill, for surface finishing and semi-finishing; knife could face a steep fine milling / straight wall of the small chamfer.
3. chamfered flat end mill, roughing do remove a lot of blanks, but also fine finishing flat surface (relative to the steep surface) small chamfer.
4. Molding cutter, including chamfering, T-shaped cutter or knife called a drum-type, tooth type knife, the R knife.
5. Chamfering, chamfering chamfering shape and the same shape, and is divided into milling round beveled chamfer cutter.
6. T type knife can be milled T-slot;
7. Tooth cutter, milling a variety of tooth, such as gears.
8. Bark knife cutter for rough cutting of aluminum-copper alloy designed for fast processing.
There are two common cutter Material: high-speed steel, carbide. The latter with high hardness, cutting ability, can improve the speed and feed rate, improve productivity, so the knife is not obvious, and difficult to machine materials processing stainless steel / titanium alloy, but higher costs, but also in the rapidly alternating cutting force under the circumstances Duandao easy.
