Tungsten Carbide Scale End Mill

Tungsten carbide scale end mill include milling cutter and milling shank two parts, the main feature is the cutting edge milling cutter portion is composed of left and right-handed helical groove symmetrical cross cutting units constituting, left more than two helical grooves than the right spiral groove; main cutting edge of each cutting unit length is made 0.05 ~ 0.1mm, cutting flank along the trailing edge made of a cylindrical surface width 0 ~ 0.01mm; front cutting edge angle is made 10°~ 15°, the rake face on the cross-section method is linear; after the cutting edge angle is made 20°~ 25 °; spiral deep sipes made tool diameter of 7 to 8%.

In order not to appear delamination or burrs phenomenon but also to improve processing efficiency, for composite milling should be used in conjunction milling processing methods. Therefore, we have proposed a design of solid carbide "scale" cutter. The tool consists of two parts blade portion and a shank composed of this kind of cutting edge milling cutter portion on the scale of many cutting unit consists of alternating left and right rotation symmetrical spiral groove formed composition, more right-handed than left-handed spiral groove 2 around the spiral groove helix angle were 30°; the main cutting edge of each cutting unit is only 0.05 ~ 0.1mm long spiral blade; spiral blade angle is made before the 10°~ 15°, in cross-section on the law and rake a straight line; deep spiral groove cutter tool diameter 7% to 8%; after the helix angle of the blade made of 20°~ 25°; after helical flank formed along the cylindrical surface width 0 ~ 0.01mm.

Tungsten Carbide Staggered Edge End Mill

Tungsten carbide staggered edge end mill is a kind of new special cutter for fiber composite materials, its cutting edge is divided into upper and lower parts, the workpiece material should be on the middle area under the producing process. Due to the use of a proximal portion of the cutting edge blade right-handed, left-handed blade near the handle of the staggered design, the lower end of the right-handed cutting edge end mill for milling under the surface, under the surface by the upward cutting force; standing upper cutter L on the cutting edge for milling the surface, on the surface by the downward cutting force. Thus, the material, the lower surface of the fibrous layer are completely cut off easily, effectively preventing the upper and lower surfaces of the workpiece tear, burrs and other processing defects.

Spiral staggered around edge carbide end mill is mainly used for paper trimming and milling aramid honeycomb sandwich composites. Since the cutting edge of the tool is symmetrical about a staggered spiral, and helical cutting edge around the junction is always held in the neutral position of the paper and the aramid honeycomb sandwich structure, and therefore, in the trimming process, two surfaces of the sandwich structure cutting force is always toward the center of the sandwich structure, thus avoiding crack, layer or spinning phenomenon.
