Embodiment Construction
[0011] Such as figure 1 As shown, the two-edged tungsten steel end knife includes a handle 1, a knife neck 2 and a knife head 3. Two cutting edges are arranged on the cutting end surface of the knife head. The length l of the knife head is 12mm-15mm, usually The diameter d of the cutter head is 1.5mm-0.8mm, usually 3mm, the knife neck is set to be chamfered, the angle of the chamfer is 60°, and the helix angle of the chip flute is set to 30°.
[0012] The total length L of the end knife is 30mm-50mm, usually 50mm.
[0013] The diameter D of the handle of a knife is 6mm.
[0014] The cutter head is configured as a cutting part 3a and a connecting part 3b, and the length l' of the cutting part is 3mm-6mm, usually 5mm.

Abstract
The invention belongs to the field of cutting mills, and particularly relates to a two-blade tungsten steel end mill. The two-blade tungsten steel end mill comprises a mill handle, a mill neck and a mill head, wherein the cutting end surface of the end part of the mill head is provided with two cutting blades; the mill head has the length of 12mm-15mm, and has the diameter of 1.5mm-0.8mm; the mill neck is arranged to be a chamfer; the angle of the chamfer is 60 degrees; the spiral angle of a chip discharge groove is arranged to be of 30 degrees. The two-blade tungsten steel end mill provided by the invention has the advantages that the two-blade tungsten steel end mill is simple in structure, is easy to machine, can directly mill the surfaces of small products, and can improve the machining efficiency.
Description
technical field [0001] The invention belongs to the field of cutting tools, in particular to a two-edged tungsten steel end knife. Background technique [0002] The end cutter is also a face milling cutter, which is also an end milling cutter. It is a tool commonly used in milling machines to process planes. (also known as a single milling cutter) can be welded on the cutter head, and can also be fixed on the cutter head by assembly. According to the milling principle, the denser the teeth of the end mill, the more stable the cutting, and a larger feed rate can be selected. efficient. But on small operating surfaces, large face milling cutters cannot be used, such as the milling of notebook casings and the processing of small products. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present invention proposes a two-edged tungsten steel end knife capable of processing small products. [0004] The invention provides t...
