Combined forming cutter

Abstract

The combined forming cutter specially for metal cutting lathe includes cutter comprising cutting section and reinforced tail section and elastic fixture. The cutter is formed wholly, needs no grinding when used,and has long service life. The cutter may be manufactured in different specification for lathe operator to select.

Description

Technical field [0001] The invention relates to the manufacture of a shaped cutting tool for a metal cutting lathe. Background technique [0002] The basic shape of the most commonly used cutting tool for existing metal cutting lathes is a thin sheet shape and long, with a large front end and a small rear end, with a large upper side and a smaller lower side (as shown in Figure 2), and always requires H 2 greater than H 3 , its basic knife shape constitutes a knife shape that is easy to break, but lathe workers have always manually ground steel blocks on the grinding wheel into a section of knife shape for a long time. The low precision results in a higher rate of tool breakage, which causes more troubles to the lathe work and high overall cost, which greatly limits the production of the lathe. [0003] The natural wear of the cutting knife during use causes the rake angle V to change quickly and the wear segment S appears, and gradually expands, due to the longitudinal an...

Problems solved by technology

[0005] U.S. Patent US2391133 discloses a cutting tool with alternately welded cutter bodies. Although it does not require a sharpening type, it is limited by the large diameter of the workpiece and the depth of the grooving when used, so it cannot cut larger diameter workpieces and deep grooves, and only Can cut brittle materials
