Abstract
The invention relates to a lathe tool with a chip breaking member. The lathe tool includes a tool body; an installation groove is formed in an end of the tool body; a tool bit is arranged in the installation groove; a clamping arm is arranged on the tool body; the clamping arm is fixed on the tool body through a bolt; an end of the clamping arm is positioned above the tool bit; and the chip breaking member having a recessed arc surface at the front end thereof is arranged between the tool bit and the clamping arm, and the end of the clamping arm presses the chip breaking member. The clamping arm is arranged on the tool body, the clamping arm is fixed on the tool body through the bolt, the end of the clamping arm is positioned above the tool bit, the clamping arm can clamp the chip breaking member, the chip breaking member and the tool bit are pressed together, and the front end of the chip breaking member is the recessed arc surface, and in this way, resistance is increased suddenly while a cutting member meets the arc surface, the cutting member is broken under the impact force, and a chip breaking effect can be achieved. Raised edges are arranged on the recessed arc surface of the chip breaking member, and the raised edges can further enhance friction force between the raised edges and the cutting member, and then the cutting member is easy to break.
Description
Technical field
The present invention relates to machining equipment field, and in particular to a kind of lathe tool with chip breaking part.
Background technology
Lathe tool species and purposes lathe tool are a kind of most widely used single-point tools.Lathe tool is used for various lathes, processing excircles, endoporus, end face, screw thread, recessing etc..Lathe tool can be divided into overall lathe tool, brazed carbide turning tool, mechanically-clamped turning tool, indexable turning tool and shaped profile turning cutter by structure.The application of wherein indexable turning tool is increasingly extensive, and in lathe tool, proportion gradually increases.
The cutting tip of lathe tool is by knife face and minor flank after main cutting edge, front cutting edge, rake face, master, nose angle composition.The combination of the cutting tip and shank of lathe tool mainly has monoblock type, welding type, insert and welding-insert.
Lathe is when steel material workpiece is cut, often or produce chip without stop, metal cutting scraps can not disconnect automatically, repeatedly occur so as to cause to twine bits, problem of forging a knife, affect production efficiency current, for iron filings without stop produced in lathe process, general processing method is to arrange special librarian use cleek instrument, produced iron filings are dragged into disconnected from above workpiece regularly, so, there is less efficient, relatively costly defect, substantial amounts of manpower and materials are wasted not only, also the different degrees of safety that have impact on production efficiency and operator.
