Abstract
The utility model discloses a cylindrical locating type polymerize crystal diamond turning tool blade, which comprises a tool bit and a cutter body. The tool bit and the cutter body are combined in a vacuum silver welding mode. The tool bit is made of polymerize crystal diamond clad sheets, the cutter body is made of hard alloy, and an arc is disposed at the position of a cutting edge of the tool bit. The tool bit is a triangular body, and the cutter body is a cylindrical body. By disposing the arc at the position of the cutting edge of the tool bit, the cutting edge is in arc transition, the cylindrical locating type polymerize crystal diamond turning tool blade changes the contact mode of a cutting edge of an existing tool and workpieces, and the previous line contact is changed to the transition contact from point to line. Therefore, cutting resistance of the tool is greatly reduced, and machining efficiency and surface quality of workpieces are improved. The arc is disposed at the position of the cutting edge of the tool bit, a wiper is formed simultaneously, and the angle between the wiper and the reference edge is 15 DEG C to 25 DEG C so as to ensure machining noninterference and good machining effect.
Description
Technical field
The utility model relates to a kind of lathe tool that is used for turning processing, particularly relates to a kind of cylinder locate mode PCD Turning Tool sheet.
Background technology
The structure that is used for the lathe tool of processing key parts directly influences the precision of machining.At present; The cutting tip of lathe tool mainly is composite polycrystal-diamond (or polycrystalline cubic boron nitride composite sheet); This kind composite sheet is formed through the HTHP compacting by polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer, and composite sheet is in the same place through solder bond with cutter hub.In the existing lathe tool structure, the cutter head place does not often have transition, in process, has strengthened the cutting resistance of cutter, thereby influences the surface quality of working (machining) efficiency and workpiece.
Summary of the invention
The purpose of the utility model is to being used for the bigger defective of cutting resistance that turning processing turning insert exists at present, a kind of cylinder locate mode PCD Turning Tool sheet being provided.Adopt the utility model cutter to carry out turning processing, in working angles, greatly reduce the cutting resistance of cutter, thereby improved the surface quality of working (machining) efficiency and workpiece.
In order to address the above problem, the technical scheme that the utility model adopts is:
The utility model provides a kind of cylinder locate mode PCD Turning Tool sheet, comprises cutter head and cutter hub, and wherein: said cutter head cutting edge place is provided with circular arc.
According to above-mentioned cylinder locate mode PCD Turning Tool sheet, the radius of said circular arc is 0.2～1.5mm.
According to above-mentioned cylinder locate mode PCD Turning Tool sheet, said cutter head is a trigone; Said cutter hub is a cylinder.
According to above-mentioned cylinder locate mode PCD Turning Tool sheet, said cutter head and cutter hub adopt vacuum silver soldering mode to combine.
According to above-mentioned cylinder locate mode PCD Turning Tool sheet, the material that said cutter head adopts is a composite polycrystal-diamond; The material that said cutter hub adopts is a carbide alloy.
The welding of the utility model cutter head and cutter hub: process a cylindrical deep hole in the bottom at triangle cutter head center, the cutter hub cylinder adopts the mode of vacuum silver soldering, is welded on the cutter head bottom through cylindrical deep hole, passes through Sharpening a knife blade again, the angle grinding-shaping.
The clamping process of the utility model cylinder locate mode PCD Turning Tool sheet: the lathe tool cutter is that benchmark is put in the jig circular hole with the cylindrical body, the matched in clearance location, and the cutter upper surface is fixed with pressing plate.
The positive beneficial effect of the utility model:
1, the utility model cylinder locate mode PCD Turning Tool sheet is provided with circular arc at cutter head cutting edge place (radius of circular arc is 0.2～1.5mm); The cutting edge arc transition; Changed the way of contact of existing Tool in Cutting sword and workpiece; Become by the transition contact of putting line by original line contact, greatly reduced the cutting resistance of cutter thus, thereby improved the surface quality of working (machining) efficiency and workpiece.
2, the utility model forms wiper edges simultaneously through being provided with circular arc at cutter head cutting edge place, and wiper edges and true edge angle are 15～25 ℃, does not interfere to guarantee processing, and processing effect is better.
3, the cutter head of the utility model lathe tool adopts polycrystalline diamond, is adding man-hour like this, because the hardness of polycrystalline diamond is high, wearability is good, makes its processed surface smoothness better.
Four, description of drawings:
The front view of Fig. 1 the utility model;
The right view of Fig. 2 the utility model.
