Description
Technical field
The utility model is related to machining tool technical field, and in particular to a kind of lathe tool.
Background technology
Lathe tool is the necessary instrument for completing turnery processing, including billmpse tool, internal lathe-tool, recessing bit, threading tool
The effect of turnery processing is directly affected Deng, the selection of lathe tool, turnery processing includes rough turn processing and finishing processing two parts, smart car
The purpose of processing is to remove allowance for finish, while ensure workpiece size precision and surface roughness, additionally due to smart car
Processing point of a knife position work under bad environment, using frequent, thermal capacity is small, easy to wear, and nose part is got and also can less than effectively lubricating
Abrasion to point of a knife is accelerated, and service life shortens, meanwhile, in finishing processing, when back engagement of the cutting edge is less than 0.05mm, by knife
The influence of the factors such as tool intensity, blade shapes and cutting-tool angle, makes workpiece size precision and surface roughness hardly result in guarantee.
The content of the invention
Regarding to the issue above, the utility model provides a kind of lathe tool, for finishing turning.There is provided by the utility model
Lathe tool can solve the problem that finishing processing back engagement of the cutting edge be less than 0.05mm when, workpiece surface is difficult to cut qualified roughness and size
The problem of precision, while cutting position can be changed, it is to avoid point of a knife cuts, reduces tool wear and number of times of refacing, and improves cutter
Life-span and the uniformity of workpiece size precision.
The utility model be solve the technical scheme that is used of above-mentioned technical problem for：
A kind of lathe tool, including turning cutter body and special-shaped blade, turning cutter body head are provided with blade welding groove, are welded with groove
Special-shaped blade.
The main cutting edge of the special-shaped blade is shaped as R40-50mm circular arcs, and sword 8-10mm long, front cutting edge is shaped as
R40-50mm circular arcs, sword 8-10mm long, tool cutting edge angle is 5 ° -8 °, and auxiliary angle is 5 ° -11 °, and knife face is shaped as R6-R7mm circles after master
Cambered surface, minor flank is shaped as R6.5-R8mm arc surfaces, forms a circular arc rib between knife face and minor flank after master
Side, is used to cut as cutting edge.
Using above-mentioned technical proposal, main cutting edge and front cutting edge are changed to deep camber circular shape, avoid cutting interference
Position, by the change in shape of knife face a and minor flank b after master, by cutting edge change based on after knife face and minor flank intersect
The half round edge c at place, makes cutter and workpiece are more uniformly stressed in working angles, and no matter finishing processing end face, circular arc is bent
Face, back engagement of the cutting edge remains constant during outer round surface, coordinates 5 ° -8 ° of tool cutting edge angle and 5 ° -11 ° of auxiliary angle, can be effective
Ground makes tiny chip-flowing work surface side, it is to avoid fine metal chip-flowing machined surface or rear knife face and work
Between part machined surface, workpiece machined surface is scratched and is destroyed.Therefore, the utility model is by the main cutting to lathe tool
The selection of knife face, minor flank, tool cutting edge angle and auxiliary angle after sword, front cutting edge, master, improves when finishing processing cutting depth is less than
During 0.05mm, the stress of finishing processing and the discharge direction of chip, it is to avoid vibration, squeeze to cut and scratch machined surface etc. with chip
Situation, reduces the difficulty of finishing turning, and the change of Tool in Cutting position and shape in addition, it is possible to increase cutter life subtracts
Few tool changing is refaced number of times.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model；
In figure, 1 is turning cutter body, and 2 is welding groove, and 3 is special-shaped blade.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, including turning cutter body 1, welding groove 2 and special-shaped blade 3, the head of turning cutter body 1 are provided with welding groove
2, special-shaped blade 3 is welded with groove.The main cutting edge R of special-shaped blade 31With front cutting edge R2It is R42mm circular arcs, sword L long1And L2
It is 8.5mm, tool cutting edge angle（j）It is 5 ° -8 °, auxiliary angle（k）It is 5 ° -11 °.
Use process：
By outside diameter DOutwardIt is 45mm, length is the mild steel material clamping of 50mm on numerically controlled lathe, stretches out three-jaw card
Disk 30mm, rough turn processing is carried out using cylindrical roughing tool, by DOutwardIt is finishing for 45mm diameters are machined to 40.02-40.03mm
Turning made allowance 0.02-0.04mm.
By lathe tool clamping described in the utility model on the knife rest of numerically controlled lathe, intersected with minor flank using knife face after master
The circular arc seamed edge c at place is carried out to knife.The diameter of work completed for upper step roughing calculates finishing Cutting parameters.Using master
The circular arc seamed edge c of knife face and minor flank intersection carries out cylindrical finishing turning as cutting edge afterwards, by excircle dimension plus
Work obtains workpiece surface roughness for Ra≤1.6 μm to 40 ± 0.01mm.
