Abstract
The utility model relates to an end surface finish turning cutter with high surface smoothness and higher shape tolerance precision, which comprises a cutter body and a cutter blade, wherein the cutter blade is connected with the cutter body and is fixed through cutter blade screws in a cutter blade groove arranged at the front end side surface of the cutter body, and the cutting edge of the cutter blade is a circular arc with the radius between 50mm and 150mm. Because the cutting edge of the cutter blade is the circular arc with the radius between 50mm and 150mm, the circular arc has large radius, the cutting edge and a processed object form linear contact, the surface unevenness on an enveloping surface is small, so better surface smoothness can be obtained. After the surface is processed by the inner hole finish turning cutter, the surface roughness can reach Ra 0.8 to Ra1.6, the inner hole straightness and circular runout can reach 0.008mm, in addition, the cutter tool has long service life and high processing efficiency, and the work intensity is low.
Description
Technical field
The utility model is and the matched lathe tool of Digit Control Machine Tool, especially for surface smoothness height, the higher endoporus finishing tool of form tolerance precision.
Background technology
Lathe tool is a kind of cutter of metal cutting processing extensive use, can be used to processing excircles, endoporus, end face, screw thread, grooving, chamfering, cut-out etc., and generally speaking, lathe tool is used in cutter and does not change a job on the lathe of part rotation.Hole workpiece processing is adopted the solder type cutter, problems such as utilization rate is low, flexibility, poor practicability that it exists often in solving.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of long service life of cutter is provided, machining accuracy height, the endoporus finishing tool that labour intensity is low.
Solution of the present utility model is: a kind of endoporus finishing tool, comprise cutter hub and the blade that is installed on the cutter hub, it is characterized in that blade is fixed on by the blade screw in the insert groove of cutter hub front end side, the blade cut sword is that a radius is the circular arc of 50mm-150mm.
During its work, workpiece rotates, and lathe tool is the painstaking degree of depth (warp-wise feeding) to machined surface feeding certain distance; The depth of cut is about 0.01-0.05mm; Object to be processed and is rotatablely moved, and the further axial feeding of cutter hub is about 0.5-1.5mm/r, and then along the object to be processed surface translation, thereby metal is reserved in excision, reaches the endoporus finish turning.Because the blade cut sword is that a radius is the circular arc of 50mm-150mm, arc radius is big, and cutting edge forms line with object to be processed and contacts, and the surface irregularity on its formed enveloping surface is very little, so can obtain surface smoothness preferably.
Can make blade be installed on the cutter hub anterior angle that the back forms 10 °-30 ° in the solution of the present utility model, promptly blade be installed in back blade on the cutter hub cutting edge as the summit, its back angle that forms with horizontal plane that tilts gradually is an anterior angle.Its effect is to prevent that the part beyond the blade cut sword from contacting with object to be processed, thereby influences machining accuracy.
Form 6 °-11 ° relief angle at front end after can making blade be installed on the cutter hub in the solution of the present utility model, the cutting edge of blade was as the summit after promptly blade was installed on the cutter hub, and blade and cutter hub tilt and the angle of vertical plane formation is a relief angle.Its effect is to avoid the blade of vertical direction to contact with object to be processed with cutter hub, thereby influences machining accuracy.
Advantage of the present utility model: because the blade cut sword is that a radius is the circular arc of 50mm-150mm, arc radius is big, cutting edge forms line with object to be processed and contacts, and the surface irregularity on its formed enveloping surface is very little, so can obtain surface smoothness preferably.The utility model can reach Ra0.8-Ra1.6 to Surface Machining rear surface roughness, and endoporus linearity and circle are beated and can be reached 0.008mm, and the long service life of cutter, the working (machining) efficiency height, and labour intensity is low.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
The utility model embodiment as shown in Figure 1, a kind of endoporus finishing tool is made of cutter hub 1 and the blade 2 that is installed on the cutter hub 1, blade 2 is fixed on by blade screw 3 in the insert groove of cutter hub 1 front end side, and blade 2 cutting edges are that a radius is the circular arc of 50mm-150mm; After being installed on the cutter hub 1, blade 2 forms 10 °-30 ° anterior angle, blade 2 both upper ends thereof all have cutting edge, the cutting edge back tilts gradually and horizontal plane all forms the β angle, it is that changeable blade 2 directions were used again after an end cutting edge was damaged that blade 2 both upper ends thereof all have the cutting edge purpose, need not change blade 2, to save blade, raise the efficiency; Blade 2 is installed in the back relief angle α angle that forms 5 °-10 ° at front end on the cutter hub 1.
Claims (3)
