Abstract
The invention relates to the field of machining, in particular to a grinding method for a superfine five-edge reamer. The method comprises the following steps: dismounting a headstock centre and a conical sheath of a machine tool, fixing a screw which is used for driving a chuck to rotate, mounting and fastening the chuck, and then mounting a five-edge positioning sleeve on the machine tool, wherein the five-edge positioning sleeve is driven to rotate when the chuck rotates, and when the five-edge positioning sleeve is pulled by hand, the chuck rotates to a position where the chuck stays at the same angle as the five-edge positioning sleeve; and clamping a workpiece on the chuck, and then starting grinding, wherein the chuck clamps the four-fifths position of a shank of the workpiece, the feeding amount is 0.02-0.03 mm each time, after each feeding, the five faces of the workpiece are all ground, size measurement is performed with a micrometer and testing is carried, then next feeding is performed, and the grinding process is repeated until the workpiece is ground to a qualified size. The method provided by the invention is simple to operate, can guarantee the machining quality and the machining precision, improves the production efficiency, reduces the production cost, and increases the product qualification rate.
Description
Technical field
The present invention relates to field of machining, and in particular to the method for grinding of ultra-fine five square reamer.
Background technology
Reamer has one or more cutters tooth, in order to cut off the rotary cutter of machined hole surface sheet metal, with straight
The rotation finishing tool of sword or helical edges, for reaming or repair hole use, through reamer processing after hole can obtain accurately
Size and dimension.Reamer is used for drilling on ream workpiece（Or reaming）Hole after processing, primarily to improve adding for hole
Work precision, reduces the roughness on its surface, is polish and semi-finished cutter for hole, the general very little of allowance.
The reamer for being used for processing cylindrical hole is the more commonly used.The reamer for being used for processing bellmouth is taper reamer, fewer use.By use
There are hand reamer and chucking reamer from the point of view of situation, chucking reamer can be divided into straight shank reamer and taper-shank reamer again.Handss are then straight
Shank type.Reamer structure major part is made up of working portion and shank.Working portion acts primarily as cutting and calibration function, at calibration
Diameter has back draught.And shank is then used for being clamped by fixture, have staight shank and taper shank point.And the production of reamer directly affects workpiece
Machining accuracy, there is certain difficulty in the processing for five square reamers.
Grinding energy obtains very high machining accuracy and surface roughness.Not only soft material can be processed, such as non-hardened steel, casting
Ferrum etc., and can with the very high material of workhardness, such as the common metal cutter such as hardened steel, hard alloy, high-speed steel be difficult plus
Work, or even the material that can not process, generally, during grinding, cutting depth is less, the metal that can cut off in one stroke
Layer is relatively thin, and the grinding of five square reamers, prior art is used directly and is ground to shaping, and is easily produced in grinding process
Vibration with allow knife phenomenon, before and after causing cutter tooth land, width does not wait land mill cutting edge of a knife or a sword, and the grinding for ultra-fine five square reamer is above-mentioned
Method is not simultaneously applied to.
Content of the invention
In order to solve the above problems, present invention offer is a kind of simple to operate, ensure that crudy and machining accuracy, carries
High efficiency, reduces production cost, improves the method for grinding of ultra-fine five square reamer of conforming product rate.
The method for grinding of ultra-fine five square reamer of the present invention, comprises the following steps：
The first step, machine tool crown point and cone sheath are pulled down, and the screw rod for driving chuck rotation are fixed, chuck for installing, and
And fasten, then by five side's positioning sleeves on the lathe, drive positioning sleeve to rotate when chuck rotate, when pulling positioning with handss
During set, chuck is turned on the position with positioning sleeve equal angular；
Second step, workpiece is installed on chuck, and chuck blocks 4/5 position of workpiece shank, starts grinding, the feeding of each knife
Measure as 0.02mm-0.03mm, and five faces have all been ground by the amount of feeding each time, then using miking size, are entered
Performing check, then second amount of feeding upper slitter is carried out, qualified up to finally size being ground.
Preferably, in second step, grinding is divided into corase grind and refines, and roughly grinds made allowance 0.05mm-0.08mm, and grinding completes one
After secondary, workpiece is detected, circle bounce and the surface roughness of workpiece is detected, is then ground again, to having roughly ground
Refined after becoming, emery wheel repaired, diamond just commutated after edge 3mm ~ 5mm is surmounted, by the smoothing of emery wheel edge or roundlet is repaiied,
And fine grinding is once ground after the completion of being all ground five faces on carrying out every time.
The present invention is simple to operate, ensure that crudy and machining accuracy, improve production efficiency, reduces production cost,
Improve conforming product rate.
Specific embodiment
Embodiment one：The method for grinding of ultra-fine five square reamer of the present invention, comprises the following steps：

And fasten, then by five side's positioning sleeves on the lathe, drive positioning sleeve to rotate when chuck rotate, when pulling positioning with handss
During set, chuck is turned on the position with positioning sleeve equal angular；
Second step, workpiece is installed on chuck, and chuck blocks 4/5 position of workpiece shank, starts grinding, the feeding of each knife
Measure as 0.02mm-0.03mm, and five faces have all been ground by the amount of feeding each time, then using miking size, are entered
Performing check, then second amount of feeding upper slitter is carried out, qualified up to finally size being ground.
Embodiment two：The method for grinding of ultra-fine five square reamer of the present invention, comprises the following steps：
The first step, machine tool crown point and cone sheath are pulled down, and the screw rod for driving chuck rotation are fixed, chuck for installing, and
