Common lathe covers kind of work general by inside aperture, outside the composition such as round, plane, in turning process, spend to make sure the appearance of workpiece and place are special and requirement of exterior surface roughness, should choose the logical way that hold clip and accurate turning method. Common lathe is when workpiece of turning thin wall, still should notice the work that because clamping force is caused,shuns is out of shape. The introduction makes sure coaxial spends the method with verticality below. 1. Common lathe is installed in turning treatment is finished to be in in clip odd a small lot production is medium, can install clip to end the treatment of all or major appearance of workpiece last time in chuck or flower disc. This kind of method does not have fixed position error, if lathe precision is taller, can win taller form precision. But when using turning of this kind of method, need often changes tool carrier, dimension masters harder, cutting dosage also needs to often be changed. 2. Common lathe locates with Kong Wei fiducial when using the axle sleeve with arbor medium or small turning, belt annulus, work such as gear, can use the Kong Wei that already had machined commonly fixed position is standard, the method that uses arbor fixed position undertakes turning. Commonly used arbor has following two kinds. (Arbor of substance of arbor of 1) banquet body has small taper arbor and columnar arbor two kinds. The taper C=(l of small taper arbor: 1000) , (1: 5000) , the characteristic of this kind of arbor is to make precision of simple T centering tall, but axial cannot locate, bear cutting force is small, assemble and unassemble not quite convenient. When placing workpiece with outfit of rank stage arbor, the cylinder of arbor maintains lesser clearance fit between part and workpiece aperture, workpiece relies on nut impaction. Its characteristic is OK hold clip many workpiece, if use mouth gasket, assemble and unassemble workpiece is more convenient, but centering precision is inferior, can assure only. . The coaxial that 02mm controls is spent. (2) bilges force arbor bilges force arbor relies on what material flexibility is out of shape place arises to bilge force will secure work. Bilge the round cone angle of force arbor had better is 30. Or so, thick J of wall of the smallest part, 6mm. Bilge to make force is even, groove but make it trisect. Use for a long time bilge usable bedspring steeliness becomes force arbor. Bilge force arbor assembles and unassemble convenient, centering precision is tall, reason application is wide. 3. The circle is fixed position beyond common lathe fiducial the circle outside using soft card claw to should be machined is bigger, inside aperture lesser, length is shorter cover kind of part, and the circle is beyond workpiece fiducial when assuring positional precision, soft outfit blocking claw applies to place workpiece commonly on lathe. Soft card claw is to use become without quenched 45 steeliness. When using, will soft claw loads chuck inside, become soft ungual vehicle the circular arc measure of a need next. When car soft claw, to eliminate gap, should be inside card claw (or outside blocking claw) the fixed position that puts one proper diameter is columnar (or cirque) . When the circle outside should holding work with soft ungual clip (or say ungual) , ; should use soft ungual clip inside locate cylinder should be put in card claw when holding work (or say to turn over claw) , fixed position annulus should be put outside card claw. When placing workpiece with soft ungual outfit, because soft claw is,go up in itself lathe turning figuration, because this can ensure,install clip precision; Next, when installing clip to already machined the surface or soft metal, not easy clip hurts workpiece surface. 4. When common lathe places workpiece of workpiece car thin wall with suit rising a mouth, because the cut sex of workpiece is poor, easy below the action of clamping force generation is out of shape, be out of shape to prevent or reduce what Bao Bi covers kind of work, often use mouth suit to place workpiece. Because the mouth is covered,accumulate with the interface of workpiece big, clamping force distributings to go up in the circle outside workpiece equably, can reduce clamp to be out of shape so, can achieve taller coaxial to spend at the same time. When using, first seam a brief outfit to be in outside workpiece on the circle, next another removes clamp to go up from centering chuck in 3 claw. 5. Common lathe places workpiece with flower disc outfit bigger to the diameter, the Baobi with dimension precision and higher demand of appearance position precision disc workpiece, can install clip to be on flower disc turning, use method of end panel impaction, workpiece arises not easily be out of shape. 6. Common lathe places workpiece basis to machine the characteristic of the spare parts to design the special fixture that make with special fixture outfit, the Kong Zhong that workpiece loads clamping apparatus body (the circle outside using locates) , with locknut workpiece axial clamp, can prevent workpiece to be out of shape.
