Causes Of Large Errors in The Process Of Deep Hole Machining

The design value of the outer diameter of the reamer is too large or the cutting edge of the reaming has burrs; the cutting speed is too high; the feed rate is improper or the machining allowance is too large; the main deflection angle of the reamer is too large; the reamer is bent; Adhering to chip tumor; when sharpening, the reaming cutting edge swing difference is out of tolerance; the cutting fluid selection is not suitable; the oil on the surface of the taper shank is not cleaned or the taper surface is bumped when installing the reamer; the flat tail of the taper shank is installed in an offset position The rear taper shank of the machine tool spindle interferes with the cone; the spindle is bent or the spindle bearing is too loose or damaged; the reamer is not flexible; the axis is different from the workpiece and the force of the two hands is uneven when the hand reams, which makes the reamer shake left and right.
