The processing technology of the precision parts of various types of precision shaft line

by:Xavier      2020-06-30

all kinds of precision metal shaft parts are the main surface of the journal of the cylindrical surface, the inner hole of hollow shaft precision general requirements is not high, and the precision metal shaft screw, spline, slotting, etc on the surface of the secondary has a high accuracy requirement. As a result, the shaft parts processing technology route is mainly consider the processing sequence of cylindrical, and on the surface of the secondary processing of reasonably. Here by we want to introduce to you, different precision, different materials commonly used in the production of all kinds of precision metal shaft parts processing craft route:

( 1) General carburizing steel precision metal shaft parts processing technology: preparation - Forging - Are fire - Center hole - Coarse car - Half essence cars, car - Carburizing ( Or carbonitriding) - - - - - - Quenching and low temperature tempering - Coarse grinding - - the secondary surface processing Fine grinding.

( 2) General accuracy of quenched and tempered steel precision metal shaft processing craft route: preparation - Forging - Is a fire, Annealing) - - - - - - Center hole - Coarse car - Quenched and tempered - Half essence cars, car - Surface quenching and tempering Coarse grinding - - the secondary surface processing Fine grinding.

( 3) Precision nitrided steel shaft parts processing craft route: preparation - Forging - Is a fire, Annealing) - - - - - - Center hole - Coarse car - Quality - Half essence cars, car - Low temperature aging - Coarse grinding - - nitriding treatment - the secondary surface processing Fine grinding - Light grinding.

( 4) Overall quenching precision metal shaft parts processing craft route: preparation - Forging - Is a fire, Annealing) - - - - - - Center hole - Coarse car - Quenched and tempered - Semi finished car, car - - the secondary surface processing The overall quenching - Coarse grinding - Low temperature aging - Fine grinding.

general precision metal shaft parts, the final process using fine grinding is sufficient to ensure the quality of machining. Precision shaft parts, in addition to finishing, still should arrange finishing processing. For shaft parts in addition to the overall quenching, its fine car process according to the specific situation is different, arrangement before quenching heat treatment, or arrangement after quenching heat treatment, the secondary surface before processing.

it should be noted that after quenching parts, can't use general knife, shaft parts are the main surface of the journal of the cylindrical surface, the inner hole of hollow shaft precision general requirements is not high, and the thread on the precision spindle, spline, slotting, etc on the surface of the secondary has a high accuracy requirement. As a result, the shaft parts processing technology route is mainly consider the processing sequence of cylindrical, and on the surface of the secondary processing of reasonably.
