Description
Technical field
The present invention relates to lathe parts manufacturing process, more particularly to a kind of automatic lathe spindle processing technique.
Background technology
Main shaft is the important component of lathe, and for automatic lathe, turnery processing precision depends greatly on master
The precision of axle system, and the precision of axis system is by the geometric accuracy of axis system, static state and dynamic rate and the shadow of hot property
It rings.Therefore, how to improve the precision of axis system in lathe setting is the key that design of lathe, and lathe spindle rotating accuracy is
One of main precision controlling index of lathe directly affects the machining accuracy and disc roughness of part to be processed.Lathe master
The manufacturing process of axis has crucial effect to the quality of main shaft, how to advanced optimize lathe spindle manufacturing process, is to improve lathe
Workpiece processing quality, the important channel for ensureing part qualification rate.
Invention content
There is crucial effect to the quality of main shaft for the manufacturing process of above-mentioned machine tool chief axis, how to advanced optimize lathe master
Axis manufacturing process is to improve lathe workpiece processing quality, ensure the problem of important channel of part qualification rate, the present invention provides
A kind of automatic lathe spindle processing technique.
In view of the above-mentioned problems, a kind of automatic lathe spindle processing technique provided by the invention is reached by following technical essential
To goal of the invention：
A kind of automatic lathe spindle processing technique, including roughing, semifinishing and finishing, which is characterized in that
The roughing includes that blank blanking, forging, normalizing, Double End processing, rough turn outer circle and end face, centre bore add
Work；
The semifinishing includes the heat treatment carried out successively and half finish turning；
The finishing includes local high-frequency quenching, finish turning, the periphery grinding carried out successively；
Blank material is 40Cr, and the forging and normalizing process are that blank is first heated to 1000 DEG C to 1100 DEG C, are protected
Temperature makes blank be quenched after being no less than 1.5h, and the temperature being quenched is reduced to 180 DEG C to 250 DEG C, and heat preservation is no less than 1h；
Repeat the above steps, until slab temperature drops to 150 DEG C to 200 DEG C and obtains rough forging, by rough forging plus
Heat to 600 DEG C of -650 DEG C of heat preservations are no less than 3h, and oil cooling or furnace cooling complete normalizing.
As further improving and supplementing to said program, the invention also includes following additional technical features：
It include chamfering deburring operation in the roughing, semifinishing and finishing.
The centre bore drills to drill including isometrical blind hole carries out taper hole turning with subsequent on the basis of blind hole.
The high-frequency quenching be using 60KHz-80KHz quenching frequency, and high-frequency quenching be subsequently additionally provided with 150 DEG C-
180 DEG C of tempering step.
The invention has the advantages that：
1, automatic lathe spindle processing technique provided by the invention passes through the roughing, semifinishing and finishing of setting
Three big steps effectively reduce the cutting output for accurate size control cutting in main shaft manufacturing process, are conducive to improve main shaft
Processing efficiency.
2, by the roughing of setting, semifinishing and three big steps of finishing and rational process control parameter is chosen,
Obtained main shaft hardness can arrive HRC55, and toughness is good, and high-frequency quenching effectively improves the wearability of main shaft disc, above
It is arranged and the main shaft obtained by this method is enable to keep its dimensional stability for a long time, is conducive to the machining accuracy of lathe.
