Description
Technical field
The present invention relates to grinding field, specially a kind of grinding processing method.
Background technology
Grinding processing method originally：Connect emery wheel first with the set incision feed speed close to used in workpiece
Nearly workpiece, in one section of preset time after emery wheel contacts workpiece, ratio is adjusted to by the incision feed speed of emery wheel
Close to the low surface grinding and feeding speed of the feed speed used in workpiece, so-called casting skin grinding is carried out.Set
Feed speed will be cut after time and is adjusted to higher basic grinding incision feeding from above-mentioned surface grinding and feeding speed
Speed.
But, clamping deformation, the machined surface of the workpiece of quenching distortion are produced when being processed to the last stage and is ground
During processing, the contact between this machined surface and emery wheel is discontinuous and shows periodically (typically with the rotation of workpiece
Cycle phase is same), therefore so-called wheel vibration phenomenon is also easy to produce, may be right if now incision feed speed is very big
Emery wheel produces very macrolesion.
Because the flatness of the machined surface of workpiece differs greatly, in order to prevent the damage to emery wheel conscientiously, in grinding
The time of above-mentioned surface grinding must be increased in method.That is, very poor due to there is processing surface evenness
Workpiece, the set surface grinding time must long enough.But, this way is for the preferable work of surface smoothness
Part or the workpiece that need not natively set the longer surface grinding time, also consume many process times.
