Super Feng Electrical: processing lathe guideway high frequency quenching after deformation
Henan Chao?Feng electrical,?committed to?the customer experience,?for customers to solve various?kinds?are easily generated in the?heating?process,?provide a reasonable solution.
The main?reason of?quenching?deformation?of lathe guide rail:
1,?the lathe guide?speed?uneven cooling?in?high-frequency quenching,?lathe guideway?surface quenching,?surface?cooling fast,?while the lower?slower cooling rate,?speed?ofcontraction,?cause the deformation?of lathe guideway?midconcave.
2,?the lathe?guide rail?quenching?deformation?and the size of the?rail?bed?resistance to deformation?stiffness?also has a relationship,?such as?small stiffness,?deformation?is bigger.
3,?rail?quenching?lathe?process,?due to?the?expansion and contraction of?volume change?is not uniform?and microstructure?change,?will?produce the internal stress?of considerable?strength,?when the?stress?exceeds the material,so that the workpiece?deformation.
High Frequency Quenching Rail
How to solve the?problem?of lathe guideway?high frequency quenching after?deformation:
Stress relieving?1,?vibration aging
Between the guideway?surface quenching?process and?grindingprocess?of bed?vibration aging,?vibration aging?is?vibrating device is?fixed on the bed,?the exciting force?to the workpiece?resonance occurs,?the?alternating?motion?of absorbing vibration energy,?so that the?residual forceunleashed,?improve the dimensional stability?of the bed.
2,?the?deformation compensation?technology
On the rail?when planing,?the?two ends of the supporting,intermediate?downward pressure,?make the?bed?deformation,concave down?after processing,?relieve?pressure,?elastic recovery,?so as to control the?guide?concave in the middle.
3,?improve the local?connection?bed?and?track stiffness
When quenching?the?body?fixed on the fixture,?fixture to improve?the ability to resist deformation?by,?when quenching,the?bed?is fixed in a?bending strength of?large?base.
Using the above?method can?prevent the?lathe guide railquenching?deformation,?leading to the?ends of the?hardened layer?all?off,?will not be able to?track?down?the straight,resulting in?lathe guideway?substandard quality,?waste of raw material,?liquid?hardware?becomes thin,?soft spots,?faultsresistance reduce?etc..
Henan Chao?Feng electrical,?devoted to research and development of?high frequency furnace?industry,?provides?thehigh frequency furnace?fault handling?service,?customers?get the maximum protection.
