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.
