Turning and milling CNC lathe why stress relief?

Machine tool teachers in the actual operation of the front feed automatic lathe must release stress. And the more precise processing of the machine tool the more attention should be paid to the release of stress. Then, why release stress? If the release to release how long? How to release the stress is good and a series of issues related to machine tool stress, do not worry, and with the content of the article gradually seem.

First, what is stress?

Machine tools must release the full name of the stress is mechanical equipment stress, is the bed and other prefabricated components in the thermoforming production process. Because economic CNC machine tools must be machined with precision to μm or even nanometer, this type of internal stress formed in the casting of the deformation provided by the deviation can not be carried out, so the flat spindle lathe SK32 must release the stress.

Simply put is the machine tool related prefabricated components in the heat treatment will cause stress, such stress will cause prefabricated components to cause certain deformation, and such deformation will directly affect the precision of the machine tool, so the more precision machining of the machine tool the more must be released to ensure the precision and reliability of the machine tool.

Second, how long does it take to release the stress of the machine tool?

Non-standard customized CNC lathe stress release generally choose the way of static, firmly believe that we all know. Heard in the past, some machine tool manufacturers in order to better adequate release of stress will be casting parts sunk into the seabed or buried into the ground. This kind of point of view can not be examined, only for the reference of the guys. Then economic CNC machine tool stress to release how long?

Stress release according to the metal structure of the different, and then fully consider the volume, look and other elements, probably must be many months to two years vary. It must be noted that the conditions of stress release should be taken into account according to the details of the prefabricated components. It is not the case that good practical results can be obtained outdoors or in some extreme natural environment. Naturally, with the development of new technologies, there are more and more ways to release stress and the duration is becoming shorter and shorter.

How to release stress?

As mentioned above, static stress relieving is one of the methods of stress relieving, but these methods are being used less and less today. For no other reason, the time required to release the stress of static is too long, for machine tool manufacturers is too expensive.

With the development of new technologies, there are more and more ways to release stress on economical CNC machine tools, and the duration is becoming shorter and shorter. In talking about the actual release of stress before the way to emphasize in particular, stress release is generally completed before assembly, assembly after the straw is generally in the fall of the machine after the static 10 to 20 days up and down, the actual according to the different manufacturers to do it on the indication.
