Does low DMG spindle temperature affect accuracy?

Look at the temperature in what range, if the room temperature up and down the amplitude is not large, it will basically not have any accuracy effect, if it is too cold, to dozens of degrees below zero or overheating more than 100 degrees, then the spindle will definitely have a little accuracy impact. However, as long as the cooling is in place, there is no problem with the spindle even if there is a slight temperature fluctuation.

Does DMG curse low temperature affect accuracy? This will definitely affect the accuracy, and there will definitely be some factors.

There is an impact, but because the temperature change is relatively small compared to the temperature change caused by other reasons, especially the temperature change is uniform relative to all parts of the machine tool, so the impact is not large.

The machine tool is affected by the change of the ambient temperature of the workshop, the heating of the motor and the friction heating of the mechanical movement, the cutting heat and the cooling medium, resulting in the uneven temperature rise of each part of the machine tool, resulting in the change of the shape accuracy and machining accuracy of the machine tool. The temperature rise makes the temperature of each part of the parts change with time, so that the machine tool loses the existing adjustment accuracy, thereby affecting the size of the workpiece to be processed, and at the same time, the temperature rise also makes the bearing clearance change, and then affects the machining accuracy. On the other hand, the temperature increase makes the temperature distribution uneven, causing the mutual position relationship between the parts or parts of the parts to change, resulting in the displacement or distortion of the parts.

If the temperature of the DMG spindle is low, it will definitely affect the progress and the accuracy of the product.

Does the low temperature of the TM owner affect Jingzhou, of course, it affects him and the influence.

The low temperature of this spindle is indeed a requirement that affects accuracy.

The German DMG machining center spindle used to use the German Kessler motor spindle, which led to the high repair rate of the aftermarket electric spindle. According to the German Machine Tool Association, the German DMG Group is now negotiating an OEM agreement with the German Rex Group for the entire machining center spindle. Whether or not a cooperation has been reached may be a trade secret that is not known.

Why is the DMG machine spindle broken again?? DMG is equipped with German Kessler electric spindles, it seems that Kessler Kessler electric spindles are really rags as the outside world says, we are German GMN, use GMN electric spindles to ensure that you will not break, because we are much better than Kessler Kessler's rags.

It depends on the model, power and accuracy of the spindle itself, as well as what kind of parts are damaged, ranging from thousands to tens of thousands.

The tool rotates and requires a torque, and the main part of the torque is the flange keyway. The main function of the shank taper is to hold it in place and to provide a certain amount of torque. If you apply oil to the taper shank, there will be a layer of oil film between the taper of the shank and the taper of the spindle of the machine tool, and the good contact between the shank and the spindle will not be achieved, which will seriously affect the stability of the tool.

One of the requirements before the tool is put on the machine is to keep it clean, free of stains, and of course oil. Otherwise, the workpiece you process will be basically inaccurate.
