The so-called lack of precision of the CNC cutting machine is that the previous accuracy cannot be achieved in use, such as the cutting circle is not round, and the cutting line is not straight. Many people first see portable distortion as the result of stepping motor step loss. Although stepping motor step loss may exist, it generally does not happen. It is generally new customers who appear to be distorted in accuracy of portable CNC cutting machines, and use it for more than one month. What is going on?
The power of the portable CNC cutting machine is very small. Normal plane cutting relies on two 24V stepper motors to provide power. Therefore, the power is very small, and the trajectory change will occur when an external force is received. The cleanliness and lubricity of the X-axis and Y-axis are directly related. When the directions of these two tracks are dirty or there are foreign objects, the phenomenon of cutting accuracy will be distorted.
Although some users have eased the distortion after adding lubricating oil, the equipment is not as accurate as when it was bought back. This is ultimately due to the lubrication of the track. In the track or on the gears, there is some greasy or foreign objects Causes accuracy to be affected. The correct way is to fill the track with lubricant. Use both hands to hold the electrode to do the same movement, so as to grind away the foreign objects seen in the gear and rack.
