Applications of the Rotary Axis for Metal Marking

This article analyzes the key role that the rotary axis plays in marking curved surfaces, and discusses how to improve the precision and efficiency of marking curved surfaces using rotary axis technology.The content covers the principle of rotating axis marking, applicable scenarios, and operational skills, providing a practical solution for the metal processing industry.

Why is the axis of rotation so important in marking a curved surface?

Many customers encounter this problem: When marking curved metal surfaces, the marks are often crooked or of uneven depth.In fact, there is a close relationship between this and the traditional way of marking.Unlike a flat surface, even a slight curve can cause the laser beam to lose its focus. This is where the rotary axis comes in. It can rotate the workpiece at a constant speed, keeping the laser head at an optimal distance for marking, as if it were "spreading" the curved surface out into a plane.

What situations is the rotary axis marking suitable for?

Special metal parts.

For example, the curved surfaces of automobile engine parts or medical equipment are not easily processed on conventional machines.The axis can be combined with a three-dimensional positioning system to easily meet the needs of marking cylindrical, spherical or even complex curved surfaces.

High precision industrial marking.

The QR codes and serial numbers used on aerospace components, for example, must be extremely clear and durable.The rotating axis spins at a constant speed to prevent vibration, and in combination with pulse laser technology, can achieve a marking effect with micron-level precision.

These are the main things to consider when selecting equipment.

Axis stability is key.

Don't just look at the RPM range on the spec sheet. In actual use, lightly touch the axis of rotation. If you feel a noticeable vibration or heat, this equipment is likely to have problems after a while.A good spindle runs almost silently and can work continuously for several hours without losing stability.

Software compatibility ignores gender.

Some of the machines need special software to control their spinning shafts, and it is very difficult to modify the parameters in later stages.It is recommended to choose equipment that supports a universal CAD / CAM interface, such as one that can directly import a SolidWorks model and automatically generate a cutting path.

Small tips for everyday maintenance.

Newly hired workers often forget that the bearings of the rotating shaft must be given a high-temperature grease lubricant every quarter.In particular, in the summer the high temperatures in the workshop cause ordinary grease to melt, which leads to the accumulation of dust.Another trick is to let the motor run for 30 seconds after each use, to cool down and extend the life of the motor.

What happens when a marker is out of place?

Don't start adjusting the laser head just yet! First check to see if the fixture is loose, and then use a dial indicator to measure the radial runout of the rotating shaft.If the error exceeds 0.02 millimeters, it may be that the drive belt is worn. Replacing the belt, which takes about 20 minutes, solves the problem.
