Micro Laser Cutting Head
Micro laser cutting heads provide the ideal solution for micro-machining applications which require small spot sizes and high-resolution focus adjustment. The combination of micro laser cutting head’s internal optics and its completely sealed architecture provide long term stability of both focal plane and beam quality even at high laser powers. Micro laser cutting heads are plug and play with all lasers providing ease of integration and service.
Advantages Of Micro Laser Cutting Head
Non-contact cutting
Micro laser cutting heads enable non-contact cutting, eliminating the need for physical contact between the cutting tool and the workpiece, which reduces the risk of damage to delicate materials and allows for cleaner cuts without tool wear or contamination.
Precision and accuracy
Since laser beams can be focused, this allows precise drilling of small holes that conventional drilling cannot achieve. The hole depth can be controlled even for micro-scale holes. All parameters can be automatically controlled, producing consistent and repeatable results.
Fast drilling speeds
Since there is no required tool positioning against the workpiece, drilling speeds only depend on the configuration of the optical system and the movement of the cutting head. Moreover, the complexity of the profile to be cut has minimal effect on the incremental cost of operating the machine.
Suitability for difficult materials
Lasers can cut and drill different materials that are difficult for conventional machining. Lasers can cut high-strength metals such as titanium and steel superalloys. Aside from these high-strength metals, micro laser cutting head is used for cutting crystals, ceramics, and even diamonds because of its ability to do controlled fracture.
What Materials can the Micro Laser Cutting Head cut?
The micro laser cutting head process can be applied to a multitude of materials (metals, composites, polymers, carbon, etc.), including very delicate materials like mother of pearl, silicon, ceramics or for machining glass. But it can also be used with hard materials like ruby, diamond or sapphire. The interaction between laser and material is virtually athermal, with no alteration of the base material. There will be no alteration (visual, chemical or metallurgical) or damage to the material.
What is the Cutting Accuracy of the Micro Laser Cutting Head?
The machine performs laser beam micromachining with a foundation of granite and direct drive of the axes, ensures a high process stability and a precision of the cutting in the level of ± 0.01 mm, depending on the material and material thickness. The micro laser cutting head is perfect for precision laser cutting, micro laser welding, laser micro drilling and micro structuring of micro laser cut components.
Maintenance Tips for Micro Laser Cutting Head
Check the cutting head
Every component of your micro laser cutting head is critical to performing well and consistently producing high-quality cuts. Left unchecked after each run, this incredibly fragile part will eventually become damaged. Check and clean the laser cutting head before and after every use to avoid costly damage to the cutting head.
Inspect the laser lens and mirrors
These two components are crucial in laser cutting. Over time, these two components become dirty or damaged. Therefore, you can use any laser-cleaning solution to clean these components. In this case, ensure that this cleaning equipment is free of debris, dust, or other contaminants.
Lubricate
On top of checking that no debris can affect the operation of the machine, you should also ensure the guide rails are properly lubricated. Cleaning them regularly also ensures that debris does not get onto the track and cause problems. But proper lubrication is also essential for the machine to have consistent, even movements.
Inspect damage or wear
You should check for loose bolts, screws, or electrical connections. In addition, it is also crucial to make sure all safety enclosures are in place and secure. Also, inspect the lens is clean.
Check the alignment and focus of the laser Beam
After cleaning, inspect all the components and check the alignment. If needed, adjust the direction of the laser beam. The misaligned laser may create inaccurate cutting. Ensure that the machine’s control parameters are correctly set.
How to Prevent Micro Laser Cutting Heads From Burning Materials
If there are burn marks on the back of the wood, it may be because of the surface or bed under the laser machine. When a laser machine is carving or cutting an object, smoke flows through the bottom of the object. It causes visible burn marks. Therefore, a suitable panel is needed to provide optimal ventilation and easy passage of smoke. Usually equipped with honeycomb panels to indicate that the cutting space is not closed, can increase the speed of air flow, because the laser generated heat is deposited downward, this honeycomb panel below the carved area heat or smoke heat can also be lost.
