In order to make high-precision parts using laser cutting, dimensional accuracy is of utmost importance. There are several factors that affect the precise movement of the laser beam. The first one is the control system, which must be capable of processing accurate signals. The second one is the driver, which should finely position the laser beam. In addition, the laser cutting parts must be dimensionally accurate, so that the lead screws and the transmission system can mate properly. Deburring the parts produced by laser cutting Romania can also improve the transmission system.
Carbon dioxide
A CO2 laser is used in cutting processes. Its two types of modes are pulsed and continuous. Pulsed mode delivers high energies of about 400 to 500 watts during a single exposure. Continuous mode delivers higher energies but requires a longer exposure time. The CO2 laser can be used for cutting large warts, visible verrucae, and residual HPV in surrounding skin. Here are the main applications of CO2 laser cutting.
Fiber
A laser that can cut fiber is a highly versatile tool. It can cut any material, from thick materials to thin, and the wavelength of the beam is much shorter than that of CO2 lasers. This results in less wear and tear on the machine, and the fibre laser also gives better cutting results on metals and other reflective materials. In some applications, such as medical devices, it can even be used to cut electronic sensors. Lasers that use fiber optic technology can be used to cut plastics, glass, and even metals.
Thermal stress fracture
Thermal stress fracture is a mode of material removal that occurs in structural ceramics during laser cutting. The thermal stresses produced are typically higher than the fracture strengths of structural ceramics and are sufficient to form microcracks that grow during subsequent heating/cooling cycles. The fracture mode of laser cutting is therefore the best option for removal of hard materials such as glass and metal. But it is important to note that this fracture mode is only applicable for metals, and other materials such as plastics are not affected.
Pulsed beam
The ultrashort pulsed laser can cut a variety of materials, including nonferrous metals, composite materials, glass, and ceramics. Pulsed laser cutting can also cut material with a thickness of two millimeters or less. A 20-W nanosecond laser can deliver a high-quality cut finish. The process is versatile and can cut multiple materials in a single step. The following is a list of applications where ultrashort pulsed laser cutting is useful.
Continuous wave
There are two primary types of lasers: pulsed and continuous wave. Pulsed lasers generate extremely short pulses, and continuous wave lasers produce longer pulses. Both types of lasers can effectively cut steel, but pulsed lasers produce a higher rate of material vaporization and waste heat in the process. This article will examine the different types of lasers and how they differ. Let’s also discuss the advantages of continuous wave laser cutting.
