Hand scraping

Hand scraping is a manual chip removal technique in which the size of the separated chips is only a few microns. It is extremely time consuming, requires a lot of expertise and years of practice from workers. It is the machining technique of plain bearings, machine tool beds, and dividing planes among others.

Fiber Laser

 

Its advantage over the CO2 laser is that the excitation is not done with high voltage current but with light, emitted by diodes. The beam is brought to the cutting site by optical fibers, so it can have up to five times of the energy density at the focal point compared to a CO2 laser of the same power, and the optics make it easy to control the laser light. Its very low material removal property is coupled with very low heat input, which makes it possible to create a scraped surface with it.
