In the field of precision machining, "only fast and not breaking" seems to have become an iron law: to improve accuracy, we must talk about picoseconds; "Millisecond-level" is often mistaken for an old thermal processing technology, which is only suitable for processing thick plate coarse. But is this really the case? If you're machining thin metal parts (0.1-1mm) and still obsessed with picosecond lasers, chances are you're paying a high price for "over-provisioning". Today, we want to correct the name of the millisecond laser - it is the seriously underrated "king of efficiency and cost-effectiveness".
Is picosecond laser really a necessary choice? Many customers ask for "picosecond cuts, no burrs and no heat effects". Although picosecond lasers can achieve near-zero thermal impact, they are expensive equipment, slow processing speed, and high maintenance costs, and the cost per piece can reach 5-10 times that of millisecond pole lasers. Modern millisecond-level lasers can reduce the heat-affected zone to less than 0.1mm through pulse shaping technology and high peak power control. For most metal structural parts under 2mm, this does not affect the appearance and function at all.

Efficiency crushing: the "fast knife" philosophy of millisecond-level lasers The core advantage of millisecond-level lasers is high single pulse energy. In the face of thin plates below 2mm, it is like "hot knife cutting butter", piercing with one blow; Picosecond lasers, on the other hand, are like "water gun scouring" and have lower efficiency. With the same precision, millisecond laser cutting speeds can reach 40-60m/min, with 3-5 times the efficiency of picosecond lasers. Especially when making micro-holes, the hole wall is smooth, there is no recasting layer, and the time is greatly reduced. This means faster order delivery, significant capacity gains, and significantly shorter equipment payback cycles.
Epilogue High precision does not mean that it has to be costly. In the field of thin plate precision machining, millisecond lasers are becoming the "invisible profit engine" of more and more enterprises with real efficiency, reliable quality, and lower comprehensive costs. Only by choosing the right technology can we truly transform "high precision" into "high profit".
