Cutting with 60W isn’t possible. But you can ‘mark’, using various methods including etching off painted coatings, bonding a coating, such as Cermark or molybdenum disulphide (moly spray), bonding paint, bleaching anodised coatings, etc.
Even at higher wattages, laser cutting and ablation require specialised machines, capable of handling the extreme heat of molten metal as well as the fumes produced.
A high-wattage machine not designed for metal can easily crack lenses, coat mirrors and lenses and other parts with metal vapour.
There are cheaper options, one being fibre lasers with galvanometric heads. They can’t cut, but can natively engrave metal. And compound lenses can get the light pressure high enough to ablate metal, but at some cost in lenses and lens tube and there’s still the problem with excessive heat - reasonably easily overcome.
