Advantages Of Laser Fabricating

Laser Fabricating

This company specializes in short- to medium-run metal stampings and sub assemblies. Their laser helps with prototype and pre-production requirements.

Morrissey has been using a C02 Laser-Path Turbo-X48 manufactured by Mazak for several years. It has become evident that this technology is saving their customers money, decreasing turnaround time, and offering other conveniences.

No other cutting tool is as versatile as the laser. It can cut a wide variety of materials: carbon steel to 0.375" stainless steel to 0.187" bronze, aluminum, and titanium to 0.125" including: most plastics, woods, ceramics, rubber and neoprene. Roy Boeser, Morrissey's President explains why he went with the laser: "unique parts can be produced with minimum set-up time, making intricate prototypes not only economical, but also available with short lead times. Prototypes can be manufactured, fitted and manufactured again until the exact configuration desired is achieved."

The process uses no costly tooling. Part configurations are programmed by a CAD system and cut out in quantity from sheets of metal over four feet wide by eight feet long. Tolerance is very accurate (machine positioning accuracy is +/- 0.0004") and parts come off clean, normally requiring no expensive secondary operations. Typical programming time runs from one to three hours. It utilizes the worlds first "conversationally" programmed CNC system for laser machines. This, combined with its advanced mechanical construction, dramatically reduces set-up and programming time.

Some of their customers have found several advantages to using laser processing: parts can be manufactured without costly dies, turnaround can be quick (they have gone from prints to parts in as little as one week), it is ideal for JIT inventory programs, it greatly facilitates engineering, development and experimentation, and it is applicable to parts of varying intricacy, both precision and non-precision.

Like the turret press, the laser is ideal for prototypes, pilot runs, and moderate-volume production. When economical, they shift to a stamping process.
