Laser Cutting

The Stiefelmayer laser is particularly well adapted to cutting precision shapes in thin substrates, including mild steel, stainless, copper and brass.  Motor laminations are a particular specialty and this fact matches the drive to EV in the American auto industry.

On average, thanks to the new 15kW laser, the cutting speed of the ByStar Fiber increases by up to 50 percent (when cutting with nitrogen) compared to a 10kW laser source. This means that sheet metal processing companies can benefit from higher productivity with relatively low unit costs. The 15kW laser output now also enables extended applications in stainless steel and aluminum up to 1.5 inch thick and thus offers maximum flexibility for customer orders.

The foundry-grade aluminum alloy, suitable for the laser powder-bed fusion (LPBF) process, enables 3D printing of parts that have traditionally been manufactured using casting practices. There are other Aluminum alloys that are more commonly used in metal additive manufacturing, such as AlSi10Mg, but Aluminum F357 can be anodized and shares characteristics with A356, a widely used casting alloy.

The LT722D, available with a 2.5kW Co2 laser source, can cut mild steel, stainless steel, and aluminum (some alloys).  The LT Fiber EVO, available with a 2 or 3kW fiber laser, can also cut these materials as well as copper, brass and galvanized steel.  Both versions handle bar weights up to 10.2 lb/ft (15 kg/m) and loading lengths of either 21’ or 28’ (6.5 or 8.5m) and unloading lengths of 11.5”, 15” or 21” (3.5, 4.5 or 6.5m).

A perfectly timed sequence becomes apparent for truck differentials, it consists of three individual parts before production starts: two housing parts and the ring gear. These each weigh up to 130 kilos (287 lbs) and have a diameter of up to 600 millimeters (24 in).
