Laser Cutting Systems

Create a Clean Pierce Point That is the Same Diameter as the Cut Width

This feature is important in cutting medical devices, electronics and fine mechanics components from thin materials with features that are too small to allow for piercing the drop-out scrap portion of the material.

Cutting Corners: The Idea Behind Power Ramping

A cut made without the power ramping feature. Power ramping is typically meant to be used when cutting with air or nitrogen in thinner materials that are 3 mm (0.12 in) thick or less. The best applications are in thin to mid-range material when nitrogen is used as the assist gas to increase the edge quality when cutting large contours. The power ramping feature is not as beneficial when cutting with oxygen because of changes to the properties of the assist gas and the decreased feed rates that occur.  
Although power ramping has proven to be highly beneficial, it is often underutilized on the shop floor because fabricators either do not understand its benefits or they just don’t know how to use it. By simply applying the given values and principles presented here, they will see a visible improvement in corner and radii cut quality.

Lasers Handle Cutting and Welding of Complex Parts

The Morgan 3 Wheeler car build in the Premier shop, which used AutoForm simulation to arrive at the 2D shape for each blank, which was then laser cut ready for forming. The shop produced 1,500 sets of bodywork panels at the high speed of laser cutting to keep costs down.
This shop welded the seam and cut 100 million holes in 12,100 torches – in six months. That's not all. Check out the automotive parts they're making.

Laser Marking 101

Laser marking a bevel gear. Lasers have a number of advantages over traditional inkjet printing, etching, mechanical engraving, and stamping. They can mark a wide array of materials, from ferrous and non-ferrous metals to organic materials such as thermoplastics and elastomers, with high marking quality and speeds, minimal effect on material, consistent results, and no tool wear. 
How do you choose the appropriate laser for your marking applications? Here are several factors that must be considered and how they impact the end results.

A High Fiber Diet

The Optiplex Fiber II 6 kW fiber laser cutting system from Mazak Optonics offers superior edge quality, more stable cut performance and greater throughput for processing stainless steel, copper, brass, bronze, aluminum, hastelloy, inconel, titanium, thin gage mild steel, and other exotic metals. There is no need for additional surface cleaning when painting mild steel cut with nitrogen. 
Fiber laser cutting systems are sweeping through metal fabrication shops because they are faster, more consistent, more cost effective, and more competitive.

What You Must Know About Single Mode Fiber Laser Markers

Figure 1.  Single mode and multi mode laser intensity and beam diameter. Single mode lasers have the best beam quality laser, with M2 values around 1.1-1.2.  Lasers with M2 values above this are considered multi mode (higher order). The fiber laser naturally produces a high quality beam, so on paper the differences may appear small, but they are huge in processing terms.
The single mode fiber laser marker has best-in-class beam quality that translates to fine marking capabilities plus effective micromachining for drilling, cutting, scribing, ablation for a variety of applications.

Amada Miyachi America Donates Laser to Workshop for Warriors

The LMWS laser marking workstation donated to WFW by Amada Miyachi America. The system requires only minimal workspace and is perfect for teaching students skills needed for low volume production and research and development environments in the automotive, medical, aerospace, electronic components, and battery industries. They will also use the laser to engrave items for visitors and donors, and to demonstrate their programs at such industry events as the San Diego Maker Faire and FABTECH.
The new LMWS laser marking workstation will be used to train students how to mark metals, ceramics, and many plastics.
