Cutting Corners: The Idea Behind Power Ramping

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.

Laser Cutting Systems: Products

Laser Optics for Etching Metal

CO2 laser optics from Laser Research Optics feature coatings with < 0.2 percent total absorption values to keep them cooler. The silicon turning mirrors have an enhanced DBMR coating to provide up to 99.6 percent reflectivity. They are available off-the-shelf with 24-hour delivery, and priced according to configuration and quantity.
CO2 laser optics from Laser Research Optics promote sharper cuts with fewer passes and are optimized for 10.6 microns.

Fully Automated 3D Fiber Laser Tube Cutting System

The LT8.10 tube processing system is ideal for cutting highly reflective materials such as brass, copper and aluminum, and can process round, square, rectangle, flat oval and D-shaped tubes, as well as open profiles such as C- and U-shaped channel bar. Its new, exclusive ‘Tube Cutter’ 3D cutting head is perfect for tilt cutting of thick-walled steel, in tubes, and in open profiles and contours.
The flexible 3 kW LT8.10 fiber laser tube cutting machine from BLM performs extremely precise laser cutting on a variety of materials for tube diameters up to 9.5 in.

Economic Fiber Laser Cutting System for Small Shops

The Eagle eSmart laser cutting system comes in two variants: a Model 1225 with an area of machining axis 2,560 mm, 1,290 Y-axis and Z-axis 100 mm; and a Model 1530 with a machining area X-axis of 3,060 mm, Y-axis of 1,540 mm and Z-axis of 100 mm. These cutting systems achieve cutting speeds of 120 m/min and 2G acceleration. eSmart models are available with a laser fiber with a power of 1 kW to 4 kW. Tracking the laser beam is carried out using fault-free fiber. The new cutter is equipped with a body made of composite material, linear motors on all axes and pallet changer.
The Eagle eSmart from Power-Tech is ideal for small shops that want to bring fiber laser cutting capabilities in-house to eliminate outsourcing.
