Depending on the manufacturing task at hand, a
user can choose the most productive manufacturing
method. This amounts to flexibility for fulfilling vary-
ing requirements, cost efficiency, and competitiveness. The machine’s fiber laser source has low-energy
consumption and eliminates the need for laser gases.
The company required a machine that needs to
be flexible and extremely fast for a quick response
to production orders, often for very small quanti-
ties. To that end, the LPe6f laser/punch combination
machine offers versatility and flexibility, combining
multiple operations in one machine. This lean man-
ufacturing style reduces cost per part, as parts will
be made fast, easily, and accurately by one operator
using only one operating and programming system.

combines servo-electric punching and fiber laser
technology to fabricate challenging products.
The following paragraphs describe the machine’s features and capabilities:
High-performance punching. The machine’s premium
series turret punch press has properties such as auto-
matic tool length measurement, optimization of stroke
length, and easy adjustment of the punching stroke.
These combine with others, adding up to faster setups
and more ease of operation. The punching speed, tool
rotation, and tool change time are improved. The punching stroke is numerically controlled, providing high-performance punching and excellent forming capabilities.
“The speed of the servo-electric punching is so
much faster,” Aronson says. “There is also less main-
tenance than the older hydraulic model. In addition,
the servo-electric operation has lowered our power
consumption by approximately one third. The forming
station has also been a really good tool for us in that
machine. It allows us to perform a great deal of upform-ing, extruding, and tapping, eliminating costly secondary operations.”
Fiber laser cutting. The laser used in the system is a
4k W high-brilliance fiber laser (FIGURE 3). Cutting speed
increases in proportion to power and a wide range of
material can be cut, such as copper or brass. A significant reduction in operating cost is achieved because
the laser has no maintenance requirements, no laser
gas is needed, and energy consumption is far smaller
when compared to other solutions.
Cutting with nitrogen. “Our largest customer is in
the fitness equipment industry and mandates that if we
cut with CO2, all traces of the laser oxide edge must be
either mechanically or chemically removed,” Aronson
